Shipping
General
This instruction describes the installation of a model YD liquid chilling unit. The H9, K1 and K2
compressor models are the only chiller combination that can be shipped as a single factory
assembled unit. This would include complete unit assembly, system piping, and system wiring.
Minimal field service will be necessary to complete the chiller installation for the following
connections; evaporator chilled water connections, condenser water connections, refrigerant
atmospheric relief connections and electrical power connections. (Refrigerant and oil charges are
shipped separately).
All other model YD liquid chilling units will be shipped disassembled, Form 7. Chillers shipped
disassembled 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
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.
CAUTION
The Johnson Controls Warranty may be voided if the following restrictions are not adhered to.
1. Do not open any valves or connections 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 motors or control center.
5. Do not charge the compressors with oil.
6. Do not charge the unit with refrigerant.
7. Do not attempt to start the system.

time.
