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 15 7.8 Evacuation Procedure: Connect the vacuum pump to the charge set’s centre hose. Evacuation for approximately one hour. Confirm that the gauge needle has moved toward -0.1 Mpa (-76 cmHg) [vacuum of 4 mmHg or less]. 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 16 7.9 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).
