INSTALLATION

Location Ð Do not store units in an area exposed to weather because of sensitive control mechanisms and electronic devices. Locate unit indoors. See Fig. 4-8 for unit dimen- sional details.

Allow 36 in. (914 mm) in front of the unit for control box access door. Compressor can be removed from either side or the front of the unit. Prior to installation determine which direction compressor will be removed, and leave 3 to 4 ft (914 to 1219 mm) clearance for removal.

On 30HK,HL units leave 71¤2 ft (2.3 m) (for 040 units) or

9 ft (2.7 m) (for 050,060 units) clearance on one side for cooler tube removal. Leave 2 ft (610 mm) clearance on the other side for making ¯uid connections to cooler and water connections to condenser. See Fig. 4 and 5.

On 30HWA,B units, leave 2 ft (610 mm) on one side for making ¯uid connections to cooler and water connections to condenser, accessing the thermostatic expansion valve (TXV), and replacing heat exchanger(s) if necessary. See Fig. 6 and 7.

On 30HWC,S units, leave 75 in. (1905 mm) on one side for condenser tube removal and 2 ft (610 mm) on the other side for making ¯uid connections to cooler and water con- nections to condenser, accessing the TXV, and replacing heat exchanger(s) if necessary. See Fig. 8.

The ¯oor must be strong enough to support the unit op- erating weight (see Tables 1A-2B and Fig. 9 and 10). If nec- essary, add a supporting structure (steel beams or reinforced concrete slabs) to the ¯oor to transfer weight to nearest beams.

Additional weights of factory-installed options (30HW only) are:

Sound enclosure Ð 75 lb (34 kg) Hot gas bypass Ð 15 lb (7 kg)

80-amp non-fused disconnect Ð 15 lb (6.8 kg)

100-amp non-fused disconnect Ð 25 lb (11.3 kg)

200-amp non-fused disconnect Ð 70 lb (31.8 kg)

Be sure interconnecting piping and electrical conduits are suspended freely, and are not in contact with any adjacent walls. Be sure unit capillaries are not rubbing against anything.

Step 1 Ð Inspect Shipment Ð Inspect unit for dam- age or missing parts. If damaged, or if shipment is incom- plete, ®le a claim immediately with the shipping company.

Step 2 Ð Rig and Place Unit

30HK,HL UNITS Ð On each end of cooler, a steel loop is provided for the preferred method of lifting unit. Use spreader bars to keep cables away from compressor enclosure and control box. If unit is to be moved by forklift truck, use one of the following two methods:

1.From front or rear, lift under the cooler rails. Unit can be either on or off skid.

2.When moving from the ends, leave unit on the skid. Lift from under the skid.

If unit is to be dragged into ®nal position, or moved on rollers, it is recommended that it be left on the skid. When dragging or rolling, apply force only to the skid, not to the unit. Lift from above, using the lifting angles provided, to remove unit from the skid.

30HW UNITS

NOTE: If accessory mobility package (Carrier part no. 30HW900008) is to be used, install this accessory after bring- ing unit into building and before moving the unit to its ®nal location per installation instructions provided with the accessory.

Units Equipped With Factory-Installed Unit Wheels Ð This factory-installed option consists of 4 swivel-type wheels mounted to the legs of the unit. See Fig. 11. For units equipped with this option, leave the skid on until the unit is in the building. Once in the building, remove the skid, and wheel the unit to its ®nal location.

NOTE: The wheels are equipped with a thumb-screw brake.

Units Not Equipped With Factory-Installed Unit Wheels Ð Do not remove the skid until the unit has been moved to its ®nal location. The unit may be moved by means of rollers under the skid, a forklift truck, or rig and slings.

Step 3 Ð Place the Unit

30HK,HL UNITS Ð When unit is in ®nal position, remove skid, level the unit (using a level), and bolt the unit to ¯oor or pad.

NOTE: These units are not suitable for unprotected outdoor use.

Carrier recommends that these units be located in the base- ment or on the ground ¯oor. However, if it is necessary to locate the unit on an upper ¯oor, be sure the structure has been designed to support the unit weight. If necessary, add structural support to ¯oor. Also, be sure the surface for in- stallation is level. Refer to Fig. 4 and 5 for space require- ments and Fig. 9 for weight distribution.

Only electrical power connections, water connections for condenser, and ¯uid connections for cooler are required for 30HK installation. Installation of 30HL units varies only in ®eld piping required for the remote condenser.

30HW UNITS Ð When the unit is in its ®nal position, re- move the skid (from units not equipped with factory- mounted wheels), or remove the wheels (if equipped). Re- move 3¤8-in. wheel nuts to remove wheels from unit legs. Level the unit (using a level), and bolt the unit to the ¯oor or pad.

If unit is to be mounted on unit external vibration isola- tors, follow the mounting instructions included with the ac- cessory vibration isolator (Carrier part numbers 30HW900- 001 and -002).

Step 4 Ð Check Compressor Mounting and Connections Ð As shipped, the compressor is held down by special self-locking nuts (Fig. 12). After unit is installed, loosen the self-locking nuts one at a time until compressor ¯oats freely. Do not remove nuts, as they are self-locking and will hold their locked position.
