SECTION 1
WATER FILTER START-UP
I I
1E. ADJUSTMENT FOR POTASSIUM PERMANGANATE USE
ii ii
The filter is factory set to use about 2 ounces of
potassium permanganate each recharge. That's how
much is needed to keep the mineral bed working the
way it should. However, if you recharge the filter more
often than needed (see the table on page 8) less
potassium permanganate is needed each time.
The valve (FIG. 3) has a tube that raises and lowers
into the bottle. It has 2 settings marked on it. The "A"
mark, or factory setting, is for 2 ounces of potassium
permanganate. The "B" setting is for 1 ounce.
To change the setting, loosen the adjustment nut.
Raise the tube until "B" lines up with the top of the nut,
then tighten the nut.
IMPORTANT:
For proper recharging of the mineral bed, use the
"A" setting. Use the "B" setting ONLY if the filter
is set to recharge more often than the table on
page 8 shews. Improper recharging will shorten
the useful life of the mineral bed.
