Operation:
The equipment mainly performs the water filtration function as described in this manual.
For the correct functioning of the filter and the correct management of the system to which it is connected, other functions are foreseen.
These functions take place through a different setting of the 6-way valve connected to the filter (supplied with the filter).
The valve has 6 positions: Filtration, Backwash, Rinse, Waste, Circulation & Closed.
The operating conditions for each position are detailed below.
CAUTION:
The selection of the 6-way valve lever must be carried out ONLY AND EXCLUSIVELY with the pump TURNED OFF.
Filtration
It is the normal operating position, performs the function of filtering the pool water between the inlet and the outlet of the filter.
Observe the pressure gauge regullarly, it is recommended to proceed with the backwash operation when the pressure exceeds 1,1 kg/cm2.
Backwash
It is used to clean the filteration media by removing the retained parts during normal operation.
Recommended operation time: 2-3min
It is recommended to do a backwash every week and immedaitely after a vaccum cleaning of the pool.
Rinse
It is an operation to be carried out after backwashing to remove any impurities left inside the valve.
Recommended operating time: 1 min
Circulation
It is the position that allows the system to operate without the filter function. The water is bypassed directly to the outlet.
Waste
It is the position of by-passing the inlet water directly to the drain (e.i. pool emptying).
Closed
It is the position that closes all the valve passages.
Winterizing
It is an intermediate position (0) which, with an empty system, allows to prevent possible freezing failures.
Start-Up:
- Once the sand filter has been loaded, it is necessary to backwash it and proceed as follows:
- Slightly unscrew the air vent plug located on the cover without removing it,
- Place the selector valve to the Backwash position to clean the filtration media the first time,
- Open the valves that control the suction lines and drain, turn on the pump for 2 minutes,
- Turn off the pump and place the selector valve handle in the Filtration position,
- Close the air release plug just after water starts coming out,
- Once this operation is done the filter will be ready to start the pool water filtration cycles.
IMPORTANT: Perform the position changes of the selector valve handle with the pump always in OFF position.
Maintenance:
To clean the external surface of the filter, do not use dissolvents, as this can damage it and eliminate the brightness of the same.
When necessary, the O-Rings and the damaged parts must be replaced.
Perform the necessary backwashes and rinses according to the operating instructions.
During winter, it will be necessary to carry out the following operations:
- Carry out a Backwash according to the previously indicated instructions.
