Frequently Asked Questions - AKEV160 Air King

How do I clean or replace the filters on my Air King AKEV160?

Open the front cover and slide out the filters. For polyester filters, vacuum every 3 months and replace every 1–3 years. For optional MERV filters, replace every 3 months. Always note the airflow direction when reinstalling.

How do I balance the airflow of the ERV/HRV?

Use a magnehelic gauge or differential pressure manometer. Measure pressure at the exhaust and fresh air ports, then adjust fan speeds using the push buttons on the control board. Aim for airflows equal or within 10% of each other. Refer to the airflow chart on the unit door.

What do the different operation modes mean?

Modes include Off, Standby, Low Speed, High Speed, 20/40 Cycle (20 min low, 40 min standby), Recirculation (no outside air), and 20/40 Recirculation. The humidity sensor can temporarily override to high speed in most modes.

How do I set the humidity level on the wall control?

Press the up/down arrow keys until the humidity percentage flashes. Adjust in 5% increments. When ambient humidity exceeds the setpoint (range 20–80%), the unit runs high speed until humidity drops. Typical winter setting: 40–60%.

Why is there frost or ice buildup on the unit or ducts?

Possible causes: unbalanced airflow, blocked ducts, or a faulty defrost system. Balance the airflow and ensure ducts are insulated. Minimal frost is normal before the defrost cycle activates. If persistent, check the defrost function and contact a qualified technician.

Can I connect the AKEV160 to my furnace?

Yes, for extended exhaust or simplified systems. You must interlock the furnace fan to run during ventilation. Refer to Section 7 of the manual for wiring diagrams. Do not connect to kitchen range hoods, dryers, or combustion appliance ducts.

INSTALLATION INSTRUCTIONS

CAUTION: MAKE SURE UNIT IS UNPLUGGED BEFORE STARTING INSTALLATION.

WARNING: TO REDUCE THE RISK OF FIRE, REMOVE ANY SHIPPING MATERIAL THAT MAY BE PRESENT INSIDE THE UNIT.

SECTION 1

Preparing the Installation Area

CAUTION: INSTALLERS ARE RESPONSIBLE FOR THE PERFORMANCE OF THE VENTILATION SYSTEM AND FOR ENSURING THAT ALL CODES AND STANDARDS ARE MET.

1. Ensure that all the following conditions are met:

a) Do not mount the fresh air supply near a source of contaminated air such as automotive exhaust, gas or propane exhaust, garbage containers or oil tanks.
b) Do not connect a dryer exhaust to an ERV/HRV.
c) Combustion appliances such as furnaces and water heaters must not draw combustion air directly from an ERV/HRV.
d) Do not connect a kitchen range hood to any part of this system.
e) Do not install in attics or other unconditioned spaces (min. 61° F).
f) Do not install in enclosed garages.
g) Maintain straight duct runs as much as possible, using as few joint fittings as possible.
h) Keep use of flexible ducting to a minimum.
i) Be sure to observe local codes regarding running and insulating ducts in unconditioned spaces.
j) Poorly insulated ducts run in unconditioned spaces will hamper the efficiency of the unit.

SECTION 2

Installation Options

CAUTION: INTERCONNECTION WITH A FORCED AIR FURNACE DUCT SYSTEM IS PERMISSIBLE; HOWEVER, YOUR ERV/HRV IS NOT INTENDED TO BE CONNECTED TO ANY OTHER EQUIPMENT OR APPLIANCES.

NOTE: When selecting an installation option, consideration should be given to the increased electrical consumption of the furnace fan. The way your ERV/HRV is installed may make a significant difference to the electrical energy used. To minimize the electricity use of the ERV/HRV, a stand-alone fully ducted installation is recommended. If you choose a simplified installation that operates your furnace air handler for room-to-room ventilation, an electrically efficient furnace that has an electronically commutated (EC) variable speed blower motor will minimize your electrical energy consumption and operating cost. Installing a user-accessible control with your product will improve comfort and may significantly reduce the product's energy use. Most building codes require a centrally located control with an on/off switch.

Fully Ducted System

1. This system uses an independent duct system for supply and exhaust air. The ERV/HRV is controlled independently of all other equipment. The best results are achieved when:

2. Each room of the space is serviced with a vent mounted in the ceiling or high on an interior wall (within 12" of the ceiling).

