OPERATION
TROUBLESHOOTING
TO SET FILTER PUMP TIME SWITCH, follow
instructions on the right. The length of the daily filtration/
heating cycle depends on many variables such as size, shape,
geographic location of the pool, water chemistry, type of
pool equipment, usage and season of year. If not sure,
contact your local pool service professional for advice.
THE FIREMAN SWITCH (Heater Protection Mechanism),
if required, is factory set and shuts OFF the heater 20
minutes before the Time Switch turns OFF the filter pump.
The Fireman Switch requires no setting or service.
