MULTICYCLONE PLUS/ULTRA / FILTER MAINTENANCE
The MultiCyclone Plus/Ultra lter maintenance is determined by the following conditions:
1. The sediment chamber is half lled with sediment. This accumulation of sediment can
be visibly monitored through the MultiCyclone Plus/Ultra’s clear sediment chamber. The
MultiCyclone Plus/Ultra is cleaned by simply opening the purge valve. Only 15 litres (4
gallons) of water is discharged to clean the MultiCyclone of sediment.
2. A pressure gauge reading of 50kPa (7.2psi) above the operating pressure may result in a
reduced ow rate that is insufcient to meet the requirements of the pool.
Example: Filter operates normally at 60kPa (8.2psi) needs to be cleaned at 110kPa (16psi).
Flush out the sediment chamber
With pump running:
Whilst the water pump is running simply open the sediment purge valve until the sediment has
been ushed out. This is visible through the clear sediment chamber. Once the sediment has
been ushed out, close the purge valve.
Without pump running:
Alternatively, switch the pump, off. Open the air release valve and then open the purge valve.
The water will drop through the MultiCyclone Plus/Ultra ushing out most of the debris from the
sediment chamber. Then close the air release valve and turn on the pump and the turbulence
of the water entering the sediment chamber will ush out the rest of the sediment. Once the
sediment chamber has been cleansed, close the purge valve, start the pump and close the air
release valve once water is owing out through the air release valve.
INSUFFICIENT WATER PRESSURE
In situations where the water ow from the pump is not powerful enough purge the sediment
out of the sediment chamber. Waterco recommends tting a 2 way valve after the MultiCyclone
Plus/Ultra on the pool water return line.
The 2 way valve is used to throttle the ow of water out of the MultiCyclone Plus/Ultra, increasing
water turbulence through the sediment chamber and improving its purging action.
Whilst the pump is operating, open the purge valve, and then partially close the 2 way valve,
throttling the water ow sufciently to purge the sediment chamber of trapped sediment. Once
the sedimement chamber is clean, open the 2 way valve and then close the purge valve.
Do not close the 2 way valve prior to opening the purge valve and do not close the purge
valve while the 2 way valve is closed or partially closed. Both valves should never be
closed or partially closed at the same time.
