The water flows back from the swimmer tank to the
suction side of the pump. The water level in the swim-
mer 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 water 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 sen-
sor. After that, there will be the high-pressure network
of the operator.
Remaining water will be routed back to the floater ba-
sin 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 output exceeds the maximum operating pres-
sure 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.
The first pump is switched on via the frequence in-
verter, all remaining pumps are operated directly
via the mains.
–
If the flowmeter 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 when the preset
time has elapsed.
Safety devices serve for the protection of the user
and must not be put out of operation or bypassed with
respect 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 proctection 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 flowmeter 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.
