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.

Rigging and Hoisting

 WARNING:

To avoid the risk of property damage, personal 
injury, or death, it is the rigger’s responsibility 
to ensure that whatever means are used to hoist 
the unit are safe and adequate:

• 

The lifting equipment must be adequate for the 
load. Refer to Table 3 (page 14) for unit weights.

• 

The unit must be lifted from the holes in the 
base rails using cables or chains.

• 

Spreader bars are required to protect the unit 
and ensure even loading.

• 

Keep the unit in an upright position at all times. 

• 

All panels must be securely in place during 
rigging and hoisting.

Rooftop

Rooftop installations must be located according to local 
building codes or ordinances and these requirements:
•  Units may be installed on Class A, B, or C roof covering 

material. The roof must be capable of handling the 
weight of the unit. For unit weights, see Table 3. 
Reinforce the roof if necessary.

•  Secure optional mounting pad or frame to roof using 

acceptable mechanical methods per local codes.

Packaging Removal

Locate and remove all screws securing the unit to the 
shipping skid. 

NOTE: 

To prevent damage to the tubing 

connections, carefully remove the carton and user’s 
manual from the equipment. Discard the shipping carton.
