Final check and trial operation

To complete the installation, perform the following checks and tests to ensure that the air conditioner operates correctly.

Check the followings:

• Strength of the installation site

• Tightness of pipe connection to detect gas leak

• Electric wiring connection

• Heat-resistant insulation of the pipe

•Drainage

•Grounding conductor connection

•Correct operation (follow the steps below)

1.Press the Power button and check the following:

The indicator on the indoor unit lights up.

The airflow blade opens and the fan gears up for operation.

• Approximately 3~5 minutes later, outdoor unit will start to operate and the Cool or Warm air will blow out.

• After 12 minutes of stationary condition check the indoor unit air treatment:

Cooling mode (indoor unit check)  Inlet air temp. - Outlet air temp : From 10°K to 12°K ( indicative delta T)

Heating mode (indoor unit check)  Outlet air temp. - Inlet air temp : From 11°K to 14°K (indicative delta T) In heating mode, the indoor fan motor can remain off to avoid cold air blown into conditioned space.

3.Press the Air swing button and check the following:

 The airflow blades work properly.

4.Press the Power button to stop the operation.

• When you complete the installation successfully, hand over this manual to the user for storage in a handy and safe
