GENERAL
To ensure warranty coverage, this
equipment must be commissioned and
serviced by an authorized YORK ser-
vice mechanic or a qualified service
person experienced in chiller instal-
lation. 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 require-
ments consistent with the amount and
type of refrigerant charge.
Lethal voltages exist within the con-
trol panels. Before servicing, open and
tag all disconnect switches.
INSTALLATION CHECK LIST
The following items, 1 through 5, must be checked be-
fore placing the units in operation.
1. Inspect the unit for shipping damage.
2. Rig unit using spreader bars (see photo below).
1
3. Open the unit only after piping is installed and
evacuation is complete.
4. Pipe unit using good piping practice (refer to
ASHRAE handbook).
5. Check to see that the unit is installed and operated
within limitations (Refer to LIMITATIONS).
The following pages outline detailed procedures to be
followed to install and start-up the unit.
HANDLING
These condensing units are shipped as completely as-
sembled units containing a 6 lb. (2.7 kg) refrigerant
holding charge, but require field installation of a liquid
line filter drier, TXV, liquid line solenoid, sight glass,
discharge air temperature sensor, and refrigerant pip-
ing to the air handling unit. 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 must
be used to avoid crushing the unit frame rails with the
lifting chains (See photo).
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 in-
spection by the carrier’s agent should be made at once.
See “Instruction” manual, Form 50.15-NM for more
information and details.
LOCATION AND CLEARANCES
These units are designed for rooftop or ground level
outdoor installations. Location should be selected for
minimum sun exposure and to insure adequate supply
of fresh air for the condenser coils. The units must be
installed with sufficient clearances for air entrance to
the condenser coil, for air discharge away from the con-
denser, 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 “Note” in the “DIMEN-
SIONS” section.
