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, to ensure sealing.

POSSIBLE CAUSE

Prefilter blocked.
Motor turning the wrong way.
Suction pipes are blocked.
The pump is taking in air.
