Snow

In regions with snowfall, snow might build up and freeze between the
heat  exchanger  and  the  external  plate.  This  might  decrease  the
operating efficiency. To prevent this:

1

Remove  the  knockout  hole  (a)  by  tapping  on  the  attachment
points with a flat head screwdriver and a hammer.

a

2

Remove  the  burrs,  and  paint  the  edges  and  areas  around  the
edges using repair paint to prevent rusting.

4.1.4

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.
