Failure to follow this caution may result in personal i njury.
When removing access panels (see Fig. 21) or pe rforming
maintenance functions inside your unit, be aware of sharp

CAUTION
INTRODUCTION
The 607----A heat pump is fully self--contained and designed for
outdoor installation. (See Fig. 1) 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 I NSTALLATION
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 compa ny.
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 int o 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 Fig. 4) . Ins tall 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. 7). 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 a vailable to aid in installin g a ne w “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 num ber CPGSKTKIT001A00 which includes
spacer blocks (for easy alignment to exi sting c urb) and
gaskets for the perimeter seal and duct openings. This kit is
used when existing curb is modified by removing outer
horizontal flange.
UNIT/STRUCTURAL DAMAGE HAZARD
Failure to follow this caution may result in prope rty damage.
Ensurethereis sufficientclearanceforsaw bladewhen cutting
the outer horizontal flange of the roof curb so there is no
damage to the roof or flashing.

CAUTION
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. 8).
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 code s.
Step 3 — Provide Clea rances
The requi red minimum service c learances are sho wn in Fig. 2 and
3. Adequate ventilation and out door 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
extens ion of a partial ove rhang 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 t o compr essor 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.
