ENGLISH
- 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 difcult to
disconnect the service hose.)
- Fully open the valve stems of both 3- way valves using
a hexagon wrench. (After the valve stem begins to turn,
turn it with a torque of less than 2.9 N- m (30 kgf- cm)
until its stop turning.)
- Firmly tighten both 3- way valves blank cap and the
charging port cap.
ADDITIONAL CHARGE
- Refrigerant suitable for a piping length of 10 m. Is char-
ged in the indoor unit at the factory.
- When the piping is longer than 10 m., additional char-
ging is necessary. For the additional amount, see table
below:
4- OUTDOOR UNIT INSTALLATION
WARNING!
(1) When moving and installing the air conditioner,
do not mix gas other than the speci ed refrige-
rant (R-22) inside the refrigerant cycle.
(2) When adding refrigerant, add the refrigerant from
the charging port at the completion of work.
5- GAS LEAKAGE INSPECTION
WARNING!- After connecting the piping, check the
joints for gas leakage with gas leak detector.
6- POWER
(1) The rate voltage of this product is monophase
(230V/1Ph/50 Hz).
(2) Use a circuit breaker an receptacle matched to the
capacity of the room air conditioner.
(3) The circuit breaker is installed in the permanent wiring.
Always use circuit that can trip all the poles of the
wiring and has an isolation distance of at least 3 mm.
between the contacts of each pole.
(4) Perform wiring work in accordance with standards so
that the room air conditioner can be operated safely
and positively.
