Overnight Operation
To program the
Hydrochlor®
to run the pump from a period of time that involves starting before
midnight and ending after midnight, it has to be divided in two periods.
For example: If it required the pump to start at 23:00 and finish at 07:00. Then the Electrochlor LCD
setting should be break into 2 program periods like this:
r1SPHSBN5JNFSTFUUP4UBSUBUBOE'JOJTIBU
r1SPHSBN5JNFSTFUUPTUBSUBUBOE'JOJTIBU
Note:
To Reset the Timer, and Timers setting to factory defaults, press Reset Key until the time
displayed is 0:00.
CHLORINE PRODUCTION LEVELS
The output of the chlorinator can be adjusted to reflect the different seasonal requirements in order
to maintain satisfactory chlorine sanitizer levels.
The amount of chlorine produced can be adjusted by pressing the
CHLORINE PRODUCTION
CONTROL
key. Press button to raise production. If production already set at maximum it will turn
UP[FSPBOEFBDIQSFTTXJMMSBJTFQSPEVDUJPOCZPOF-&%UJMM."9
If the pool water is over chlorinated, simply reduce the chlorine production set level.
CHLORINATOR OVERRIDE SWITCH
Normal operation is (O). To start override switch to (–) to initiate override function of stopping pump

simply turn the pump on and off.
Caution:
When the chlorinator override switch is activated the pump protection is disabled. Do not
leave the pump unattended during. Pump may run dry and may void the warranty.
PUMP PROTECTION
When
NO WATER FLOW
is detected, the Chlorinator is prevented from turning ON. If no water
flow is detected in the salt cell,
Hydrochlor®
automatically switches off the pump to prevent any
damage to the pump and pool equipment. The
NO WATER FLOW LED
Indicator will start blinking
on the panel to alert the pool owner, until the fault is rectified.
WATER CHEMISTRY
Salt Level
The Hydrochlor® chlorinators must operate between the salt level ranges listed below.
r.*/*.6.QQNr015*.6.QQN
r."9*.6.QQN
Testing kits are available from the local pool professional and should be used to accurately check
the salt levels in the pool water.
Note:
When the LED lights flash it is an indication of:
t-PXTBMUMFWFM
t-PXUFNQFSBUVSFPS
t$FMMQMBUFTXFBSJOH
If you don’t know what your salt level is or how to test it, consult your local pool care specialist.
Water Chemistry
It is important to maintain the correct water chemical balance in the swimming pool; this will help
protect the Electrochlor chlorinator unit and its cell.
Consult the local pool professional for the correct water balance according to the swimming pool
type.
The Electrochlor chlorinator will run correctly at the following chemistry levels

Hydrochlor to standby mode.
b. Unscrew the barrel unions from the salt cell and disconnect the cables
from the salt cell’s brass connectors.
c. Turn the salt cell housing upside down with both ports facing upwards.
d. Pour the Cell Wash cleaning solution into the housing to dissolve the calcium build-up from the
salt cell plates. There should be just enough solution to cover the salt cell plates.
e. Allow enough time for the solution to dissolve the calcium build-up from the salt cell plates.
Approximately 5 to 10 minutes.
f. Once the calcium build-up has been removed, pour out the Cell Wash solution into a bucket and
lightly rinse-off excess calcium and Cell Wash solution from the salt cell assembly, with fresh
water.
g. Reconnect the salt cell onto the filter system
h. Press the

Never use products that are not specifically manufactured to clean the Hydrochlor®’s salt
cell. Do not use raw acids such as Hydrochloric acid. This will damage the salt cell and
severely shortens its life and will void warranty. Please consult your local pool professional
for advice on salt cell cleaning products.
