17. Freeze Protection Cooler Heaters:
Cooler heaters shall provide protection from
cooler freeze-up to –20 F (–29 C).
18. Value Sound Fans:
Shall provide propeller-type fans for applica-
tions that are not highly sound-sensitive. These
fans shall have Class F insulation and internal,
automatic-reset thermal overload protection or
manual reset calibrated circuit breakers.
19. Ultra-Low Sound:
Shall provide an acoustic enclosure around
each compressor in conjunction with low-sound
Aero-Acoustic™ fans to provide significant
chiller sound reduction.
20. High SCCR (Short Circuit Current Rating):
The optional high SCCR (short circuit current
rating) device shall allow the chiller to tolerate a
65 kA (208/230, 380 and 460-v units) or
25 kA (575-v units) short circuit current for a
brief period of time while protecting down-
stream components. The high SCCR option
shall provide a higher level of protection than
the standard unit.
21. Compressor Suction Service Valves (Sizes 070-
090 only):
Shall provide a suction service valve per circuit,
which is in addition to the standard discharge
service valve.
22. Digital Compressor Option:
Shall provide a factory-installed digital compres-
sor to provide incremental steps for tighter tem-
perature control (not available on size 018
units).
23. Remote Cooler Kit:
Field-installed remote cooler kit shall provide
the additional hardware required to remotely
mount the cooler from the unit. There are limits
to total separation of the unit to the cooler as
well as vertical separation limits, and these shall
be delineated in the accessory installation
instructions. Never bury refrigerant piping on
these or any other applications.
24. Wind Baffles:
Wind baffles facilitate operation down to
–20 F (–29 C) when used in conjunction with
low ambient temperature head pressure
control.
25. Low Sound Compressor Blankets:
Accessory low sound compressor blankets shall
reduce unit sound levels by providing an acous-
tic blanket on each compressor.
