REFRIGERANT PIPING
Knockout of Pipe Cover
Knockout procedure
• The hydro/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.
• Detach the piping cover and give an impact on the
knockout section a few times with the shank of a
screwdriver. A knockout hole can easily be punched.
• After punching the knockout hole, remove burrs of
the hole and then install the supplied protective bush
and guard material for passage part to protect wires
and pipes.
Be sure to attach the pipe covers after pipes have
been connected. Cut the slits under the pipe covers
to facilitate the installation.
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 pipe cover.
* Be sure to wear heavy work gloves while working.
