INSTALLATION
Location —
Do not store units in an area exposed to weath-
er because of sensitive control mechanisms and electronic
devices. Locate unit indoors.
When considering location, consult National Electrical
Code (NEC) and local code requirements. Allow sufficient
space for wiring, piping, and service. Install the 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 the control
box access door. Additional clearance may be required per lo-
cal codes. Prior to installation determine which direction the
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 opposite the con-
trol box end to make water/brine connections to the evaporator,
accessing the TXV (thermostatic expansion valve) or EXV
(electronic expansion valve), fluid thermistors, and proof of
flow switch.
For units without water manifold option, leave 2 ft
(610 mm) on the left facing control box side for making
refrigeration connections (30MPA) or leave 2 ft (610 mm)
on one side for making fluid connections (30MPW) to
condenser. See Fig. 6-17.
The floor must be strong enough to support the unit operat-
ing weight (see Tables 1-4, Fig. 6-14, and Fig. 18). If necessary,
add a supporting structure (steel beams or reinforced concrete
slabs) to the floor to transfer weight to the nearest beams.
Additional weight of factory-installed sound enclosure op-
tion is 75 lb (34 kg). Additional operating weight of 30MPA
water manifold option is 218 lb (99 kg). Additional operating
weight of 30MPW water manifold option is 436 lb (198 kg).
Multiple chiller applications using the Vibration Isolator
Springs Accessory Kit should be set on a mounting frame,
which should then be installed on the isolator springs. I-beam
or square metal tubing are acceptable materials for the mount-
ing frame. Each chiller MUST be supported in the center (un-
der the heat exchangers) by the mounting frame, however iso-
lators are only necessary at the four corners of each unit. Use
Fig. 18, for the corner weights of each when supported in four
locations.
For standalone units (chillers which are not connected via
common water piping), 30MP 015-045 must be supported at
the four corner locations shown in Fig. 18. 30MP 050-071
must be supported at the six locations shown in Fig. 19.
WARNING
If a 30MPE electrical distribution panel is purchased, it is
crucial that each individual 30MP chiller be placed in the
appropriate position relative to its corresponding 30MPE
electrical distribution panel. Failure to do so could cause
personal injury or death. Please consult the 30MPE Electri-
cal Distribution Panel Installation Instructions for more
details.
CAUTION
Be sure interconnecting piping and electrical conduits
are suspended freely, and are not in contact with any
adjacent walls. Be sure unit capillaries are not rubbing
against anything. Damage to the unit or walls may result.
