FORM 160.73-N1 (904)
INTRODUCTION
GENERAL
This instruction describes the installation of a MODEL
YK MaxE™ Liquid Chilling Unit. This unit is shipped
as a single factory assembled, piped, wired package,
requiring a minimum of field labor to make chilled water
connections, condenser water connections, refrigerant
atmospheric relief connections, and electrical power
connections. (Refrigerant and oil charges shipped
separately unless optional condensor isolation valves
are ordered.)
Chillers can also be shipped dismantled when required by
rigging conditions, but generally it is more economical
to enlarge access openings to accommodate the factory
assembled unit. Chillers shipped dismantled MUST
be field assembled under the supervision of a YORK
representative, but otherwise installation will be as
described in this instruction.
FIELD ASSEMBLED UNITS ONLY
Use Form 160.73-N3 in conjunction with this installation
instruction. This instruction will be furnished with all
units that are to be field assembled. Extra copies may
be ordered from the York Publication Distribution
Center.
The services of a YORK representative will be furnished
to check the installation, supervise the initial start-up
and operation of all chillers installed within Continental
United States.
The YORK Warranty may be voided
if the following restrictions are not
adhered to:
1. No valves or connections should be opened under
any circumstances because such action will result
in loss of the factory nitrogen charge.
2. Do not dismantle or open the chiller for any
reason except under the supervision of a YORK
representative.
3. When units are shipped dismantled, notify the
nearest YORK office in ample time for a YORK
representative to supervise rigging the unit
to its operating position and the assembly of
components.
4. Do not make final power supply connections to the
compressor motor or control center.
5. Do not charge the compressor with oil.
6. Do not charge the unit with refrigerant.
7. Do not attempt to start the system.
8. Do not run hot water (110°F / 43°C max) or steam
through the evaporator or condenser at any time.
SHIPMENT
The chiller may be ordered and shipped in any of the
following forms:

YORK INTERNATIONAL
All wiring integral with compressor is left on
it, and all conduit is left on shell. All openings
on compressor, oil separator, and shell are
closed and charged with dry nitrogen (2 to 3
PSIG) (115/122 kPa).
Miscellaneous packaging of control center,
tubing, water temperature controls, wiring,
oil, isolators, solid state starter (option), etc.;
refrigerant charge shipped separately.
Units shipped dismantled MUST be re-
assembled by, or under the supervision
of, a YORK representative. (See Form
160.73-N3)
Form 7 – Split Shells – Shipped as three major
assemblies. Unit first factory assembled,
refrigerant piped, wired and leak tested; then
dismantled for shipment. Compressor/motor
assembly removed from shells and skidded.
Evaporator and condenser shells are separated
at tube sheets and are not skidded. Refrigerant
lines between shells are flanged and capped,
requiring no welding.
All wiring integral with compressor is left on
it. All wiring harnesses on shells are removed.
All openings on compressor and shells are
closed and charged with dry nitrogen (2 to 3
PSIG) (115/122 kPa).
Miscellaneous packaging of control center,
tubing, water temperature controls, wiring,
oil isolators, solid state starter (option), etc.;
refrigerant charge shipped separately.
Units shipped dismantled MUST be re-
assembled by, or under the supervision
of, a YORK representative. (See Form
160.73-N3)
When more than one chiller is involved, the major
parts of each unit will be marked to prevent mixing of
assemblies. (Piping and Wiring Drawings to be furnished
by YORK.)
INSPECTION – DAMAGE – SHORTAGE
The unit shipment should be checked on arrival to see
that all major pieces, boxes and crates are received. Each
unit should be checked on the trailer or rail car when
received, before unloading, for any visible signs of
damage. Any damage or signs of possible damage must
be reported to the transportation company immediately
for their inspection.
YORK WILL NOT BE RESPONSIBLE FOR ANY
DAMAGE IN SHIPMENT OR AT JOB SITE OR
LOSS OF PARTS. (Refer to Shipping Damage Claims,
Form 50.15-NM)
When received at the job site all containers should be
opened and contents checked against the packing list.
Any material shortage should be reported to YORK
immediately. (Refer to Shipping Damage Claims, Form
50.15-NM)
CHILLER DATA PLATE
A unit data plate is mounted on the control center
assembly of each unit, giving unit model number; design
working pressure; water passes; refrigerant charge;
serial numbers; and motor power characteristics and
connection diagrams.
Additional information may be found on the motor
data plate. This information should be included when
contacting the factory on any problem relating to the
motor.
RIGGING (See Fig. 8)
The complete standard chiller is shipped without skids.
(When optional skids are used it may be necessary to
remove the skids so riggers skates can be used under the
unit end sheets to reduce overall height.)
Each unit has four (4) lifting holes (two in each end) in
the end sheets which should be used to lift the unit.
Care should be taken at all times during rigging and
handling of the chiller to avoid damage to the unit and
its external connections. Lift only using holes shown
in Fig. 8.
Do not lift the unit with slings around
motor/compressor assembly or by
means of eyebolts in the tapped holes
of the compressor motor assembly. Do
not turn a unit on its side for rigging.
Do not rig vertically.
