Considerations
Important:
Due to the unique design of this unit, which allows the
electrical wiring to be routed within the insulation , do not
screw, cut, or otherwise puncture the unit cabinet in any
location other than the ones illustrated in this Installer
Guide or in an approved accessory’s Installer Guide.
Important:
Make certain that the unit has been installed in a level
position to ensure proper draining.
Important:
Under no conditions should metal strapping be attached
to the unit to be used as support mechanisms for
carrying or suspension purposes.
1.
Support the unit from the bottom (near both ends). The service
access must remain unobstructed.
a.
Approved bottom support methods are rail, u-channels
(Unistrut
®
), or other load bearing materials.
b.
The unit must be isolated carefully to prevent sound
transmission. Field supplied vibration isolators are
recommended.
Important:
The unit can only be supported from the bottom unless
using kit BAYHHKIT001A. Do not drill or screw supports
into any area of the cabinet.
Note:
Do not allow the unit to be used as strain relief.
2.
Install an auxiliary drain pan under the horizontal air handler to
prevent possible damage to ceilings.
a.
Isolate the auxiliary drain pan from the unit and from the
structure.

Connect the auxiliary drain pan to a separate drain line and
terminate according to local codes.
