Frequently Asked Questions - FlexFit 2U18MS2HDA HAIER

What is the operating temperature range of the Haier FlexFit 2U18MS2HDA air conditioner?

In cooling mode, the unit operates from 14 °F to 115 °F (-10 °C to 46 °C). In heating mode, it operates from -4 °F to 75 °F (-20 °C to 24 °C). Below -22 °F, the unit shuts down automatically.

What type of refrigerant does this system use?

This system uses R-410A, an environmentally friendly chlorine-free refrigerant. Do not use equipment designed for R22.

How do I register the warranty to get 10 years of coverage?

Register your product within 60 days of installation at haierductless.com/product-registration. Provide the model and serial numbers. The basic warranty is 5 years, but registration extends coverage to 10 years.

What should I do if the screen shows 'CC' on first power-up?

This is normal: the system performs a pre-programmed check. You can either let the test run (Cool or Heat mode at 25 °C), or bypass it by setting the mode to Dry (dehumidification) at 20 °C. The screen will show 'BP' then go to standby.

What are the essential safety precautions for installation?

Installation must be done by a licensed electrician. Turn off power before any intervention. Use a dedicated circuit and a ground fault circuit interrupter. Do not use an extension cord.

How do I maintain the air conditioner to ensure its longevity?

Clean the air filters regularly (every 1 to 3 months). Check the condensate drainage. Have the system inspected annually by an HVAC technician. In a salty environment, install a protective wall.

Which indoor units are compatible with the outdoor model 2U18MS2HDA?

This model can power up to two zones. Possible combinations include: two 7K units, 7K+9K, 9K+9K, 7K+12K, 9K+12K, or 12K+12K. See the compatibility table in the manual.

What is the maximum piping length between units?

Total piping length must not exceed 98 feet (29.9 m). If it exceeds 25 feet, add 0.2 oz of R-410A per additional foot. The minimum length per indoor unit is 10 feet.

How do I interpret error codes on the outdoor unit?

The outdoor unit's LED display shows codes like 'CH' (check in progress), 'EC' (wiring error), or 'PS' (test passed). Green lights indicate proper communication with indoor units.

Can I simply clean the filter with water?

Yes, remove the filter, wash it with warm soapy water, rinse and dry completely before reinstalling. Do not use solvents. A clogged filter reduces efficiency and may damage the unit.

OPERATING RANGE

The following information lists the operating range specific to each model.

2U18MS2HDA / 3U24MS2HDA / 4U36MS2HDA

Cooling: 14°F to 115°F

Heating: -4°F to 75°F

2U20EH2HDA / 3U24EH2HDA / 4U36EH2HDA / 5U42MS2HDA

Cooling: 14°F to 115°F

Heating: -15°F to 75°F

NOTES:

• The unit will stop running when outdoor temperature drops below -22^ (-30°C). The unit will resume operation automatically when the temperature rises above the low temperature limit.
• To achieve optimal capacity and efficiency at 5^(-15^) and below it is recommended to operate indoor fan in Turbo Mode.

- It is recommended to have a secondary heating source(s) available in case the temperature drops below the operating range.

PREPROGRAMMED SYSTEM CHECK

Please note system will NOT run normally unless one of the following procedures is completed.

When the system is first powered up, the indoor and outdoor LED display will display "CC". Please note that this is NOT an error code. This is an indicator that the system is ready to run the "Preprogrammed System Test".

The installer can choose one of the two following options:

- Option 1 (Preprogrammed System Test):

- Set the indoor mode to "Heat" or "Cool" and then set the indoor temperature to 77°F (25°C). The preprogrammed system test will start within five seconds.

- The indoor display will flash "Fn" and "N1"; the outdoor display will flash "N1".

- The test will continue to run for 18\~25 mins, including heating test (display "N2") and cooling test (display "N3") depending on outdoor conditions. For sequence of operation, refer to Installation Manual Section "Energy Star Models (Installation Capabilities)".

- Upon completion and passing of all tests, the indoor and outdoor display will show "PS". User can press any button to exit the test mode. The system can now be used normally.

- Option 2 (bypass “Preprogrammed System Test”): set the indoor mode to “Dry” mode first and then set the indoor temperature to 68°F (20°C).

