TRANSPORTATION, RIGGING AND STORAGE
3.1 General
YK units are shipped as a single factory assembled,
piped, wired package, requiring minimum installation
to make chilled water connections, condenser water
connections, refrigerant atmospheric relief connections,
and electrical power connections.
Refrigerant and oil charges are shipped separately
(unless optional condenser 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 fi eld assembled under the supervision of a York
representative.
FIELD ASSEMBLED UNITS ONLY
Use Form 160.73-N3 in conjunction with this manual.
This instruction will be furnished with all units that are to
be fi eld assembled. Extra copies may be ordered from
the York Publication Distribution Centre.
A York authorised representative must check the
installation, supervise the initial start-up and operation
of all newly installed chillers.
The York Warranty may be voided if the
following restrictions are not adhered to:
CAUTION
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 offi ce 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 fi nal power supply connections to the
compressor motor or control centre.
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 (40°C maximum.) or steam
through the evaporator or condenser at any time.
3.2 Shipment
The chiller may be ordered and shipped in any of the
following forms:
