Guide To Cleaning Your Sand Filter

09 June 2020

 by Angus Donald

Here's a general guide to help you clean your sand filter.  Please note, this guide should be read in conjunction with the relevant user manual for your individual pool equipment. Active Pool Supplies takes no responsibility for the incorrect operation of your pool equipment.
Different systems will have differing methods to turn off the power to the pool pump. In some cases, this can be done at the chlorinator (e.g. ON/OFF/AUTO switch). In other cases, it might be done by turning the power off at the power point, when required.

When a Viron chlorinator is in use, the SAFETY BACKWASH feature can be used, after the POOL MODE switch is set to OFF.

ENSURE THE LEVEL OF WATER IN THE POOL IS ADEQUATE.

NEVER ATTEMPT TO TURN THE FILTER HANDLE WHILST THE PUMP IS RUNNING.

CLEAN SKIMMER AND PUMP BASKETS FIRST AND REMOVE VACUUM PLATE TO ENSURE BACKWASHING WITH CLEAN WATER.

1. Turn pump and cell off - At the chlorinator, if possible, or at the power point.
2. Turn filter handle to BACKWASH
3. Turn pump back on.  
a. If a Viron chlorinator, press SAFETY BACKWASH 1, 2, or 3 times to run pump for 1, 2 or 3 minutes.
4. Allow pump to run and send water up thru the sand to remove dirt, debris and bacteria down the waste line until the water going through the sight glass is clean.
5. Turn pump off.
6. Turn filter handle to RINSE.
7. Turn pump back on.  
a. If a Viron chlorinator, press SAFETY BACKWASH once to run pump for 1 minute.
8. Allow pump to run for 30 secs to one minute or until sight glass is clear.  Water is sent back down thru the sand and down the waste line to remove any debris at bottom of sand.
9. Turn pump off.
10. Turn filter handle to FILTER.
11. Turn pump and cell back on - either at power point or at the chlorinator (re-set to AUTO if required).

CHECK THAT THE CURRENT TIME ON THE CHLORINATOR IS CORRECT - ADJUST IF NECESSARY.
