Page 19: Air Purging Of The Piping And Indoor Unit
Air purging of the piping and indoor unit Required tools: Hexagonal wrench; adjustable wrench; torque wrenches, wrench to hold the joints and gas leak detector. Note: The air in the indoor unit and in the piping must be purged. If air remains in the refrigeration piping, it will affect the compressor, reduce the cooling capacity, and could lead to a malfunction of unit. -
Page 20: Pumping Down (Re-Installation)
Pumping down (Re-installation) Procedure 1. Confirm that both the 2-way and 3-way valves are set to the opened position. Remove the valve stem caps and confirm that the valve stems are in the opened position. Be sure to use a hexagonal wrench to operate the valve stems. 2. -
Page 21: Re-Air Purging (Re-Installation)
Re-air purging (Re-installation) Procedure: 1. Confirm that both the 2-way and 3-way valves are set to the closed position. 2. Connect the charge set and a charging cylinder to the service port of the 3-way valve. Leave the valve on the charging cylinder closed. 3. -
Page 22: Balance Refrigerant Of The 2-Way, 3-Way Valves
Balance refrigerant of the 2-way, 3-way valves Procedure: 1. Confirm that both the 2-way and 3-way valves are set to the open position. 2. Connect the charge set to the 3-way valve’s service port. Leave the valve on the charge set closed. Connect the charge hose with the push pin to the service port. -
Page 23: Evacuation
Evacuation Procedure: 1. Connect the vacuum pump to the charge set’s centre hose. 2. Evacuation for approximately one hour. Confirm that the gauge needle has moved toward -0.1 Mpa (-76 cmHg) [vacuum of 4 mmHg or less]. 3. Close the valve (Low side) on the charge set, turn off the vacuum pump, and confirm that the gauge needle does not move (approximately 5 minutes after turning off the vacuum pump). -
Page 24: Gas Charging
Gas charging Procedure: 1. Connect the charge hose to the charging cylinder. Connect the charge hose which you disconnected from the vacuum pump to the valve at the bottom of the cylinder. 2. Purge the air from the charge hose. Open the valve at the bottom of the cylinder and press the check valve on the charge set to purge the air (be careful of the liquid refrigerant). -
