Product description

TheAmericaSeries S1CG/S1HG and S2CG/

S2HG condensing units are air-cooled,verti-

cally-arranged side-discharge,high-efficiency

units designed specifically to meet or exceed

a 13 SEER rating.

The S1CG Models 09-36 and S1HG Models

09-24 condensing units will provide cooling

and heating for a single evaporator, as identi-

fied 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.

The S1CG/S1HG and S2CG/S2HG are

quiet units that can be recommended for both

commercial and residential applications.

Features

• Installation of the S1CG/S1HG and

S2CG/S2HG condensing units is sim-

plified 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 aDuratec Performance Packagethat

includes an oversized suction accumula-

tor with surge baffles and enhanced oil

management and afactory-installed solid

core filter drier.

• A factory-installed crankcase heater is

standard on S1HG 09 &12 (thermostati-

cally controlled) and S2HG models, and

is available as optional equipment on

other models.

Controls and components

(Factory-installed or supplied)

• Compressor and fanmotor contactor

• Run capacitor

•Lowvoltage terminal connections

• H.P.S. (High pressure switch) with

manual external reset

• Heat pump hard start

• Cooling operation downto 32° Fstandard

on allunits

• Models 09-12 only:

System options

• Corrosion-resistant coil options (sea

coast and harsh environment usage):

- Copper fin/copper tube condenser

coil

- Coated aluminum fin/copper tube

condenser coil

•LowAmbient controls for cooling opera-

tion down to 0° F (standard equipment

can operate down to 32°F)

- Optional field-installed kit, when

specified, for cooling operation down

to O°F-- kit includes control, louvers .................

iiiiiiiiiiiiiiiii

and wind baffle plus installation

instructions

• Low Ambient controls for operation

down to 0° F (consult factory for avail-

ability)

• Models 09-12 only: iiiiiiiiiiiiiiiii

- 115v (single-zone only-- SICG or

S1HG)

- Field-installed thermostatically-con-

trolled crankcase heater for straight

cool units (S1CG or S2CG)

Installer-supplied items

• Power wiring

• LowVoltwiring (18 awgminimum)

• Secure mounting pad or foundation

• Refrigerant piping (ifnotpurchased from

EMI)

• High Volt Disconnect

• Refrigerant for charging interconnect pip-

ing (see charge table on page 15)

Low Ambient controls are required

when the system is asked to cool at

outdoor temperatures below 32 ° F, this

may cause damage to the compressor

and coil, and may void the warranty. A

field-installed low-ambient kit allows

operation down to 0° E

This is accomplished by cycling the

condenser fan on and off. This will,

in turn, maintain a constant low-side

pressure, providing asteady cooling

effect and keeping the air handler from

frosting-up.

The optional kits include louvers/wind

baffle, crankcase heater, and/or outdoor

fan cycling switch, and installation in-

structions.

_/N 240007754, Rev, A [05ff 509 5 Msd÷ i_ the USA

Before installing, consider:

•Locate the unit as close to the indoor sec-

tion 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.

• Mount unit above typical snow fall level.

This is particularly important for heat

pump applications (S 1HG/S2HG).

Site preparation

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

2. In areas of heavy snowfall, condensers

should be set above the maximum antici-

pated snow line (12" is usually adequate

for most locations).

Unit Mounting Instructions

Model S1CG is shown for example in the

following sequence.

Theside- discharge unit allows forpermanent

mounting through the feet. This is highly

recommended due to the vertical design of

the unit.

- Bullet 1 -- Loosen the screws on left

and right sides of the front panel. (Do

not remove these screws.)

- Bullet2 -- Remove the screws on the

front of the panel.

In low ambient cooling, ifa crankcase heater is

installed, power the system 24 hours before

attempting to start the unit in cool weather

(below 60 ° F).

Test unit data sheet

After doing a final system check using the

Operation Charts (supplied on previous

pages).

Record results on Test Unit Data Sheet on

page 36.

Before leaving

Remove gauge set. Mount all access panels

and make sure they areproperly secured.

Make final visual inspection and repair any

deficiencies.

A hard start kit may be required for units

in low voltage applications.

The S 1CG/S 1HG and S2CG/S2HG outdoor

sections are the compressor bearing units of

the system. It operates at the command 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).

This unit is equipped with a permanently

lubricated motor. Mthough oiling is not nec-

essary; adding a few drops through the oiling

ports twice yearly will extend the life of the

motor. Do not over oil.

