CVGF-SVN02B-E4
Installation:
Mechanical
Flow switches must stop or
prevent compressor operation if
either system water flow drops
below the required minimum
that is shown on the pressure
drop curves. Follow the
manufacturer's
recommendations for selection
and installation procedures.
General guidelines for flow
switch installation are outlined
below.
• Mount the switch upright, with
a minimum of 5 pipe diameters
of straight, horizontal run on
each side.
• Do not install close to elbows,
orifices, or valves.
Note: The arrow on the switch
must point in the direction of the
water flow.
• To prevent switch fluttering,
remove all air from the water
system
Note: The CH530 provides a six-
second time delay on the flow
switch input before shutting
down the unit on a loss-of-flow
diagnostic. If machine
shutdowns persist, contact your
local Trane representative.
• Adjust the switch to open when
water flow falls below nominal.
Refer to the General Data
tables for minimum flow
recommendations for specific
water-pass arrangements. Flow
switch contacts are closed
when there is proof of water
flow.
