Cover knockout for pipe connection

Knockout procedure

•The indoor/outdoor connecting pipes can be connected to 4 directions. Take off the knockout part of the pipe cover in which pipes or wires pass through the base plate.

•As shown in the figure, do not remove the pipe cover from the cabinet so that the knockout hole can be easily punched.

To knock out, punch the 3 connected parts with a screwdriver and remove the pipe cover by hand.

•After marking the knockout hole, remove the burr and mount the attached protective bush and guard material for pass-through part in order to protect pipes and wires.

•After connecting the pipes, be sure to mount the pipe cover. The pipe cover is easily mounted by cutting off the slit at the lower part of the cover.

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 power supply cables can be inserted into the pipe holes. Enlarge the pipe holes if they are too small.

•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 the hot pipes.

To ensure good tensile strength, the electric cables must be fastened using the cable-holder on the plate.
