Accessories and Options
All accessories and options are factory installed unless otherwise noted.
POWER OPTIONS
Single Point Supply Terminal Block
- The standard power wiring connection on all mod-
els is a single point power connection to a factory provided terminal block. Components
included are the enclosure, terminal-block and interconnecting wiring to the compressors.
Separate external protection must be supplied, by others, in the incoming power wiring.
(Do not include this option if either the Single-Point Non-Fused Disconnect Switch or
Single-Point Circuit Breaker options have been included.)
Single Point Non-Fused Disconnect Switch
- An optional unit-mounted disconnect switch
with external, lockable handle (in compliance with Article 440-14 of N.E.C.), can be supplied
to isolate the unit power voltage for servicing. Separate external fusing must be supplied,
by others in the power wiring, which must comply with the National Electrical Code and/or
local codes.
Single Point Circuit Breaker
- An optional unit mounted circuit breaker with external, lock-
able handle (in compliance with N.E.C. Article 440-14), can be supplied to isolate the power
voltage for servicing.
Multiple Point Circuit Breaker
– Optional multiple point supply with independent system
circuit breakers and locking external handles (in compliance with Article 440-14 of N.E.C)
can be factory supplied. Selecting this option also selects optional compressor external
overloads, for reduced MCA.
Control Transformer
– Converts unit power voltage to 115-1-60 (0.5 or 1.0 KVA capacity).
Factory mounting includes primary and secondary wiring between the transformer and the
control panel.
Compressor External Overloads
– Optional compressor motor overloads can be factory
mounted in the unit control/power panel. This option will reduce the chiller MCA (minimum
circuit ampacity) and allow for reduced wire sizing to the unit. This option is not available
for applications with Leaving Condenser Water Temperature (
LCWT
) greater than 110ºF
(43ºC).
CONTROLS OPTIONS
Language LCD And Keypad
- Standard display language and keypad is in English. Span-
ish, French, German, and Italian are available as an option.
HEAT EXCHANGER OPTIONS
Flow Switch
– An optional flow switch can be factory supplied for the evaporator. Vapor-
proof SPDT, NEMA 3R switch, 150 PSIG (10.3 bar) DWP, 20°F to 250°F (-29°C to 121°C)
with 1” NPT (IPS) connection for upright mounting in horizontal pipe. The flow switch or its
equivalent must be furnished with each unit. (
