Pentair S8M600 owner manual Filter Cleaning Procedure

FILTER CLEANING PROCEDURE

NOTICE: When sanitizing your pool using PHMB (poly- hexamethylene biquanide based) cleaners, use only PHMB cleaners to clean the module. When using PHMB sanitizers, the filter module MUST be cleaned more thoroughly and frequently than for a pool using chlorine. Follow manufacturer’s instructions carefully. Use of any other type of cleaners with PHMB pool sani- tizers will void the filter’s warranty.

With hose, wash foreign material from inside of tank. Avoid washing debris into outlet port.

Be sure inside surface of tank is clean.

Keep track of filter operating pressure. When pressure reaches 10 PSI (70 kPa) above initial operating pres- sure, clean filter element.

If filter is used with a spa, soak element (see “Special Cleaning Instructions,” Page 9) at each regular clean- ing.

Filter elements are too heavy for safe lifting when wet and dirty. To avoid back injury, clean and drain elements as far as possible in operating position in filter tank. Have two people lift elements and lift with care. Follow cleaning procedure given below.

A. Cleaning in Place Procedure:

1.Follow steps one through six under “Disassembly”, Page 5.

2.With a garden hose, hose as much dirt as possible off of filter elements while they are still in place in- side the tank (See recommendations, below, right). Allow tank to drain completely. Make sure that waste water disposal complies with local codes and ordi- nances.

3.Lift out center element and hose it down thor- oughly. Allow to drain.

4.With large element still in tank, hose down both inner and outer pleats

5.Inspect large element. If it is still dirty, allow it to drain thoroughly, lift it out of tank and repeat wash- ing operation; then go to Step 6. If it is clean, got to Step 7.

Filter elements are heavy when wet and dirty. To avoid back injury, allow filter element to drain completely before removing from tank. Have two people lift element and lift with care.

6.Once it is clean, allow large element to drain thor- oughly, then reinstall in filter tank.

NOTICE: If this cleaning method does not remove stubborn deposits, use “Special Cleaning Instructions”, at right.

7.Reinstall center element

8.Follow steps one through eight under “Assembly”, Page 5.

B. Special Cleaning Instructions:

Use this procedure to clean scale or oils which are not removed by simply hosing down and scrubbing ele- ment. Be sure to dispose of spent chemicals according to all applicable codes and waste disposal ordinances. Use a soft stream nozzle to minimize flying water and spray.

Figure 3 - Hose down elements thoroughly.

Figure 4 - Clean inside as well as outside of elements.

Follow these recommendations for easier cleaning with a garden hose:

1.Prepare to get wet!

2.Use a soft flow nozzle which will reduce spray around filter.

3.Move around element while spraying to reach entire sur- face.

4.Repeat wash-down process for inside of element. Hold nozzle as close to inside of pleats as possible.

NOTICE: BE SURE all dirt and foreign material is washed away from INSIDE pleats of element.

5.Drain elements as much as possible before trying to lift them.
