LEAK TEST, EVACUATION AND ADDITIONAL REFRIGERANT CHARGE
pressure in the system rises
water may lead to corrosion of parts in the refrigerant system
operating current rises
cooling (or heating) efficiency drops
moisture in the refrigerant circuit may freeze and block capillary tubing
Perform an air-tightness test for this package A/C. Check that there is no leakage from any of the connections.
Air and moisture in the refrigerant system may have undesirable effects as indicated below.
Therefore, the indoor unit and tubing between the indoor and outdoor unit must be leak tested and evacuated to
remove any noncondensables and moisture from the system.
Check that each tube (both liquid and gas tubes) between the
indoor and outdoor units has been properly connected and all
wiring for the test run has been completed. Remove the valve
caps from both the gas and liquid service valves on the outdoor
unit. Note that both liquid and gas tube service valves on the
outdoor unit are kept closed at this stage.
The refrigerant charge at the time of shipment is only guaranteed sufficient for a tubing length of up to 30* m.
The tubing may exceed this length, up to the maximum permitted length; however, an additional charge is
necessary for the amount that the tubing exceeds 30* m. (No additional refrigerating machine oil is needed.)
