Lock Ring Installation Instructions
These instructions MUST BE FOLLOWED EXACTLY to prevent the lid from separating during system restart or
later operation.
1. Perform the following steps before working on any part of the circulating system (e.g., lock ring, pump, filter,
valves, etc.).
a. Turn the pump off and shut off any automatic controls to ensure that the system is not
inadvertently started during servicing.
b. Open the High Flow™ manual air relief valve.
c. Wait until all pressure is relieved.
Never attempt to assemble, disassemble or adjust the filter
lock ring while there is any pressure in the filter.
2. Be certain the O-ring is in position in the lower tank half. Place the filter lid over the lower tank half, making
sure it is fully and firmly seated on the tank half, see
Figure 2
.
3. Place lock ring over the tank lid, and centering the lock ring on the threads of the tank body. Turn the lock
ring clockwise until the safety latches click and the lock ring hits the stops on the body. DO NOT ATTEMPT
TO OVER-TIGHTEN THE LOCK RING AFTER LOCK RING HAS HIT THE STOPS ON THE BODY.
4. Follow the
Startup Instructions
below.
Startup Instructions
1.
Open the High Flow™ manual air relief valve until it snaps
into the full open position (this only requires a quarter turn
counterclockwise
). Opening this valve rapidly releases air trapped in
the filter.
2. Stand clear of the filter tank, then start the pump.
3. Close the manual air relief valve after a steady stream of water appears.
4. The system is not working properly if either of the following conditions
occur.
a. A solid stream of water does not appear within 30 seconds,
after the pump’s inlet basket fills with water.
b. The pressure gauge indicates pressure before water outflow
appears.
If either condition exists,
shut off the pump immediately
, open valves
in the water return line to relieve pressure, and clean the air relief valve,
see
Cleaning the Manual Air Relief Valve
on page 4. If the problem
persists, call (800) 831-7133 for assistance.
OPERATION
THIS SYSTEM OPERATES UNDER HIGH PRESSURE.
When any part of the circulating system (e.g., Lock Ring, Pump, Filter, Valves, etc.) is serviced, air can enter the sys-
tem and become pressurized. Pressurized air can cause the lid to separate which can result in serious injury, death,
or property damage. To avoid this potential hazard, follow the instructions below.
