Side Discharge Condensers 3
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 24
v
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.
