WARNING

Before Starting the Pump

1. Use ONLY original components. Non-original clamp

components may fail in use and cause explosive

component separation. Verify that upper and lower filter

bodies are properly secured with the filter body clamp.

Never rely on hand tightening the clamp nut to the clamp

bolt. Using a ¾" socket on a torque wrench, torque clamp

nut to clamp bolt to 150 inch-lbs. (See Figure 1) Verify that

the filter manual air relief body is in the LOCK position,

and no filter components are missing, damaged or not

genuine AquaGuard components. (See Figure 2)

2. Close filter drain.

NOTE: Filter plug requires an O-Ring seal (See Figure 4)

2. Open all system valves to allow water from the pool to the

filtration system and from the filter to return to the pool.

4. OPEN the manual air relief valve. (See Figure 2)

Starting Pump

1. When starting system pump, do not stand over/near filter.

If water leakage appears at filter tank clamp, immediately

turn off all system circulation pumps and all electrical

power. Do not return to the filter until all water leakage

has stopped. Reassemble the clamp system per the

instructions on page 7 in this owner's manual to stop leak.

2. Return to filter to CLOSE manual air relief valve only when

a steady stream of water (not air or, air and water mix) is

discharged from the manual air relief valve.

Filtering

Filtration starts as soon as flow is steady through the

filter. As the filter removes dirt from the pool water, the

accumulated dirt causes a resistance to flow. As a result, the

gauge pressure will rise and the flow will decrease. When

the pressure rises between 7 - 10 PSI above the starting

pressure, or when the flow decreases below the desired rate,

clean or replace the filter cartridge elements. Once your filter

is running and there is a pressure reading, line up the green

arrow with the current reading. (See Figure 3) When the

pressure rises to or above the red or second arrow, it is time

to clean or replace your filter cartridge elements.

By recording the initial starting pressure (with clean filter

elements) a determination can be made when the filter

cartridge elements should be replaced rather than cleaned.

After the filter elements have been cleaned and reinstalled if

the starting pressure is higher than 6 PSI above the starting

pressure with the new filter cartridge elements, the filter

cartridge elements should be replaced the next time the

gauge arrow reaches the red arrow.

Maintaining Your Filter

WARNING: Product should be

installed/serviced only by a

qualified pool professional.

Filter Disassembly Instructions

1. Turn off all system circulation pumps and all electric

power on the equipment pad.

2. Set all system valves to prevent water flow to the filter.

3. The manual air relief valve must be placed in the OPEN

position. (See Figure 2)

4. Remove filter drain plug (See Figure 4) and drain water

from filter.

5. Using ¾" wrenches or hex sockets, loosen and remove the

clamp nut and the clamp bolt. (See Figure 1)

6. Holding both ends of the filter clamp carefully spread the

clamp ends. Remove the clamp by lifting over the upper

filter body. Do not to drop the clamp during removal,

because the clamp could be damaged. Do not strike the

clamp with metal tools as they can damage the clamp.

7. Lift off upper filter body. Do not use the pressure gauge to

lift the upper filter body.

Filter Disassembly Instructions

1. Remove the top Manifold, which is exposed when the

upper filter body is removed. (See Figure 4)

2. Remove the filter cartridge elements by using slight

rocking motion and lifting up.

3. Clean filter cartridge elements
