Pipe Installation-2; Installing Insulation; Filling With Putty; How To Operate Field Setting Buttons - Fujitsu WOYK150LJL Installation Manual

7. PIPE INSTALLATION-2

7.1. Installing insulation

• Use an insulation on the refrigerant pipes to prevent burn injury, condensation and
dripping.

7.2. Filling with putty

WARNING
Fill the piping holes and wiring holes with putty
(locally purchased) to avoid any gap (Fig A). If
small animals such as insects enter the external
unit, a short circuit may be caused near electrical
components in the service panel.
If the outdoor unit is installed at a level that is higher
than the indoor unit, the water that has condensed
in the 3-way valve of the outdoor unit could travel
to the indoor unit. Therefore, use putty in the space
between the pipe and the insulation to prevent the
entry of water to the indoor units.
