ACCESSORIES
(
SHIPPED LOOSE FOR FIELD MOUNTING)
Water Flow Switch (WFS) - paddle type field
adjustable flow switch. Must be tied into the unit safety
circuit so that the package will remain off until water
flow is proved. Helps prevent cooler freeze up. NEMA
3R enclosure, for use on water, ethylene or propylene
glycol circuits.
Spring Isolators (SPG) - designed for 1" deflection,
these housed spring assemblies have a neoprene friction
pad on the bottom to help prevent the passage of noise
and a spring locking leveling bolt at the top. Neoprene
inserts prevent contact between the steel upper and
lower housings. Suitable for more critical applications
than RIS isolators.
Rubber-in-shear Isolators (RIS) - designed for
ease of installation, these rubber, one piece, molded
isolators have skid resistant baseplates. Applicable for
most installations.

bell to be mounted remote of the unit and wired to the
ALC common alarm contacts in the unit by others.

communications via the RS232 connection port, for
complete operation of the packaged chiller, including
graphing information, up to 100 feet (30 meters) from
the packaged chiller. The PCONN software will be
provided for use with a remote PC by others. See
connection diagram page 12.
PC Connection Enhanced (PCCE) - Provides
communications via the RS485 connection port, for
complete operation of the packaged chiller including
graphing, up to 6000 feet (1829 meters) away. This
option includes the addition of a gateway to convert
the RS485 port of the
to RS232, which
then may be connected to a modem or directly to a PC.
One additional feature is that a field supplied and
installed AB switch can be added to allow switching
between a local PC and a modem. The gateway and
PCONN software will be supplied for use with a remote
PC by others. See connection diagram page 12.
