KEYPADS 9 and 0:
“INCREASE AND DECREASE CHLORINE SET LEVELS”
Keypads 9 and 0 are used to set the level of Chlorine required in the pool water. The
keypads raise or lower the required level and the Chemigem will then acquire and hold the
set level.
If the Chlorine level required is to be lowered, keypad 9 will lower the set level. It may take
some days or even weeks before the Chlorine level drops to the required setting.
However, if the Chlorine level is to be raised, press keypad 0. The unit will feed Chlorine
every 3 minutes until the set level is reached.
To manually turn off the Chlorine and to turn it on again, refer to page 23
KEYPAD “ORP”: “CHLORINE MANUAL FEED”
If, as a result of a pool water test, it is determined that the Chlorine is not within acceptable
levels, the Chemigem can perform a manual dosing operation to bring the level up rapidly.
The unit is equipped with the facility to override its normal operation and to dose Chlorine
manually. Keypad “ORP” performs this function.
Refer also to keypad “pH” that manually feeds pool Acid (pH)
Normally it will only be necessary to manually dose either Chlorine or pH, however if for
any reason keypads “ORP” and “pH” are both pressed at once, only the pH will operate.
As soon as the manual-feed keypad is pressed the main screen will appear blank for 2
seconds after which it will display which feed is taking place.
Feeding will continue for about 20 seconds, while the keypad is pressed.
When the display panel returns to normal the dosing stops.
Press again to repeat as many times as required.
After manually dosing with Chlorine, monitor the setting for several hours afterwards to
make sure that the recommended levels have been restored.
KEYPAD “pH”: “POOL ACID MANUAL FEED”
If, as a result of a pool water test, it is determined that the Pool Acid (pH) is not within
acceptable levels, the Chemigem can perform a manual dosing operation to
lower the level
rapidly.
The unit is equipped with the facility to override its normal operation and to dose pool Acid
manually.
Refer also to keypad “ORP” that manually feeds Chlorine.
Normally it will only be necessary to manually dose either Chlorine or pool Acid, however if
for any reason keypads “ORP” and “pH” are both pressed at once, only the pool Acid will
operate.
