INSTALLATION
Storage —
If the unit is to be stored for a period of time
before installation or start-up, be sure to protect the machine
from construction dirt. Keep protective shipping covers in
place until the machine is ready for installation.
Step 1 — Place and Rig the Unit
PLACING UNIT — Units are suitable for outdoor use only.
For 30RAP010-060, see Fig. 2. When parallel chillers are
aligned such that coils face each other, a minimum of 6 ft (1829
mm) is recommended. When the parallel arrangement has
only one coil drawing air from the space between chillers, a
minimum of 3.5 ft (1067 mm) is recommended. When parallel
chillers have no coils facing each other (a back-to-back ar-
rangement), 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, U.S.A.) regu-
lations, a minimum clearance of 4 ft (1219 mm) must be main-
tained on the side of the chiller that has an electrical box. Chill-
er fan discharge must be at least as high as adjacent solid walls.
Installation in pits is not recommended.
For 30RAP070-150, see Fig. 3. When chillers are arranged
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 re-
maining 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, without sacrificing
performance as long as the remaining three sides are unrestrict-
ed. Clearances between chillers in dual chiller applications may
be reduced to 6 ft (1.8 m) without sacrificing performance pro-
vided the remaining sides are unrestricted. For acceptable
clearance with layout involving more than 2 chillers, please
contact application engineering.
These instructions cover installation of 30RAP010-150 air-
cooled liquid chillers. Refer to Fig. 4 for model number to de-
termine 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 010-115 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 con-
cerning shipping weights, distance between lifting holes, center
of gravity, and lifting ring dimensions. See Tables 1A and 1B
for physical data. Refer to Fig. 5-8 for unit weights. See
Fig. 9A and 9B 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.

* Minimum for when coils face each other. Less clearance is
required in other configurations.
† 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
required service clearance.