• The indoor display will flash "BP" for five seconds and shut down automatically.
• The system can now be used normally.

Note: The automatic tests can also be by-passed by setting the indoor mode to dry and then setting the temperature to 68^ F ( 20^ C) while the unit is flashing CC after initial power has been applied to the unit. The indoor display should read BP for 5 seconds then go into stand-by mode. The unit can then be used normally. If installation test mode has been started, it will not be able to by-pass the test unless the power has been recycled prior to finishing the installation tests.

Note: If the outdoor temperature is exceeding normal operation range, (eg. below -4^ ( -20^ ) or above 115^(46^) ), running pre-programmable test may result in error code. Manufacturer suggests to by-pass the test during the severe weather and go back to the jobsite and run the test when outdoor temperature permits.

Note: If there is a need to run the pre-programmed installation tests again after successfully completing them initially, set the remote controller to cool, high fan speed, 60^ F ( 16^ C), and then press the sleep button 4 times continuously. After hearing 5 beeps on the indoor unit, power cycle.

Note: In order to achieve maximum performance at low ambient conditions it is recommend to set fan speed to turbo.

• All wiring should be rated for the amperage value listed on the rating plate. Use only copper wiring.
• All electrical work must be completed by a qualified electrician and completed in accordance with local and national building codes.
• Any servicing must be performed by a qualified individual.

For any service which requires entry into the refrigerant sealed system, Federal regulations require that the work is performed by a technician having a Class II or Universal certification.

• All air conditioners contain refrigerants, which under federal law must be removed prior to product disposal. If you are getting rid of an old product with refrigerants, check with the company handling disposal.
• These R-410A heat pumps systems require that contractors and technicians use tools, equipment and safety standards approved for use with this refrigerant. DO NOT use equipment certified for R22 refrigerant only.

WARNING

RISK OF ELECTRIC SHOCK. Could cause injury or death.

• An adequate ground is essential before connecting the power supply.
• Disconnect all connected electric power supplies before servicing.

- Repair or replace immediately all electrical wiring that has become frayed or otherwise damaged. Do not use wiring that shows cracks or abrasion damage along its length or at either end.

WARNING

RISK OF FIRE. Could cause injury or death.

- Do not store or use combustible materials, gasoline or other flammable vapors or liquids in the vicinity of this or any other appliance.

WARNING

This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance.

To avoid danger of suffocation, keep the plastic bag or thin film used as the packaging material away from young children.

Be sure not to allow foreign materials (oil, water, etc) entering the refrigerant piping. Seal the ends of refrigerant piping before storage.

For installation purposes, be sure to use the parts supplied by the manufacturer or other prescribed parts. The use of non-prescribed parts can cause serious accidents such as the unit falling, water leakage, electric shock, or fire.

The rated power supply of this product is 208/230 VAC/60hz/1PH. Verify the voltage is within 187\~253 range before turning the equipment on.

Supply power to the heat pump should be from a dedicated circuit that meets branch circuit ampacity requirements.

Use a special branch circuit breaker and receptacle matched to the power circuit capacity of the heat pump. (Install in accordance with local technical standard for electrical equipment.)

Do not extend the power cord.

Perform wiring work in accordance with standards so that the air conditioner can be operated safely and positively.

Install a leakage special branch circuit breaker in accordance with the related laws and regulations and electric company standards.

IMPORTANT SAFETY INFORMATION

CAUTION

It is highly recommended that you do not open or close the stop valves when the outdoor temperature is below -5°F (-21°C) as this may cause refrigerant leakage.

Make sure power is turned on for at least 12 hours after periods of being powered down in an 32^ F ( 0^ C) environment or lower.

Do not touch the fins of the coil. Touching the coil fins could result in damage to the fins or personal injury such as skin rupture.

Ensure the power circuit capacity is adequate for all loads connected to the electrical service panel. Increase the conductor and panel capacity if the total electrical loads exceed the power source capacity.

Contact the power utility if the power provided is below equipment rating plate requirements.

Be sure to install a breaker of the specified capacity.

Regulation of cables and breaker differs from each locality, refer in accordance with local rules.

Do not use existing refrigerant lines.

Use refrigerant tubing that is clean and free of any contamination which may cause damage to the system including sulfur, copper oxide, dust, metal chips, powder, oil or water.

