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 fluid cooled. In addition, the 30HK and HWC units
have a standard mechanically cleanable condenser and the
30HWS unit has a mechanically cleanable condenser spe­cifically 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, qualified 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.

Be sure all power to equipment is shut off before per­forming maintenance or service. There may be more than
one disconnect. Tag all disconnects to alert others not to
turn on power until work is completed.

INSTALLATION

Location—

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 7
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 fluid 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 fluid 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 fluid connections to cooler and water con­nections to condenser,accessing the TXV, and replacing heat
exchanger(s) if necessary. See Fig. 8.

The floor 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 floor to transfer weight to nearest beams.

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

Sound enclosure — 75 lb (34 kg)

Hot gas bypass — 15 lb (7 kg)

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

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

200-amp non-fused disconnect — 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.

Do not store units in an area exposed to weather

Step 1 — Inspect Shipment — Inspectunit for dam-

age or missing parts. If damaged, or if shipment is incom­plete, file a claim immediately with the shipping company.

Step 2 — Rig and Place Unit

30HK,HL UNITS — 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 final 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 final
location per installation instructions provided with the
accessory.

Units Equipped WithFactory-Installed Unit Wheels —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 final location.

NOTE: The wheels are equipped with a thumb-screw brake.
Units Not Equipped With Factory-Installed Unit Wheels —

Do not remove the skid until the unit has been moved to its
final location. The unit may be moved by means of rollers
under the skid, a forklift truck, or rig and slings.

Step 3 — Place the Unit

30HK,HL UNITS — When unit is in final position, remove
skid, level the unit (using a level), and bolt the unit to floor
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 floor. However, if it is necessary to
locate the unit on an upper floor, be sure the structure has
been designed to support the unit weight. If necessary, add
structural support to floor. 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 fluid connections for cooler are required for
30HK installation. Installation of 30HL units varies only in
field piping required for the remote condenser.

30HW UNITS — When the unit is in its final position, re­move the skid (from units not equipped with factory­mounted wheels), or remove the wheels (if equipped). Re-

3

⁄8-in. wheel nuts to remove wheels from unit legs.

move
Level the unit (using a level), and bolt the unit to the floor
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 — Check Compressor Mounting and
Connections—

by special self-locking nuts (Fig. 12). After unit is installed,
loosen the self-locking nuts one at a time until compressor
floats freely. Do not remove nuts, as they are self-locking
and will hold their locked position.

As shipped, the compressor is held down

Step 5 — Make Piping Connections — See

Fig. 13 and 14 for typical piping applications.
30HK, HWC, HWS CONDENSER DESCRIPTION — 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 flows 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 ‘‘sacrificial’’ 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 — 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 30HLandHWAunitsshould
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 field-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 —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) — 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 mustALWAYS 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.
