INSTALLATION
WARNING
To protect warranty, this equipment must be installed
and serviced by an authorized YORK service
mechanic or a qualified service person experienced in
chiller installation. Installation must comply with all
applicable codes, particularly in regard to electrical
wiring and other safety elements such as relief valves,
HP cut-out settings, design working pressures, and
ventilation requirements consistent with the amount
and type of refrigerant charge.
Lethal voltages exist within the control panel. Before
servicing, open and tag all disconnect switches.
INSTALLATION CHECK LIST
The following items, 1 thru 5, must be checked before
placing the units in operation.
1. Inspect the unit for shipping damage.
2. Rig unit per Fig. 6A or 6B. Remove unpainted shipping
braces.
3. Open the unit only to install water piping system. Do
not remove protective covers from water connections
until piping is ready for attachment. Check water
piping to insure cleanliness.
4. Pipe unit using good piping practice (see ASHRAE
handbook section 215 and 195 or YORK Service
Manuals for detailed piping).
5. Check to see that the unit is installed and operated
within LIMITATIONS.
The following pages outline detailed procedures to be
followed to install and start up the chiller.
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 with 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 frame rails with the lifting
chains. (See Fig. 6A & 6B)
INSPECTION
Immediately upon receiving the unit, it should be
inspected for possible damage which may have occurred
during transit. If damage is evident, it should be noted in
the carrier’s freight bill. A written request for inspection by
the carrier’s agent should be made at once. See “Instruc-
tion” manual, Form 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. Location
should be selected for minimum sun exposure and to
insure 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.)
