INSTALLATION

Complete Pre--installation Checks

1. Unpack Unit -- Store the indoor and outdoor units in the

original packaging until it is moved to the final site for installation.

2. Inspect Shipment -- Upon receipt of shipment, check the

indoor and outdoor units for damage. If there is any damage, forward claim papers directly to the transportation company. Manufacturer is not responsible for damage incurred in transit.

3. Inspect Parts Supplied With Units – Check all items

against parts list (see Table 1). If any items are missing, notify your distributor or Carrier office. To prevent loss or damage, leave all parts in original packages until installation.

Consider System Requirements

1. Consult local building codes and NEC for special installation requirements.

2. When deciding the location of the indoor and outdoor units, ensure that the piping run does not exceed the allowed distances listed in Table 3.

3. Make sure the indoor and outdoor units are easily accessible to electrical power.

4. Allow sufficient clearances for airflow, wiring, refrigerant piping, and servicing the unit. See Fig. 3 and Fig. 4.

5. Condensate piping can be directed through the inside wall to an approved drain or straight outside.

INSTALL INDOOR UNIT

Plan the installation carefully before you begin.

1. Select indoor unit location.

a. A location that can bear the weight of the unit.

b. Do not install indoor units near a direct source of heat

such as direct sunlight or a heating appliance.

c. Do not install units too close to humid conditions.

2. Install Mounting Plate The factory supplied mounting plate will look like one of the following depending on the size of the unit.

Rear Piping

Determine the pipe hole position using the mounting plate as a template. Drill a 2--1/2 inch (63.5 mm) diameter hole in the wall at

point A or B as shown in Fig. 12 or Fig. 13. Drill the hole at a slope so that the outside end is 1/2 inch (13 mm) lower than inside end to ensure optimal drainage. Refer to Fig. 14.

Side Or Bottom Piping

Remove the knockout in the unit and drill a 2--1/2 inch (63.5 mm) hole where the pipe penetrates the structure using the guides given above.

INSTALL OUTDOOR UNIT

The outdoor units can be installed on the ground, on the roof, or mounted on a wall.

NOTE: Install the unit so that the coil does not face into prevailing winds. If this is not possible and constant wind winds above 25 mph are expected, use accessory wind baffle. See installation instructions provided with accessory kit. Wind baffles should also be used on all units with accessory low ambient temperature control.

Mounting on Ground

1. Mount unit on a solid level concrete pad.

2. If a heat pump is being installed, use a field-- provided snow stand or ice rack where prolonged subfreezing temperatures or heavy snow occurs.

3. Position unit so water or ice from roof does not fall directly onto unit.

4. On cooling only units, an accessory stacking kit can be used when units are to be stacked. See installation instructions provided with the accessory kit.

PERSONAL INJURY AND/OR EQUIPMENT DAMAGE HAZARD

Failure to follow this caution may result in personal injury and / or equipment damage. Be sure unit panels are securely in place prior to rigging.

1. Rig the unit. Keep the unit upright and lift using a sling. Use cardboard or padding under the sling, and spreader bars to prevent sling damage to the unit. See Fig 16. See Fig. 2 for center of gravity reference

2. Mount unit on a solid concrete pad or platform.

3. Isolate unit and piping from structure

4. If a heat pump is being installed, use a field-- provided snow stand or ice rack where prolonged subfreezing temperatures or heavy snow occurs.

5. On cooling only units, an accessory stacking kit can be used when units are to be stacked. See installation instructions provided with accessory kit.

Mounting Unit on Wall

The units can also be mounted on the wall using the accessory mounting kit.

Complete Outdoor Refrigerant Piping Connections

Follow the following general guidelines:

1. Use refrigerant grade field – supplied tubing. Refer to Table 4 for the correct line sizes.

2. Do not use less than 10 ft (93.05 m) of interconnecting tubing.

38HDF Units:

1. Assemble the connector tube to the factory supplied filter drier by:

a. Braze the field supplied connector to the inlet of the

filter drier (see Fig. 17)

b. Braze the factory supplied flare connector to the outlet

end of the filter drier (see Fig.17)

UNIT DAMAGE HAZARD

Failure to follow this caution may result in equipment damage or improper operation.

If any section of pipe is buried, there must be a 6 in. (152.4 mm) vertical rise to the valve connections on the outdoor unit. If more than the recommended length is buried, refrigerant may migrate to cooler, buried section during extended periods of system shutdown. This causes refrigerant slugging and could possibly damage the compressor at start--up.

When more than 80 ft (24.4 m) of interconnecting tubing is used, consult the Duct--Free Split System Long Line Application Guide for required accessories.

3. Insulate both lines. A minimum of 1/2 inch foam pipe insulation is recommended.

4. Run the refrigerant tubes as directly as possible and avoid unnecessary turns and bends.

5. Suspend refrigerant tubes to avoid damage to insulation or tubes so they do not transmit vibration to the structure.

6. When passing refrigerant tubes through the wall, seal the opening so rain and insects do not enter the structure. Leave some slack in refrigerant tubes between structure and outdoor unit to absorb vibration.

NOTE: A fusible plug is located in unit suction line; do not cap this plug. If local codes require additional safety devices, install as directed.

CAUTION

2. Assemble the Accurator body (see Fig. 18) using the correct factory supplied piston (refer to Table 7) .

NOTE: Arrow on AccuRater body points in free flow direction, away from the indoor coil.

3. Attach the complete Accurator assembly to the flare connection end of the filter drier

4. Braze the completed filter drier/Accurator assembly to the liquid service valve.

5. Connect the field supplied line set to the filter drier/Accurator assembly and the suction valve. A sweat connection is required at the suction valve and flareconnection is required for the mixed phase line.

6. Insulate any exposed areas between the line set and the liquid valve.

UNIT DAMAGE HAZARD

Failure to follow this caution may result in equipment damage or improper operation.

To prevent damage to unit or service valves observe the following:

S A brazing shield MUST be used. S Wrap service valves with wet cloth or use a heat sink

material.
