INTRODUCTION
The 604D heat pump is fully self- -contained and designed for
outdoor installation. (See Fig. 1) Standard units are shipped in a
horizontal- -discharge
configuration
groundlevel slab. Standard units can be converted to downflow
(vertical) discharge configurations for rooftop applications.
RECEIVING AND INSTALLATION
Step 1 — Check Equipment
IDENTIFY UNIT
The unit model number and serial number are stamped on the
unit identification plate. Check this information against shipping
papers.
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 before removal.
Forward claim papers directly to transportation company.
Manufacturer is not responsible for any damage incurred in
transit. Check all items against shipping list. Immediately notify
the nearest equipment distributor if any item is missing. To
prevent loss or damage, leave all parts in original packages until
installation.
Step 2 — Provide Unit Support
ROOF CURB
Install accessory roof curb in accordance with instructions
shipped with curb (See Fig. 5). Install 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 supplied
with the roof curb. Improperly applied gasketing also can result
in air leaks and poor unit performance.
Curb should be level to within 1/4 in. (6 mm)(See Fig. 6). This is
necessary for unit drain to function properly. Refer to accessory
roof curb installation instructions for additional information as
required.
SLAB MOUNT
Place the unit on a solid, level concrete pad that is a minimum of
4 in. (102 mm) thick with 2 in. (51 mm) above grade (See Fig. 7).
The slab should extend approximately 2 in.(51 mm) beyond the
casing on all 4 sides of the unit. Do not secure the unit to the slab
except when required by local codes.
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.
Step 3 — Provide Clearances
The required minimum service clearances are shown in Fig. 2 and
3. Adequate ventilation and outdoor air must be provided. The
outdoor fan draws air through the outdoor coil and discharges it
through the top fan grille. Be sure that the fan discharge does not
recirculate to the outdoor coil. Do not locate 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. (1219 mm) above the unit top. The maximum horizontal
extension of a partial overhang must not exceed 48 in. (1219
mm)
IMPORTANT: Do not restrict outdoor airflow. An air restriction
at either the outdoor- -air inlet or the fan discharge may be
detrimental to compressor life.
Do not place the unit where water, ice, or snow from an overhang
or roof will damage or flood the unit. Do not install the unit on
carpeting or other combustible materials. Slab- -mounted units
should be at least 4 in. (102 mm) above the highest expected
water and runoff levels. Do not use unit if it has been under water.
Step 4 — Rig and Place Unit
Rigging and handling of this equipment can be hazardous for many
reasons due to the installation location (roofs, elevated structures,
etc.).
Only trained, qualified crane operators and ground support staff
should handle and install this equipment.
When working with this equipment, observe precautions in the
literature, on tags, stickers, and labels attached to the equipment, and
any other safety precautions that might apply.
Training for operators of the lifting equipment should include, but
not be limited to, the following:
1. Application of the lifter to the load, and adjustment of the
lifts to adapt to various sizes or kinds of loads.
2. Instruction in any special operation or precaution.
3. Condition of the load as it relates to operation of the lifting
kit, such as balance, temperature, etc.
Follow all applicable safety codes. Wear safety shoes and work
gloves.
INSPECTION
The lifting/rigging bracket is engineered and designed to be
installed only on Small Packaged Products. This bracket is to be
used to rig/lift a Small Packaged Product onto roofs or other
elevated structures.
