GENERAL
These installation instructions cover the 30HK, HL, HWA, HWB, HWC, and HWS units. The HL and HWA are condenserless units, and the HK, HWB, HWC, and HWS units are all ¯uid cooled. In addition, the 30HK and HWC units have a standard mechanically cleanable condenser and the 30HWS unit has a mechanically cleanable condenser speci®cally designed for sea coast applications.
SAFETY CONSIDERATIONS
Installing, starting up, and servicing this equipment (Fig. 1-3) can be hazardous due to system pressures, electrical components, and equipment location (roofs, elevated structures, etc.).
Only trained, quali®ed installers and service technicians should install, start up, and service this equipment.
When working on the equipment, observe precautions in the literature and on tags, stickers, and labels attached to the equipment.
·Follow all safety codes.
·Wear safety glasses and work gloves.
·Use care in handling, rigging, and setting bulky
equipment. |

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 dimensional 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 connections 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 operating weight (see Tables 1A-2B and Fig. 9 and 10). If necessary, 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 damage or missing parts. If damaged, or if shipment is incomplete, ®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 bringing 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 basement 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 installation is level. Refer to Fig. 4 and 5 for space requirements 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, remove the skid (from units not equipped with factorymounted wheels), or remove the wheels (if equipped). Remove 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 isolators, follow the mounting instructions included with the accessory vibration isolator (Carrier part numbers 30HW900001 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.

Step 5 Ð Make Piping Connections Ð See Fig. 13 and 14 for typical piping applications.
30HK, HWC, HWS CONDENSER DESCRIPTION Ð All 30HWC and HWS units use a shell-and-tube condenser with removable heads for easy tube servicing. Refrigerant is contained within the shell, and water ¯ows through the tubes. The 30HK and HWC units use a steel shell condenser(s) with steel tube sheets and copper tubes. The 30HWS units are designed for sea coast applications and use a steel shell condenser with cupronickel tube sheets and tubes. In addition, the 30HWS water heads utilize ``sacri®cial'' zinc anodes for condenser corrosion protection.
IMPORTANT: Inspect the zinc anodes every 3 months for deterioration and replace as needed. Galvanic protection of the condenser is lost if the anodes are not replaced prior to complete deterioration.
The number of tubes in the condenser(s) varies depending on the unit size. The condensers have internal subcoolers which provide approximately 8 F (4.4 C) for 30HK, HL units or 13 F (7.2 C) for 30HW units subcooling at ARI (Air Conditioning and Refrigeration Institute, U.S.A.) rating conditions.
30HL, HWA SYSTEM CONDENSER Ð For detailed condenser piping installation instructions for 30HL and HWA systems, refer to separate instructions packaged with the remote condenser unit(s).
Condenser refrigerant piping for 30HL and HWA units should be sized to minimize the amount of refrigerant required.
The 30HL and HWA units that use an air-cooled evaporative condenser(s) must have adequate means for head pressure control when operating below 60 F (15.6 C).
Carrier recommends that a ®eld-supplied pressure relief device be installed after the muffler in each discharge line. Most local codes require the relief valve to be vented directly to the outdoors. The vent must not be smaller than the relief valve outlet.
30HWB CONDENSER DESCRIPTION Ð All 30HWB units use a brazed-plate heat-exchanger-type condenser. These heat exchangers are made of embossed plates of acid-resistant stainless steel. Every other plate is reversed so that the ridges of the herringbone pattern intersect one another on adjacent plates, forming a lattice of contact points. These plates are vacuumbrazed together to form a compact and pressure-resistant heat exchanger.
After brazing, the impressions in the plates form 2 separate systems of channels where the refrigerant and water flows are counter-current. The number of plates varies depending on unit tonnage. The condensers provide approximately 14° to 18° F (8° to 10° C) liquid subcooling at the standard Air Conditioning and Refrigeration Institute (ARI) rating condition.
30HK, HWC, HWS CONDENSER(S) Ð When facing the front of the unit, the condenser(s) is in the uninsulated shell(s) located across the bottom of the unit. The water connections are such that the water inlet is located on the left-hand side (30HK) or right-hand side (30HW) of the unit. The water inlet must ALWAYS be on the bottom of the condenser(s) to provide the proper subcooling. The water outlet is located on the right-hand side (30HK) or left-hand side (30HW) of the unit. The water connections can be reversed by rotating the heads and gaskets 180 degrees ON BOTH ENDS OF THE CONDENSER(S).
IMPORTANT: THE WATER INLET MUST ALWAYS BE ON THE CONDENSER HEAD(S) THAT HAS THE NOZZLE CONNECTION AT THE BOTTOM OF THE HEAD. Incorrect inlet connection will result in poor system performance due to incorrect subcooling.
The LIQUID-IN and LIQUID-OUT labels indicate water connections AS SUPPLIED FROM THE FACTORY.
It is recommended that strainer with a minimum of 20 mesh be installed ahead of the condenser water inlet(s) to prevent debris from clogging or damaging the heat exchanger(s).
There is a pressure-relief device on the condenser(s) of all 30HK, HWC, and HWS units. Most local codes require that this relief be vented directly to the outdoors.
NOTE: The relief line must not be smaller than the relief valve outlet. Be sure to provide a way of draining and servicing the unit.
