FORM 150.63-NM6 (1020)
To ensure warranty coverage, this
equipment must be commissioned
and serviced by an authorized YORK
service 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 cutout settings, design working
pressures, and ventilation require-
ments 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 CHECK LIST
The following items, 1 through 5, must be checked
before placing the units in operation.
1. Inspect the unit for shipping damage.
2. Rig unit using spreader bars.
3. Open the unit only after piping is installed and
evacuation in 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).
SECTION 1 - INSTALLATION
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 nitrogen holding charge, but
require field installation of a liquid line filter drier, TXV,
liquid line solenoid, sight glass, refrigerant, discharge/
return air temperature sensor (if used), and refrigerant
piping 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 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 inspec-
tion by the carrier’s agent should be made at once. See
“Instruction” manual, Form 50.15-NM for more infor-
mation and details.
LOCATION AND CLEARANCES
The YCUL Condensing Units are designed for outdoor
installation. When selecting a site for installation, be
guided by the following conditions:
1. For outdoor locations of the unit, select a place
having an adequate supply of fresh air for the con-
denser.
2. Avoid locations beneath windows or between
structures where normal operating sounds may be
objectionable.
3. Installation sites may be either on the roof, or at
ground level. (See FOUNDATION)
4. The condenser fans are the propeller-type, and are
not recommended for use with duct work in the
condenser air stream.
5. When it is desirable to surround the unit(s), it is
recommended that the screening be able to pass
the required chiller CFM without exceeding 0.1"
of water external static pressure.
