APPLICATION and LOCATION

GENERAL

These instructions explain the recommended method to install the air cooled remote type condensing unit, the interconnecting refrigerant tubing and the electrical wiring connections to the unit.

The condensing units are to be used in conjunction with the matching evaporator coils or evaporator blower units for comfort cooling applications as shown in the specification sheet.

These instructions and any instructions packaged with any separate equipment required to make up the entire air conditioning system should be carefully read before beginning the installation. Note particularly “Starting Procedure” and any tags and/or labels attached to the equipment.

SHIPPING DAMAGE

Upon receipt of equipment, the carton should be checked for external signs of shipping damage. If damage is found, the receiving part must contact the last carrier immediately, preferably in writing, requesting inspection by the carrier’s agent.

APPLICATION

Size of unit for a proposed installation should be based on heat loss calculation and air duct sizing made according to methods of Air Conditioning Contractors of America. The air duct should be installed in accordance with the Standards of the National Fire Protection Association for the Installation of Air Conditioning and Ventilating Systems of Other Than Residence Type, NFPA 90A, and Residence Type Warm Air Heating and Air Conditioning Systems, NFPA 90B. Where local regulations are at a variance with instructions, installer should adhere to local codes.

FIGURE 2

INSTALLATION CLEARANCE

MIS-589

LOCATION

The condensing unit is designed to be located outside with free and unobstructed condenser air inlet and discharge. It must also permit access for service and installation.

Condenser air enters the coil from the rear of the unit as shown in Figure 2 with electrical service access.

MOUNTING UNIT OUTSIDE ON SLAB

A solid level base or platform, capable to support the unit’s weight, must be set at the outdoor unit predetermined location. The base should be at least two inches larger than the base dimensions of the unit and at least two inches higher than surrounding grade level. The required unit minimum installed clearances must be maintained as called out in Figure 2 when locating and setting the base.

Remove the unit from its shipping carton and position the unit on the prepared base or platform.

NOTE: These units employ internally sprung compressors; therefore, it is not necessary to remove or loosen the base mounting bolts on the compressor prior to operation.

Consideration should be given to the electrical and tubing connections when placing the unit to avoid unnecessary bends or length of material.

IMPORTANT INSTALLER NOTE

For improved start up performance, wash the indoor coil with a dishwashing detergent.

INSTALLATION REFRIGERANT TUBING

The information that follows on installing refrigerant tubing and for changing the system orifice (if required) covers applications listed in the front of this installation instruction only. Although other indoor units may be of similar construction, the installation instructions for these units should be consulted for proper installation of those units prior to installation.

This information is provided for the field service personnel to install refrigerant tubing in compliance with Section 608 of Title VI National Recycling and Emission Reduction Program for the U.S. Clean Air Act effective July 1, 1992.

Consult manual 2100-002 on procedure for leak test – evacuation – charging before installation refrigerant tubing that requires any refrigerant recovery or system evacuation. Manual 2100-002 is included with the unit installation instruction package when shipped from the factory.

Manual 2100-346

Page 4

FIGURE 3

INSTALLING REFRIGERANT TUBING

pp5

SWEAT STYLE TUBING CONNECTIONS: SWEAT INDOOR UNIT and SWEAT OUTDOOR UNIT

Use only refrigeration grade (dehydrated and sealed) copper tubing. Care must be taken to insure that the tubing is kept clean and dry before and during installation. Do not remove the plugs from the tubing ends, coil connections or base valves until the connection is ready to be brazed.

The suction line must be insulated with a minimum of 3/8” Armaflex or equivalent before cutting and making connections.

1.Being careful not to kink, route both the suction line and liquid line between the indoor unit and outdoor unit. Use a tubing bender to make any necessary bends in tubing. When necessary to bend the insulated tube suction line, cut the insulation around its circumference at a distance far enough beyond the point of the bend so as to clear the tubing bender. Slip the insulation back together and vapor seal the joint with tape. Coil any excess tubing in a horizontal place with the slope of the tubing toward the condensing unit. See Figure 3.

CAUTION

1. Be careful not to tear the insulation when pushing it through hole in masonry or frame walls. 2. When sealing the tube opening in house wall, use a soft material to prevent tube damage and vibration transmission. 3. Avoid excessive bending in any one place to avoid kinking.

2.The tubing ends should be cut square. Make sure it is round and free of burrs at the connecting ends. Clean the tubing to prevent contaminants from entering the system.

NOTE: Do not braze line to units! If orifice needs to be changed, change out orifice first.

If the orifice does not have to be changed, skip the instructions outlined further in Step 3 and proceed to Step 8.

3.Disassemble Flow Control Assembly by turning body hex.

4.If existing orifice has not dropped out of the body when disassembled, remove by using a pin or paper clip. Discard this original orifice.

5.Insert proper sized orifice fully into the flow control body with rounded “bullet” nose towards the unit as shown in Figure 4. Insure the orifice stays inserted in body before connecting mating half. See chart in the outdoor unit installation instructions for proper size.

