RIGGING THE UNIT
GENERAL
CAUTION:
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 7, must be checked before
placing units into operation.
1. Inspect unit for shipping damage.
2. Rig unit per Fig. 3.
3. Open 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 or sections 215 and 195 of YORK Service
Manuals for detailed piping.)
5. Make sure refrigerant piping and system are free of
moisture and scale. (YCR Models.)
6. Check for leaks; evacuate unit. (YCR Models.)
7. Check to see that unit is installed and operated within
LIMITATIONS shown on page 6.
The following paragraphs outline procedures to be fol-
lowed.
INSPECTION
As soon as it is received, the unit should be inspected
for any damage done in transit. If damage is evident, it
should be noted on the carriers freight bill. A separate
request for inspection by the carriers agent should be
made in writing at once. (See YORK Service Policy and
Procedures Shipping Damage Claims, Form 50.15-NM.)
LOCATION
The packaged liquid chillers may be located on the ground
floor on a flat and level concrete foundation, provided by
the purchaser, capable of supporting 150% of the oper-
ating weight. If the unit is mounted on an upper floor,
care must be exercised to isolate the unit and piping
from the walls and ceiling.
Standard packaged water chillers are constructed for
general purpose, indoor application (40°F to 115°F, am-
bient) and are not intended for wet, corrosive, or explo-
sive atmospheres. Installation should allow for water
drain, ventilation, and clearance for service, including tube
pulling. Any questionable application situations should
be referred to the factory for guidance.
HANDLING
Each chiller is skidded at the factory. Care should be
used during handling to avoid damage to the control panel,
solenoid valves, transducers, refrigerant piping, etc.
Normally, the chiller can be moved into position using a
lift truck or pipe rollers. If the unit must be lifted by means
of a crane or hoist, use the four lugs provided. (See Fig.
3.) Spreader bars should be used to avoid damaging the
unit with the lifting chains.
