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

. Electrical Installation
All electrical work must be carried out by a qualified and licensed technician. Make sure all wiring is in accordance with
local wiring rules. Wiring connections should be made in accordance with the wiring diagram provided.
DANGER
Live Electrical Supply !
During installation of your air conditioning unit, it may be necessary to work in close proximity to live electricity. Only
licensed electricians are allowed to perform these tasks.
Follow all electrical safety precautions when exposed to live electrical components.
CAUTION
Static Sensitive Electronic Devices !
• DO NOT handle electronic devices unless you are wearing an Anti-Static Wrist Strap that is connected to a GOOD
EARTH. Failure to protect the electronic devices from static electricity may cause unrepairable damage.
• Static damaged electronic devices are NOT COVERED for replacement under warranty.
Wiring Diagram
The wiring diagram specific for your air conditioning system is located on the inside panel of the control access door.
Always refer all wiring installation, servicing and troubleshooting of this equipment to this diagram to ensure correct
electrical connection are satisfied.
Supply and Power Requirements Procedure
It is the installer’s responsibility to provide power supply wiring to the mains supply terminal strip of the outdoor unit.
Make sure all wiring are in accordance with local wiring rules. Wiring should conform to all current electrical authority
regulations and all wiring connections to be as per electrical diagram provided with the unit.
• Confirm that the power supply available is compatible with the unit nameplate ratings. The supply power must be
within +10% to -6% of the rated voltage as per AS60038.
• Protect electrical service from over current and short circuit conditions in accordance with the latest edition of the
AS/NZS 3000 “Australian / New Zealand Wiring Rules”. Size protection devices according to the electrical data of the
unit and the table below.
• Installer to connect an appropriate load break (AC3) isolator in sub-mains wiring.
• Secure any power and control cables that enters in/exits out of the unit. Use the cable ties provided in the main
electrical panel.
Provide proper unit earth in accordance with local and national codes.
Main Voltage Balance Requirement
Check the voltage at the mains supply terminals to determine if it is balanced. Voltage imbalance on three phase systems
can cause motor overheating and premature failure. The maximum allowable imbalance is + 2.0%, should voltage
imbalance exceed this value, check unit wiring connections to locate and rectify faults or contact local supply authority.
