ENGLISH
Evaluation of the performance
Operate the unit for 15~20 minutes, then
check the system refrigerant charge:
1
Measure the pressure of the gas side
service valve.
2
Measure the air temperature from inlet and
outlet of air conditioner.
3
Ensure the difference between the inlet
and outlet temperature is more than 8 °C.
4
For reference; the gas side pressure at
optimum condition is shown on table
(cooling)
The air conditioner is now ready to use.
* The feature can be changed according a
type of model.

Do not make drain piping like the
following.

Drain test
Use the following procedure to test the drain
pump operation:
- Set the air direction louvers up - and - down
to the position(horizontally) by hand.
- Pour a glass of water on the evaporator
using a kettle.
- Ensure the water flows through the drain
hose of the indoor unit without any leakage
and goes out the drain exit.
[Ceiling suspended type]
- Drain piping must have down-slope (1/50 to
1/100): be sure not to provide up - and -
down slope to prevent reversal flow.
- During drain piping connection, be careful
not to exert extra force on the drain port on
the indoor unit.
- Remove the rubber stopple before
connecting drain hose.
- Hook on the bracket after connecting the
drain hose as below.