CAUTION

Be sure there is no dirt introduced into the flow control - orifice assembly. Be sure to install the orifice with the bullet nose pointing in the proper direction as shown in Figure 4. Failure to do so will result in improper operation.

FIGURE 4

FLOW CONTROL ASSEMBLY

FIELD ORIFICE REPLACEMENT INSTRUCTIONS

6.Thread assembly halves together by hand to insure proper mating of threads and tighten until bodies “bottom” or a definite resistance is felt.

7.Using a marker pen or ink pen, mark a line lengthwise from the union nut to the bulkhead. Then tighten an additional 1/6 turn (or 1 hex flat). The misalignment of the line will show the amount the assembly has been tightened. This final 1/6 turn is necessary to insure the formation of the leakproof joint.

8.Wrap a wet rag around the copper stub before brazing.

9.Flux the copper tube and insert into the stub. Braze the joint using an alloy of silver or copper and phosphorus with a melting temperature above 1,100° F for copper to copper joints. The phosphorus will act as a flux, therefore, no flux will be required.

Manual 2100-346

Page 5

A copper-silver alloy with a high silver content should be used when iron or steel material is involved in the joint. These alloys require the use of silver solder flux. Alloys containing phosphorus should not be used with iron or steel. Phosphorus reacts with the iron forming iron phosphate which is extremely brittle.

CAUTION

1. Brazing alloys with a melting temperature below 700° F should not be used. 2. Leadtin or tin-antimony solders should not be used due to their low melting point and necessity for corrosive fluxes.

To further prevent the formation of copper oxide inside the tubing, dry nitrogen may be purged through the refrigerant system during brazing.

WARNING

Never purge or pressurize a system with oxygen. An explosion and fire will result.

10.After brazing, quench with wet rag to cool the joint and remove any flux residue.

11.Leak test all connections using an electronic leak detector or a halide torch.

12.Evacuate suction line, liquid line and indoor unit through outdoor unit base valves.

13.Open both the suction and liquid base valves to the fully open position. Refer to section later in installation instructions for details on setting proper system charge.

FIELD FABRICATED TUBING CONNECTIONS: QUICK CONNECT INDOOR UNIT and SWEAT OUTDOOR UNIT USING CTO KIT

Use only refrigeration grade (dehydrated and sealed) copper tubing. Care must be taken to insure that the tubing is kept clean and dry before and during installation. Do not remove the plugs from the tubing ends, coil connections or base valves until the connection is ready to be brazed.

The suction line must be insulated with a minimum of 3/8” Armaflex or equivalent before cutting and making connections.

1.Being careful not to kink, route both the suction line and liquid line between the indoor unit and outdoor unit. Use a tubing bender to make any necessary bends in tubing. When necessary to bend the insulated tube suction line, cut the insulation around its circumference at a distance far enough beyond the point of the bend so as to clear the tubing bender. Slip the insulation back together and vapor seal the joint with tape. Coil any excess tubing in a horizontal place with the slope of the tubing toward the condensing unit. See Figure 3.

CAUTION

1. Be careful not to tear the insulation when pushing it through hole in masonry or frame walls. 2. When sealing the tube opening in house wall, use a soft material to prevent tube damage and vibration transmission. 3. Avoid excessive bending in any one place to avoid kinking.

2.The tubing ends should be cut square. Make sure it is round and free of burrs at the connecting ends. Clean the tubing to prevent contaminants from entering the system.

NOTE: Do not make any tubing connection at indoor unit at this time. Make all brazing of joints and evacuate both suction and liquid line first.

3.Wrap a wet rag around the copper stub before brazing.

4.Flux the copper tube and insert into the stub. Braze the joint using an alloy of silver or copper and phosphorus with a melting temperature above 1,100° F for copper to copper joints. The phosphorus will act as a flux, therefore, no flux will be required.

A copper-silver alloy with a high silver content should be used when iron or steel material is involved in the joint. These alloys require the use of silver solder flux. Alloys containing phosphorus should not be used with iron or steel. Phosphorus reacts with the iron forming iron phosphate which is extremely brittle.

To further prevent the formation of copper oxide inside the tubing, dry nitrogen may be purged through the refrigerant system during brazing.

CAUTION

1. Brazing alloys with a melting temperature below 700° F should not be used. 2. Lead-tin or tin-antimony solders should not be used due to their low melting point and necessity for corrosive fluxes.

WARNING

Never purge or pressurize a system with oxygen. An explosion and fire will result.

5.After brazing, quench with wet rag to cool the joint and remove any flux residue.

6.Leak test all connections using an electronic leak detector or a halide torch.

7.Evacuate suction line and liquid line through outdoor unit base valves.

If orifice does not have to be changed, skip the instructions outlined further in Step 8 and proceed to Step 15.

8.Recover charge from the indoor unit.

A.Connect the suction line only to the indoor unit as outlined in Steps 15, 16, and 17.

