REFRIGERANT CHARGING
This unit is designed with INTERLACED INDOOR HEAT EXCHANGER. Ensure that BOTH compressors
are running in order to optimise the performance of the unit before reading discharge pressure and liquid line
temperature. Then make the necessary refrigerant charge or Thermal Expansion Valve (TXV) adjustment
when required. If only ONE compressor is running, the subcool and superheat results will be different when
compared with TWO compressors running.
NOTE FOR SUBCOOL AND SUPERHEAT ADJUSTMENT
R410A refrigerant has POE oil that rapidly absorbs moisture.
The maximum time any system can be opened to atmosphere is 15 minutes.
CAUTION
IMPORTANT NOTES:
• Never allow R410A refrigerant to vent into the atmosphere. This is a serious offence in Australia & New
Zealand. Always reclaim refrigerant using equipment and container dedicated for R410A system use only.
• All work must be carried out in accordance with Australia and New Zealand refrigerant handling
code of practice.
• Only qualified technicians must perform any work related to addition or removal of refrigerant.
• R410A refrigerant must always be charged in liquid state. Always charge refrigerant in the unit liquid line.
The air conditioning system should always be liquid charged from the cylinder. When the system is in
a vacuum, always charge into the high pressure side. Although it is acceptable to charge refrigerant
into the discharge service port, but the liquid line service port on the shut-off valve is recommended.
• When the system is operating in cooling mode, it can be charge through the service port on the suction
line ball valve (larger of the two shut off valves). This ensures the liquid refrigerant goes into the
accumulator and then slowly enters the compressor.
• Remember, the pressure in this shut-off valve port will be high during heating mode, so the above
method is not possible. The system can be charged through the suction service port on the
compressor suction line. But be careful not to charge too much refrigerant at once, let the liquid enter in
short bursts by opening and closing your gauges.
• The units detailed on this guide are pre-charged with R410A refrigerant . Should there be need to add
or remove some refrigerant, it is recommended to follow one of the charging methods explained below.
• Where crankcase heaters are in operation, ensure to power up the unit for a minimum of 3 hours prior to
starting the compressor. For colder climates, a longer time period may be required.
