SYSTEM START-UP AND OPERATION
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. Before repositioning valve(s) and before beginning the assembly, disassembly, or adjustment of the clamp or any other service of
the circulating system: (A) Turn the pump OFF and shut OFF any automatic controls to ensure the system is NOT inadvertently
started during the servicing; (B) open the manual air relief valve; (C) stand clear of the filter; (D) wait until all pressure is relieved.
2. Whenever installing the filter clamp FOLLOW THE FILTER CLAMP INSTALLATION INSTRUCTIONS EXACTLY.
3. Once service on the circulating system is complete FOLLOW SYSTEM RESTART INSTRUCTIONS EXACTLY.
4. Maintain circulation system properly. Replace worn or damaged parts immediately, (e.g., clamp, pressure gauge, valve(s),
O-rings, etc).
5. Be sure that the filter is properly mounted and positioned according to instructions provided.
The following information should be read carefully since it outlines the proper manner of care and operation for your filter system. As a
result of following these instructions and taking the necessary preventative care, you can expect maximum efficiency and life from your
filtration system.
Opening the Filter
Follow these instructions exactly
to prevent the lid from separating during system start-up, operation or servicing.
REQUIRED TOOLS:
• Ratchet Wrench
• 7/8” Socket
• Socket Extender (if needed)
PROCEDURE:
1. Shut off pump and relieve pressure.
a. Turn the pump OFF, shut OFF any automatic
controls (e.g., timers), and disconnect power to
ensure that the system is not inadvertently started
during maintenance.
b. Open the HiFlow™ Manual Air Relief Valve
by turning the valve cover assembly counter-
clockwise until it snaps into the full open position.
c. Stand clear of the filter and wait until all pressure
is relieved. Pressure gauge must read zero (0 psi).
2. Open the waste drain plug on the bottom of the
FullFloXF
®
4000-Series D.E. Filter. Allow all water to
drain from the bottom of the filter tank.
3. Loosen the clamp's barrel nut with a 7/8" wrench,
allowing the spring coils to decompress. See
Figure 6
.
Remove the barrel nut, spring and two washers from
the T-bolt and place them in a safe place where they
will not be lost.
4. Once the spring has fully decompressed the clamp
assembly will rest in the open position. Carefully lift the
filter lid straight up from the lower body of the filter. If
the lid is tightly sealed to the filter body you may have
to gently push the filter lid from side to side in order to separate the lid from the tank bottom.
5. Place the tank lid in a safe place where it will not be damaged while performing any maintenance.
Note:
Attempt to minimize the amount of debris that comes in contact with the tank O-ring while it is exposed. This
will help prolong the life of the O-ring.
DO NOT use the relief valve as a handle or lever since this may damage the valve.
