Product description

The AmericaSeries S1CG/S1HG and S2CG/
S2HG condensing units are air-cooled, vertically-arranged side-discharge,high-efficiency
units designed specifically to meet or exceed
a 13 SEER rating.
The S1CG Models 09-36 and S 1HG Models
09-24 condensing units will provide cooling
and heating for a single evaporator, as identified on page 32 and page 33.
The S2CG/S2HG 18,000 (99), 21,000 (92)
and 24,000 (22) Btuh capacity condensing
units will provide cooling and heating for two
evaporators, as identified on page 34.

This feature energizes the crankcase
heater only when needed, saving unnecessarypower usage and increasing overall
system efficiency.

Installation of the S1CG/S1HG and
S2CG/S2HG condensing units is simplified by a 24v control interconnection
from the evaporator.
Multiple units can be lined up in close
proximity to an exterior wall.
Service valves are recessed to reduce
tampering.
All9,000-12,000 Btuh units are equipped
with a Duratec Performance Package that
includes an oversized suction accumulator with surge baffles and enhanced oil
management and a factory-installed solid
core filter drier.
A factory-installed crankcase heater is
standard on S1HG 09 &12 (thermostatically controlled) and S2HG models, and
is available as optional equipment on
other models.

Before installing,
•
•

•
•
•

consider:

Locate the unit as close to the indoor section as possible. (see page 11.)
S 1CG/S2CG -- If the unit is used for low
ambient cooling down to 32°E S1CG/
S2CG require CCH.
Avoid high traffic areas and prevailing
wind locations.
Surface must be fiat and level.

In areas of heavy snowfall, condensers
should be set above the maximum anticipated snow line (12" is usually adequate
for most locations).

Unit Mounting

Instructions

Model S1CG is shown for example in the
following sequence.
The side- discharge unit allows forpermanent
mounting through the feet. This is highly
recommended due to the vertical design of
the unit.

Mount unit above typical snow fall level.
This is particularly important for heat
pump applications (S 1HG/S2HG).

1. Figure 1, Page 7:
- Bullet 1 -- Loosen the screws on left
and right sides of the front panel. (Do
not remove these screws.)
- Bullet 2 -- Remove the screws on the
front of the panel.
2. Figure 2, Page 7:
Slide front panel forward to clear side
screws and remove.
3. Figure 3, Page 7:
Insert lag bolts through the holes in the
bottom of the unit and tighten to secure.
4. Figure 4, Page 7:
Insert lag bolts through the holes in the
feet on the back of the unit and tighten
to secure.
5.

Site preparation

Replace the front panel, do not tighten
the side screws at this time.

Place the unit on a flat concrete surface
or pad if on the ground. Roof mounting
should use a build up platform to avoid
intake of hot air from the roofi

to the ampacity rating.
3. To access electrical connections and wiring diagram:

Tubing specifications

•
The system will support refrigerant runs to
the inside unit as listed in Table 1, Page 11.
The units are furnished with sweat connections and are equipped with refrigerant valves
and Schrader fittings for charging and taking
pressure readings.

•

A P-trap is recommended when the
suction riser is equal to or greater than
show in Figure 14, Page 11 and Table 1,
Page 11.
When the condenser is installed above the
evaporator, the P-trap will help the return
of oil back to the compressor.

Charge to proper weight, charge based
on feet of interconnect (see tables on
page 15). Only add/remove 410A in
liquid form.

Refer to charts beginning on page 17 to
"fine tune" the refrigerant charge to meet
your conditions.

M1 systems require field charge adjustments. Refer to the "Refrigerant Charge
Tables" for proper weight charge and
to the supplied "Single-zone Operation

of the
indoor section or room thermostat.
Therefore,
the system operation
will be described
in the
manual pertaining
to the indoor section.

EMI units are designed and constructed
for reliability and long life with minimal
maintenance. You can assure peak operating
efficiency by regularly inspecting for free air
passage into and through the coil. If debris
collects on the air coil, it should be cleaned
by "back-flushing" with a spray of water or
vacuuming.
TURN OFF POWER SUPPLY
FIRST. Outdoor units may be cleaned or
waxed if desired. Use a non-abrasive car wax
(on metal surfaces only).

Operation Charts (supplied on previous
pages).

Before leaving
Remove gauge set. Mount all access panels
and make sure they are properly secured.

This unit is equipped with a permanently

EMI AmericaSeries condensers are designed
to operate with EMI AmericaSeries evaporators. Both the condenser (outdoor unit) and
evaporator (indoor unit) have a high volt service connection. Each is to be independently
connected to the electrical service panel. (See
the unit name plate for the correct breaker
type and size). The outdoor and indoor units
are also connected to each other through a low
volt interconnect wiring. A 24v transformer
located in the indoor unit provides the low volt
power source.

reversing valvewill energize (R & O heat pumps
only) along with the compressor and outdoor
fan (R & Y). When the indoor control is satisfied and the room temperature falls below the
set temperature, the compressor and fan will
de-energize. The anti-short cycle timer (ASCT)
will prevent the compressor from re-starting for
three minutes.
Heating operation
Heating operation requires that the control
(either unit mount or remote wall mount, heat
pump thermostat) make a connection between
low-Volt terminals "R" and "Y" only. When the
indoor control is placed in heating mode, with
the set point temperature above room temperature, the compressor and outdoor fan (R
& Y) will energize. When the indoor control is
satisfied and the room temperature rises above
the set temperature, the compressor and fanwill
de-energize. The anti-short cycle timer (ASCT)
will prevent the compressor from re-starting for
three minutes.

Straight cool condensers are designed to operate as a single stage cooling unit. Heat pump
condensers are designed to operate as a single
stage cooling two stage heating unit. For proper
operation the unit must be matchedwith an appropriate EMI indoor unit with unit mounted
controls and/or wall mounted thermostat. For
two-stage heating operation the indoor unit
must be equipped with an electric strip heater.

24v, low-volt control power to the

across low-volt terminals "R" and "C".

The defrost control circuit is designed to keep
the condenser coil free from frost and ice during
heatingmode. This is accomplished through the
precise switching sequence of the outdoor fan,
reversing valve and indoor auxiliary heater.

Heat pump condensers utilize areversing valve
to provide reverse cycle operation. Therefore
the outdoor unit will act as either a condenser
or an evaporator there-by providing comfort
cooling or heating to the indoor space. The
reversing valve is energized in cooling. Should
the valve fail to actuate, the system will default
to the heating mode of operation.
