RECEIVING AND INSTALLATION
I. STEP 1 — CHECK EQUIPMENT
A. Identify Unit
The unit model number and serial number are stamped on
unit identification plate. Check this information against ship-
ping papers and job data.
B. Inspect Shipment
Inspect for shipping damage while unit is still on shipping
pallet. If unit appears to be damaged or is torn loose from its
anchorage, have it examined by transportation inspectors be-
fore removal. Forward claim papers directly to transporta-
tion company. Manufacturer is not responsible for any dam-
age incurred in transit.
Check all items against shipping list. Immediately notify the
nearest Bryant Air Conditioning office if any item is missing.
To prevent loss or damage, leave all parts in original pack-
ages until installation.
II. STEP 2 — PROVIDE UNIT SUPPORT
A. Roof Curb
Install accessory roof curb in accordance with instructions
shipped with curb. See Fig. 4 for roof curb dimensions. In-
stall insulation, cant strips, roofing, and flashing. Ductwork
must be attached to curb.
IMPORTANT: The gasketing of the unit to the roof curb is
critical for a watertight seal. Install gasketing material sup-
plied with the roof curb. Improperly applied gasketing can
result in water leaks, air leaks, and poor unit performance.
Curb should be level to within 1 ⁄
4
inch. This is necessary for
unit drain to function properly. Refer to accessory roof curb
installation instructions for additional information as
required.
B. Slab Mount
Place the unit on a solid, level concrete pad that is a mini-
mum of 4 in. thick with 2 in. above grade. The slab should be
flush on the compressor end of the unit (to allow condensate
drain installation) and should extend 2 in. on the three re-
maining sides of the unit. See Fig. 5. Do not secure the unit
to the slab except when required by local codes.
C. Ground Mount
The unit may be installed either on a slab or placed directly
on the ground if local codes permit. Place the unit on level
ground prepared with gravel for condensate discharge.
III. STEP 3 — FIELD FABRICATE DUCTWORK
Secure all ducts to roof curb and building structure on verti-
cal discharge units. Do not connect ductwork to unit. For hori-
zontal applications, unit is provided with flanges on the hori-
zontal openings. All ductwork should be secured to the flanges.
Insulate and weatherproof all external ductwork, joints,
and roof openings with counter flashing and mastic in
accordance with applicable codes.
Ducts passing through an unconditioned space must be in-
sulated and covered with a vapor barrier.
If a plenum return is used on a vertical unit, the return should
be ducted through the roof deck to comply with applicable
fire codes.
A minimum clearance is not required around ductwork. Cabi-
net return-air static shall not exceed −.25 in. wg.
IV. STEP 4 — PROVIDE CLEARANCES
The required minimum operating and service clearances are
shown in Fig. 2 and 3. Adequate combustion, ventilation, and
condenser air must be provided, in accordance with section
5.3, Air for Combustion and Ventilation, of the National Fuel
Gas Code ANSI (American National Standards Institute) Z223.1
(in Canada, sections 7.2, 7.3 or 7.4 or Can/CGA [Canadian
Gas Association] B149 Installation Codes), or applicable pro-
visions of local building code.
CAUTION:
Do not restrict condenser airflow. An air
restriction at either the outdoor-air inlet or the fan dis-
charge can be detrimental to compressor life.
The condenser fan pulls air through the condenser coil and
discharges it through the top cover. Be sure that the fan dis-
charge does not recirculate to the condenser coil. Do not lo-
cate the unit in either a corner or under an overhead obstruction.
The minimum clearance under a partial overhang (such as a
normal house overhang) is 48-in. above the unit top. The maxi-
mum horizontal extension of a partial overhang must not ex-
ceed 48 inches.
Do not place the unit where water, ice, or snow from
an overhang or roof will damage or flood the unit. Do not in-
stall the unit on carpeting, tile, or other combustible
materials. The unit may be installed on wood flooring or on
Class A, B, or C roof covering materials.
V. STEP 5 — RIG AND PLACE UNIT
CAUTION: When installing the unit on a rooftop, be
sure the roof will support the additional weight.
Use spreader bars or crate top when rigging the unit. The
units must be rigged for lifting as shown in Fig. 6. Refer to
Tables 1 and 2 for operating weight. Use extreme caution to
prevent damage when moving the unit. Unit must remain in
an upright position during all rigging and moving opera-
tions. The unit must be level for proper condensate drainage;
therefore, the ground-level pad or accessory roof curb must
be level before setting the unit in place. When a field-
fabricated support is used, be sure that the support is level
and properly supports the unit.
