24 Kelvinator Air Conditioning Installation instructions
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 nished
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.
Operation test method
• Switch on power and press “ON/OFF” button on the
remote controller to start the operation. Press MODE
button to select the COOL, HEAT
(if applicable), FAN to check if all the functions work well.
• When the ambient temperature is lower than 16°C),
the unit can not be set on the remote control to work
in COOL mode. Please use the Emergency Operation
mode which is used only when the remote is unavailable
or in case of maintenance.

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.
