WARNING

Electrical shock can cause personal injury and death. Shut
off all power to this equipment during installation. There
may be more than one disconnect switch. Tag all discon­nect locations to alert others not to restore power until work
is completed.

GENERAL

These installation instructions cover the 30MPA, MPW units

with ComfortLink controls. The 30MPA units are condenserless
units and the 30MPW units are all fluid cooled.

SAFETY CONSIDERATIONS

Installing, starting up, and servicing this equipment (Fig. 1

and 2) can be hazardous due to system pressures, electrical
components, and equipment location (roofs, elevated struc­tures, etc.). Model number structure is shown in Fig. 3.

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.

Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

Location —

er because of sensitive control mechanisms and electronic
devices. Locate unit indoors. See Fig. 4 and 5 for unit dimen­sional details.

When considering location, consult National Electrical
Code (NEC) and local code requirements. Allow sufficient
space for wiring, piping, and service. Install unit in an area
where it will not be exposed to ambient temperatures below
50 F (10 C).

Allow 36 in. (914 mm) in front of the unit for control box
access door. Additional clearance may be required per local
codes. Prior to installation determine which direction compres­sor will be removed, and leave 3 to 4 ft (914 to 1219 mm)
clearance for removal.

On all units leave 3 ft (0.9 m) of clearance behind the unit to
make water/brine connections to the evaporator, accessing the
TXV (thermostatic expansion valve), fluid thermistors, and
proof of flow switch.

On all units, leave 2 ft (610 mm) on one side for making re­frigeration connections (30MPA) or fluid connections
(30MPW) to condenser. See Fig. 4 and 5.

The floor must be strong enough to support the unit operat­ing weight (see Tables 1A and 1B and Fig. 4-6). If necessary,
add a supporting structure (steel beams or reinforced concrete
slabs) to the floor to transfer weight to nearest beams.

Do not store units in an area exposed to weath-

Additional weight of factory-installed sound enclosure op-

tion is 75 lb (34 kg).

CAUTION

Be sure interconnecting piping and electrical conduits

Step 1 — Inspect Shipment — Inspect unit for dam-

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

are suspended freely, and are not in contact with any
adjacent walls. Be sure unit capillaries are not rubbing
against anything. Damage to unit or walls may result.

Unit is top heavy. Unit may tip if handled without care.
Damage to unit or injury may result.

CAUTION

Step 2 — Position the Unit — The unit may be

moved by means of rollers under the rails or a forklift truck.
If accessory mobility kit 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. The factory-installed mobility kit option consists of
4 swivel-type wheels that are field-mounted to the legs of the
unit. See Fig. 7.

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