PRODUCT DESCRIPTION

The AmericaSeries S1C/H and S2C condensing units are, air-cooled, vertically arranged side discharge, high efficiency units designed specifically to meet or ex- ceed a 13 SEER rating.

The S1C 9,000-36,000 Btuh and S1H 9,000-24,000 Btuh capacity condensing unit will provide cooling for a single evaporator, as identified in the "S1C Specifications and Dimensions" section on pages 23-24.

The S2C 18,000 (99) - 21,000 (92) and 23,000 (22) Btuh capacity condensing units will provide cooling for two evaporators, as identified on page 25 in the "S2C Specifica- tions and Dimensions" section. The S1C/H and S2C are quiet units that can be recom- mended for both commercial and residential applications.

Installation of the S1C/H and S2C condensing units is simplified by a 24v control interconnection from the evaporator and multiple units can be lined up in close proximity to an exterior wall. Service valves are recessed to reduce tampering and all 9,000-12,000 Btuh units are equipped with a Duratec Performance Package that includes an oversized suction accumula- tor with surge baffles and enhanced oil management, a factory installed solid core filter drier and loss of charge switch. A field installed crankcase heater is standard on S1H 09 &12 (Thermostatically controlled) models, and is available as optional equip-

ment on other models.

ITEMS FOR CONSIDERATION

CONTROLS and COMPONENTS

(Factory installed or supplied)

•Compressor and fan motor contactor

•Run capacitor

•Loss of charge switch (09 - 12 only)

•Low voltage terminal connections

•Large capacity suction accumulator (09 - 12 only)

•Solid core filter drier (09 - 12 only)

•Thermostatically controlled crankcase heater (09 - 12 S1H’s)

•H.P.S. (High pressure switch)

-Standard on S1H’s (heat pumps)

-Standard on S1C’s 18K and above.

•Low Ambient controls for operation down to 32º F standard, factory in- stalled on all S1H’s (heat pumps)

Thermostatically controlled crankcase heater – This feature energizes the crank- case heater only when needed, removes the heater from the electrical circuit at conditions where it’s not required, saving unnecessary Watts, and increasing overall system efficiency.

System OPTIOns

•Field installed crankcase heater for straight cool units (standard on 9,000-12,000 Btuh S1H’s Thermostati- cally controlled)

•Straight cool hard start (standard on all S1H’s)

•115v (9,000-12,000 btuh only)

•copper/copper coils (sea coast use)

•Low Ambient controls for operation down to 32º F, specify this option for S1C or S2C systems (standard on S1H’s) that will be operated in cooling mode at outside temperatures below 60º F (field installed kit)

•Low Ambient for operation down to 0º F for S1C, S1H or S2C systems (consult factory for availability)

Low Ambient controls are required when the system is asked to cool at outdoor tem- peratures below 60º F, this may cause dam- age to the compressor and coil, and may
