FIG. 3 – RIGGING THE CHILLER
WARNING:
To protect warranty, this equipment must be in-
stalled and serviced by an authorized YORK ser-
vice mechanic or a qualified service person experi-
enced 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 consis-
tent with the amount and type of refrigerant charge.
Lethal voltages exist 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 plac-
ing units into operation. Inspect unit for shipping damage.
1. Inspect unit for shipping damage.
2. Rig unit per Fig. 3. Remove unpainted shipping
braces.
3. Open unit only to install water piping system. Do not
remove protective covers from water connections un-
til piping is ready for attachment. Check water piping
to insure cleanliness.
4. Pipe unit using good piping practice (see ASHRAE
handbook or section 215 and 195 or YORK Service
Manuals for detailed piping.)
5. Check to see that unit is installed and operated within
LIMITATIONS shown on page 7.
The following pages outline procedures to be followed.
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 unit base rails. Spreader bars should
be used to avoid crushing the unit with the lifting chains.
(See Fig. 3).
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, page 8).
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 beyond the
normal reach of service personnel, a suitable catwalk
must be constructed around the unit. The catwalk must
be capable of supporting service personnel, their equip-
ment, and the reciprocating compressors.
