JOHNSON CONTROLS 8
FORM 201.23-EG1 (1013)
Accessories and Options
• Louvered Panels (condenser coils only)
– Lou-
vered panels, painted the same color as the unit, are
mounted over the exterior con denser coil faces on the
sides of the unit to visually screen and protect coils.
(
Factory-mounted
)
• Louvered Panels (full unit)
– Louvered panels,
painted the same color as the unit, enclose the unit
to protect condenser coils from incidental damage,
visually screen internal components, and prevent
unauthorized access to internal components. (
Fac-
tory-mounted
)
• Louvered (Condensers)/Wire Panels (Mechanical)
– Louvered panels, painted the same color as the unit,
are mounted on external condenser coil faces. Heavy
gauge, welded wire-mesh, coated to resist corrosion,
around base of machine to restrict unauthorized ac -
cess. (
Factory-mounted
)
EVAPORATOR OPTIONS:
•
1-1/2” Insulation
– Double thickness insulation pro -
vided. (
Factory-mounted
)
•
Raised Face Flange Accessory
for cooler nozzles:
♦ 150 psig (10.3 barg), welded flanges (field kit,
matching pipe flange by contractor).
♦ 150 psig (10.3 barg) companion weld flanges. (field
kit - Not available with 460V units).
♦ 150 psig (10.3 barg), ANSI/AWWA C-606 COU-
PLINGS (field kit, matching pipe flange by contrac -
tor).
• Opposite Handed Evaporator Water Connections
for ease of installation. Standard water connections
are on the left-hand side of the unit, when viewed from
the control panel end.
GENERAL OPTIONS:
FLOW SWITCH ACCESSORY -
Vapor proof SPDT, NEMA
3R switch, 150 psig (10.3 barg) DWP, 20°F to 250°F (-7°C
to 121°C) with 1” NPT (IPS) connection for upright mount -
ing in horizontal pipe (This flow switch or equivalent must
be furnished with each unit). (
Field-mounted
).
DIFFERENTIAL PRESSURE SWITCH -
Alternative to the
paddle-type flow switch. 3-45 psig (0.2-3 barg) range with
1/4" NPTE pressure connections. (
Field-mounted
)
BUILDING AUTOMATION SYSTEM INTERFACE -
Chiller
to accept 4 to 20mA or 0 to 10 VDC input to reset the leav -
ing chilled liquid temperature. (
Factory-mounted
)
MULTI-UNIT SEQUENCE CONTROL -
Separate se-
quencing control center provided to permitting control
of up to eight chillers in parallel based on mixed liquid
temperature (interconnecting wiring by others). (
Field-
mounted
)
SERVICE ISOLATION VALVE
– Service suction isolation
valve added to unit for each refrigerant circuit. (
Factory-
mounted
)
CHICAGO CODE RELIEF VALVE -
Special relief valves
per Chicago code. (
Factory-mounted
)
PRESSURE RELIEF (CE/PED) SERVICE VALVE KIT
-
Each relief valve is mounted on a sealable ball valve to
aid maintenance. (
Factory-mounted
)
CIRCUIT BREAKER
– Power panel will come equipped
with a factory mounted circuit breaker at the point of
incoming single or multi-point connections that provides
the following:
• A means to disconnect power mounted on chiller.
• Circuit breaker(s) sized to provide the motor branch
circuit protection, short circuit protection and ground
fault protection for the motor branch-circuit conductors,
the motor control apparatus and the motors. (Chiller
mounted circuit breaker option sized for branch circuit
protection eliminates the need to provide a separate
‘line of sight’ disconnect and separate branch circuit
protection device.)
• A lockable operating handle that extends through
power panel door. This allows power to be discon -
nected without opening any panel doors.
• A Short Circuit Withstand Rating of 65,000 amps
when the chiller electrical enclosure when using cir -
cuit breaker option is 380, 400, & 460. Rated IAW
UL508.
VIBRATION ISOLATION:
• Elastomeric Isolation
– This option is recommended
for normal in stallations. It provides very good perfor-
mance in most applications for the least cost. (
Field-
mounted
)
• 1” Spring Isolators
– Spring and cage type isolators
for mounting under the unit base rails. They are level
adjustable. 1” nominal deflection may vary slightly by
appli cation. (
Field-mounted
)
• 2” Seismic Spring Isolators
– Restrained Spring-
Flex Mounting isolators incorporate a rugged welded
steel housing with vertical and horizontal limit stops.
Housings de signed to withstand a minimum 1.0g ac -
celerated force in all directions up to 2” (51mm). The
deflection may vary slightly by application. They are
level adjustable. (
