These packagedheatpumpsaredesignedforoutdoorinstallation. Only utility and duct connections are required at the point of installation.

Field-installed electric heater accessories are available to provide electric heat, if required.

STANDARD FEATURES / BENEFITS

OPERATING EFFICIENCY - All units provide high operating

efficienciesof10SEERorgreater,3.0COP or greater andup to

7.0 HSPF. All efficiencies exceed legislated minimum levels. ON SITE FLEXIBILITY - All model sizes share a common,

compact design cabinet with a single footprint. The installer has the flexibility of setting one curb or pad and placing the proper tonnage unit on that curb after the internal load has been determined. Field convertible duct connections from side shot to down shot allows the installer to have greater flexibility and needs to carry less inventory.

LOWER INSTALLATION COST - Installation timeand costs are reduced by easy power and control wiring connections. The small base dimension means less space is required on the ground orroof, plus,the installercan fitthis unit between the wheel wells of full size pick-up truck. All models are well under 500 pounds.

tistics such as system pressure, motor currents, air velocityand temperature and unit vibration are monitored and recorded by the system to insure unit performance.

NOTE: 1. Deduct these resistance values from the available external static pressure shown in the respective Blower Performance Table.

2. The pressure thru the economizer is greater for 100% outdoor air then for 100% return air. If the resistance of the return air duct system is less then 0.25 IWG, the unit will deliver less CFM during full economizer operation.