3. Vents are located deep within a room, where they will not short circuit or create an uncomfortable draft.

1. Extended System, Continuous Ventilation: The furnace fan may not need to run continuously with this system. Check local code requirements. For improved supply air distribution during continuous ventilation mode, the furnace may be interlocked to the ERV/HRV. See Section 7 for interlock wiring and settings and Section 10 Control Wiring and Options.
2. Extended System, Intermittent Ventilation: If the ERV/HRV is operated intermittently, the furnace fan should be interlocked with the ERV/HRV for good distribution of supply air during high-speed ventilation conditions.

Simplified System

1. This system uses the furnace's return plenum for both supply air distribution and exhaust air collection. The exhaust air connection must be a minimum of 40 inches upstream of the supply air connection to avoid short circuiting of the fresh air.

1. Simplified System, Continuous Ventilation & Intermittent Operation: For proper supply air distribution with this system, and to prevent short circuiting in the return air duct, the furnace fan must run during ventilation mode. Interlock the furnace and unit in accordance with Section 7.

SECTION 3

Preparing the Unit

1. Unpack unit from the carton and confirm that all pieces are present. In addition to the unit you should have:

Standard Filters Anti-Vibration Straps Removable Terminal Block

8 - Washers 4 - ½ Screws Drain Hose Assembly (HRV ONLY)

Core RVC8 Control Switch Instruction/Safety Sheet

1. Choose the location for your unit. To ensure the best air and sound performance, it is recommended that the length of ducting and the number of elbows be kept to a minimum, the radius of each elbow be as large as possible for the installation, and that insulated hard ducting be used. The unit is designed to mount from the ceiling using the included anti-vibration mounting straps. Avoid mounting the unit under bedrooms or other quiet areas.

NOTE: The unit must be installed into a location that can be easily accessed once installed.

1. No additional vibration deadening materials are needed for this fan.

SECTION 4

Mounting the Fan

1. Using appropriate sized mounting screws at least #8 x 1.5" (not included) insert through the included washers and hanging strap grommets, then fasten to the mounting surface. If mounting to a material other than a wood joist use an appropriate mounting method as determined by a professional.
2. Insert the included screws through the washers and bottom grommets of the straps, then fasten to the unit.
3. Pull down vertically on each strap while lifting the bottom of the unit. Level the unit from right to left and front to back.
4. To loosen strap, lift up on the buckle.

NOTE: Support unit and gently lift as you tighten each strap.

SECTION 5

Ducting

CAUTION: ALL DUCTING MUST COMPLY WITH LOCAL AND NATIONAL BUILDING CODES.

NOTE: The ducting from this fan to the outside of the building has a strong effect on the air flow, noise and energy use of the fan. Use the shortest, straightest duct routing possible for best performance, and avoid installing the fan with smaller ducts than recommended. Insulation around the ducts can reduce energy loss and inhibit mold growth. Fans installed with existing ducts may not achieve their rated air flow.

WARNING: MAKE SURE THE FRESH AIR INTAKE PORT COMPLIES WITH ALL LOCAL AND NATIONAL CODES AND IS LOCATED AT LEAST 6 FEET AWAY FROM SOURCES OF CONTAMINATION SUCH AS BUT NOT LIMITED TO: DRYER, FURNACE OR CENTRAL VACUUM EXHAUSTS, GAS APPLICANCES SUCH AS BBQ GRILLS, GARBAGE BINS OR OTHER EXHAUST PORTS.

NOTE: To ensure quiet operation of in-line and remote fans, each fan shall be installed using sound attenuation techniques appropriate for the installation. For bathroom and general ventilation applications, at least 8 feet of insulated flexible duct shall be installed between the exhaust or supply grille(s) and the fan.

1. Connect the ducting to the unit's duct collars. Seal ducting to collars with appropriately rated tape. Use screws or suitable clamps to secure in place. Make sure the fresh air intake is connected to a properly installed intake port that is a suitable weather hood with insect screen to protect air intake. It is recommended that low restriction termination fittings be used.

1. Ensure duct joints and exterior penetrations are sealed with caulk or other similar material to create an air-tight path to minimize building heat loss or gain and to reduce the potential for condensation. Place/wrap insulation around duct and/or fan in order to minimize possible condensation buildup within the duct, as well as building heat loss or gain.

