Flow Switch Function

The above precaution pertains to Input ‘F’ lockouts as well as the integral flow switch on input ‘E’. If

disabled or bypassed, the sensor would not be able to sense a hazardous situation and turn of the

chemical feed pumps to prevent uncontrolled chemical feed.

Test Flow Switch Function

Chemical Feeders

NEVER OVERRIDE A FLOW SWITCH

Uncontrolled feeding of concentrated chemicals can result in personal injury

or death. Sample and recirculation flow switches are critical safety devices

which prevent uncontrolled chemical feed. Follow Instructions Carefully.

Flow switches are provided with all ProMinent pool controllers and are an

integral safety device to prevent the uncontrolled feed of chemicals, which

could cause personal injury or death. This critical safety device must always

be available to protect the swimmers and others near the pool.

Flow switches should NEVER be bypassed, even temporarily.

If flow switch

‘float’

does not

drop to the bottom

and remain

there

during no-flow, backwash, or very low flow conditions, the

controller cannot prevent the uncontrolled feed of chemicals,

which could cause personal injury or death.

Testing of the flow switch installation is essential to assure the

flow switch stops, remains stop

ped, and controller shows

“SensorFlow ALARM” within 20 seconds, whenever filter is in

backwash or circulation flow stops. If the flow switch does not fully

drop, plumbing corrections or the installation of additional

safeguards will be necessary to avoid uncontrolled chemical feed.

NEVER CONNECT FEEDER DIRECTLY TO POWER SOURCE

If the chemical feeders are connected to a wall outlet, the safety

devices integral to your ProMinent controller, and to the safe

feeding of chemicals, will be bypassed. It is very important that

the chemical feeders be connected to the controller and never

directly to a wall outlet. If the chemical feeders are connected to a

wall outlet and feeding continuously, when the flow of water to the

pool stops due to filter backwash, the circulation pump losing

prime or other causes, potentially hazardous concentrations of

chemicals can be fed into a pool or spa. Follow Instructions

carefully to insure safe operation.
