Cartridge style d.e. filter

Table of Contents

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.

FILTER OPERATES UNDER HIGH PRESSURE.

When any part of the circulating system (e.g., Clamp Ring, Pump, Filter, Valves, etc.) is serviced, air can enter the system

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.

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

Q-Series Cartridge Style 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.

DO NOT use the relief valve as a handle or lever since this may damage the valve.

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.
