DESCRIPTION

The 13 SEER Series condensing unit is the outdoor part of a

versatile system of air conditioning. It is designed to be cus-

tom-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 han-

dlers.

WARRANTY

Single Phase Units:

5-year limited parts warranty.

5-year limited compressor warranty.

FEATURES

•QUALITY CONDENSER COILS - The coil is constructed

of aluminum microchannel tubing and enhanced aluminum

fins for increased efficiency and corrosion protection.

•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 - 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 connec-

tions. 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

compressor operating sounds.

•LOW MAINTENANCE - Long life permanently lubricated

motor-bearings need no annual servicing.

•EASY SERVICE ACCESS - Fully exposed refrigerant con-

nections, and a single panel covering the electrical con-

trols 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 inter-

connecting 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.

Models 12-48 require start kits for TXV matches. Models with “H” on the end of the model number have factory installed start kits.

For models without an “H” refer to tech guide for kit number reference.

F*FP Air Handlers come with a factory installed R-22 TXV. Please note that some models may take a different TXV then what is factory

installed. The proper TXV must be installed for system reliability and performance. Also note, TXV must be removed for orifice match.

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 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.
