ELECTRICAL SURGES CAN DAMAGE YOUR
CONTROLLER
Uncontrolled feeding of chemicals can result in injury or death.
A damaged controller could feed chemicals in an uncontrolled
manner.
If you suspect your ProMinent controller is not operating properly,
disconnect it from the chemical feeders until the problem has been
corrected.
seconds. If not, plumbing corrections or the installation of additional safeguards will be necessary to avoid
dangerous uncontrolled chemical feed.
Chemical Feeders
Electrical Surges
ProMinent controllers, like all modern electronic devices can be damaged by severe electrical spikes and
surges, like lightning. Every effort has been made to harden your controller against such surges, but no
precautions are 100% effective. Additional surge protection can be installed at time of installation, but
even that is not a guarantee that surge damage will not occur. If surge damage occurs, chemicals could
be fed to your pool or spa, continuously with no safety controls. If you inspect your ProMinent controller
after a possibly damaging power surge (thunderstorm or power outage) and suspect the controller is not
operating properly, disconnect the chemical feeders at once, and contact your ProMinent dealer for
service.
NEVER CONNECT FEEDERS 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.
ALWAYS USE ANTI-SYPHON DEVICES
Uncontrolled feeding of chemicals can result in injury or death.
Anti-Syphon devices must be installed on chemical feeders to prevent
uncontrolled feed of concentrated chemicals.
If a vacuum is created in the water circulation line and no anti-siphon
device is installed on the chemical feeders, potentially hazardous
concentrations of chemicals can be drawn into pool or spa. Always use
injection check valves and anti-siphon valves in the chemical feed lines to
prevent this situation from occurring.
