Begin with Option 1 and continue with other options if necessary
2.
For the first
week or so, test
the water daily
for free chlorine
or bromine.
3.
After day one, adjust the dial
up by 1/2 increment if the reading
has dropped or down by 1/2 incre-
ment if the reading has risen.
Continue this process each day
until the reading stabilizes at your
desired level between 1.0 and 3.0
ppm.
4.
For
Models 940,
960 & 980
use the
handle end of
cap tool if the
dial is hard to
turn.
Increase the
number of
hours your
pump runs
per day.
If reading dropped below 1.0 ppm, shock pool.
Turn control dial to minimum when shocking
and NEVER ADD SHOCK IN OR NEAR THE
SKIMMER. Reset dial 1/2 setting higher than
before and continue monitoring daily until
desired chemical level is acheived.
Decrease the
number of hours
your pump runs
per day. Water
must circulate fully
once a day.
Turn dial to minimum or
Setting 0. When reading
drops to desired ppm, reset
dial 1 setting lower than the
starting dial setting and
continue monitoring daily.
When using slow dissolving trichlor, the Perform-Max should be operated based on its normal erosion design where
only the bottom layer of tablets are wetted. This provides better controllability and longer lasting sanitation per refill.
When using bromine, the Perform-Max should be operated as a soaking feeder as this chemical works best when
all tablets are wetted. Therefore bleeding the air on these units is recommended when using bromine.
7.
Replace knob.
8.
For proper initial setting
continue to next section: Setting
Control Dial.
6.
Replace cap by hand only.
DO NOT OVER TIGHTEN.
Do not use cap tool to tighten
cap. For removal only.
