Entering Filtration Mode
The initial step in the filtration mode is the precoat process. A precoat cycle will automatically begin whenever the control
panel filter switch is turned on. Once the precoat cycle is complete, the filter will automatically advance to filtration mode.
The system is now recirculating and filtering water from the pool.
1.
Examine and record the filter inlet and outlet pressures. The difference between the two readings is the system
’s
initial differential pressure.
NOTE
It is recommended that a PowerBump be performed at least once every day, or if the pressure differential reaches 12 PSI. Depending
on the bather load, PowerBumping might be required more frequently.
Performing the Power Bump Sequence
The PowerBump process reverses water flow through the flexible tube elements, forcing perlite and accumulated debris
off the tubes and into suspension.
1.
Push the PowerBump button on the control panel to initiate the process.
2.
Precoat valve V5, will open.
3.
Effluent valve V1, closes.
4.
Valve V2 opens, valve V3 closes, and valve V4 opens.
After 40 seconds the valves will change state to begin a 10-minute precoat process prior to returning to filtration mode.
Recharging the Media
Depending upon bather load and other factors, the media might require recharging anywhere between 2 weeks and 3
months. The exact frequency will become apparent as operating experience with the system increases. The following are
good indicators to determine when it is time to recharge the media:
•
Pressure differential returns to 10-12 PSI shortly after bumping.
•
Design flow rate for the system cannot be maintained.
Perform the following steps to recharge the media:
1.
While still in Filter Mode, partially open drain valve V9 to clear any debris from the pipe then close the valve.
2.
Press the PowerBump button on the control panel and allow approximately 40 seconds for the system to enter
Precoat mode.
3.
Turn the Filter switch to the OFF position. Confirm the pump is off.
4.
Close pump discharge throttling valve F7.
5.
Open drain valve V9.
6.
Open vacuum drain valve V7 to increase drainage flow.
7.
Once the tank is completely drained, close the drain valve V9.
8.
Refill the tank with water by opening discharge throttling valve F7. If the filter is above grade, you will need to start
the pump manually.
9.
Repeat steps 4-8 to drain the tank and rinse again.
completed, the unit is ready to be started. For start-up to work properly, shut down
