Drain Kits
Drain kits are recommended for the heat pump
units, and may be used on any unit as required.
They eliminate excessive condensate accumulation
which is generated during the heating cycle of the
heat pump.
There are two types of drain kits employed with
the Packaged Terminal equipment; internal drains
and external drains.
Internal Drain
An internal drain is mounted to the bottom of
the wall sleeve prior to installation of the sleeve.
Position this drain on the room side of the sleeve
and connect to an internal collection system.
When using a subbase, a 3" × 5" opening is
provided in the subbase for plumbing to the drain.
External Drain
The external drain is attached to the rear of the
wall sleeve, over one of the weep holes. A cap is
provided to seal the remaining weep hole to force
the excessive condensate to one side.
The excess condensate is then evacuated from the
wall sleeve and allowed to drain to the outside of
the building.
