Ground-Loop Heat Pump Applications
Figure 7: Loop Connection (Indoor
Compressor Section)
NOTICE! Cabinet opening around loop piping (outdoor
compressor section) must be sealed to prevent entry of
rodents that could potentially damage unit wiring by chewing
on the insulation.
NOTICE! Outdoor compressor section may not be tilted
more than 5 degrees from level. Damage to the compressor
or stress on the loop piping could result if unit is tilted. A
concrete pad, anchor posts and/or soil compaction may be
required to avoid tilting as ground settles.
