General Installation Information
WARNING: Before performing service or
maintenance operations on a system, turn off main
power switches to the unit. If applicable, turn off
the accessory heater power switch. Electrical
shock could cause personal injury.
Installing and servicing heating and air conditioning
equipment can be hazardous due to system pressure and
electrical components. Only trained and qualified service
personnel should install, repair or service heating and air
conditioning equipment. Untrained personnel can perform
the basic maintenance functions of cleaning coils and
cleaning and replacing filters. All other operations should
be performed by trained service personnel. When working
on heating and air conditioning equipment, observe
precautions in the literature, tags and labels attached to the
unit and other safety precautions that may apply.
Follow all safety codes. Wear safety glasses and work
gloves. Use a quenching cloth for brazing operations and
have a fire extinguisher available.
Moving and Storage
Move units in the normal "up" orientation. Do not stack
more than two units in total height. Do not attempt to
move units while stacked. When the equipment is received,
all items should be carefully checked against the bill of
lading to be sure all crates and cartons have been received.
Examine units for shipping damage, removing the units
from the packaging only if necessary. Units in question
should also be internally inspected. If any damage is noted,
the carrier should make the proper notation on the delivery
receipt, acknowledging the damage.
Exercise care when moving the unit. Do not remove any
packaging until the unit is near the place of installation.
Rig the unit by attaching chain or cable slings to the lifting
holes provided in the base rails. Spreader bars, whose length
exceeds the largest dimension across the unit, MUST be used
across the top of the unit.
If a unit is to be installed on a roof curb
gasketing must be applied to all surfaces that
come in contact with the unit underside.
AFFINITY SERIES OUTDOOR PACKAGED HEAT PUMP INSTALLATION MANUAL
Before lifting, make sure the unit weight is
distributed equally on the rigging cables so it will
lift evenly.
Units may be moved or lifted with a forklift. Slotted
openings in the base rails are provided for this purpose.
Fork must be at least 59 inches long.
All panels must be secured in place when the
unit is lifted.
Unit Location
Locate the Packaged Heat Pump away from areas that
may disturb the customer and in a way that allows easy
removal of the access panels and the top of the cabinet.
Provide sufficient room to make water and electrical
connections, and allow space for service personnel to
perform maintenance. The Packaged Heat Pump is approved
for outdoor installation when properly installed. Open
loop applications are to be installed in locations where the
ambient temperature never drops below 32˚F. Failure to
do so will result in failure of the heat pump. Closed loop
applications need to ensure that antifreeze is used to ensure
the freeze protection is below the ambient temperature.
Fork Pocket Covers
There are eight fork pocket covers and mounting screws
provided with the unit. Once the heat pump is set in place,
secure the fork pocket covers to the base rails with provided
screws to close off the base rail openings.
