a.

Place cover on flow switch and turn on power. Initiate 
fluid flow through the system. Observe the device being 
activated by the flow switch to determine if device is 
operating as required.

b.

Turn off fluid flow to determine if device is operating 
as required.

c.

Repeat initiating and turning off fluid flow several times to
test flow switch and device for proper operation.
- If operating as required, put system into service.
- If not operating as required, flow switch may need 

to be adjusted.

ADJUSTMENT

Adjustment is necessary only if required flow/no
flow setpoints are above factory set minimum.

a.

Turn off power.

b.

Locate adjustment lever on bottom of unit.
Note that lever will be perpendicular to flow 
switch body.

c.

Loosen adjustment lever screw but DO NOT 
REMOVE.

d.

Turn adjustment lever counter-clockwise to 
increase setpoint. Maximum setting is with 
adjustment lever parallel with flow switch body.

e.

Tighten adjustment lever screw.

f.

Turn on power.

g.

Test the operation of the flow switch after 
each adjustment.
