System Start-Up And Operation; Opening The Filter - Pentair FULLFLOXF C Series Installation And User Manual

Cartridge 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.

This filter operates under high pressure. Air can also enter the system and become pressurized.

If there is air in the system, there will be positive pressure that could cause the lid to separate from the filter when you

release the clamp or during system start-up or operation (see Important Warnings and Safety Instructions, page i-ii).

If there is no air in the system, there may be negative pressure, which would make the system hard to open.

Follow these instructions exactly - opening the relief valve equalizes the pressure and releases any trapped air within the system, making

it safe and easy to open.

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

C-Series Cartridge 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.
