• Run the pump and from the pre-filter lid check that the pump is fully primed for no more
than 12 minutes.
• The motor guard circuit breaker's current may not exceed the nominal value displayed on
the pump's rating plate by more than 15%.
• The variable-frequency drive's output frequency range must be 20–50 Hz. The pump must
not be used outside of this range.
• Check that all units installed in the pool are able to work properly when the pump is run-
ning at low speed (20 Hz).
4. MAINTENANCE
Depending on how clean the water is, the following should be checked every 150 hours:
- Clean the prefilter basket to avoid pressure drops. Do not hit the basket during the cleaning
process as this could potentially damage it.
- Every time the prefilter is opened, clean off any dirt on the seal and its housing to ensure
the cover is watertight when closed (FIGURE 9).
The pump components that are prone to wear and tear through routine use must be regularly replaced
for the pump to maintain good performance. The pump's fungible components or consumables are
listed in the table below along with the time when they should be replaced.
DESCRIPTION OF THE COMPONENT
Capacitor
Bearings
Mechanical seal
O-rings and other seals
Opening and closing the pump to replace internal parts does not guarantee subsequent water
(1)
tightness. Therefore, it is recommended that O-rings and other seals be replaced whenever the
mechanical seal and/or bearings are replaced.
The service life of the above components has been calculated based on the pump's normal conditions
of use, installation and maintenance as described in this pump's manuals.
Follow the instructions in this pump's manuals to ensure it works properly.
