For Reference

If a heating operation is to be continuously performed for a long time under the condition that the outdoor temperature is

0°C or lower, draining defrosted water may be difficult due to the bottom plate freezing, resulting in trouble with the cabinet or fan.

It is recommended to procure an anti-freeze heater locally in order to safely install the air conditioner.

For details, contact the dealer.

•The indoor/outdoor connecting pipes can be connected in 4 directions.

Take off the knockout part of the pipe cover through which pipes or wires will pass through the base plate.

•Detach the pipe cover and tap on the knockout section a few times with the shank of a screwdriver. A knockout hole can easily be punched.

•After punching out the knockout hole, remove burrs from the hole and then install the supplied protective bush and guard material around the passage hole 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.
