3. CHECKING THE PIPE CONNECTIONS FOR
GAS LEAKING
- For both the indoor and outdoor unit sides, check the
joints for gas leaking by the use of a gas leakage detec-
tor without fail when the pipes are connected.
4. HEAT INSULATION ON THE PIPE JOINTS
- Put coupler heat insulator on the joints.
AIR PURGE
- Close the high pressure side valve fully.
- Check if the piping connections are secure.
- Check that the stems of both 3- way valves are closed
fully.
- Connect the gauge manifold service hose to the char-
ging port of the 3- way valve (side with the projection of
pushing in the valve core).
- Open the low pressure side valve of the gauge mani-
fold fully.
- Operate the vacuum pump and start pump down.
- Pump down the system for at least 15 minutes, then
check if the compound pressure gauge reads - 100kPa
(- 76 cm Hg, -1bar)
- At the end of pump down, close the low pressure side
gauge of the gauge manifold fully and stop the vacuum
pump.
- Slowly loosen the valve stem of the 3- way valve. When
the compound pressure gauge reading reaches 1- 2
kg/ cm2, retighten the valve stem and disconnect the
service hose from the 3- way valve charging port.
(If the stem of the 3- way valve is opened fully before
the service hose is disconnected, it may be difficult to
disconnect the service hose.)
