Start-Up Instructions
Follow these instructions exactly to prevent the lid from separating from the lter during system start-up or operation.
1. Ensure the spring on the clamp ring is fully compressed, with coils touching.
Refer to Reinstalling the Filter Lid and Clamp Ring, page 5.
2. Open the Manual Air Relief Valve by turning the top of the valve 1/4 turn
counterclockwise, until it snaps into the full open position. See FIGURE 7.
3. Stand clear of the lter, then start the pump.
4. Watch for proper operation. The system is not working properly if:
a. The pressure gauge indicates pressure before water out-ow appears.
b. A solid stream of water does not appear within 30 seconds after the
pump's inlet basket lls with water.
c. Water leaks from where the two halves of the lter come together.
If any of these conditions exist, shut o the pump immediately. Open the
manual air relief valve to relieve pressure and clean the valve. If the problem
persists, call Pentair Technical Service at (800) 831-7133 for assistance.
5. After a steady stream of water appears, close the manual air relief valve by turning
the valve cover assembly a quarter turn clockwise.
6. The rst time the system is started up, ll out TABLE 1 and the corresponding
label on the equipment:
a. Record the "Original Starting Pressure"
b. Fill in the pressure at which the lter should cleaned. This is approximately
10 psi higher than the "Original Starting Pressure".
c. If the system includes a variable speed pump, record "Original Pump
RPM".
ORIGINAL STARTING PRESSURE IS: ________ psi.
(pounds per square inch)
SERVICE THE CARTRIDGES AT: __________ psi.
ORIGINAL PUMP RPM: __________ RPM.
(for Variable Speed Pumps Only)
