SYSTEM INSPECTION

General:

Wash the outside of the filter with a mild detergent and water. Rinse off with a
hose.

NOTICE: 

DO NOT use solvents to clean the filter; solvents may damage plas-

tic components in the system.

NOTICE: 

Open the air bleed valve and bleed all air from the filter each time

the pump is stopped and restarted.

Weekly Inspection:

1. Remove debris from the pool skimmer basket.
2. Stop the pump; open the air release valve to release all pressure. 
3. Remove the trap cover and basket; remove debris.
4. Check the pump for leaks. If found, see the pump owner's manual.
5. Replace the trap basket and the cover. Tighten the cover securely hand

tight. DO NOT use a lid wrench to tighten it.

6. Start the pump. When the filter air release valve runs a solid stream of

water, close the valve.

7. When the system has returned to normal operation, check the filter pres-

sure. If the filter pressure is 10 PSI (69kPa) or more higher than the initial
startup pressure, the filter needs cleaning. See “Module Cleaning
Procedure”, Page 8.

WINTERIZING

Explosion hazard. Purging the system with compressed air can

cause components to explode, with risk of severe injury or death to anyone
nearby.

Use only a low pressure (below 5 PSI), high volume blower when air

purging the pump, filter, or piping.

NOTICE: 

Protect the filter from freezing. Allowing the filter to freeze will dam-

age it and will void the warranty.
1. Clean the filter according to instructions  (Page 8) before winterizing. 
2. Stop the pump.
3. Open the air release valve; open all the system valves.
4. Remove the drain plugs from the trap, pump, and filter.
5. Drain the system piping.

A. Gravity drain system as far as possible.
B. Protect areas which retain water with non-toxic propylene glycol 

antifreeze (“RV antifreeze”).

6. Loosen the union nuts (if used) to drain all water from the filter interior.

Leave these nuts loose until the system is restarted.

7. Disassemble the filter (follow instructions under “Filter Disassembly”, Pages

6 and 7). Remove the filter module and store it in a warm, dry area.

8. If the filter is equipped with an optional internal spring check valve (in the

tank outlet), manually open the check valve to allow any water trapped in
the tank to drain.

9. Cover the filter with plastic or tarpaulin to prevent water entrance and

freezing.

NOTICE

The filter outlet piping will not empty
through  the filter drain. Make sure that
the outlet piping has a separate drain for
winterizing.
