(e) Tighten the O±ring fittings or the bolted type fittings to
the specified torque.
4. WHEN CONNECTING MANIFOLD GAUGE;
(a) Be sure to connect the charging hose end with a pin
to the compressor charging valve.
(b) The letter ºDº engraved near the compressor service
valve indicates the high pressure side, and ºSº indi-
cates the low pressure side. Pay careful attention
when connecting the hose.
(c) Tighten hose by hand.
(d) To prevent loosening of connected hose, do not apply
drops of compressor oil to the seat of connection.
HINT: After connecting the manifold gauge and the refrig±
erant container (service can), discharge any air in the
hoses.
5. WHEN EVACUATING;
Approx. 15 minutes after removal, check the system for
leaks, then take at least another 15 minutes to make sure
the air is fully removed.
6. WHEN HANDLING REFRIGERANT CONTAINER
(SERVICE CAN);
(a) Must never be heated.
(b) Must be kept below 4
°C (1 04°F).
(c) If warming service can with hot water, be careful that
the valve on top of the service can is never immersed
in the water, as the water may permeate into the refrig-
erant cycle.
(d) Empty service cans must never be re±used.
7. WHEN A/C IS ON AND REFRIGERANT GAS IS
BEING REPLENISHED;
(a) If there is not enough refrigerant gas in the refrigerant
cycle, oil lubrication becomes insufficient and com-
pressor burnout may occur, so take care to avoid this.
(b) If the valve on the high pressure side is opened, refrig-
erant flows in reverse and causes the service can to
rupture, so only open and close the vlave on the low
pressure side.
(c) If the service can is inverted and refrigerant is inserted
in a liquid state, the liquid is compressed and the com-
pressor brakes down, so the refrigerant must be in-
serted in a g¿¿seous state.
(d) Be careful not to insert too much refrigerant gas, as
this causes trouble such as inadequate cooling, poor
fuel economy, engine overheat, etc.
8. WHEN USING GAS±CYLINDER TYPE LEAK
DETECTION INSTRUMENT;
(a) As a naked flame is used, first make sure that there are
no flammable substances nearby before using it.
(b) Be careful, as poisonous gas is produced when
refrigerant gas comes in contact with heat parts.
