PRODUCT DESCRIPTION
The AmericaSeries S1C/H and S2C
condensing units are, air-cooled, vertically
arranged side discharge, high efciency
units designed specically 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 identied in the "S1C Specications 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
identied on page 25 in the "S2C Specica-
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 simplied 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 bafes and enhanced oil
management, a factory installed solid core
lter drier and loss of charge switch. A eld
installed crankcase heater is standard on
S1H 09 &12 (Thermostatically controlled)
models, and is available as optional equip-
ment on other models.
• 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 lter 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)
• 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 (eld
installed kit)
• Low Ambient for operation down to 0º F
for S1C, S1H or S2C systems (consult
factory for availability)
INSTALLER SUPPLIED ITEMS
• Power wiring
• Low Volt wiring (18 awg minimum)
• Secure mounting pad or foundation
• Refrigerant piping (if not purchased
from EMI)
• High Volt Disconnect
• Refrigerant for charging interconnect
piping (see charge table on page 10)
ITEMS FOR CONSIDERATION
LowAmbient 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
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 efciency.

SYSTEM OPTIONS

ITEMS FOR CONSIDERATION
• Locate the unit as close to the indoor
section as possible. (See Tubing
Specications chart on pape 7.)
• If the unit is used for low ambient cool-
ing down to 32°F, this option must be
specied to prevent system damage.
• Avoid high trafc areas and prevailing
wind locations.
• Surface must be at and level.
• Mount unit above typical snow fall
levels.
Ensure free ow of air through the unit.
Air must not recirculate from discharge to
intake. Air is drawn through the coil and
side discharged through the fan grille. A
minimum48"clearance isnecessaryfor
the condenser discharge. Rear intake
(coil side) clearance is 12" minimum.
Consider how power will be run to the unit
from the power source. Refrigerant piping
should be a direct line to the indoor unit.
SITE PREPARATION
1. Place the unit on a at concrete surface
or pad if on the ground. Roof mounting
should use a build up platform to avoid
intake of hot air from the roof.
2.In areas of heavy snowfall, condens-
ers should be set above the level of
maximum anticipated snowfall (12"
is usually adequate).
1. Loosen the screws on left and right sides
of the front panel. (Do not remove these
screws.)
2. Remove the screws on the front of the
panel.
3. To remove front panel:
4.Slide front panel forward to clear side
screws and remove.

UNIT MOUNTING INSTRUCTIONS
Side discharge unit allows for per-
manent mounting through the feet. This is
highly recommendeddue to the vertical
design of the unit.
SYSTEM OPTIONS (cont.)
void the warranty. A Field Installed Low-
Ambient Kit is good for operation down to
32º F. This is accomplished by cycling the
condenser fan on and off, which will in turn
maintain a constant low side pressure pro-
viding a steady cooling effect and keeping
the air handler from frosting-up.

ELECTRICAL WIRING
1. All electrical wiring must be run accord-
ing to NEC and local codes.
2. Refer to the unit rating plate for voltage,
minimum circuit ampacity and over cur-
rent protection requirements.
b) The screws adjacent to the front
panel should already be loose (don't
remove them).
