FUNCTIONS OF THE MULTI-WAY VALVE POSITIONS
FILTER
Normal filtration, 6-8 hours a day. Water circulates via the pump and filter sand and back into the swimming
pool. The swimming pool vacuum cleaner is also used in this position.
BACKWASH
Washing of the filter sand. If the pressure gauge shows a pressure 70 kPa above the initial pressure at the
start of the cycle, the filter needs washing. Procedure: switch off the pump, turn the valve control lever to the
position BACKWASH, switch on the pump and let it run until clear water comes out of the waste pipeline. This
must be followed by a rinse.
RINSE
Rinsing of the filter after washing. Procedure: switch off the pump, turn the valve control lever to the position
RINSE, switch on the pump and let it run for about 10-20 seconds. This will settle the sand and pump the rest
of the dirty backwash water into the waste pipeline and prevent it being sucked back into the sand. Then
switch off the pump, put the valve control lever in the position FILTER and switch on the pump again.
WASTE
A bypass of the filtration vessel. Used for reducing the water level in the swimming pool, emptying the
swimming pool or, when using a vacuum cleaner, for moving larger quantities of impurities from the swimming
pool directly into the waste pipeline.
RECIRCULATE
Water circulation outside the filter. The water circulates via the filtration assembly outside the filtration vessel
with filter sand. This is used, for example, for faster dissolution of swimming pool chemicals.
CLOSED
Closes the water flow from the pump to the filter.
NEVER SWITCH ON THE PUMP IN THIS VALVE POSITION.
WINTERIZING
1. Unscrew the drain plug (13) and drain the water from the filter vessel. Do not replace the plug; store it
safely.
2. Press the valve control lever and turn it to an intermediate position or to the position OPEN/WINTER if
present on the valve. This will permit water to drain from the valve as well. Leave the control lever in this
“open” position.
3. Drain and winterize the pump according to the pump operating manual instructions.