B.Recover indoor unit and suction line unit charge through service port located on outdoor unit base valve.

9.Disassemble Flow Control Assembly by turning body hex.

10.If existing orifice has not dropped out of the body when disassembled, remove by using a pin or paper clip. Discard this original orifice.

11.Insert proper sized orifice fully into the flow control body with rounded “bullet” nose towards the unit as shown in Figure 4. Insure the orifice stays inserted in body before connecting mating half. See chart in the outdoor unit installation instructions for proper size.

CAUTION

Be sure there is no dirt introduced into the flow control – orifice assembly. Be sure to install the orifice with the bullet nose pointing in the proper direction as shown in Figure 4. Failure to do so will result in improper operation.

12.Thread assembly halves together by hand to insure proper mating of threads and tighten until bodies “bottom” or a definite resistance is felt.

13.Using a marker pen or ink pen, mark a line lengthwise from the union nut to the bulkhead. Then tighten an additional 1/6 turn (or 1 hex flat). The misalignment of the line will show the amount the assembly has been tightened. This final 1/6 turn is necessary to insure the formation of the leakproof joint.

14.Evacuate the suction line and indoor unit through the outdoor unit base valve before connecting all other tubing. Refer to section later in installation instructions for details on setting the proper refrigerant charge.

15.Remove (remaining) protector caps and plugs (if orifice was changed). Inspect fittings and if necessary carefully wipe coupling seats and threaded surfaces with a clean cloth to prevent the inclusion of dirt or any foreign material in the system.

Manual 2100-346

Page 7

16.Lubricate male half diaphragm and synthetic rubber seal with refrigerant oil. Thread coupling halves together by hand to insure proper mating of threads. Be sure to hold the coupling firmly to prevent movement of the coupling and tubing. Failure to do so could tear out the diaphragm causing a blockage of the system. Use proper size wrenches (on coupling body hex and on union nut) and tighten until coupling bodies ”bottom” or a definite resistance is felt.

CAUTION

After starting to tighten up the fitting, never try to back it off or take it apart.

17.Using a marker or ink pen, mark a line lengthwise from the coupling union nut to the bulkhead. Then tighten an additional 1/4 turn. The misalignment of the line will show the amount the coupling has been tightened. This final 1/4 turn is necessary to insure the formation of leakproof joint. If a torque wrench is used, the torque values shown in Table 5 are recommended.

18.Leak test all connections using an electronic leak detector or a halide torch.

19.When tubing is installed in attics or drop ceilings, insulate the couplings on the larger tube thoroughly with 3/8” wall thickness, closed cell sponge tube insulation or equivalent. Failure to insulate will result in water damage to ceiling since the fitting will “sweat” and drop water on the ceiling.

WIRING INSTRUCTIONS

GENERAL

All wiring must be installed in accordance with the National Electrical Code and local codes. In Canada, all wiring must be installed in accordance with the Canadian Electrical Code and in accordance with the regulations of the authorities having jurisdiction. Power supply voltage must conform to the voltage shown on the unit serial plate. A wiring diagram of the unit is attached to the inside of the electrical cover. The power supply shall be sized and fused according to the specification supplied. A ground lug is supplied in the control compartment for equipment ground.

The unit rating plate lists a “Maximum Time Delay Fuse” or HACR type” circuit breaker that is to be used with the equipment. The correct size must be used for proper circuit protection and also to assure that there will be no nuisance tripping due to the momentary high starting current of the compressor motor.

CONTROL CIRCUIT WIRING

For split systems, the minimum control circuit wiring gauge needed to insure proper operation of all controls in both indoor and outdoor units will depend on two factors:

1.The rated VA of the control circuit transformer.

2.The maximum total distance of the control circuit wiring. (This is the distance between the wall thermostat to the indoor unit plus the distance between the indoor unit to the outdoor unit.)

The following table should be used to determine proper gauge of control circuit wiring required.

2.Maximum total distance of control circuit wiring 85 feet.

From Table 6, minimum of 18 gauge wire should be used in the control circuit wiring.

For control circuit transformers rated other than those listed, use the next lower rated transformer listed.

Example: 1. Control circuit transformer rated at 55 VA

From table use 50VA transformer.

There are two (2) separate control diagrams for fossil fuel furnaces with air conditioners.

SERVICE

SERVICE HINTS

1.Caution homeowner to maintain clean air filters at all times. Also, not to needlessly close off supply and return air registers. This reduces air flow through the system, which shortens equipment service life, as well as, increasing operating costs.

2.Check all power fuses or circuit breakers to be sure that they are the correct rating.

3.Periodic cleaning of the outdoor coil to permit full and unrestricted air flow circulation is essential.

FAN BLADE SETTING DIMENSIONS

Shown in Figure 10 are the correct fan blade setting dimensions for proper air delivery across the outdoor coil.

Any service work requiring removal or adjustment in the fan and/or motor area will require that the dimensions below be checked and blade adjusted in or out on the motor shaft accordingly.
