HANDLING
These units are shipped as completely assembled units
containing full operating charge, and care should be
taken to avoid damage due to rough handling.
The units are shipped without export crating unless it is
specified by Sales Order.
A unit should be lifted by inserting hooks through the
holes provided in the base rails. Spreader bars should
be used to avoid crushing the unit with the lifting chains.
(See Fig. 2.)
FIG. 2 – RIGGING THE CHILLER
INSPECTION
Immediately upon receiving the unit, it should be in-
spected for possible damage which may have occurred
during transit. If damage is evident, it should be noted
on the carrier’s freight bill. A written request for inspec-
tion by the carrier’s agent should be made at once. See
“Instruction” 50.15-NM for more information and details.
LOCATION
These units are designed for outdoor installations on
ground level, rooftop, or beside a building. The location
should be selected for minimum sun exposure and to
insure an adequate supply of fresh air for the condenser.
INSTALLATION
(See CLEARANCES, pages 4 & 5.) Avoid locations be-
neath windows or between structures where normal
operating sounds may be objectionable. The condenser
fans are propeller type and are not suitable nor intended
for use with duct work in the condenser air stream.
FOUNDATION
The unit should be mounted on a flat and level founda-
tion, floor or rooftop, capable of supporting the entire
operating weight of the equipment. If the unit is elevated
beyond the normal reach of service personnel, a suit-
able catwalk must be constructed around the unit. The
catwalk must be capable of supporting service person-
nel, their equipment, and the reciprocating compres-
sor(s).
Ground Level Locations
It is important that the units be installed on a substantial
base that will not settle. A one piece concrete slab with
footers extended below the frost line is highly recom-
mended. Additionally, the slab should not be tied to the
main building foundations as noise and vibration may
be transmitted.
Mounting holes (11/16" Dia.) are provided in the steel
channel for bolting the unit to its foundation. (See DI-
MENSIONS.)
For ground level installations, precautions should be
taken to protect the unit from tampering by or injury to
unauthorized persons. Screws on access panels will
prevent casual tampering. However, further safety pre-
cautions such as a fenced-in enclosure or locking de-
vices on the panels may be advisable. Check local au-
thorities for safety regulations.
Rooftop Locations
Choose a spot with adequate structural strength to safely
support the entire weight of the unit and service per-
sonnel. If the unit is elevated on a steel structure, use at
least a six-point mount. Care must be taken not to dam-
age the roof. Consult the building contractor or architect
if the roof is bonded. Roof installations should have
wooden beams (treated to reduce deterioration), cork,
or rubber under the base to minimize vibration.
SPRING ISOLATORS (OPTIONAL)
When ordered, eight (8)* vibration isolators will be fur-
nished with each unit. They are of the level adjusting
spring type, manufactured by either Mason Industries
or Vibration Mounting & Controls, Inc.
