it in a dry location with the motor protected against
moisture, dust, corrosion and physical damage.
PREPARE CEILING FOR MOUNTING
Depending upon building construction, provisions
for mounting the unit must be made by the contractor
according to architects; drawings.
It is important to ensure that the fan coils are securely
mounted and the structure is sufficient to support the
weight of the equipment. All anchors for mounting the
equipment must be placed and sized to ensure a safe
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.
Unit must not be operated during
building construction due to ex-
cessive airborne dust and debris. The
units must not be operated under any
circumstances without an air filter in
place.
WIRING
All wiring must comply with the local and national code
requirements. Units are provided with wiring diagrams
and nameplate data to provide information required for
necessary field wiring.
For power wiring a 4 x 4 electrical box is provided on
the cabinet for connection of power supply and is located
on the same side as piping.
On YHBC units, the box is shipped unattached, it is
field 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 field 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.
In free (non-ducted return air) return installations of
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.
