FOUNDATION
The unit should be mounted on a fl at and level foun-
da tion, fl oor, or rooftop capable of supporting the entire
operating weight of the equipment. See PHYSICAL
DATA for op er at ing weight. If the unit is elevated be yond
the normal reach of service personnel, a suitable catwalk
must be capable of supporting service per son nel, their
equipment, and the compressors.
GROUND LEVEL LOCATIONS
It is important that the units be installed on a sub stan tial
base that will not set tle. A one piece concrete slab with
footers extended below the frost line is highly rec om -
mend ed. Additionally, the slab should not be tied to
the main building foundations as noise and vibration
may be transmitted. Mounting holes are provided in the
steel channel for bolting the unit to its foundation. (See
DI MEN SIONS.)
For ground level installations, precautions should be
tak en to protect the unit from tampering by or injury to
un au tho rized persons. Screws and/or latches on ac cess
pan els will prevent casual tampering. However, further
safe ty precautions such as a fenced-in enclosure or
locking devices on the panels may be advisable.
ROOFTOP LOCATIONS
Choose a spot with adequate structural strength to safe ly
support the entire weight of the unit and service per-
son nel. Care must be taken not to damage the roof.
Consult the building contractor or architect if the roof is
bonded. Roof installations should have wooden beams
(treated to reduce de te ri o ra tion), cork, rubber, or vi bra -
tion isolators under the base to minimize vibration.
NOISE SENSITIVE LOCATIONS
Efforts should be made to assure that the chiller is not
located next to occupied spaces or noise sensitive ar eas
where chiller noise level would be a problem. Chill er
noise is a result of compressor and fan op er a tion. Con-
sid er ations should be made utilizing noise levels pub-
lished in the YORK Engineering Guide for the specifi c
chiller model. Sound blankets for the compressors and
low sound fans are available.
SPRING ISOLATORS (OPTIONAL)
When ordered, four (4) isolators will be fur nished.
Identify the isolator, locate at the prop er mount ing point,
and adjust per instructions. See APPENDIX 1.
COMPRESSOR MOUNTING
The compressors are mounted on four (4) rubber iso-
la tors. The mounting bolts should not be loosened or
ad just ed at installation of the chiller.
REMOTE COOLER OPTION
For units using remote cooler option, refer to in struc tions
included with miscellaneous cooler parts kit.
The unit and remote cooler is shipped with a 6 lb. (2.7
kg) nitrogen hold ing charge. The nitrogen charge must
be re moved, and system evacuated, and the refrigerant
charge must be weighed-in ac cord ing to the op er at ing
charge listed un der PHYS I CAL DATA. Ad di tion al charge
must also be added for the re frig er ant lines.
CHILLED WATER PIPING
General – When the unit has been located in its
fi nal position, the unit water piping may be con nect ed.
Nor mal installation precautions should be observed in
or der to receive maximum operating effi ciencies. Piping
should be kept free of all for eign matter. All chilled wa ter
evap o ra tor piping must comply in all respects with local
plumb ing codes and ordinances.
Since elbows, tees and valves decrease pump ca pac i ty,
all piping should be kept as straight and as simple as
possible. All piping must be supported in de pen dent
of the chiller.
Consideration should be given to
com pres sor ac cess when laying out
water piping. Routing the water pip-
ing too close to the unit could make
com pres sor servicing/re place ment
dif fi cult.
