SAFETY CONSIDERATIONS
Installing, starting up, and servicing air-conditioning equip-
ment can be hazardous due to system pressures, electrical
components, and equipment location (roofs, elevated structures, etc.).
Only trained, qualified installers and service mechanics
should install, start up, and service this equipment (Fig. 1).
Untrained personnel can perform basic maintenance func-
tions such as cleaning coils. All other operations should be
performed by trained service personnel.
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.
•Keep quenching cloth and fire extinguisher nearby when
brazing.
•Use care in handling, rigging, and setting bulky
equipment.
These instructions cover installation of 30RAP010-060 air-cooled
liquid chillers. Refer to Fig. 2 for model number to determine factoryinstalled options.
.
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.
INSTALLATION
Step 1 — Rig and Place the Unit
RIGGING — Preferred method for rigging is with spreader
bars from above the unit. Use hooks in lifting holes. Rig at a
single point with 4 cables or use spreader bars. All panels must
be in place when rigging. See rigging label on unit for details
concerning shipping weights, distance between lifting holes,
center of gravity, and lifting ring dimensions. See Tables 1A
and 1B for physical data. Refer to Fig. 3 for unit weights.
See Fig. 4 for rigging label.
If overhead rigging is not possible, place chiller on skid or
pad for rolling or dragging. When rolling, use a minimum of
3 rollers. When dragging, pull the pad. Do not apply force tothe unit. When in final position, raise from above to lift unit
off pad.
CAUTION
All panels must be in place when rigging. Damage to unit
could result.
PLACING UNIT — There must be at least 3 ft (0.9 m) for
service and for unrestricted airflow on all non-coil sides of unit,
and a minimum of 3.5 ft (1.1 m) clear air space on coil sides.
For multiple units, allow 8 ft (2.48 m) separation between units
for airflow and service.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

MOUNTING UNIT — When unit is in proper location, use
Fig. 4 — Unit Rigging Label Detail
a30-4916
of mounting holes in base rails is recommended for securing
unit to supporting structure, or for mounting unit on vibration
isolators if required. See Fig. 4. Fasteners for mounting unit are
field supplied. Be sure unit is level to within
1
/8 in. per foot for
proper oil return to compressor.
Step 2 — Check Compressor Mounting — As
shipped, units with single compressors are held down with 4
bolts through rubber grommets. All units with tandem compresors are held down with 6 bolts per pair through grommets.
After unit is installed, verify mounting bolt torque 7 to10 ft-lb.
Step 3 — Cooler Fluid and Drain Piping Connections
ALL UNITS — These chillers are supplied with factoryinstalled strainer (including blow-down valve) in the entering
fluid piping and flow switch in the leaving fluid piping. Flow
switch wiring is factory installed. .
CAUTION
Do not circulate water through unit without strainer in
place. Failure to use the strainer represents abuse and may
impair or otherwise negatively affect the Carrier product
warranty.
Piping connections are located on the front of the chiller
when facing the control panel for sizes 010 to 030 and at the
end opposite the control panel for sizes 035 to 060. See
Fig. 5-10, depending on model.
All sizes have victaulic connections as shown in the physical data tables. Provide a means of venting air from the high
point of the field-installed piping as required. Install field-supplied drains in both the entering and leaving fluid connections.
After field piping is complete, freeze-up protection is recommended using inhibited ethylene glycol or other suitable inhibited antifreeze solution and electric heat tapes in areas
where piping is exposed to low ambient temperatures (34 F
[1 °C] or below). Heat tapes should possess a rating for area
ambients and be covered with a suitable thickness of closedcell insulation. Route power for heating tapes from a separately
fused disconnect. Identify disconnect as heat tape power source
with a warning that power must not be turned off except when
unit is being serviced.
The water connections are copper victaulic. Any connecting
pipe to the 30RAP pump package must be of a material that
will not cause any galvanic corrosion. For this reason, galvanized steel pipe or other dissimilar metals must not be used unless joined by a dielectric coupling.
Installation of water systems should follow sound engineering practice as well as applicable local and industry standards.
Improperly designed or installed systems may cause unsatisfactory operation and/or system failure. Consult a water treatment specialist or appropriate literature for information regarding filtration, water treatment, and control devices.
