The water flows back from the swimmer tank to the suc-
tion side of the pump. The water level in the swimmer
tank is kept constant by the swimmer valve. In case of
failure of the swimmer valve, the water exits via the
overflow. If the water supply is disturbed, the lack of wa-
ter fuse will send an error message to the controls.
The electric engine will drive the crankshaft pump. The
pump transports the water under high pressure to the
pressure side.
The high-pressure water reaches the high-pressure
output via the overflow valve and the pressure sensor.
After that, there will be the high-pressure network of the
operator.
Remaining water will be routed back to the floater basin
by the overflow valve. If all consumer loads have been
switched off, the overflow valve will completely switch to
backflow to the floater basin. If the pressure at the out-
put exceeds the maximum operating pressure at the
output, the safety valves will open.
– The appliance will be switched to READY mode by
activating the release switch. If the pressure in the
systems sinks below the determined switch-on
point due to the opening of a hand spray gun, the
high-pressure pumps will be switched on.
– If the flow switch at the overflow valve is triggered
while the high-pressure pumps are running after
closing all hand sprayguns, the pump is switched
off once again with a 30 second delay.
– If the system is ready and the high-pressure pumps
are not turned on, a timer is started, which will reset
the readiness of the unit after 6 hours.
Safety devices serve for the protection of the user and
must not be put out of operation or bypassed with re-
spect to their function.
The safety mechanism against lack of water prevents
the high pressure pumps from being switched on when
there is no water.
The temperature sensor switches off the appliance as
soon as the water temperature is too high.
The winding protection contact in the motor winding of
the pump drive switches off the engine when there is a
thermal overload.
– The safety valve opens when the overflow valve is
defective.
– The safety valve is set by the manufacturer and
sealed. Setting only by customer service.
– If all hand spray guns are closed, the overflow
valve opens and the entire water volume will flow
back into the floater basin. The high pressure
pumps are switched off via the flow switch once the
set delay time has elapsed.
– The remaining water flows back into the floater ba-
sin via the overflow valve.
If the hand spray gun is opened again, the high pres-
sure pumps will restart via the pressure sensor for high
pressure.