Avoid brazing lines together. Use a continuous length of copper tubing as oxides formed during improper brazing techniques can damage the equipment.

Do not use copper pipes that have a collapsed, deformed, or discolored portion (especially on the interior surface). Otherwise, the expansion valve or capillary tube may become blocked with contaminants.

Improper line sizing will degrade performance. Peak pressure of R410A is much higher than R22. Use copper tubing with adequate wall thickness.

To prevent breaking of the pipe, avoid sharp bends. Bend the pipe with a radius of curvature of 4 in. (100 mm) or more.

If the pipe is bent repeatedly at the same place, it will break.

INSTALLATION INSTRUCTIONS

Step 1 - Preparation Cont.

NOTES:

• OD unit cannot hang from a ceiling or be stacked.
• Ensure that accumulated snow, debris, etc... will not block the air inlet or the coil exchanger if installing the OD unit with a fence or rail guard around it.
• Ensure ventilation in case of refrigerant leakage. R-410A is a safe, nontoxic, and nonflammable refrigerant.
• Avoid installing the OD unit where corrosive gases, such as sulfur oxides, ammonia, and sulfurous gas are produced. If unavoidable, consult with an installation specialist about using a corrosion-proof or anti-rust additive to protect the unit coils.
• Do not install the outdoor unit near the edge of a balcony. Otherwise, children may climb onto the outdoor unit and fall off of the balcony.
• Do not install the outdoor unit in the following areas: Areas heavily laden with oil or greasy vapors such as kitchens. Oils and grease will create sticky layer on the coil and also cause drainage problems, thus degrade unit performance.
• Corrosive areas that can potentially have combustible gas leaks, contain suspended fibers or flammable dust, or flammables such as paint thinner or gasoline can cause fires.
• Areas that contain small animals, rodents, reptiles or insects that can infiltrate the equipment and cause damage to internal components.
• Area where animals may urinate on the unit or ammonia may be generated.
• Install as necessary a protective fence or the like to prevent their access if the outdoor unit must be installed in an area within easy reach of the general public.
  • Take appropriate measures to protect it from those

elements If the outdoor unit is installed in a cold region that is affected by snow accumulation, snow fall, or freezing. To ensure a stable operating, install inlet and outlet ducts.

• Make sure the outdoor unit is installed level and is stable. Install snow protection hood as necessary.
• Avoid salty places such as the seaside for installation where air conditioner trouble is liable to occur.
• Install the outdoor unit in a location that is away from exhaust or the vent ports that discharge vapor, soot, dust, or debris.
• Install the unit where it will not be tilted by more than 3^ . However, do not install the unit with it tilted towards the side containing the compressor.
• When installing the outdoor unit where it may exposed to strong wind, fasten it securely.
• It is recommended that unit be installed under a canopy or elevated on a high stand.
• Protect the drain line from freezing in areas where temperature drops to 32^ (0^) or lower.
• Please set up the outdoor unit in a high place and please do not arrange the frame of installed stand under the drain port, because the water dropped from the drain port repeats freezing and accumulating, and may block the drain port.
• Do not use mineral oils on flared parts. Prevent mineral oil from entering the refrigerant system. Introduction of mineral oil may reduce the system life.
• Be sure to use an inert gas such as nitrogen while brazing any refrigerant lines to prevent any oxidation
• Be sure not to exceed refrigerant tubing length limits for different models to ensure smooth operation of the unit. Otherwise the equipment life cannot be guaranteed.

Step 2 - Installation of the Indoor Unit

A. Select the Indoor location:

• Do not expose the unit to unusual heat sources or steam outlets.
• Select a location where there are no obstacles in front of the unit.
• Make sure that condensate drainage can be conveniently routed away.
• Do not install near a doorway.
• Ensure that the space around the left and right of the unit is more than 4". The unit should be installed as high on the wall as possible but allow a minimum of 4" from the ceiling.
• Use a stud finder to locate and mark stud locations for mounting and to prevent unnecessary damage to the wall.
  • Install in a location that is strong enough to withstand the full weight and vibration of the unit.
• Leave enough space to allow access for routine maintenance.
• Select a location that gives easy access to removing and cleaning air filters.
  • Install in a location that is 3 ft. or more away from other electrical appliances, such as televisions and audio devices.

