Accessories and Options
All accessories and options are factory mounted unless otherwise noted.
ELECTRICAL OPTIONS
Single-Point Supply Terminal Block – Standard. Includes enclosure, terminal-block
and interconnecting wiring to the compressors. Separate external protection must be sup-
plied, by others, in the incoming compressor-power wiring. (Do not include this option if
either the SinglePoint NonFused Disconnect Switch or Single-Point Circuit Breaker op-
tions have been included.)
Single-Point Non-Fused Disconnect Switch – Unit-mounted disconnect switch with ex-
ternal, 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 – A unit mounted circuit breaker with external, lockable
handle (in compliance with N.E.C. Article 440-14), can be supplied to isolate the power
voltage for servicing. (This option includes the Single-Point Power connection.)
Control Transformer – Converts unit power voltage to 115-1-60 or 115-1-50 if 50Hz is
selected (0.5 or 1.0 KVA capacity). Factory mounting includes primary and secondary wir-
ing between the transformer and the control panel.
Power Factor Correction Capacitors – Will correct unit compressor power factors to
0.90-0.95.
CONTROL OPTIONS
Ambient Kit (Low) – Standard units will operate to 25°F (-4°C). This accessory includes
all necessary components to permit chiller operation to 0°F (-18°C). (This option includes
the Discharge Pressure Transducer/Readout Capability option.) For proper head pres-
sure control in applications below 25°F (-4°C), where wind gusts may exceed five mph, it
is recommended that Optional Condenser Louvered Enclosure Panels also be included.
Ambient Kit (High) – Required if units are to operate when the ambient temperature is
above 110°F (43°C). Includes discharge pressure transducers. (This option includes the
Discharge Pressure Transducer / ReadoutCapability option.) (Field-Mounted.)
Language LCD And Keypad Display – Spanish, French, and German unit LCD controls
and keypad display available. Standard language is English.
Discharge Pressure Transducers And Readout Capability – The addition of pressure
transducers allows models to sense and display discharge pressure. This is recommend-
ed for glycol chilling applications. (This option is included with either the low or high ambi-
ent kits.)
Suction Pressure Transducers – Permits unit to sense and display suction pressure.
This capability is standard.
