Installation and Commissioning Guide

Split Ducted Outdoor Units

DANGER

Hazardous Voltage - Risk of Electrocution.

Turn Off the power from main isolator before proceeding with any service work of the unit. Observe proper LOCK-OUT/TAG-OUT (LOTO) procedures for electrical appliances in order to prevent accidental switching-on of the power supply. Extreme care and caution must be observed should there be a need to work on live circuit.

WARNING

EC Motors are fitted with high power capacitors and can have dangerous residual voltages at motor terminals after power has been isolated. Wait at least 5 minutes after power isolation and test for any residual voltage before beginning service work.

CAUTION

Beware of Rotating Fans!

Ensure that indoor and outdoor fans are isolated and have come to a complete stand still before servicing the equipment. Beware of pinch point and sharp edges which can cause cutting injury. Secure the fans against accidental contact. Always wear appropriate PPE and remove any dangling jewellery and protect long hair by wearing a cap. Ensure that no loose clothing can be caught / entangled in moving parts.

VISUAL INSPECTION AND WORK ASSESSMENT

Work areas and conditions must first be assessed and evaluated for any potential hazardous conditions. It is also important to be familiar with the unit parts and components before proceeding with any service task.

04. Installation Information

All service technicians handling refrigerant must be licensed to handle refrigerant gases.

Recover and Recycle Refrigerants

Never release refrigerant to the atmosphere! It is an offence in Australia to do so. Always recover, recycle and reuse refrigerants. When removing from the system, properly contain and identify refrigerants in its dedicated container for proper disposal and/or storage. Always consider the recycle or reclaim requirements of the refrigerant before beginning the recovery procedures. Obtain a chemical analysis of the refrigerant if necessary. For the recovered refrigerant and acceptable refrigerant quality refer to the existing standards and regulations.

Refrigerant Handling and Safety

Consult the refrigerant manufacturer's safety data sheet (SDS) for information on proper handling and to fully understand health, safety, storage and disposal requirements. Use the approved containment vessels and refer to appropriate safety standards. Comply with all applicable transportation standards when shipping refrigerant containers.

Service Equipment and Recovery Procedures

Always use refrigerant reclaiming equipment in order to minimise refrigerant emissions. Use equipment and methods which will pull the lowest possible system vacuum while recovering and condensing refrigerant. Equipment capable of pulling a vacuum of less than 500 microns is required.

Do not open the system to the atmosphere for service work until refrigerant is fully removed and/or recovered. Perform refrigeration system evacuation, prior to charging, in accordance with AIRAH / IRHACE Refrigerant handling code of practice.

Let the unit stand for 1 hour and with the vacuum not rising above 500 microns. A rise above 500 microns indicates a leak from the system and a leak test is required to locate and repair any leak.

CAUTION

A leak test is always required on any repaired section of the refrigeration system.

Charge refrigerant into the system only after the equipment does not leak or contain moisture. Ensure that R-410A is only charged in liquid form. Take into consideration the correct amount of refrigerant charge specified for the system to ensure efficient unit operations. When charging is complete, reclaim refrigerant from charging lines into an approved refrigerant container. Seal all used refrigerant containers with approved closure devices to prevent unused refrigerant from escaping to the atmosphere. Take extra care to maintain all service equipment directly supporting refrigerant service work such as gauges, hoses, vacuum pumps and recycling equipment.

INSTALLATION PREPARATION (Pre-Installation considerations)

The following items must be considered before beginning the unit installation:

• Verify the unit capacities and ratings with the unit nameplate
• Make certain the floor or foundation is level, solid and has sufficient structural strength to support the unit and accessories weight.
• Install anti-vibration rubber (installer to supply) under all of the unit's feet to help reduce noise and minimize vibration transfer through the foundation. Ensure that all anti-vibration rubbers are rated to provide stable support without impairing the unit's structural integrity.
• Diameter or width of anti-vibration rubber's must be at least equal to the width of the actual feet to prevent deformation overtime.
• Preferably use anti-vibration rubber pads on residential units (up to 23kW split ducted).
• Allow minimum recommended clearances for periodic maintenance and service access.
• Allow sufficient space above the unit for the outdoor air discharge. Condenser air inlet, located on the coil side of the unit, requires sufficient airflow clearance for the optimum unit performance.
  • Note the conditioned supply air and return air location. Ensure sufficient spaces are allocated for these purposes.
• For the connection and location of condensate drain in the unit, refer to the drawings and dimensions section of this manual.
• Wiring connections must be in accordance with the wiring diagram provided with the unit.
  • Make sure all wirings are in accordance with local electricity authority regulations and standards.
• Do not install the unit close to an area where there is a danger of fire due to volatile, explosive, flammable and/or hazardous materials.
• Ensure that spaces around the unit are free from any obstructions for optimum unit performance.
• Installer to ensure correct size/type that main circuit breaker and cable is installed in unit sub-mains to protect the sub-mains and unit wiring.
• Installer to ensure correctly rated residual current device (RCD) is installed as per AS/NZS 3000:2018 (also known as Australian Wiring Rules).
• Secure the power cords and control cables that goes in/out the unit. Use the cable ties provided in the control box.

