CAUTION
Never use dry acid to adjust pH in arid geographic
areas with excessive evaporation and minimal dilution
of pool water with fresh water. A build up of by
products can damage the electrolytic cell.
Section 6. Operating Instructions
6.1
Control PanelTurning Power Pack On/
Off (Manually)
To turn the Jandy
TruClearXL
chlorine generating device
on or off press the on/off button.
A quick press will place the chlorinator into “standby”
state. While in “standby” mode a quick press will return to
“chlorinating” mode. If held down for 6 seconds it will
completely power down.
NOTE
Because the power pack is wired to the pump’s
power source, the power pack can only be turned on
when the pump is turned on.
6.2
Turning Power Pack On/Off (Using the
Pump’s External Timer)
If the power pack is wired to the pump’s external timer
and the power to the unit is on, the power pack will
automatically turn on and off when the pump turns on
and off (see Section 3.5). When the power pack is wired
as such, the only setting that must be set manually is the
chlorine output level (see Section 5.4).
6.3
Chlorine Output Level
When setting the chlorine output level, the factors to
consider are:
-
number of gallons in the pool
-
number of bathers (bather load)
-
amount of pollen and dust going in the water
-
number of hours the pump runs
-
whether you are using a single or variable speed pump
-
climate and water temperature
-
amount of rain water entering the pool.
A good starting point for pools at 57,000L (15K) gallons
and under should be 40%. Pools closer to the 95,000 L
114,000 L (25K to 30K gallons) should use 60% as a
starting point.
If you find that these levels do not provide the 1 - 3 PPM
chlorine residual that is desired, then raise the output
level higher to compensate.
If you find that output level is approaching 90% to 100%
and testing the pool water shows no or very low chlorine
residual, your pool may need to be manually shocked
due to a waste load that has built up in the pool water
that is overwhelming the chlorine you are supplying to
the pool. Another cause may be the lack of Cyanuric Acid
(CYA) at appropriate levels to protect the chlorine from
the UV rays of the sun.
NOTE
The unit only runs while your pump is running.
More pump runtime will result with more chlorine in
the water.
With all the variables mentioned above, it may take you a
couple weeks to find the right production rate for your pool.
To adjust the output level, follow these steps:
1.
Turn the power pack on by pressing the on /off
button.
2.
Press the up down buttons to reach the desired
output level. The minimum setting is 10%. The
output can be adjusted in increments of 5% up to
100%. This controls the amount of run time for the
cell.
6.4
BOOST/LOW Mode
The BOOST mode can be used to maximize chlorine
output for a short period of time. To activate BOOST
mode, press the up and down buttons simultaneously.
The boost will turn off after 24 hours. To turn off BOOST
mode manually, press the left button.
The LOW mode can be used to minimize chlorine output
while activated. To activate LOW mode, press the down
and right buttons simultaneously. The LOW mode will
stay on indefinitely. To turn off LOW mode, press the left
button
6.5
Polarity Reversal
The Jandy
TruClearXL
chlorine generating device is a
reversible polarity cell which means that the cell will
periodically switch its polarity to help prevent any build
up of calcium on the cell plates. This is sometimes
referred to as the automated cell cleaning feature.
During the transition between changing its polarity there
is a brief period when the cell will not produce any
chlorine. Once it has changed polarity, it will continue to
make chlorine.
The default reversal time is three hours. To change the
reversal time, press and hold the up and down arrows
simultaneously to enter the service mode. Press the right
arrow key once to select “Cyc=”. Use the up button to
cycle between three and five hour cycles. Press the left
button to exit.
NOTE
‘CLEANING’ will be displayed on the screen
during the ‘WAIT’ period. The output level indicator
will remain as set during the cleaning period.
IMPORTANT
Always test the chlorine levels of your
pool before each use. During heavy usage where
bather load is increased, chlorine levels may
deplete quickly and require more adjustments.
Monitor the chlorine closely, and take appropriate
measures in order to maintain the recommended 1
- 3 ppm free chlorine residual
.
