HEAT PUMP INSTALLATION
General Information
The T5BP series heat pump is designed only for outdoor
rooftop or ground level installations. This unit has been
tested for capacity and effi ciency in accordance with
A.R.I. Standards and will provide many years of safe
and dependable comfort, providing it is properly installed
and maintained. Abuse, improper use, and/or improper
maintenance can shorten the life of the appliance and
create unsafe hazards.
To achieve optimum performance and minimize equipment
failure, it is recommended that periodic maintenance be
performed on this unit. The ability to properly perform
maintenance on this equipment requires certain
mechanical skills and tools.
Before You Install the Heat Pump
The cooling load of the area to be conditioned must be
calculated and a system of the proper capacity selected.
It is recommended that the area to be conditioned be
completely insulated and vapor sealed.
Check the electrical supply and verify the power supply
is adequate for unit operation. The system must be wired
and provided with circuit protection in accordance with
local building codes. If there is any question concerning
the power supply, contact the local power company.
The indoor section (air handler, furnace, etc) should be
installed before routing the refrigerant tubing. Refer to
the indoor unit's installation instructions for installation
details.
All units are securely packed at the time of shipment and
upon arrival should be carefully inspected for damage
prior to installing the equipment at the job site. Verify
coil fi ns are straight. If necessary, comb fi ns to remove
fl attened or bent fi ns. Claims for damage (apparent or
concealed) should be fi led immediately with the carrier.
Please consult your dealer for maintenance information
and availability of maintenance contracts. Please read
all instructions before installing the unit.
Locating the Heat Pump
• Survey the job site to determine the best location for
mounting the outdoor unit.
• Overhead obstructions, poorly ventilated areas, and
areas subject to accumulation of debris should be
avoided.
• Suffi cient clearance for unobstructed airfl ow through the
outdoor coil must be maintained in order to achieve rated
performance. See Figure 2 for minimum clearances to
obstructions.
• Consideration should be given to availability of electric
power, service access, noise, and shade.
