HEAT PUMP INSTALLATION

General Information

Split system heat pumps are designed only for outdoor

rooftop or ground level installations. This unit has been

tested for capacity and efﬁciency in accordance with

AHRI 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.

Refer to the Quick Reference Data sheet for additional

electrical, charging and unit information.

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 ﬁns are straight. If necessary, comb ﬁns to remove

ﬂattened or bent ﬁns. Claims for damage (apparent or

concealed) should be ﬁled 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. See Figure 1.

• Sufcientclearanceforunobstructedairowthroughthe

outdoor coil must be maintained in order to achieve rated

performance. See Figure 1 for minimum clearances to

obstructions.

• Considerationshouldbegiventoavailabilityofelectric

power, service access, noise, and shade.

Packaging Removal

To prevent damage to the tubing onnections, carefully

remove the carton and user’s manual from the equipment.

Discard the shipping carton.

Ground Level

Ground level installations must be located according to

local building codes or ordinances and these requirements:

• Clearancesmustbeinaccordancewiththoseshown

in Figure 1.

• A suitable mounting pad must be provided and be

separate from the building foundation. The pad must

be level and strong enough to support the unit’s weight.

The slab height must be a minimum of 2” (5 cm) above

grade and with adequate drainage. See Figure 1.

Rooftop

• Themethodofmountingshouldbedesignedsothatit

does not overload roof structures or transmit noise to

the interior of the structure. The roof must be structurally

capable of handling the weight of the unit.

• Full perimeter support is required under the unit.

Support must be made of weather resistant materials

and installed prior to unit installation.

• Thesupportmustbebuilttoraisetheunit6"abovethe

roof.
