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.

• As shown in the figure below, it is easier to punch out

the knockout hole when the pipe cover is left in place

rather than when the cover is removed from the unit.

In knocking out the hole, the knockout section can

easily be removed by hand once the bottom of the

three locations where the section is joined along the

guide lines is broken using a screwdriver.

• After punching out the knockout hole, remove burrs

from the hole, and install the protective bush and

guard material around the passage hole provided as

accessories in order to protect the wires and pipes.

Also be sure to attach the pipe covers after connecting

the pipes. The pipe covers can be easily attached by

cutting off the slits at the lower part of the covers.

* Be sure to wear heavy work gloves while working.
