INSTALLATION
WARRANTY
To protect warranty, this equipment must be in-
stalled and serviced by an authorized YORK ser-
vice mechanic or a qualified service person expe-
rienced in chiller installation. Installation must com-
ply with all applicable codes, particularly in regard
to electrical wiring and other safety elements such
as relief valves, HP cutout settings, design work-
ing pressures and ventilation requirements con-
sistent with the amount and type of refrigerant
charge.
Lethal voltages exists within the control panel. Be-
fore servicing, open and tag all disconnect
switches.
INSTALLATION CHECK LIST
The following items, 1 thru 5, must be checked before
placing units into operation.
1. Inspect the two modules for shipping damage.
2. Rig each unit per Fig. 4. Remove shipping braces,
page 13 after installation.
3. Open unit only to install water piping system. Do not
remove protective covers from water connections
until piping is ready for attachment. Check water pip-
ing to insure cleanliness.
4. Pipe unit using good piping practice and consistent
with local code requirements.
5. Check to see that unit is installed and operated within
OPERATIONAL LIMITATIONS shown on page 7.
The following pages outline procedures to be followed.
HANDLING
These units are shipped as two separate modules for ease
of handling, each containing full operating charge. Care
should be taken to avoid damage due to rough handling.
Each module is shipped without export crating unless it
is specified by Sales Order.
A unit should be lifted by inserting hooks through the
holes provided in unit base rails. Spreader bars should
be used to avoid crushing the unit with the lifting chains.
(See Fig. 4).
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 inspection
by the carrier’s agent should be made at once. See In-
struction 50.15-NM for more information and details.
LOCATION AND CLEARANCES
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.
The units must be installed with sufficient clearances
for air entrance to the condenser coil, for air discharge
away from the condenser, and for servicing access.
In installations where winter operation is intended and
snow accumulations are expected, additional height
must be provided to insure normal condenser air flow.
(See DIMENSIONS.)
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. See PHYSICAL
DATA for operating weight. If the unit is elevated be-
yond the normal reach of service personnel, a suitable
catwalk must be constructed around the unit. The cat-
walk must be capable of supporting service personnel,
their equipment, and the reciprocating compressors.
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 are provided in the steel channel for
bolting the unit to its foundation. (See DIMENSIONS)
