viced by an authorized YORK service
mechanic or a qualified service person
experienced in chiller installation. In-
stallation must comply with all appli-
cable codes, particularly in regard to
electrical wiring and other safety ele-
ments 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
panels. Before servicing, open and tag
all disconnect switches.

INSTALLATION
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 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 illustration below.
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 in
the carrier's freight bill. A written request for inspection
by the carrier's agent should be made at once. See "In-
struction" 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.
Clearances are listed under "Notes" in the "DIMEN-
SIONS" section.
