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 anges (eld kit,
matching pipe ange by contractor).
♦ 150 psig (10.3 barg) companion weld anges. (eld
kit - Not available with 460V units).
♦ 150 psig (10.3 barg), ANSI/AWWA C-606 COU-
PLINGS (eld kit, matching pipe ange 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 ow switch or equivalent must
be furnished with each unit). (Field-mounted).
DIFFERENTIAL PRESSURE SWITCH - Alternative to the
paddle-type ow 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 deection 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
deection may vary slightly by application. They are
level adjustable. (Field-mounted)
