Start-Up Instructions
THIS FILTER OPERATES UNDER HIGH PRESSURE.
When any part of the circulating system, (e.g., clamp, pump, filter, valve(s), etc.),
is serviced, air can enter the system and become pressurized. Pressurized air
can cause the lid to separate which can result in severe injury, death, or property
damage. To avoid this potential hazard, follow these instructions:
1. Be sure the spring on the clamp ring is fully compressed, with coils touching.
2. Open the HiFlow™ Manual Air Relief Valve by turning the valve cover assembly
a quarter turn counter-clockwise, until it snaps into the full open position. See
Figure 8.
3. Stand clear of the filter tank, 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-flow appears.
b. A solid stream of water does not appear within 30 seconds after the pump's
inlet basket fills with water.
c. Water leaks from where the two halves of the filter come together.
If any of these conditions exist, shut off the pump immediately. Open the manual
air relief valve to relieve pressure and clean the valve (see Cleaning the Manual
Air Relief Valve, page 12). 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 first time the system is started up, fill out Table 3:
a. Record the "Original Starting Pressure"
b. Fill in the pressure at which to clean the filter (8-10
psi higher than the "Original Starting Pressure").
c. If the system includes a variable speed pump,
record "Original Pump RPM". "Original Starting
Pressure" will be dependent on the pump speed
(RPM).