11.01. Piping and Brazing

CAUTION

The units described in this guide use R-410A refrigerant

R-410A operates at a pressure approximately 1.6 times higher than similar systems using R22. When installing equipment using R-410A refrigerant, there are number of standards that must be met:

• The system of this unit operates with Polyolester (POE) oil that rapidly absorbs moisture.
• The maximum time any system can be opened to atmosphere is 15 minutes.
• It is important to work with absolute cleanliness.
• Brazing must be done with the use of Nitrogen to avoid carbon deposits into the pipes.
• The system must be evacuated thoroughly to 500 microns (see evacuation procedure).
• The system must always be charged with R-410A refrigerant in liquid state.
• Never allow R-410A refrigerant to vent into the atmosphere. It is an offence to release refrigerant in Australia.
  • Always reclaim refrigerant using equipment and container dedicated for R-410A system use only.
• Only qualified technicians are allowed to perform any work described in this guide.
• All work must be carried out in accordance with Australia and New Zealand refrigerant handling code of practice.

Maximum allowable total equivalent field pipe length is 60 metres, see diagram below. This includes all the equivalent pipe fitting loses and vertical height difference. Vertical height difference must not exceed 20 metres. Table 1 below shows the equivalent straight pipe length of elbow fittings.

TABLE 1: EQUIVALENT STRAIGHT PIPE LENGTH OF ELBOW FITTINGS (METRES)
Pipe size Nominal Diameter	90° Long Radius Elbow	90° Short Radius Elbow	45° Long Radius Elbow	45° Short Radius Elbow

25.4 (1")	0.52 0.78 0.24	0.36
28.58 (1-1/8")	0.55 0.83 0.27	0.41

Selected field pipe sizes must match the recommended sizes in table above. If the installation requires different field pipe diameter due to different application condition other than recommended, contact ActronAir for advice.

Most of unit pipe connections are factory swaged to easily fit to the recommended field pipe diameter.

When it is required to install other refrigeration devices, such as refrigerant drier, solenoid valve and the like, include the equivalent straight pipe length of the device in the calculation of total equivalent field pipe length.

Both pipes are required to be insulated.

NOTES

(1) Included in maximum field pipe length.

(2) For pipe runs 0-20m 3/8" must be used.

(3) Cut Swaged End in the field to fit field pipe.

CAUTION

Brazed joints should only be made while purging Nitrogen through the system.

Failure to do so will cause carbon deposit to be left on the internal pipe surface, that in turn can cause system failure and void of warranty.

Installing interconnecting pipe work to indoor, nitrogen bleed procedure (First fit or rough in stage only)

1. Run interconnecting pipe work from condenser location to evaporator.
2. Release pressure in evaporator and remove caps.
3. Fit copper tube into tail, set nitro bottle and regulator up at condenser end of pipe work.
4. Fit nitrogen line into liquid line with rubber bung to seal the connection. The seal will prevent air being sucked into pipe work.
5. Leave suction line open, set nitro regulator for nitrogen to flow through pipe work at 2 l/s flow rate @20kPa.
6. Braze required joints as quick as possible. See Diagram Above.

Installing interconnecting pipe work to outdoor, nitrogen bleed procedure (First fit or rough in stage only)

1. Starting with circuit 1 system, remove piping caps from the condenser and fit pipe work into tails.
2. Fit nitro hose onto suction ball valve and fit open hose onto liquid line post valve.
3. Set nitrogen regulator to 2 l/s flow rate through pipe work and evaporator.
4. Braze remaining joints as quick as possible.
5. Allow the brazed joints to cool and conduct leak test in the connections.

11.02. Pressure Testing

Pressurize the system to 2500kPa in stages. A recommended pressure test is to be performed for no less than 1 hour at 2500kPa.

