8.1 Please note for the first operation
To prevent unnecessary strain on piping system and valves always shut off pump
before switching filter control 4 position valve positions.
All inlet and outlet valves must be open when starting the system. Otherwise this can
cause severe damage of the pump.
1. Press the top mount 4 position valve handle down and rotate to backwash position
2. Prime and start the pump according to these instructions.
3. Once water flow is steady out the waste line, run the pump for at least 2 minutes. The initial back-
washing of the filer is recommended to remove any impurities of fine sand particles in the sand
media.
4. Turn pump off and set valve to rinse position. Start pump and operate until water in sight glass is
clear - about ½ to 1 minute. Turn pump off, set valve to FILTER position and restart pump. Your
filter is now operating in the normal filter mode, filtering particles from the pool water
High suction lift or long suction hoses require additional time and reduce the perfor-
mance of the pump. If the pump does not prime, repeat steps 1 and 2.
Note:
Regular maintenance of the pump and sand filter extends the life cycle of the pump and increases the
efficiency.
If the water level to be dropped in the sand filter tank, you should fill up the tank again before recom-
missioning.
1. Remove the translucent lid and fill the filter tank with water.
2. Replace the lid ensuring the o-ring is correctly located and start the pump.
After you have done this allow a few minutes (maximum) running for the pump to start delivering
water.
8.2 Functions of the 4-position valve of the sand filter:
Filter – Set valve in position filter for normal filter operation.
Backwash: for cleaning the filter. When filter pressure gauge raises 0.5 bar above start-up, a cleaning
of the filter must be done:
Stop the pump, set valve to backwash. Start pump and backwash for approximately 2 minutes or less
depending on dirt accumulation. Proceed to rinse.
Rinse After backwashing, with pump off, set valve to rinse. Start pump and operate for about 1 mi-
nute. This ensures that all dirty water from backwashing is rinsed out of the filter to waste, preventing
possible return to the pool. Stop pump, set valve to FILTER and start pump for normal filtering.
Winter position – All valves are opened. In this position the pressure on the sealing's is re-
lieved.
9. Maintenance and care
Prior to carrying out any maintenance work, the pump must be separated from the
electrical mains. If you fail to separate the unit from mains, there is a risk of an inad-
vertent start of the pump.
We decline any liability for damage caused by inappropriate repair attempts. Any
damage caused by inappropriate repair attempts will avoid all warranty claims.
Observing the conditions of use and the ranges of application of the present device will reduce the risk
of possible operational malfunction and contribute to extend the lifetime of your unit. Sand and other
abrasive matters contained in the liquid discharged will speed up the process of wearing and tearing
and accelerate the drop in performance.
The user must ensure that maintenance is done from qualified persons, who have carefully read all
instructions for installation and maintenance. In case the set is not used for a longer period, the pump
and filter tank must be drained. Frozen water inside the pump and filter tank can cause severe dam-
