DESCRIPTION
The 10 SEER Series heat pumps is the outdoor part of a ver-
satile system of heat pumps. It is designed to be custom-
matched with one of UPG’s complete line of evaporator sec-
tions, with each serving a specific function. Matching Air Han-
dlers 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 han-
dlers.
WARRANTY
1-year limited parts warranty.
5-year limited compressor warranty.
FEATURES
•QUALITY COILS - The coil is constructed of copper tube
and aluminum fins.
•COIL PROTECTION - Coils are protected from damage by
a polymer mesh applied between the coil face, and a PVC
coated steel coil guard.
•PROTECTED COMPRESSOR - The compressor is inter-
nally protected against high pressure and temperature.
This is accomplished by the simultaneous operation of
high pressure relief valve and a temperature sensor which
protects the compressor if undesirable operating condi-
tions occur. A liquid line filter-drier further protects the
compressor.
•DURABLE FINISH - Cabinet is made of pre-painted steel.
The pre-treated flat 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.
Discharge line heat exchanger knockouts are provided, if
required. Available in sweat connect models only. The unit
contains enough refrigerant for matching indoor coils and
15 feet of interconnecting piping. The small base dimen-
sion 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 landscap-
ing. This allows compact location on multi-unit applica-
tions.
•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 com-
pressor operating sounds.
•LOW MAINTENANCE - Long life permanently lubricated
motor-bearings need no annual servicing.
•EASY SERVICE ACCESS - Fully exposed refrigerant con-
nections, a single panel covering the electrical controls,
and the molex plug in the control box connecting the con-
denser fan 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 cer-
tification program, which is based on ARI Standard 210/240.

PROCEDURES:
1. Unit factory charge listed on the unit nameplate includes refrigerant for the condenser, the smallest evaporator and 15 feet of intercon-
necting line tubing.
2. Verify the orifice size and additional charge required for specific evaportor 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 the table above.
4. Permanently mark the unit nameplate with the total system charge. Total System Charge = Base Charge (as shipped) + adder for
evaportor + adder for line set.
5. If the orifice in the evaportor was changed, verify the evaportor nameplate has been marked with the correct orifice size.

Rated in accordance with DOE test procedures (Federal Register 12-27-79 and 3-18-88) and ARI Standards 210/240.
Cooling MBH based on 80°F entering air temperature, 50% RH, and rated air flow.
KW includes compressor, outdoor fan and indoor blower motor watts. Add-on coils include 365 watts/1000 CFM for blower motor.
EER (Energy Efficiency Ratio) is the total cooling output in BTU’s at a 95°F outdoor 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.
1. G2FD coils available with a factory installed horizontal drain pan. See price pages for specific model number.
2. Single phase units require single phase 2HK heaters.
3. TXV = Use 1TV700 Series Kit.
4. To meet R=4.2 insulation requirements, substitute F2FP for F2RP, and F2FC for F2RC. models. All ratings remain the same.
5. FG8, FG9, and FL8 furnaces and F2RP / F2RC air handlers have B.O.D. standard.