IMPORTANT

Importance of Evacuation:

• Any non-condensable product left in the system can cause the pressure in the high side of the system to increase and in turn, the compression temperature to rise.
• Moisture will result in adverse reaction in the refrigerant circuit.
• The POE oil used in the R-410A compressor is hygroscopic, which means that it absorbs moisture from the air. To prevent chemical reactions in the system, any moisture must be removed at all costs.
• Oxygen (air) reacts with the compressor oil and can lead to faults such as compressor failure.

See Diagram Below:

11.03. Evacuation Procedure (Triple Evacuation)

1. Fit service gauges to the ball valves (liquid line service valve and suction line service valve).
2. Evacuate the system to 1000 microns.
3. Check vacuum with vacu stat. Break the vacuum with dry Nitrogen to 100kPa
4. Release Nitrogen pressure. Evacuate to 500 microns.
5. Check vacuum with vacu stat. Break the vacuum with dry Nitrogen to 100kPa
6. Release Nitrogen pressure. Evacuate to 500 microns.
7. Check vacuum with vacu stat.
8. Open valve.

19. Refrigerant Charging

• The units detailed on this guide are pre-charged with R-410A refrigerant. Should there be a need to add or remove some refrigerant, it is recommended to follow the charging method explained below.
• Never allow R-410A refrigerant to vent into the atmosphere. It is an offence to release refrigerant in Australia. Always reclaim refrigerant using equipment and container dedicated for R-410A system use only.
• All work must be carried out in accordance with Australia and New Zealand refrigerant handling code of practice.
• Only qualified personnel are allowed to perform any work described in this guide and specifically work related to addition or removal of refrigerant.
• R-410A refrigerant must always be charged in liquid state.
• Only during the compressor running condition the system can be charged through the suction service port on the compressor suction line.
  • Changes in refrigerant charge must be noted to a label that is fixed to the unit for future reference.

CAUTION

R-410A refrigerant has POE oil that rapidly absorbs moisture. The maximum time any system can be opened to atmosphere is 15 minutes.

19.01. Charging Method: Sub-cooling and Superheat

LLT = Liquid Line Temperature

SLT = Suction Line Temperature

SCT = Saturated Condensing Temperature

SST = Saturated Suction Temperature

19.01.02. Cooling and Heating Operation:

Adjust the refrigerant charge to obtain the correct super heat and sub-cool for optimal performance as follows:

1. Ensure that air filters are fitted and total system airflows are achieved. (Air filters are not supplied with the unit, it is the responsibility of the installing contractor to provide and fit adequate return air and fresh air filters).
2. Connect service gauges to the schrader valves.
3. Start the unit in cool mode ensuring that the compressor is in operation before taking service gauges reading. Allow the system to stabilise for next 15 - 30 minutes before recording.
4. Record the discharge pressure, suction pressure, liquid line temperature and suction line temperature for all the refrigeration circuits.

Discharge Pressure = ____ kPa Suction Pressure = ____ kPa

Liquid Line Temperature (LLT) = ____°C Suction Line Temperature (SLT) = ____°C

NOTES

• Accurate pressure and temperature measuring tools should be used to achieve satisfactory results.
• The sensors of thermocouple must be in good contact with the area being measured and must be insulated in order to obtain correct reading.

See Diagram Below:

19.01.03. Checking For Sub-cooling

1. From the R-410A Pressure / Temperature Chart record the corresponding Saturated Condensing Temperature (SCT) at the given discharge pressure.
2. Calculate the system sub-cooling using the formula below:

Sub-cooling = SCT - LLT

1. If sub-cooling is within the range (see charging table below), there is no need to add/remove refrigerant.
2. If sub-cooling is lower than minimum, the system is undercharged, it is necessary to add refrigerant.
3. If sub-cooling is higher than maximum, the system is overcharged, it is necessary to remove refrigerant.

Allow the systems to stabilise (15 - 30 mins) and repeat the steps 1-3 until sub-cooling falls within the range specified in the table below.

19.01.04. Checking for Superheat:

Maintaining the correct superheat is important for ensuring the evaporator is achieving maximum capacity and avoiding excessive liquid refrigerant returning to the compressor.

1. From the R-410A Pressure/Temperature Chart record the corresponding Saturated Suction Temperature (SST) at the given suction pressure.
2. Calculate the system super heat using the formula below:

Superheat = SLT -SST

1. If superheat is within the range (see charging table below), there is no need to add/remove refrigerant.

2. If superheat is lower than minimum, it means that liquid refrigerant may be returning to compressor. It is necessary to remove refrigerant or check EEV settings.