SECTION 6

Drain Connections (HRV Units Only)

Access to a drain or sump is required for condensate. Care should be taken to run the condensate tube where it cannot freeze. To install the drain assembly:

1. Apply the rubber O-ring supplied to the flange of each drain spout.
2. Insert the drain spouts through the holes in the drain pan.
3. Use the provided nut to tightly secure the drain spout.
4. Cut two lengths of 1/2" ID drain hose long enough to avoid kinking.
5. Attach the hose to the drain spout by sliding it over the spout until it is tight to the bottom of the nut. Repeat for the other side.
6. Secure the hose to the spout with the plastic tie wraps.
7. Install the Tee Fitter in either of the two ways shown in the drawings.
8. Attach the free end of the hose to the left fitting. Repeat for the other side.
9. Use the remaining hose to form a "P" trap and terminate at the top of the tee.
10. Pour approximately one cup of water into the drain assembly to form an air seal. This prevents gasses from being drawn into the unit.

NOTE: For single-drain units your unit might be equipped with just one drain and one drain plug. For these models, use the drain hose to form a P-shape after connecting the hose to the drain plug (the arc of the P should be wide enough so as not to cause a kink in the drain hose). Fix the P-shape with one of the (two) plastic cable ties provided, taking care not to pinch the hose when tightening the cable tie.

SECTION 7

Furnace Interlock

CAUTION: MAKE SURE UNIT IS UNPLUGGED BEFORE STARTING INSTALLATION.

CAUTION: ALL ELECTRICAL CONNECTIONS MUST BE MADE IN ACCORDANCE WITH LOCAL CODES, ORDINANCES, OR NATIONAL

ELECTRICAL CODE. IF YOU ARE UNFAMILIAR WITH METHODS OF INSTALLING ELECTRICAL WIRING, SECURE THE SERVICES OF A QUALIFIED ELECTRICIAN.

For simplified (return/return) duct systems, it is mandatory that the unit be interlocked with the furnace blower such that the furnace fan runs when the unit is on to distribute supply air throughout the space. For extended exhaust systems, furnace interlock is recommended. Refer to local building codes.

If the standard interlocking method has the unwanted effect of bringing on the AC, i.e. thermostats that do not isolate "G" from "Y", use the alternate method shown above.

Depending on local Building Codes, you may choose to interlock whenever the unit is operating at any speed, or just high speed. Position 5: interlock at any unit speed; Position 6: interlock at unit high speed only.

NOTE: One jumper must be present in jumper range 1-4 and in jumper range 5-8. DO NOT alter jumper set 3.

SECTION 8

Balancing Air Flows

Once the ERV/HRV system is installed and the vapor barrier is completed, ensure the following:

1. Close all windows, doors and fireplace dampers.
2. Turn off any exhaust systems such as dryers, range hoods, bath fans and central vacuums.
3. With multiple-speed forced air furnaces in Extended or Simplified systems, the furnace should operate at continuous low speed.
4. During balancing, activate high speed on the unit by remote control or by temporarily installing a jumper wire between R and Hi on the unit's 10-wire, 24 VAC terminal block.

NOTE: If optional air filters are added at a later time, the unit's airflow will need to be re-balanced.

To balance the air flows, you will need a device to measure air flow. It is recommended to use either a magnehelic gauge or differential pressure digital manometer capable of measuring 0 to 0.5 inch of water (0-125 Pa). Depending on the device you are using, follow one of the two procedures below.

Magnehelic Gauge and Flow Grid:

1. Disconnect the flex connector from the rigid duct before any branch ducts. Compress the flex duct and insert the flow grid. Tape the joint between the flow grid and ductwork.
2. Mount the magnehelic gauge level and plumb. Join the hoses from the flow grid to the magnehelic gauge. The needle of the magnehelic gauge should read positively. Switch hose connections if the needle falls below zero.
3. Record reading from gauge and adjust the motor speed to the desired CFM.
4. Repeat the procedure for the next duct. Adjust motor speeds until air flow readings are equal or within 10% of each other.

Differential Pressure Manometer or Magnehelic Gage and Units with Pressure Ports:

1. Before placing the manometer, reset it to zero. If using a magnehelic gage, ensure the gage is placed plumb and level.
2. According to the air flow to be measured, connect tubing from instrument to EXHAUST air flow or FRESH air flow pressure taps (see illustrations at right).
3. If the readings on your instrument drop below zero, reverse the tubing connections.
4. Take and record pressure readings from each air stream, consulting the air flow chart mounted on the unit's door to determine air flow.
5. Balance air flows so that they equal or within 10% of each other.

