Prepunched Opening for Outdoor
Installation of an Air-Water Heat
Pump
A prepunched opening (1) for the lines
routed from the rear of the enclosure
into the ground is provided in the unit
bottom behind the electrical panel.
We recommend routing the lines this
way for the heat pump installed
outdoors. This involves pulling the
heating lines, condensate connection,
and the electrical cables through the
opening.
