–

–

Solid-core fi lter drier

Thermostatically-controlled crankcase heater (heat pump only) and 24,000 (22) Btuh capacity condensing units will provide cooling and heating for two air handlers, as identifi ed on page 36 .

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 simplifi ed by a 24v control interconnection from the air handler.

Multiple units can be lined up in close proximity to an exterior wall.

Service valves are recessed to reduce tampering.

All 9,000-12,000 Btuh units are equipped with a Duratec Performance Package that includes an oversized suction accumula-

Thermostatically-controlled crankcase heater

• This feature energizes the crankcase heater only when needed, saving unnecessary power usage and increasing overall

• management and a factory-installed solid core fi lter 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.

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°F.

This is accomplished by cycling the condenser fan on and off. This will, in turn, maintain a constant low-side pressure, providing a steady cooling eff ect and keeping the air handler from frosting-up.

Mounting the Unit

•

•

Before installing, consider:

•

•

•

Locate the unit as close to the indoor section as possible. (see page 11 .)

S1CG/S2CG — If the unit is used for low ambient cooling down to 32°F, S1CG/

S2CG require CCH.

Avoid high traffic areas and prevailing wind locations.

Surface must be fl at and level.

Mount unit above typical snow fall level.

This is particularly important for heat pump applications (S1HG/S2HG).

2. 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.

NOTICE

•

•

•

•

•

•

Ensure free fl 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 minimum 48” clearance is necessary for 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.

mounting through the feet. This is highly recommended due to the vertical design of the unit.

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.


Slide front panel forward to clear side screws and remove.


Insert lag bolts through the holes in the bott om of the unit and tighten to secure.


Insert lag bolts through the holes in the feet on the back of the unit and tighten to secure.

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

Site preparation

1. Place the unit on a fl at concrete surface or pad if on the ground. Roof mounting should use a built up platform to avoid intake of hot air from the roof.

Electrical Wiring

NOTICE

All electrical wiring must be run according to NEC and local codes.

1. Figure 5, Page 8 — Refer to the unit rating plate for voltage, minimum circuit ampacity and over current protection requirements.

2. Use only HACR type breakers or time delay fuses. Select the wire size according to the ampacity rating.

•

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 air handler, the P-trap will help the return of oil back to the compressor.

CAUTION

It is recommended that a

be installed in the liquid line, at the indoor unit on models without a factory-installed fi lter drier (i.e. 18K and larger).

A prefabricated trap may be purchased from a wholesaler or distributor however the trap should be shallow as with the (3) elbow confi guration.

Each elbow is approximately 2 equivalent feet.

One P-trap is equal to approximately

12 equivalent feet.

P-traps are not required at the foot of the hot gas risers due to increased oil fl ow at higher temperatures.

CAUTION

• Avoid piping on wet and rainy days.

• Use only clean, refrigeration-grade copper tubing.

• Use tubing benders to guard against kinking.

• Be certain no burrs remain on the fi tt ings.

• Cap ends of lines until ready for connections.

• Be certain that plastic end caps remain in place when inserting through wall openings.

• Insulate the suction line.

• Isolate tubing from transmitt ing vibration to the building or unit and avoid contact with sharp edges.

• Wrap refrigeration valves with a wet rag “heat sink” to protect valves while brazing. (See Figure 16, Page 12 .)

Charging the unit

1. Att ach manifold set, vacuum pump, &

Micron Gauge. ( Figure 18 ).

2. Evacuate line to 500 microns or less to ensure all moisture has been removed and there are no leaks (Figure 19).

3. Once certain of a good evacuation and leak free joints, back-seat the valves

(counter-clockwise) to open and allow factory charge to fi ll lines and indoor unit

(Figure 20, pg. 13).

WARNING

It is illegal to discharge refrigerant into the atmosphere. Use proper reclaiming methods & equipment when installing or servicing this unit.

The units are delivered pre-charged with refrigerant for the condenser coil and the air handler. Charging of the fi eld installed piping is required. Refer to the refrigerant charge table for the proper amount to be added for the applications interconnect piping. Unit service valves are solid brass, for sweat connections.

CAUTION

Pressure test

all fi eld installed piping with nitrogen. Using a suitable vacuum pump, evacuate the tubing and indoor unit to 500 microns or less, with service valves remaining front seated (closed).

Before releasing the refrigerant from the condenser, be sure the manifold gauge set is closed so as not to lose vacuum when shutt ing down the pump.

Release refrigerant from the condensing unit by back seating the service valve. Allen wrenches are used to open the valve.

Replace valve caps. DO NOT back seat the valves past the snap fl anges that hold the valve core in place.

If the condenser coil is heavily frosted up with ice, it is likely that the “Defrost

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 heating mode. When testing is complete be sure to remove the jumper(s). DO NOT leave the unit in test mode with jumper(s) in place.
