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 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, but otherwise installation will
be as described in this instruction.
fiEld assEMBlEd units onlY
Use Form 160.75-N3 in conjunction with this installation
instruction. This instruction will be furnished with all
units that are to be field assembled.
The services of a Johnson Controls representative will be
furnished to check the installation, supervise the initial
start-up and operation of all chillers installed within
Continental United States.
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.
