GENERAL INFORMATION
The Dual Fuel iHybrid™ heat pump is designed only for
outdoor rooftop or ground level installations and can be
readily connected to the duct system of a home.This unit
hasbeentestedforcapacityandefficiencyinaccordance
withA.H.R.I.Standardsandwillprovidemanyyearsofsafe
and dependable comfort, providing it is properly installed
and maintained. With regular maintenance, this unit will
operatesatisfactorilyyearafteryear.Abuse,improperuse,
and/or improper maintenance can shorten the life of the
appliance and create unsafe hazards.
Toachieveoptimumperformanceandminimizeequipment
failure, it is recommended that periodic maintenance be
performed on this unit. The ability to properly perform
maintenance on this equipment requires certain tools
and mechanical skills.
√Thecooling load of the area to beconditioned must be
calculatedandasystemofthepropercapacityselected.
It is recommended that the area to be conditioned be
completely insulated and vapor sealed.
√Checktheelectricalsupplyandverifythepowersupply
isadequateforunitoperation.Considerationshouldbe
given to availability of electric power, service access,
noise, and shade. If there is any question concerning
the power supply, contact the local power company.
√Allunitsaresecurelypackedatthetimeofshipmentand
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)shouldbefiledimmediatelywiththecarrier.
√Pleaseconsultyourdealerformaintenanceinformation
and availability of maintenance contracts. Read all
instructions before installing the unit.
• Surveythejobsitetodeterminethebestlocationfor
the packaged unit. The unit should be located with
consideration of minimizing the length of the supply
and return ducts.If practical, place the equipment and
its ducts in an area where they will be shaded from
the afternoon sun, when the heat load is greatest.
Considerationshould also be givento the accessibility
offuel,electricpower,serviceaccess,noise,andshade.
• Selectasolid,levelposition,preferablyonaconcrete
slab, slightly above the grade level, and parallel to the
home. DO NOT PLACE UNIT UNDER THE HOME.
• Overheadobstructions,poorly ventilatedareas,and
areas subject to accumulation of debris should be
avoided. Do not place the unit in a confined space or
recessed area where discharge air from the unit could
re-circulate back through the condenser coil.
• Sufcientclearanceforunobstructedairowthroughthe
louvered control access panel and outdoor coil must
be maintained in order to achieve rated performance.
See Figure 1 for minimum clearance requirements.
• Aclearanceofatleast36inchesfromthebloweraccess
panel and from the louvered control access panel is
recommended for servicing and maintenance.
• Thehotcondenserairmustbedischargedupandaway
from the home.
This unit should be sized to provide the design heating
load requirement. Heating load estimates can be made
using approved methods available from Air Conditioning
Contractors of America (Manual J); American Society of
Heating, Refrigerating, and Air Conditioning Engineers;
orother approvedengineering methods.Forinstallations
above 2,000 ft., the unit should have a sea level input
rating large enough that it will meet the heating load after
deration for altitude.
