3.3 TIMER RECOMMENDATIONS:
Hurlcon recommend that you use two timers, one for the morning and one for the evening and typically for periods
of 2-5 hours for each. Your E Series CSD Chlorinator is most effective if running in the early morning or evening
when it is cooler (strong sunlight consumes more chlorine). As a default, the control is set to come on at 08:00
hours and 16:00 hours both for periods of 4 hours.

OPERATING FUNCTIONS ACCESSED THROUGH MAINTENANCE PROGRAM
To backwash your filter press BWASH and then the up or down arrows to select the backwash time. You can
press ABORT at any time to finish the back wash. To rinse the filter, you can select BWASH again and then
select the time. Using this feature will ensure your sand filter is backwashed for the correct time. Note: Ensure
pump is off when changing the position of the backwash valve on your filter. As a guide, sand filters should be
backwashed for 2 to 3 minutes, and then rinsed for 1 minute.

Then press NEXT to display the following Screen. Selecting dose will allow you to override the time clock and
allow the following:
i. Sanitise until the first timer tomorrow morning. This allows for additional circulation of the swimming pool
water after treatment or cleaning
ii. Manually prime Acid Pump. This allows for the clear PVC tube to be filled with Acid on initial start up or
after changing or refilling the Acid Container. The priming period is for 300 seconds but can be stopped at
any time. Should the tube not be completely filled with Acid after 300 seconds repeat the process.
iii. Manually Dose Acid. Selecting this function allows you to manually dose acid for a predetermined time.
Should your pool professional recommend the addition of Acid to your pool, select this function and press
the up (or down) arrow to select the quantity of acid in litres you wish to dose. Press ACCEPT. The
controller will then ask you what mode you wish the unit to revert to at the completion of Acid dosing,
“AUTO”, “ON” or “OFF”. In normal circumstances you will select “AUTO” which puts the unit back into
time clock operation.
iv. INSTALL allows the unit to be set up for your pool or spa. This should only be selected in the initial start
up of your Chlorinator. Select INSTALL and the following will occur:
a. SET POOL WATER VOLUME, select YES and then use up or down arrows to change the volume of your
