Snow
In regions with snowfall, snow might build up and freeze between the
heat exchanger and the casing of the unit. This might decrease the
operating efficiency. To prevent this:
1 Remove the beam structure (see figure below).

3 Remove the burrs, and paint the edges and areas around the
edges using repair paint to prevent rusting.
NOTICE
Precautions when making knockout holes:
▪ Avoid damaging the casing and underlying piping.
▪ After making the knockout holes, we recommend to
remove the burrs and paint the edges and areas
around the edges using repair paint to prevent rusting.
▪ When passing electrical wiring through the knockout
holes, wrap the wiring with protective tape to prevent
damage.
INFORMATION
We suggest to install the optional bottom plate heater
(EKBPH140N7) when the unit is installed in cold climates.

To prevent the outdoor unit from falling
over
In case the unit is installed in places where strong wind can tilt the
unit, take following measure:
1 Prepare 2 cables as indicated in the following illustration (field
supply).
2 Place the 2 cables over the outdoor unit.
3 Insert a rubber sheet between the cables and the outdoor unit
to prevent the cables from scratching the paint (field supply).
4 Attach the ends of the cables and tighten them.