Panels should remain on the unit at all times.

Service should be performed by a qualified

service agency only.

Specific changes

All EMI products are subject to ongoing

development programs so design and speci-

fications may change without notice. Please

consult the factory for more information.

EMI AmericaSeries condensers are designed

to operate with EMI AmericaSeries evapora-

tors. Both the condenser (outdoor unit) and

evaporator (indoor unit) have a high volt ser-

vice 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.

Straight cool condensers are designed to oper-

ate 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 ap-

propriate 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.

iiiiiiiiiiiiiiiiiiiiiiiii!i!i!!i240004180orasuitable24v, twostage

heating, heat pump thermostat.

Condenser operation

The transformer located in the indoor unit

provides 24v, low-volt control power to the

condenser (outdoor unit). This canbemeasured

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

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.

Cooling operation, single- and dual-zone

Cooling operation requires that the control

(either unit mount or remote wall mount ther-

mostat) make a connection between low-volt

terminals "R" and "Y" along with "R" and "O"

(heat pumps only). When the indoor control

is placed in cooling mode, with the set point

temperature below the room temperature, the

reversing valvewill energize (R & O heat pumps

only) along with the compressor and outdoor

fan (R & Y). When the indoor control is satis-

fied 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 tem-

perature, 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.

Defrost controls with short cycle

protection (heat pumps only}

The unit is equipped with a logic control circuit

designed to keep system operating at peek ef-

ficiency. The 24v circuit provides control to

the indoor and outdoor systems including a

three minute, anti-short cycle timer (ASCT)

compressor protection.

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.

Defrost initiation

The defrost-sensor is located on either the end

plate or the return bend of the condenser coil.

A defrost cycle will initiate after the sensor

doses (approx. 30° F) and remains closed for

the length of time selected on the control board

(either 30, 60 or 90 minutes)*.

At the start of the defrost cycle, the revers-

ing valve will change from heating to cooling

mode. The condenser fan will also switch off

there-by allowing pressure and temperature

to rise within the condenser coil to melt off

any ice build-up. At the same time the unit will

switch on the indoor electric strip heater to

temper the cold air being discharged from the

evaporator unit. This will continue until either

the defrost-sensor opens (approx. 60 ° F) or a

10-minute maximum cycle time has elapsed.

Defrost times will vary depending on outdoor

temperature and moisture conditions. When

the defrost cycle is complete the unit will return

to normal heating operation.

result in injury or electric shock.

DFT TST R and DF2

Defrost operation can be initiated using the

test pins located on the circuit board of the

condensing unit. "Defrost test operation" will

be a time compressed version of the actual

defrost cycle.

With the system "off", using two small alligator

clips, jumper the following sets of test pins. "R

and DF2" and "DFT TST".

Defrost control board

Apply power to the indoor and outdoor units.

Place the indoor unit in heating mode with the

set point temperature well above room tem-

perature. This is to ensure that the condenser

will remain on during the entire defrost test

operation.

The condenser will operate in heating for ap-

proximately 20 seconds. At that point the unit

will enter defrost mode for approximately 2

seconds. During this time the condenser fan

will switch off, the reversing valve will energize

and the defrost board will energize the indoor

electric heat relay through the "W" terminal.

After the two second defrost cycle is complete,

the unit will switch back to heating operation

for another 20 seconds. This process will re-

peat until the jumpers are removed from the

test pins.

If the condenser coil is heavily frosted

up with ice, it is likely that the "Defrost

Sensor" is already closed. In this case the

"R and DFT" jumper can be eliminated.

To initiate defrost, momentarily jump

pins marked "DFT TST" until the defrost

cycle begins. The unit will remain in

defrost mode until the condenser coil is

defrosted and then it will return to heat-

ing mode. When testing is complete be

sure to remove the jumper(s). DO NOT

leave the unit in test mode with jumper (s)

Low ambient operation

Ifthe unit is equipped with low ambient fan con-

trol for cooling, the fan will remain off (while

in cooling mode) until the condenser pressure

reaches 340 psi. The fan will then energize and

run until the condenser pressure falls below

247 psi. This will happen only in the cooling

mo de (or when the reversing valve is energized).

In heating (reversing valve not energized), the

fan will run continuous so long as the connec-

tion is made between "R" and "Y".
