INSTALLATION
Storage Recommendations —
The 30RAP air-
cooled chillers are designed for outdoor installations. At
times, a delay in construction or other factors require that a
unit be stored for a period of time prior to installation. The
following guidelines should be used for unit storage.
PROVIDE MACHINE PROTECTION — Place and store
the unit in an area that will protect it from vandalism, acciden-
tal contact with vehicles, falling debris or construction waste.
Ideally, do not remove the shipping protection such as the coil
protectors. This will provide additional protection for the unit.
The unit can be stored outdoors.
INSPECTION DURING STORAGE — To ensure faster
installation when the time comes, the following inspection
schedule is recommended:
Every 3 Months
— The 30RAP units are shipped with a com-
plete operating charge of R-410A. Check each refrigerant cir-
cuit to be sure that there is positive pressure, at least 26 psig
(180 kPa) in the circuit. If a circuit is found to be without pres-
sure, contact a qualified refrigeration mechanic. The system
should be pressurized to find the leak. It should be repaired, de-
hydrated, and recharged with refrigerant. If a positive circuit
pressure was not found, the compressor oil should be changed
or at least sampled to determine if moisture is present. If mois-
ture is found in the compressor oil, the oil should be changed.
Every 6 Months
— Check the unit for damage, both physical
and from wildlife. Check the unit for nests from rodents, birds,
or insects. Depending on location, these organisms can cause
deterioration of components which may result in failure. Con-
sider an exterminator if necessary. If damage is found and it
will interfere with the installation, consider repairing the dam-
age before installation. Check the unit control box for signs of
moisture. If moisture is found, determine the entry path and
seal the leak.
Step 1 — Place and Rig the Unit
PLACING UNIT — Units are suitable for outdoor use only.
For 30RAP011-060 units, see Fig. 2. When parallel chillers
are aligned such that coils face each other, a minimum of
6 ft (1829 mm) separation is recommended. When the paral-
lel arrangement has only one coil drawing air from the space
between chillers, a minimum of 3.5 ft (1067 mm) is recom-
mended. When parallel chillers have no coils facing each
other (a back-to-back arrangement), be sure to maintain the
larger of the recommended service clearances associated
with each chiller (see the certified drawings). Due to NEC
(National Electric Code) regulations, a minimum clearance
of 4 ft (1219 mm) must be maintained on the side of the
chiller that has an electrical box. Chiller fan discharge must
be at least as high as adjacent solid walls. Installation in pits
is not recommended.
For 30RAP070-150 units, see Fig. 3. When chillers are ar-
ranged in parallel, a minimum of 10 ft (3048 mm) between
chillers is recommended. Acceptable clearance on the cooler
connection side or end opposite the control box of the unit can
be reduced to 3 ft (1 m) without sacrificing performance as
long as the remaining three sides are unrestricted. Acceptable
clearance on the side with a control box can be reduced to 4 ft
(1.3 m) due to NEC (National Electric Code) regulations, with-
out sacrificing performance as long as the remaining three
sides are unrestricted. Clearances between chillers in dual
chiller applications may be reduced to 6 ft (1.8 m) without sac-
rificing performance provided the remaining sides are unre-
stricted. For acceptable clearance with layout involving more
than 2 chillers, please contact application engineering.
These instructions cover installation of 30RAP011-150 air-
cooled liquid chillers. Refer to Fig. 4 and 5 for model number
to determine factory-installed options.
RIGGING — Preferred method for rigging is with spreader
bars from above the unit. Use shackles in lifting holes. Rig at a
single point with 4 cables for size 011-115 units, 6 cables for size
130 and 150 units, or use spread 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 gravi-
ty, and lifting ring dimensions. See Tables 1-3 and Fig. 6 for
unit weights. See Tables 6 and 7 for physical data. See Fig. 7
and 8 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 to
the unit. When in final position, raise from above to lift unit
off pad.
CAUTION
DO NOT re-use compressor oil or any oil that has been
exposed to the atmosphere. Dispose of oil per local codes
and regulations. DO NOT leave refrigerant system open to
air any longer than the actual time required to service the
equipment. Seal circuits being serviced and charge with
dry nitrogen to prevent oil contamination when timely
repairs cannot be completed. Failure to follow these proce-
dures may result in damage to equipment.
CAUTION
All panels must be in place when rigging. If they are not,
damage to unit could result.

† Clearance of 3.5 ft is required when a coil faces the wall. When
there is no coil facing the wall, see the certified drawing for the