Step 2 - Installation of the Indoor Unit (Cont.)

B. Install the Mounting Plate

• Remove plastic bag, tape, and mounting plate from the back of the indoor unit.
• Place the mounting plate on the wall in the desired location taking into account the minimum clearances necessary for proper operation.
• Using a level, verify that the mounting plate is horizontal and mark the screw locations.
• Attach the mounting plate to the wall with the supplied screws.
• Wall anchors are supplied if not able to align all screw holes with studs.
• Be sure that the mounting plate has been attached firmly and that applied weight is evenly distributed by each screw. (At least one screw in wall stud, others can use wall anchors.)
• The piping for the indoor unit may be routed to and from the unit in one of several directions: left, left rear, right, right rear, or right below.

C. Install the Tubing

• Always use new clean copper tubing. Never reuse tubing if replacing an existing system.
• Measure and mark the location where the piping hole is to be drilled.
• Follow these steps to move the drain pipe if pipe location will be on the left side of the unit.
• Remove the stopper in the left drain hole and knockout the molded plug inside the port.
• Transfer the corrugate drain hose from the right side to the left side.
• Insert stopper into right side drain port. Using soap as a lubricant and a small screwdriver will allow for easier seating of the stopper.
• Drill the lineset hole using a 2 1/4" hole saw. Angle the drill with a downward pitch to the outside wall so that the outside wall hole will be at least a 1/4" lower than the inside hole. This allows for proper drainage of condensate.
• Install the lineset hole flange at the hole opening on the inside wall.

NOTE: The flange is prescored. It may be necessary to modify the flange to fit properly behind the wall unit housing.

D. Electrical Connections for the Indoor Unit

NOTE: Be certain all wiring complies with local building codes and NEC and that the supply voltage for this system is correct.

• Place the indoor unit on a solid work surface before making electrical connections.
• To make the electrical connections for the indoor unit, both the outer plastic and inner galvanized steel cover plate must be removed.
• Raise the front cover to access the screws for removing these covers.
• Route the 14/4 AWG stranded wiring through the slot in the back of the unit and into the front access panel.
• Using a wire stripper, remove the insulation and separate the 4 wires.
• Make wiring connections at each terminal according to wiring diagram. (Take note of the color of the wire at each terminal and ensure the wires are connected to the outdoor unit accordingly.)
• Ensure each wire is under the screw terminal plate and the plate is tightened.
• Ensure the 14/4 cable is secured under the strain relief bracket.
• Replace both cover plates and lower the front casing after the terminal block wiring is completed.

E. Leak Test

Perform the following steps for EACH line set. The primary service valve has a 5/16 port, an adapter may be necessary.

• Remove the cap on the service valve.
• Using a tank of dry nitrogen and approved regulator, charge the system with 150 psig of dry nitrogen using mini-split adapter to connect the valve.
• Check for leaks at the flare fittings using soap bubbles or another detection device. If a leak is detected, make repairs to the fittings and recheck. Proceed if no leaks are detected within 3 minutes.
• Using the same tank/regulator, charge the system to 300 psig.
• Check for leaks as earlier. Proceed if no leaks are detected within 3 minutes.
• Using the same tank/regulator, charge the system to 500 psig.
• Check for leaks as earlier. Keep system pressurized for at least 20 minutes.

WARNING

Do not use acetylene, oxygen or compressed air or mixtures containing air, oxygen, or combustible gases for pressure testing. Do not use mixtures of hydrogen containing refrigerant and air above

atmospheric pressure for pressure testing as they may become flammable and could result in an explosion. Refrigerant, when used as a trace gas, should only be mixed with dry nitrogen for pressurizing units. Failure to follow these recommendations could result in death or serious injury as well as equipment or property damage.

F. System Evacuation

NOTE- Do not open service valve.

• Remove the suction line cap and attach a micron gauge and vacuum pump. The port is 5/16", an adapter may be needed.
  • Evacuate the system to at least 350 microns.
• Close the vacuum pump valve and check the micron gauge. If the gauge rises above 150 microns in 60 seconds, the evacuation is incomplete or there is a leak in the system. If the gauge does not rise above 150 microns in 60 seconds, the evacuation is complete.
• Once evacuation is complete, remove the adapter and hose connection from the suction line port and replaced the cap.