NOTE: P/Airflow values are different for exhaust and supply air streams.

Unit Airflow Chart

Adjusting Fan Speed for Balancing and Capacity Requirements

For high-speed adjustment/balancing, use any means to initiate high speed (e.g. ES-M1, R—Hi jumper wire, or engage 24V R—Hi control), then:

1. Press and hold either the FRESH air or EXHAUST air push buttons (not both) for 3 Seconds to initiate SPEED ADJUST MODE.

2. Press the corresponding button to adjust the fresh air fan or the exhaust fan speed, thereby changing the air flow. Each press reduces motor speed until the default minimum is reached, at which point the motor will return to its peak speed. Allowing a brief pause between presses (about 0.5 seconds), you will press the adjust button about 70 times before reaching minimum speed. During the bala adjusting the fresh air motor or exhaust air

3. To exit balancing/speed adjust mode, stop pressing buttons for 10 seconds. This will place the unit back in operating mode with the new speeds saved to the circuit board's memory. Low-Speed Adjustment/Balancing. If low speed adjustment is desired, use a jumper wire (R—Lo) or remote control to put the unit into low speed and follow steps 1-3.

SECTION 10

Installing the Wall Control

Your unit includes a model RVC8 wall control. Your unit can also accommodate other 24 VAC controls and can be connected in Series or Parallel.

CAUTION: IF INSTALLING OTHER 24 VAC CONTROLS FOLLOW ALL INSTRUCTIONS INCLUDED WITH THE CONTROL AS WELL AS ANY LOCAL OR NATIONAL CODES THAT MAY APPLY.

CAUTION: FOR UNITS WITHOUT A RECIRCULATION DAMPER, TURN OFF RECIRCULATION FUNCTIONS IN CUSTOM SETTINGS.

WARNING: ROUTE CONTROL WIRING ACCORDING TO LOCAL BUILDING CODES.

Mounting the Control

1. Mount in a central location within the building.

2. Fits a standard 2" x 3" (nominal) electrical wall box (not included). While your wall control comes with a screwless face plate, you can substitute it with another to match any décor by using a flat screwdriver to pry off the original face plate and by removing the 5 mm screws securing the faceplate base.

3. Drywall anchors may be used where a wall box is not available.

Wiring

1. Using a 3 mm flat head screwdriver, connect 4-conductor wire to the 12 VDC (4-wire) removable terminal block provided. Wiring the controls involves simply matching terminals on the control to those of the ERV/HRV terminal block (see right).

In cases where humidity control is not desired or practical, use the arrow keys to toggle the humidity "setpoint" to one click above 80% or one click below 20%. Also use arrow keys to reactivate humidity control.

NOTE: Generally, a humidity setting of 40-60% is desired. While your ventilator is not a dehumidifier, ventilation can have the effect of reducing indoor humidity when exchanging moisture-laden air from the interior space with less humid, fresh air from outside.

OPERATION MODES

OFF: Ventilator is off, but the control itself is on and will display ambient humidity level.

STANDBY: Ventilator is idle. During this mode, a static pause icon will display. During standby mode the ventilator will temporarily switch to high speed on demand from the lumina humidity sensor or a timer.

LOW SPEED: Ventilator runs in low speed continuously. During this mode, an animated 3-blade fan will display. During low speed mode the ventilator will temporarily switch to high speed on demand from the lumina humidity sensor or a timer.

HIGH SPEED: Ventilator runs in high speed continuously. During this mode, an animated 6-blade fan will display. Ventilator will remain in high speed on demand from the lumina humidity sensor or a timer and continue in high speed after the humidity/timer demand is met.

20 LO/40 STANDBY: Ventilator cycles continuously between 20 minutes of low speed operation and 40 minutes of standby operation. During low speed cycle, the fan 3-blade fan icon will animate and the pause symbol will flash twice every 5 seconds. During the standby cycle, the pause icon will be static and II flash twice every 5 seconds. During 20 lo/40 standby mode the ventilator will itch to high speed on demand from the lumina humidity sensor or a timer.

