1.2 DESCRIPTION OF CIRCULATION PUMP
The circulation pump is used to pump the water from the swimming pool through the filter tank and back into
the swimming pool (see also enclosed separate pump manual).
1.2.2 SHAFT SEAL
The pump is equipped with a mechanical seal bet
-
ween the pump housing and the motor to seal the
motor shaft. This seal is a wearing part/no warranty
(see pump 4.2.3).
1.3 DESCRIPTION OF FILTER TANK
The filter tank is used to mechanically remove
suspended particles such as hair, skin flakes, pollen
and other impurities from the swimming pool water
by means of a special quartz sand for swimming
pools (0.4 - 0.8 mm or other filter medium, e.g. filter
glass or filter balls). This is done at a pressure of
0.4 - 0.8 bar. When the pressure increases (loud
pumping noise) the filter must be backwashed (see
section 2.4). This is by no means a defect of the
pump, it is a normal process, as the pump has to
work against a higher resistance if the filter tank/
filter sand is too dirty. To measure the filter pressure
in the tank, there is an optional pressure gauge
(item no.: 2600020) available (not included in deli
-
very), which is fixed at the top of the valve (bleeder
screw). The pressure gauge allows you to read
the filter pressure at any time and thus determine
whether a backwashing is required. If you do not
have or use a pressure gauge, we recommend
backwashing once a week.
