Condensate Connections

A drain line must be connected to the heat pump
and pitched away from the unit a minimum of 1/8"
per foot to allow the condensate to flow away from
the unit.
This connection must be in conformance with local
plumbing codes. A trap must be installed in the
condensate line to ensure free condensate flow.
(Heat Pumps are not internally trapped).
A vertical air vent is sometimes required to avoid air
pockets.
The depth of the trap depends on the amount of positive
or negative pressure on the drain pan. A second trap
must not be included.
The horizontal unit should be pitched approximately
1/4" towards the drain in both Duct System
All LV Series models are provided with a return air duct
flange and supply air duct connections.

Refer to unit Dimensional Drawings for physical
dimensions of the collar and flange. Page# 55. A flexible
connector is recommended for supply and return air
duct connections on metal duct systems. All metal
ducting should be insulated with a minimum of 1" (one
inch) duct insulation to avoid heat loss or gain and
prevent condensate from forming during the cooling
operation. Application of the unit to non-insulated duct
work is not recommended as the unit's performance will
be adversely affected.
