5.2. Method for removing transportation stay
The yellow transportation stay installed over the compressor leg for
protecting the unit during transport must be removed. Proceed as
shown in figure 3 and described below.
1 Slightly loosen the fixing nut (B).
2 Remove the transportation stay (C) as shown in figure 3.
3 Tighten the fixing nut (B) again.
5.3. Method for installing drain piping
Depending on installation site, it may be required to install drain plug
for drainage (option kit).
In cold areas, do not use a drain hose with the outdoor unit.
Otherwise, drain water may freeze, impairing the heating
performance.
1 See figure below for installation of the drain plug.
2 Connect a field supplied vinyl hose (internal diameter of 25 mm)
to the drain socket (A).
If the hose is too long and hangs down, fix it carefully to prevent
kinks.
