SECTION IV.
INITIAL START UP AND RESTART INSTRUCTIONS.
1. Be sure all connections have been made and are secure.
2. Make sure the hair and lint pot of the pump is filled with water. (FAILURE TO FILL THE
HAIR AND LINT POT WITH WATER WILL RESULT IN DAMAGE TO THE PUMP
AND PUMP SEAL).
3. OPEN THE HIGH FLOW TM MANUAL AIR RELIEF VALVE UNTIL IT SNAPS INTO
THE FULL OPEN POSITION (THIS ONLY REQUIRES A ¼ TURN COUNTER-
CLOCKWISE).
4. STAND CLEAR OF THE FILTER. Start pump allowing the filter tank to fill with water.
Close the High Flow TM manual air relief valve after a steady stream of water appears.
5. COATING THE FILTER ELEMENTS WITH DIATOMACEOUS EARTH. With the
pump on, introduce the recommended amount of D.E. through the skimmer (see chart
below), this will pre-coat the element grids. A 1 lb. coffee can is equal to ½ lb of D.E.; see
Chart 1.
DIATOMACEOUS EARTH, CHART 1
Model Rated No. of 1 lbs. Weight of
No. GPM Coffee Cans Diatomite
56344xxx 44 3 1.5 lbs
56366xxx 66 4 2 lbs
CAUTION
Do not operate filter for more than two minutes without a pre-coat of D.E. on the grids.
6. Your filter has now started its filter cycle. You should check that the water is returning to
the pool and take note of the operating pressure.
My original starting pressure is ________PSI with the filter clean.
7. Check the system for water leaks. If a leak is found, shut off pump before correcting the
leak.
8. As the filter removes dirt and impurities from the pool water, the accumulation will cause
the filter pressure to rise and the flow to diminish. When the pressure gauge reading is 8 to
10 PSI higher than the clean filter reading noted above, it is time to clean the filter’s
element grids, see SECTION V. CLEANING THE FILTER.
