SAFETY CONSIDERATIONS
Installing, starting up, and servicing this equipment can
be hazardous due to system pressures, electrical components,
and equipment location. Only trained, qualified installers and
service mechanics 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.
INTRODUCTION
These instructions cover installation of 30GXN,R080-528
liquid chillers with electronic controls and units with
factory-installed options (FIOPs).
INSTALLATION
Step 1 — Inspect Shipment —
Inspect unit for dam-
age upon arrival. If damage is found, immediately file a claim
with the shipping company. When considering location for the
unit, be sure to consult NEC (National Electrical Code, U.S.A.)
and/or local code requirements. Allow sufficient space for air-
flow, wiring, piping, and service as follows.
Front and Rear . . . 6 ft (1829 mm); from outer most edge*
Top . . . . . . . . . . . . . . . . . . . . . . . Do not restrict in any way
Ends . . . . . . . . . . . . 5 ft (1524 mm); from outer most edge*
*Outer most edge may include sound enclosure or hail
guard.
See Fig. 1-25 for unit dimensions and Table 1 for duplex
unit combinations. Ensure surface beneath unit is level and
capable of supporting the operating weight of the unit. See
Fig. 26-28 and Tables 2A-2D for unit mounting and operating
weights. Unit operating ranges are listed in Tables 3A and 3B.
Step 2 — Rig and Place Unit —
These units are de-
signed for overhead rigging and it is important that this method
be used. See Fig. 28 or rigging label on unit. Holes are provid-
ed in frame baserails; field-supplied 2-in. Schedule 40 pipes
pass through these holes, extending beyond frame far enough
to attach cables or chains on both sides.
As shown in Fig. 28, use the recommended length of chain
or cable to facilitate lifting of the unit. Two options have been
provided for the rigging of these units.
Rigging option 1 uses a central rigging point. The lifting
point must be a minimum of 13 ft (3.9 m) above the top of the
unit. For a more level lift, the chains or cables of the cooler/
compressor side must be shortened by about 20 in. (508 mm).
Use spreader bars to keep cables or chains clear of unit sides.
As further protection for the coil faces, leave plywood sheets
supplied for shipping in place against sides of unit, behind
cables or chains. Option 1 must be used for 30GXN,R204-350,
and applicable modular units.
ELECTRIC SHOCK HAZARD
To avoid the possibility of electrical shock,
open and tag all disconnects before install-
ing this equipment.
IMPORTANT: This equipment generates, uses, and can
radiate radio frequency energy. If not installed and used
in accordance with these instructions, this equipment
may cause radio interference. The equipment has been test-
ed and found to comply with the limits of a Class A
computing device as defined by the FCC (Federal Commu-
nications Commission, U.S.A.) Regulations, Subpart J of
Part 15, which are designed to provide reasonable protec-
tion against such interference when operated in a commer-
cial environment.
IMPORTANT: Rigging option 1 must be used for
30GXN,R204-350 and associated modular units. Sizes
080-178 and associated modular units may use either rig-
ging option 1 or 2.
