DESCRIPTION
The heat pump condensing unit is the outdoor part of a versatile system of heating and air conditioning. It is designed to be
custom-matched with one of UPG’s complete line of evaporator sections, with each serving a specific function. Matching
Air Handlers are available for upflow, downflow, or horizontal
applications to provide a complete system. Electric Heaters
are available, if required. Add-on coils are available for use
with upflow, downflow, or horizontal furnaces and air handlers.
WARRANTY
Single Phase Units:
5-year limited parts warranty.
5-year limited compressor warranty.
FEATURES
• QUALITY CONDENSER COILS - The coil is constructed
of copper tubing and enhanced aluminum fins for
increased efficiency and corrosion protection.
• PROTECTED COMPRESSOR - The compressor is internally protected against high pressure, temperature, and
externally by a factory installed high pressure switch. This
is accomplished by the simultaneous operation of high
pressure relief valve and a temperature sensor which protects the compressor if undesirable operating conditions
occur. A liquid line filter-drier further protects the compressor.
• DURABLE FINISH - The cabinet is made of pre-painted
steel. The pre-treated galvanized steel provides a better
paint to steel bond, which resists corrosion and rust creep.
Special primer formulas and matted-textured finish insure
less fading when exposed to sunlight.
• LOWER INSTALLED COST - Installation time and costs
are reduced by easy power and control wiring connections. Available in sweat connect models only. The unit
contains enough refrigerant for matching indoor coils and
15 feet of interconnecting piping. The small base dimension means less space is required on the ground or roof.
• TOP DISCHARGE - The warm air from the top mounted
fan is blown up away from the structure and any landscaping. This allows compact location on multi-unit applications.
• LOW OPERATING SOUND LEVEL - The upward air flow
carries the normal operating noise away from the living
area. The rigid top panel effectively isolates any motor
sound. Isolator mounted compressor and the rippled fins
of the condenser coil muffle the normal fan motor and
compressor operating sounds.
• LOW MAINTENANCE - Long life permanently lubricated
motor-bearings need no annual servicing.
• EASY SERVICE ACCESS - Fully exposed refrigerant connections, and a single panel covering the electrical controls make for easy servicing of the unit.
• SECURED SERVICE VALVES - Secured re-usable ser-
vice valves are provided on both the liquid and vapor
sweat connections for ease of evacuating and charging.
• U.L. and C.U.L. listed - approved for outdoor application.
Certified in accordance with the Unitary Small Equipment certification program, which is based on ARI Standard 210/240.

Additional R-410A Charge / Orifice Size for Various Matched Systems
1. For applications requiring a TXV use 1TVM900 series kit.
2. Approved orifice shipped with outdoor unit.
3. Systems matched with furnace or air handlers not equipped with blower-off delays may require blower Time Delay Kit 2FD06700224.
4. PC coils cannot be used in downflow or horizontal applications. FC coils cannot be used in horizontal applications.
PROCEDURES:
1. Unit factory charge listed on the unit nameplate includes refrigerant for the condenser, the smallest evaporator and 15 feet of interconnecting line tubing.
2. Verify the TXV or orifice and additional charge required for specific evaporator coil in the system using the above table.
3. Additional charge for the amount of interconnecting line tubing greater than 15 feet at the rate specified in Physical and Electrical Data
Table.
4. For TXV match charge weight needs to be weighed in for specififc coil match and lineset length.
5. Permanently mark the unit nameplate with the total system charge. Total System Charge = Base Charge (as shipped) + adder for evaporator + adder for line set.

F*FP Air Handlers come with a factory installed R-22 TXV which MUST BE CHANGED OUT to R-410A TXV or an orifice for proper operation. If the TXV is not changed out system damage will occur.
Rated in accordance with DOE test procedures (Federal Register 12-27-79 and 3-18-88) and ARI Standards 210.
Cooling MBH based on 80°F entering air temperature, 50% RH, and rated air flow.
EER (Energy Efficiency Ratio) is the total cooling output in BTU’s at 95°F outd oor ambient divided by the total electric power in watt-hours at those conditions.
SEER (Seasonal Energy Efficiency Ratio) is the total cooling output in BTU’s during a normal annual usage period for cooling divided by the total electric power
input in watt-hours during the same period.
