a) Place cover on flow switch making sure

the test lever is protruding through the

appropriate slot in the cover. Check to

make sure the lever doesn’t bind with

Observe that the dependent boiler

device is being activated by the flow

switch to determine if the flow switch is

operating as required.

dependent device changes state, returning

to its original condition.

d) Repeat steps b and c several times.

e) If system operation is correct, turn on

system fluid flow and push the manual

test lever down as shown in figure 2.

Observe the dependent device changing

state.

f) Release the test lever and observe the

system returning to its original state.

g) Repeat steps e and f several times to

test the flow switch and its dependent

device for proper operation.

If the flow switch does not operate properly
