Minimum Clearances - Viessmann VITOCAL 300-A Installation And Service Instructions Manual

External heat pump type AW-O-M

Minimum clearances

Foundations
The heat pump must be placed hori-
zontally on a permanently solid sur-
face. We recommend laying concrete
foundations as shown in the following
diagrams.
Provide an adequately sized
recess B in the foundations to permit
the lines (heating flow and return,
electrical cables and condensate
drain) to be brought into the heat
pump from below.
Preparing for installation
(cont.)
The foundations, supporting surface
and cable ducts must be designed to
prevent rodents from entering the
heat pump and the cable ducts.
The condensate that is created must
either be led out via an existing drain
pipe or be able to soak away into a
coarse bed of gravel.
