First Co HBC (X) - Manual

GENERAL
The manufacturer assumes no re-
sponsibility for equipment installed in
violation of any code requirement.
These instructions give information
relative to the installation of these fan
coil units only. For other related
equipment refer to the proper instruc-
tions.
Material in this shipment has been
inspected at the factory and released
to the transportation agency in good
condition. When received, a visual
inspection of all cartons should be
made immediately. Any evidence of
rough handling or apparent damage
should be noted on the delivery re-
ceipt and the material inspected in the
presence of the carrier's representa-
tive. If damage is found, a claim
should be filed against the carrier im-
mediately.
FAN COIL UNIT
The installer must adhere strictly to
all local and national code require-
ments pertaining to the installation of
this equipment. The HBC, PHBC, and
RHBC units are designed for installa-

tion in a horizontal position above a
dropped ceiling. The CHBC is a cabi-
net unit intended for horizontal ex-
posed surface mounting.
In a HBC free return installation
(non-ducted return air), the furred
down area must be completely sealed
(except return air grille) to ensure that
all return air is pulled from the condi-
tioned space and not from other areas
of the building structure.
Access must be provided for servic-
ing 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 ac-
cess to electrical and plumbing con-
trols.
While most fan coil units are U.L.
Listed for installations with zero clear-
ance to combustible materials, refer-
ence should be made to the marking
on the particular unit being installed
where specific information regarding
clearances is provided.
AIR DISTRIBUTION
DUCTS
All duct work must be installed in
accordance with National Fire Protec-
tion Association Codes 90A and 90B.
Ducts should be adequately insulated
to prevent condensation during the
cooling cycle and to minimize heat
loss during the heating cycle. All
return air must be filtered to prevent
dirt buildup on the coil surface. If there
is no ducted return, applicable instal-
lation codes may limit the unit to in-
stallation only in a single story resi-
dence. In many cases it is acceptable

to use ducting of the same size as the
fan coil connections. However,
unique arrangements or long duct
runs must be confirmed by a local
professional. The manufacturer will
not be responsible for misapplied
equipment.
ELECTRICAL
All wiring must comply with local
and national code requirements.
Units are provided with wiring dia-
grams and nameplate data to provide
information required for necessary
field wiring.
These units may be provided with a
optional Class 2 transformer for 24-
volt control circuits. Should any add-
on equipment also have a Class 2
transformer furnished, care must be
taken to prevent interconnecting out-
puts of the two transformers by using
a thermostat with isolating contacts.
