Charging the Refrigeration System

NOTICE

DAMAGE TO EQUIPMENT

Follow the procedures and tables outlined in this manual to charge the refrigerant if the piping exceeds the standard length.

Failure to follow these instructions can result in equipment damage.

Indoor and outdoor units are all provided with service valves. Connect the service valves to pipes for immediate system leak detection, vacuum pumping, and refrigerant filling procedures.

NOTE: Indoor units and outdoor unit model ACRMD4KI-3 are not pre-charged with refrigerant in the factory.

Leak Detection

Method One

1. Fill the service valve with nitrogen to increase pressure to 2.8 MPa (406 psi) and 4.15 MPa (601 psi) for refrigerant R410A.
2. Apply soapy water at the connecting joints or welding joints of pipes for leak detection.
3. Repair leak sources and maintain the pressure for more than six hours to ensure that the pressure is not decreased.
4. The low side of the compound gauge cannot be connected to the system.

Method Two

1. Fill with the refrigerant and stop when the pressure gauge indicates 0.3MPa (43 psi).
2. Fill with nitrogen and stop when the pressure gauge indicates 2.8 MPa (406 psi) and 4.15 MPa (601 psi) for refrigerant R410A.
3. Use an HFC electronic leak detector to detect the leak. Use the bubble gas leak testing method.

Vacuum Pumping

1. Exhaust the high pressure nitrogen in the system.
2. Connect the three flexible pipes of the compound pressure gauge to the corresponding joints of the service valve and the vacuum pump.
3. Start the vacuum pump and maintain the pressure inside the system below 650Pa (0.09 psi). Do not start the unit until the pipeline for vacuum pumping is turned off.

Calculating the Refrigerant Charge

When leaving the factory, the outdoor units that have been filled with refrigerant in the factory have enough refrigerant required to cover 5 m (49 ft) of pipe. If the actual length of the pipe exceeds 5 m (49 ft), add more refrigerant for the additional length. Outdoor unit model ACRMD4KI-3 needs to be charged with 1.65 kg (3.64 lb) of R410A refrigerant for the initial 5 m (49 ft).

Liquid Pipe Specifications – mm	R410A Refrigerant – g/m (lb/ft)	Actual Pipe Length
Ø22.23	350 (0.24)	L1
Ø19.05	260 (0.17)	L2
Ø15.88	180 (0.12)	L3
Ø12.7	120 (0.08)	L4
Ø9.52	70 (0.05)	L5
Ø6.35	45 (0.03)	L6

The refrigerant to be added is calculated on the basis of the length and thickness of the lengthened pipe. The formula is: refrigerant to be added (kg) = 0.35 × L1 + 0.26 × L2 + 0.18 × L3 + 0.12 × L4 + 0.07 × L5 + 0.045 × L6 .

If the calculated result is less than 0.1kg , round it to 0.1kg . For example, if the calculated result is 28.62kg , then add 28.7kg as the charge amount.

Charging the Refrigerant

1. Open the gas and liquid valves of the indoor and outdoor units.
2. If the filling tank for R410A does not have siphons, invert it.
3. Measure the filling amount with an electronic scale to prevent excessive filling.

Fill the gas pipe and the liquid pipe with liquid refrigerant at the same time. If the pressure is too large to fill the refrigerant, fill the refrigerant with a compressor during the test run.
