The most common PROBLEMS
EFFECT
The filter only provides a small volume
of the filtered water.
Vacuum heads have poor suction.
The pressure gauge varies
considerably.
SAFETY WARNINGS
Never start up the system without water.
Whenever you operate the filter or the selector valve, switch off the pump first.
Never allow children or adults to sit on the system.
Do not connect the filter directly to the water network, as the pressure of the water may be too high and exceed the
maximum work pressure allowed by the filter.
Do not use the filtering circuit to fill and adjust the water level of the pool. A handling error may lead to overpressure in the
filter.
Do not clean the lid with solvents, as it may damage its properties (finish, transparency ...).
As all the connections are made with joints, it is not necessary to tighten the nuts excessively in order to avoid that some
plastic pieces could break.
DO NOT use teflon in the T-part of the pressure gauge Kit, code 00545R0300, to ensure sealing.
POSSIBLE CAUSE
Prefilter blocked.
Motor turning the wrong way.
Suction pipes are blocked.
The pump is taking in air.
Suction is half closed.
SOLUTION
Clean filter.
Check by the arrow on the body of the
prefilter which way the motor is
turning, if this is not correct, reverse
the motor connection.
Proceed to clean.
Check for leaks in the prefilter and
suction pipes.
Check that the suction valves are
completely open.
