Condensate Drain - Bosch CE025 Installation And Maintenance Manual

Mounting Vertical units
MounTInG VerTICal unITs
Vertical units up to six tons are available in left or
right air return configurations. Vertical units should
be mounted level on a vibration absorbing pad
slightly larger than the base to minimize vibration
transmission to the building structure. It is not
necessary to anchor the unit to the floor. (See
Figure #1).

While horizontal units may be installed on any level
surface strong enough to hold their weight, they are
typically suspended above a ceiling by threaded
rods. The rods are usually attached to the unit
corners by hanger bracket kits (See Figure #2). The
rods must be securely anchored to the ceiling. Refer
to the hanging bracket assembly and installation
instructions for details. Horizontal units installed
above the ceiling must conform to all local codes. An
auxiliary drain pan if required by code, should be at
least four inches larger than the bottom of the heat
pump.

Plumbing connected to the heat pump must
not come in direct contact with joists, trusses,
walls, etc.
Some applications require an attic floor installation
of the horizontal unit. In this case the unit should
be set in a full size secondary drain pan on top of a
vibration absorbing mesh. The secondary drain pan
prevents possible condensate overflow or water
leakage damage to the ceiling. The secondary drain
pan is usually placed on a plywood base isolated
from the ceiling joists by additional layers of
vibration absorbing mesh. In both cases, a 3/4"
drain connected to this secondary pan should be
run to an eave at a location that will be noticeable.
If the unit is located in a crawl space, the bottom of
the unit must be at least 4" above grade to prevent
flooding of the electrical parts due to heavy rains.

CondensaTe draIn

If equipped with float style condensate
overflow switch, final adjustment must be
made in the field.
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 insure free condensate flow.
(Heat Pumps are not internally trapped). A vertical
air vent is sometimes required to avoid air pockets.
(See Figure #3). The length of the trap depends on
the amount of positive or negative pressure on the
drain pan. A second trap must not be included.
