Drain work. (Heat Pump Unit Only)
1. Use drain elbow for drainage.
2. If the drain port is covered by a mounting base or fl oorsurface,
place additional foot bases of at least 1-3/16"(30mm) in height
under the outdoor unit's feet.
3. In cold areas, do not use a drain elbow, drain plugs and adrain
hose with the outdoor unit. (Otherwise, drain watermay freeze,
impairing heating performance.)
The outdoor unit must be installed in such a way, so as to
prevent short circuit of the hot discharged air or obstruction to
the smooth air fl ow. Please follow the installation clearances
shown in the fi gure. Select the coolest possible place where
intake air temperature is not greater than the outside air
temperature (Refer to operating range).
