FLOW SWITCH FS10-C SERIES
GENERAL APPLICATION: AUTOMATIC CONTROL AND SAFETY DEVICE, NOT INTENDED FOR FIRE SPRINKLER SYSTEMS.
— Principally used in water systems, heating systems, air conditioning and processing installations.
— Single pole double throw switch can be wired to make one circuit or break a circuit when flow starts or stops.
— Actuates an alarm when flow is inadequate — deactivates alarm when sufficient flow is restored.
— Parts in contact with liquid in pipe are of brass and beryllium copper.
IMPORTANT: Electrical installation must be performed by a qualified person and in accordance with all local codes.
LOCATION: Flow switch should be installed in horizontal or vertical section of a pipe or tube where there is a straight run of at least 5
pipe diameters on each side.
MOUNTING: Flow switch should be installed vertically upright in tees or welded fittings.
If a reducing tee is not available and a standard tee
is used, install a face bushing in top opening to
keep waterflow indicator as close to tee as possible.
If a welded fitting is to be used, use only a half
coupling. (Make sure hole in main is 1-5/32" dia.
before welding coupling.)
NOTE: PADDLE LENGTH CONFORMS TO
ASTM TEE STANDARD.
USE PROVIDED TEMPLATE TO TRIM
PADDLE TO REQUIRED LENGTH “L”.
ACTUAL SIZE TEMPLATE TO TRIM DIMENSION “L”
Always check operation of flow switch to make sure paddle
is free to move in the tee, coupling or pipe before finishing
the installation.
“L” refers to trim length in table.

A. FINE SENSITIVITY
1. REMOVE SWITCH COVER.
2. FOR FINER SENSITIVITY, TURN
RANGE ADJUSTING SCREW
CLOCKWISE. LOCATED ON
LEVER NEXT TO MICROSWITCH.
B. COARSE SENSITIVITY
1. REMOVE SWITCH COVER.
2. FOR HIGHER FLOW RATE, TURN
RANGE ADJUSTING SCREW
CLOCKWISE. LOCATED WITH
ADJUSTING SPRING.
3. FOR LOWER FLOW RATE, TURN
COUNTER CLOCKWISE.

*Flow rates for these sizes are calculated.
PADDLE LENGTH: Included with each flow switch are four paddles. Shortest paddle (A) can be used for 1" pipe size only.
Second shortest paddle (B) can be used as is with paddle (A) for 2" pipe size; but must be trimmed for 1- 1/4" and 1-1/2" pipe size.
Third shortest paddle (C) can be used as is with paddle (A) and (B) for 3" pipe size, but must be trimmed for 2-1/2" pipe size.
Longest paddle (D) can be used as is with paddle (A), (B) and (C) for 6" pipe size, but must be trimmed for 4" and 5" pipe size.
