In Canada refer to the current editions of the Canadian Electrical Code
CSA C22.1.
Recognize safety information. This is the safety-alert symbol . When
you see this symbol on the unit and in instructions or manuals, be alert to
the potential for personal injury. Understand these signal words:
DANGER, WARNING, and CAUTION. These words are used with the
safety-alert symbol. DANGER identifies the most serious hazards which
will result in severe personal injury or death. WARNING signifies
hazards which could result in personal injury or death. CAUTION is
used to identify unsafe practices which may result in minor personal
injury or product and property damage. NOTE is used to highlight
suggestions which will result in enhanced installation, reliability, or
operation.
Introduction
This heat pump is fully self-contained and designed for outdoor
installation. (See
) Standard units are shipped in a
horizontal-discharge configuration for installation on a ground level
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 before removing packaging material. 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.
If the unit is to be mounted on a curb in a downflow application, review
Step 5 to determine which method is to be used to remove the downflow
panels before rigging and lifting into place. The panel removal process
may require the unit to be on the ground.
Step 2 – Provide Unit Support
Roof Curb
Install accessory roof curb in accordance with instructions shipped with
curb (See
). 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
). This is
necessary for unit drain to function properly. Refer to accessory roof
curb installation instructions for additional information as required.
Installation on older “G” series roof curbs.
Two accessory kits are available to aid in installing a new “G” series unit
on an old “G” roof curb.
1. Accessory kit number CPADCURB001A00, (small chassis) and
accessory kit number CPADCURB002A00, (large chassis) includes
roof curb adapter and gaskets for the perimeter seal and duct
openings. No additional modifications to the curb are required
when using this kit.
2. An alternative to the adapter curb is to modify the existing curb by
removing the outer horizontal flange and use accessory kit number
CPGSKTKIT001A00 which includes spacer blocks (for easy
alignment to existing curb) and gaskets for the perimeter seal and
duct openings. This kit is used when existing curb is modified by
removing outer horizontal flange.
Slab Mount
Place the unit on a solid, level pad that is at least 2 in. (51 mm) above
). The pad should extend approximately 2 in. (51 mm)
beyond the casing on all 4 sides of the unit. Do not secure the unit to the
pad except when required by local codes.
Step 3 – Provide Clearances
The required minimum service clearances are shown in
- .
Adequate ventilation and outdoor air must be provided. The outdoor fan
WARNING
!
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury or death.
Before installing or servicing system, always turn off main power to
system and install lockout tag. There may be more than one disconnect
switch. Turn off accessory heater power switch if applicable.
CAUTION
!
CUT HAZARD
Failure to follow this caution may result in personal injury.
When removing access panels (see
or performing maintenance
functions) inside your unit, be aware of sharp sheet metal parts and
screws. Although special care is taken to reduce sharp edges to a
minimum, be extremely careful and wear appropriate clothing, safety
glasses and gloves when handling parts or reaching into the unit.
WARNING
!
PERSONAL INJURY AND PROPERTY DAMAGE
HAZARD
For continued performance, reliability, and safety, the only approved
accessories and replacement parts are those specified by the equipment
manufacturer. The use of non-manufacturer approved parts and
accessories could invalidate the equipment limited warranty and result
in fire risk, equipment malfunction, and failure. Please review
manufacturer's instructions and replacement part catalogs available
from your equipment supplier.
NOTICE
!
If the unit gasketing or insulation must be replaced, ensure the material
used is compliant with the two agency requirements listed.
1. Insulation and adhesives shall meet NFPA 90.1 requirements for
flame spread and smoke generation.
2. Cabinet insulation shall meet ASHRAE Standard 62.2.
CAUTION
!
UNIT/STRUCTURAL DAMAGE HAZARD
Failure to follow this caution may result in property damage.
Ensure there is sufficient clearance for saw blade when cutting the outer
horizontal flange of the roof curb so there is no damage to the roof or
flashing.
