Testing The Air Conditioner - Kelvinator KSV25CRF Installation Manual

Testing the air conditioner

Soapy water method
Apply soapy water or liquid neutral detergent on all valves and
pipe connections (A, B, C and D, refer to the figure below) involved
in installation by a soft brush to check for leakage. If bubbles come
out, the pipes have leakage.

Leak detector
Use the leak detector to check for leakage.
Electrical safety check
Perform the electric safety check after completing the installation:
1. Earthing work
After finishing earthing work, measure the earthing
resistance by visual detection and earthing
resistance tester.
2. Electrical leakage check (perform while the test is running)
During test operation after finishing the installation, the service
person can use the electric probe and multimeter to perform
the electrical leakage check. Turn off the unit immediately if
refrigerant leakage happens. Check and find out the solution
ways until the unit operates properly.
Operation test
1. Before operation test
• Do not switch on power before installation is finished
completely.
• Electric wiring must be connected correctly and securely.
• Stop valves of the connection pipes should be
fully opened.
• All the impurities such as scraps and waste must be
cleared from the unit.

Pump down
When relocating or disposing of the air conditioner, pump down
the system following the procedure below so that no refrigerant is
released into the atmosphere.
• Connect the hose of manifold valve to the charge port of stop
valve on the gas pipe side of the outdoor unit.
• Close the stop valve on the gas pipe side almost completely.
• Fully close the stop valve on the liquid pipe side.
• Turn on the unit in COOL mode.
• Fully close the stop valve on the gas pipe side when the
pressure gauge shows 1 - 0.5 kgf/cm (100 ~ 50 kPa).
• Stop the test run operation by turning the unit off and
all the refrigerant gases have been collected in the
outdoor unit.
