RECOVERY
NOTE:
When discharging refrigerant out of A/C system, always re-
cover it by using refrigerant recovery and recycling equip-
ment (1). Discharging it into atmosphere would cause
adverse effect to environments.
When handling recovery and recycling equipment, be sure
to follow the instruction manual for the equipment.
EVACUATING
EVACUATING PROCEDURE
1) Whenever opened (exposed to atmospheric air), air condition-
ing system must be evacuated by using a vacuum pump. The
A/C system should be attached with a manifold gauge set, and
should be evacuated for approx. 15 minutes.
NOTE:
Do not evacuate before recovering refrigerant in system.
2) Connect high charging hose (1) and low charging hose (2) of
manifold gauge set (3) respectively as follows:
High Charging Hose (1) High pressure charging valve (4)
on Receiver/dryer Outlet Pipe
Low Charging Hose (2) Low pressure charging valve (5)
on Suction Pipe
3) Attach center charging hose (6) of manifold gauge set (3) to
vacuum pump (7).
4) Operate vacuum pump (7), and then open discharge-side valve
(9) (Hi) of manifold gauge set (3).
If there is no blockage in the system, there will be an indication
on high pressure gauge (10).
When this occurs, open the other-side valve (8) (Lo) of the set.
5) Approx. 10 minutes later, low pressure gauge (11) should show
a vacuum lower than –760 mmHg providing no leakage exists.
NOTE:
If the system does not show a vacuum below –760
mmHg, close both valves, stop vacuum pump and watch
movement of low pressure gauge.
Increase in the gauge reading suggests existence of
leakage. In this case, repair the system before continu-
ing its evacuation.
If the gauge shows a stable reading (suggesting no leak-
age), continue evacuation.
6) Evacuation should be carried out for a total of at least 15 min-
utes.
7) Continue evacuation until low pressure gauge indicates a vacu-
um less than –760 mmHg, and then close both valves (8), (9).
8) Stop vacuum pump (7). Disconnect center charging hose (6) from
pump inlet. Now, the system is ready for charging refrigerant.