RECIRCULATION MODES

RECIRCULATION: Ventilator continuously recirculates air within the home and does not bring in air from outside, i.E. Air exchange does not occur. During this mode an animated cycling arrow will display. During recirculation mode the ventilator will temporarily switch to high speed on demand from the humidity sensor or an external timer.

20 LO/40 RECIRCULATION: Ventilator cycles continuously between 20 minutes of low speed operation and 40 minutes of recirculation operation. During the low speed cycle, the fan will animate and the recirculation ring will flash twice every 5 seconds. During the recirculation cycle, the recirculation arrow will animate and

the fan icon will flash twice every 5 seconds. During 20 lo/40 recirculation mode the ventilator will temporarily switch to high speed on demand from the lumina humidity sensor or a timer.

For timed high speed operation, press the hourglass button once for 20 minutes, twice for 40 minutes, or three times for 60 minutes. Hourglass icons will appear from left to right at the bottom right of the LCD display and a high speed fan icon will appear on the screen. After 3 seconds of

no button activity the high speed cycle will begin. As each 20 minute cycle expires, one hourglass icon will disappear from right to left. You can manually turn off the timer cycle by pressing the hour glass button until all the hourglass icons disappear.

If you would like to view or change modes during a high speed call, simply use the mode and arrow keys and the chosen mode will resume/commence after the timer cycle has expired.

NOTE: Additional timers are compatible with your control, however, the control will not indicate that these external timers are active (i.E. It will continue to display present mode of operation only). You can change the desired mode of operation during a timer cycle; it will commence after the timer cycle has expired.

MAINTENANCE INDICATOR/RESETTING MAINTENANCE CLOCK

Your control has a maintenance run clock (it only counts time when the ventilator is turned on). Factory default for the maintenance clock is 3 months, at which time a wrench icon will appear in the upper right of the LCD screen and a yellow led will light. This indicates that it is time to check your ventilator to see if it needs cleaning and to see if your filters

20/40

need to be cleaned or replaced. Press and hold the power button for 5 seconds to reset the maintenance clock. Some units feature a red LED that will light after 3 months if the initial service reminder is not turned off.

If the electrical service to the ventilator is for some reason interrupted, the mode of operation active in the wall control at the time of the interruption will resume when the electrical service to the ventilator resumes. Any custom settings will have been saved.

CUSTOM SETTINGS

The control allows adjustments to customize its use for unique circumstances. Any of these changes are written into the control's memory but can be changed an infinite number of times. We recommend that only a qualified technician make these adjustments as they can affect the nature of the ventilator's performance. The customizable features include:

1. Adjusting the run time of the maintenance clock
2. Calibrating the humidity sensor
3. Turning off/on recirculation functions.

To access the custom settings menu, simultaneously press and hold the up and down arrow buttons for 15 seconds. You will note that the backlight would have turned on after 10 seconds. Once in the custom settings menu, use the arrow buttons to navigate among choices for a given setting. Pressing the mode button will preserve factory settings or initiate any change and will move you on to the next customized feature. After 5 seconds of no button activity, current settings will be written and the control will resume regular operation as programmed.

Once you are in the custom settings mode the first option will be maintenance clock. You will see the factory setting of this feature: 3 months. To keep factory setting, press the mode button or use the up and down arrow buttons to change the setting in the range of 1-12 months. Once any desired change to the setting is in place (if any), press the mode button.

CALIBRATING THE HUMIDITY SENSOR

If calibration is not desired, skip this step by simply pressing the mode button to keep factory calibration active. If calibration is desired, use the up and down arrow keys to calibrate the humidity sensor in 5% increments. To program any changes, press the mode button.

TURN OFF/ON RECIRCULATION FUNCTIONS

You will now see an animated recirculating arrow indicating that the recirculation by factory default is enabled. Use the up and down arrow keys to turn off the recirculation functions (static arrow) or on (animated arrow).

As noted previously, recirculation functions must be turned off for use with ventilators that do not have a recirculation damper. For such units, use of recirculation functions would only result in full-time, low-speed operation.

SECTION 12

Start-Up

1. Ensure the controls are connected in accordance with Section 7 and/or 10.
2. For electrical hook-up, plug into a properly grounded 120 volt receptacle.
3. Ensure that the machine is piped to an adequate drainage source, i.e. through the drain hose supplied.

