BACKWASH OPERATIONS
1. Carry out the backwash procedure as follows:
2. Turn OFF the power to the pump (with power supply or (FIL = OFF, POL = OFF and SPA OFF)).
3. Prepare the system for backwash and power ON the pump (with power supply or (FIL = ON)).
4. The circulating pump will go ON and the controller will not check for 5 minutes if water flow is present at the
flow switch.
5. You will have 5 minutes of uninterrupted water flow to do the backwash.
6. Stop the circulating pump (use the power supply or FIL=OFF).
Normally, when the circulating pump is required for this operation and there is no water flow detected at the control,
the pump will automatically turn OFF. This procedure will give a 5 minute period of uninterrupted water flow before
the circulating pump turns OFF.
