GENERAL
This instruction describes the installation of a MOD-
EL YD Liquid Chilling Unit. The K1 & K2 compres-
sor 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 sys-
tem wiring. Minimal field service will be necessary to
complete the chiller installation for the following con-
nections; evaporator chilled water connections, con-
denser water connections, refrigerant atmospheric relief
connections and electrical power connections. (Refrig-
erant and oil charges are shipped separately).
All other MODEL YD Liquid Chilling Units will be
shipped dis-assembled, Form 7. Chillers shipped dis-
assembled MUST be field assembled under the supervi-
sion of a Johnson Controls representative, but otherwise
installation will be as described in this instruction.
FIELD ASSEMBLED UNITS ONLY
Use the
Field Reassembly Instructions (Form 160.69-
NM4)
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 rea-
son 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.
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.
Form 2 - Factory Assembled Unit, Complete
with Motors
(Refrigerant and oil charges shipped separately).
• K1 and K2 Liquid Chilling Units.
• The motor/compressor assemblies mounted, with
all necessary interconnecting piping assembled.
OptiView™ Control Center is mounted on the
unit. Complete unit factory leak tested, evacuated
and charged with holding charge of nitrogen.
• Miscellaneous material – K1, K2 - Four (4), K3,
K4, K7(8) vibration isolation pads (or optional
spring isolators and brackets).
Units shipped dismantled MUST be re-
assembled by, or under the supervision
of, a Johnson Controls representative.
See Field Reassembly Instructions (Form
160.69-NM3).
Form 3 - Drivelines Separate from Shells
• K1 and K2 Liquid Chilling Units.
Shipped as three major assemblies. Unit first factory
assembled, refrigerant piped, wired and leak tested;
then dismantled for shipment. Compressor/motor as-
semblies removed from shells and skidded. Evapora-
tor/condenser is not skidded.
All wiring integral with compressors are left on
them, and all conduit is left on shell. All openings on
compressors, oil separator, and shells are closed and
charged with dry nitrogen (2 to 3 PSIG) (14-21 kPa).
The control center, oil pump panel, and associated wir-
ing remain mounted on the evaporator shell. Miscel-
laneous packaging of tubing, wiring, oil, isolators, etc.
and the refrigerant charge shipped separately.