SECTION 13

Operating Your System

It is recommended that the unit run on low speed at all times to ensure a steady supply of fresh air and removal of indoor pollutants. How much a home needs ventilation can depend on several factors such as number of inhabitants, cooking habits, hobbies, presence of pets, opening windows, etc. so no two households are necessarily the same for the amount and frequency of ventilation they need. Observance of moisture on windows, lingering odors and a sensation of stuffy, stagnant air are all signs for the need of ventilation in general or increased ventilation in specific cases. The controls for your ventilation system offer means to regulate how much and how often the home is ventilated.

The included control is equipped with a dehumidistat, or "d-stat". A d-stat monitors ambient relative humidity (RH) and has selectable settings, generally 30%-80% RH. When ambient

humidity is detected above the setpoint, it will trigger high speed in the ventilator. The unit will run in high speed until the ambient air returns to the setpoint RH. Your ventilator is not a dehumidifier, however ventilating can have a dehumidifying effect by simply removing high RH air from the space, particularly during cooler/cold seasons when outdoor humidity is typically lower than indoor humidity. Typical dehumidistat settings are as follows:

Winter Operation: 40% - 60%. Lower settings may be necessary in colder zones to keep windows free of condensation. If you notice the air is uncomfortably dry in winter, you might set humidity to a higher level or choose an operation mode above which operates the ventilator less or for shorter periods.

Spring/Fall Operation: 50% - 60%.

Summer Operation: For air conditioned homes run the ERV/HRV as recommended for winter operation, i.e. continuous low speed or use a 20/40 setting. In homes without air conditioning, there is no need to run the ERV/HRV during the day when windows are open. If the ERV/HRV is connected to the bathrooms(s) or kitchen, use the standby setting. The typical dehumidistat summer setting is 65%-80% or OFF.

SECTION 14

Use and Care

CAUTION: MAKE SURE UNIT IS UNPLUGGED BEFORE SERVICING.

NOTE: Exact location of components will vary according to the specific unit.

Isometric technical drawing of a mechanical housing with labeled components (A, B, C, D), no readable text or symbols present.

1. Filters (A): Dirty filters can reduce ventilation efficiency, result in unbalanced airflow and damage or shorten the life of the motors. Filters are located either on top or below the core depending on your exact model and remove easily by opening the front cover of the unit and sliding out.
   Polyester Filters: Vacuum every three months. Replaced every 1-3 years.
   Option MERV Air Filters: If optional air filters have been installed, they should be replaced every 3 months. When replacing, take special note of the airflow direction.
2. Fan (B): Wipe all parts with a dry cloth or gently vacuum the fan. NEVER IMMERSE ELECTRICAL PARTS IN WATER. No other service is required as these fans are designed to operate continuously without lubrication.
3. Condensate Drain (C) (HRV UNITS ONLY): Twice per year wipe clean the condensate drain pan. Check the condensate drain and tubing to ensure they are free flowing. The tubing must have an "S" or loop that traps a quantity of water to prevent air from entering the unit via this tubing.
4. Recovery Core (D): The core (located behind the cover) should be removed and cleaned at least once a year. Unlatch the latch(es) and slide the door to right to release from hinges and clean as follows:

ERV Units: Clean by vacuuming at least once a year. DO NOT USE SOAP, WATER OR ANY CLEANING AGENTS ON THE FIBER-MEDIA CORE.

HRV Units: Clean using a mild detergent in cold water at least once a year. Make sure the core is completely dry before re-installing into the unit.

When re-installing the core make sure the arrow on the core is pointing to the top of the unit.

1. Exterior Hoods: Regularly check the outside vents and clean any obstructions such as grass, leaves or other debris. Do not replace the screen with mesh smaller than 1/4" as this will restrict airflow. During winter operation, ensure snow and frost does not build up and restrict or block openings.
2. Grills & Duct Work: Clean the grills when they are dusty or greasy with soap and water. Check for punctures in the insulation jacket on the fresh air and exhaust air ducts. Repair any punctures using foil tape.
3. Annual Servicing: Your ERV/HRV should undergo annual general servicing by an accredited contractor. This servicing should include the following:

a) The six maintenance items above.
b) A general check for proper operation. Controls and electrical connections should be inspected.
c) Verification that intake and exhaust air flows are properly balanced.
d) Re-balancing as necessary.

CAUTION: ONLY QUALIFIED TECHNICIANS SHOULD SERVICE CONTROLS OR INTERNAL COMPONENTS.
