Installation

14.21 Air leakage check

• Is the main power wires properly inserted and fixated?

Check with the switchboard power turned off.

• Is the grounding wire properly connected?

Is the power cord properly grounded?

• Isn’t there any leakage in the coolant pipe?

Isn’t there any problem in the coolant circulation?

• You must check whether the air filter is properly

installed and whether it isn’t badly contaminated
with dust.
If the air filter is not properly installed, it cannot
filter the air flowing into indoors and can cause
problems to the air conditioner due to the
contamination.
