How to remove the front panel

1.Remove screws of the front panel.

2.Pull the front panel downward.

Removing the front panel, the electric parts appear at the front side.

•The metal pipes are attachable to the piping holes. If the size of the used power pipe does not match with the hole, adjust the hole size to match with pipe size.

•Be sure to fix the power cable and indoor/outdoor connecting cable with bundling band sold on the market so that they do not make contact with the compressor and discharge pipe.

(Temperature of the compressor and discharge pipe becomes high.)

In order to avoid the force applied to on the connect- ing section, be sure to fix the cables to the cord clamps provided on the pipe valve fixing plate and the electric parts box.

*In case of flaring for R410A with the conventional flare tool, pull it out approx. 0.5 mm more than that of R22 to adjust to the specified flare size. The copper pipe gauge is useful for adjusting projection margin size.

2. Insert a flare nut into the pipe, and flare the pipe.

 

 

 

As the flaring sizes of R410A differ from those of

 

 

 

refrigerant R22, the flare tools newly manufactured

 

 

 

for R410A are recommended.
