and durable installation.
The YHBC, YPHBC, YRHBC, YHH, YHHS, YPHH,
YHYB, and YPHYB units are designed for installation
in a horizontal position above a dropped ceiling. The
YCHBC is a cabinet unit intended for horizontal
exposed surface mounting.

building construction due to ex-
cessive airborne dust and debris. The
units must not be operated under any
circumstances without an air lter in
place.

requirements. Units are provided with wiring diagrams
and nameplate data to provide information required for
necessary eld wiring.
For power wiring a 4 x 4 electrical box is provided on

on the same side as piping.
On YHBC units, the box is shipped unattached, it is
eld attached to the unit in a location convenient to
electrical entrance.
Any devices such as fan switches or
thermostats that have been furnished
by the factory for eld installation
must be wired in strict accordance
with the wiring diagram that is sup-
plied with the unit. Failure to do so
could result in damage or injury.

YHBC, YHH, YHHS and YHYB units; the furred
down area must be completely sealed (except return
air grille) to ensure that all return air is pulled from
the conditioned space and not from other areas of the
building structure.
Access must be provided for servicing the unit. If
this access is provided by a removable ceiling panel,
ample space must be allowed for removal of the blower
panel and to provide access to electrical and plumbing
controls.
