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.
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. Refer recovered refrigerant and
acceptable refrigerant quality to 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.
Use only cleaning solvents that do not have ozone depletion factors. Properly dispose of used cleaning materials.
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 have 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 minimise
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 26kW 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.
• Refer connection and location of condensate drain in the unit drawing 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.

• Firmly tighten the set bolts back the compressors onto
the unit. Recommended torque is 131 Nm. Its is critically
important for the grommet not to be compressed.
• Check to make sure that there are no damage to the
piping systems.

• Braze refrigeration piping. Refer to piping sections
for details of field pipe sizes and piping installation
procedure.
10. Field Pipe Connection
CAUTION
The units described in this guide uses R-410A refrigerant
This operates at a pressure approximately 1.6 times higher than a similar systems using R-22. 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 persons 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.

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 swagged 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.