3. If superheat is higher than maximum, it means that refrigeration capability of evaporator is not fully maximised. It is necessary to add refrigerant charge or check EEV settings.

Allow the systems to stabilise (15 - 30 mins) and repeat the steps 1-3 until superheat falls within the range specified in the table below.

Cooling Heating
Sub-Cool Superheat Sub-Cool Superheat
4 - 8 2 - 8 10	14 2 - 8

NOTES

The above sub-cool and superheat recommendations are based on the following rated conditions:
• Cooling: 35 °C DB outdoor, air entering indoor at 27°C DB / 19°C WB.
- Heating: 7 °C DB / 6°C WB outdoor, air entering indoor at 20°C DB Nominal indoor airflow.

20. Maintenance

Maintenance Procedures

This section describes the procedures that must be performed as a part of normal maintenance program. Regular servicing of equipment by licensed technician is highly recommended. Regular servicing of your unit helps in maintaining its optimum performance and reliability. The checklist and service periods provided on this manual are guides only, as some sites may require more frequent servicing. Always disconnect electrical power to the unit before performing these procedures. It is always a safe practice to observe all safety warnings and cautions when conducting maintenance tasks.

DANGER

Live Electrical Connections!

It may be necessary to work with live electrical components on certain maintenance tasks. Only licensed electricians and qualified technicians are allowed to perform these tasks.

Beware of Rotating Fan Blades!

Always make sure that all power supply, to the Outdoor Fans are turn Off and isolated.

Observe WH&S safety procedures, do not wear loose clothing and any jewellery when working near the fans. Wear PPE whenever performing any maintenance procedures.

Observe all necessary procedures when working on a confined space.

WARNING

Hazardous Voltage!

Always make sure that all power supply, including remote controls, are disconnected before performing maintenance. Observe proper LOCK-OUT/TAG-OUT procedures to ensure that power cannot be inadvertently energised. Failure to disconnect power before maintenance procedures can result in serious injury and/or death. EC Motors are fitted with high power capacitors and can have dangerous residual voltages at motor terminals after power has been isolated. Wait at least 5 minutes after power isolation and test for any residual voltage before beginning service work.

Annual Maintenance Checklists

• Perform general maintenance inspections.
  • Perform scheduled start-up checks.
• Leak test refrigerant circuits.
• Inspect contacts of all contactors and relays. Replace all worn contacts as required.
• Inspect, clean and tighten all electrical connections.
• Inspect the air filters, clean or replace as required.
• Clean and repaint any corroded panel section.
• Ensure no blockage of airflow through variable speed drive.

- Check fans for balanced operation. Make sure that there are no loose screws / bolts, no fan blades interference and no damage to the fans and guards.

Cleaning the Condenser Coils

Clean the coils at least once a year or more frequently if unit is located in a dusty and dirty environment, in order to maintain your system's proper operating performance. High discharge pressures are good indication that the coils need cleaning. When using detergent or solvents to clean the coils, follow the manufacturer's instructions to avoid potential damage to the coils and to the unit.

To clean the refrigerant coils, use a soft brush and water spray, such as garden hose or pressure washer with low pressure nozzle.

WARNING

Do Not Use High Alkaline Detergent!

When using detergent for coil cleaning, ensure that the alkaline level is no higher than 8.5, which can cause corrosion damage to the coils.

No Water into the Electrical Compartments!

Ensure consideration is given to the possibility of water entering the electrical compartments during cleaning of the condenser coil.

Coil Cleaning Procedures

• Disconnect power to the unit.
• Remove the louvered panels from the unit to gain access to the air inlet side of the coils.
• Use a soft brush to remove loose dirt and debris from both sides of the coils.
• Straighten bent coil fins with fin comb.
• Prepare the detergent solutions according to the manufacturer's instructions.
• Spray solution at a 90^ angle to the coils, keeping a minimum nozzle spray angle of 15^ , with at least a 1800mm distance from the coils and 600 psi pressure.
• Spray leaving air side of the coils first then the air inlet side. Allow the solution to stand on the coils for five minutes.
• Rinse both sides of the coils with cool clean water.
• Inspect the coils, if they are still dirty, repeat the cleaning procedure.
• Clean and wipe dry the outer and inner sides of the unit, the refrigerating parts and other components.
• Ensure that the condensate drain lines are not blocked.
• Reinstall all unit panels, covers and guards.
• Restore electrical power to the unit.

Troubleshooting Guide

Fault Possible	Causes Remedies
The system does not start.	Built-in safety timers have been activated Ensure that 5 minutes has passed from turn on time.
	A breaker has turned Off or a fuse has blown. Check breakers and fuses.
	The master wall control setpoint is incorrect. Check master wall control settings are correct. Check the thermostat setpoint is set low enough for cooling or high enough for heating.
	The master wall controller timer setting is incorrect.	Check the master wall controller timer settings. See Operation Manual section.
Air does not flow (Indoor unit)	Zones might be switched off. Check zones are switched on..
	During heating operation, the hot start function may have been activated.	During heating operation the indoor fan is delayed for 46 seconds or until the indoor coil reaches 24°C (whichever occurs first). This is to prevent cold drafts. Wait 46 seconds and the air will start flowing.
	During defrost of the outdoor coil in heating operation; the indoor fan will not operate for several minutes. (HEAT LED flashes on master wall control).	This is normal operation during the defrost cycle to prevent cold air being blown into rooms.
Cooling/Heating is not sufficient.	The cooling/heating function may not work effectively when the return air filter is clogged with dust and dirt.	Clean the return air filter.
	The cooling/heating function may not work effectively if the air inlet and air outlet on the outdoor unit are blocked.	Make sure the air inlet and air outlet on the outdoor unit is not blocked. Check that the area around the outdoor unit is free from obstructions that may cause the airflow to recirculate.
	The airflow across the indoor coil may not be enough and the anti-freeze protection or over heat prevention systems can lower the cycle capacity for the unit.	Reduce the total static pressure on the indoor fan to increase airflow. For example increase duct sizes, reduce tight duct work bends or increase return air grille size.
	The cool/heat load is too great for the air conditioner.	Perform a heat load analysis on the conditioned space. You may need to consider upgrading your air conditioner with a larger system.
	Open windows or doors will cause inefficient operation.	Close windows and doors in conditioned areas.
	Appropriate zones not turned on. Turn on appropriate zones (if applicable)
	The outside temperature is beyond the air conditioner design conditions.	If you know a extreme day is coming turn the air conditioner on a few hours before ambient temperatures reach extreme. This should help on those few extreme days.
Steam emitted from outdoor unit.	This is caused by the defrosting operation of the outdoor units heat exchanger in heating operation in cold ambient conditions.	This is normal during the defrost operation in cold ambient conditions.
Water emitted from outdoor unit.	Condensation of water on the outdoor coil during heating operation.	This is normal during heating operation. You can purchase drip trays to contain then drain this excess water.

Installation and Commissioning Guide

Split Ducted Outdoor Units

Fault Possible	Causes Remedies
Set temperature cannot be adjusted.	The master control set temperature limits are reached.	Check the upper and lower temperature limits are set correctly. See operation manual for details on setting upper and lower temperature limits.
Occasional wishing noise can be heard on heating cycle.	This is the sound of the gas changing directions as de-ice cycle begins.	This is a normal function of an air conditioner. The unit is removing any ice on the outdoor unit.
The compressor is running but the system is not cooling.	You are in heating mode. Check the temperature settings.
	The reversing valve has jammed between heating and cooling.	Replace reversing valve.
The outdoor coil keeps freezing over.	Outdoor coil sensor might be faulty. See sensor (temperature/resistance) table and check resistance value.	Replace faulty sensor.
	May have obstruction in outdoor coil. Remove obstructions.
There is only one condenser fan working.	The fan is faulty. Test the fan motor for correct voltage, check the motor winding resistance, open circuit, check capacitor, etc.	Replace faulty fan. If the fan motor needs to be replaced and there isn't one available immediately, then just disconnect the fan electrically and cover the faulty motors fan guard. This way the unit can still operate at reduced capacity using 1 fan until you get a replacement fan motor.
The indoor unit gives out odour.	This happens when smell of the room, furniture, or cigarettes are absorbed into the unit and discharged with the airflow.	If this happens, we recommend you to run the air conditioner on cooling for a period of time with the doors and windows open or have the indoor unit washed by a technician. Consult the installer from whom you bought the air conditioner.
	Check the drain is not piped into the sewerage drain line.	Re-pipe drain with a P-Trap and connect into household drainage or storm water drain.
