CHECK THE DRAINAGE

•

Open front panel and remove air filters.
(Drainage checking can be carried out without removing the
front grille.)

•

Pour a glass of water into the drain tray-styrofoam.

•

Ensure that water flows out from drain hose of the indoor
unit.

EVALUATION OF THE PERFORMANCE

•

Operate the unit at cooling operation mode for fifteen
minutes or more.

•

Measure the temperature of the intake and discharge air.

•

Ensure the difference between the intake temperature and
the discharge is more than 8°C.

NOTE

These equipment shall be connected to a suitable mains network
with a main impedence less than the following:
CS-C125KE / CU-C125KE: 0.31

Ω

CHECK ITEMS

Is there any gas leakage at flare nut connections?

Has the heat insulation been carried out at flare nut
connection?

Is the indoor/outdoor connecting cable being fixed to terminal
board firmly?
Is the connecting cable being clamped firmly?

Is the drainage OK?
(Refer to “Check the drainage” section)

Is the earth wire connection properly done?

Is the indoor unit properly hooked to the installation plate?

Is the power supply voltage complied with rated value?

Is there any abnormal sound?

Is the cooling operation normal?

Is the thermostat operation normal?

Is the remote control’s LCD operation normal?

Is the air purifying filter installed?
