Introduction
General
This manual describes the installation of a YORK YK Mod G Centrifugal Chiller. This unit can be
shipped as a single factory assembled, piped, wired package, requiring minimum field labor 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 field assembled under the supervision of a Johnson Controls
representative, otherwise installation will be as described in this instruction.
Field assembled units only
Use
Installation and Reassembly - Unit (Form 160.75-N3)
in conjunction with this installation guide.
This instruction is provided with all units that are field assembled.
The services of a Johnson Controls representative are provided to check the installation, supervise
the initial start-up and operation of all chillers installed in the Continental United States.
CAUTION
The Johnson Controls 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
Johnson Controls representative.
3. When units are shipped dismantled, notify the nearest Johnson Controls office in ample time
for a Johnson Controls 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.
