Important Safety Instructions
READ AND FOLLOW ALL INSTRUCTIONS
All electrical work must be performed in accordance with AS/NZ 3000.
When installing and using this electrical equipment, basic safety precautions
should always be followed, including the following:
WARNING
Prolonged immersion in hot water may induce hyperthermia. Hyperthermia
occurs when the internal temperature of the body reaches a level several
degrees above the normal body temperature of 37°C. The symptoms of
hyperthermia include dizziness, fainting, drowsiness, lethargy, and an increase
in the internal temperature of the body. The effects of hyperthermia include:
1) unawareness of impending danger; 2) failure to perceive heat; 3) failure to
recognize the need to exit spa; 4) physical inability to exit spa; 5) fetal damage
in pregnant women; 6) unconsciousness resulting in a danger of drowning.
The use of alcohol, drugs, or medication can greatly increase the risk of fatal
hyperthermia.
DANGER
To reduce the risk of severe injury or death, do not remove the suction fittings
of your spa or hot tub. Never operate a spa or hot tub if the suction fittings are
broken or missing. Never replace a suction fitting with one rated less than the
flow rate marked on the equipment assembly.
WARNING
Risk of electric shock which could result in severe injury or death - Install
the controller at least 3.5 metres from the inside wall of the pool and/or hot tub
using non-metallic plumbing.
Children should not use spas or hot tubs without adult supervision.
Do not use spas or hot tubs unless all suction guards are installed to prevent
body and hair entrapment.
People using medications and/or having an adverse medical history should
consult a physician before using a spa or hot tub.
WARNING
To avoid injury ensure that you use this control system to control only
packaged pool/spa heaters which have built-in operating and high limit controls
to limit water temperature for pool/spa applications. This device should not be
relied upon as a safety limit control.

3
WARNING
To Reduce the Risk of Injury -
a) The water in a spa should never exceed 40°C. Water temperatures
between 38°C and 40°C are considered safe for a healthy adult. Lower water
temperatures are recommended for young children and when spa use exceeds
10 minutes.
b) Since excessive water temperatures have a high potential for causing fetal
damage during the early months of pregnancy, pregnant or possibly pregnant
women should limit spa water temperatures to 38°C.
c) Before entering a spa or hot tub, the user should measure the water
temperature with an accurate thermometer since the tolerance of water
temperature-regulating devices varies.
d) The use of alcohol, drugs, or medication before or during spa or hot tub use
may lead to unconsciousness with the possibility of drowning.
e) Obese persons and persons with a history of heart disease, low or high
blood pressure, circulatory system problems, or diabetes should consult a
physician before using a spa.
f) Persons using medication should consult a physician before using a spa or
hot tub since some medication may induce drowsines while other medication
may affect heart rate, blood pressure, and circulation.
People with infectious diseases should not use a spa or hot tub.
To avoid injury, exercise care when entering or exiting the spa or hot tub.
Do not use drugs or alcohol before or during the use of a spa or hot tub to
avoid unconsciousness and possible drowning.
Pregnant or possibly pregnant women should consult a physician before using
a spa or hot tub.
Water temperature in excess of 38°C may be injurious to your health.
Before entering a spa or hot tub, measure the water temperature with an
accurate thermometer.
Do not use a spa or hot tub immediately following strenuous exercise.
Prolonged immersion in a spa or hot tub may be injurious to your health.
Do not permit any electric appliance (such as a light, telephone, radio, or
television) within 1.52m of a spa or hot tub.
The use of alcohol, drugs or medication can greatly increase the risk of fatal
hypothermia in hot tubs and spas.

TURNING CHLORINE GENERATION ON
The chlorine generation of the TRi-XO can be controlled in a number of ways:
1. Manually set to an output level, with the operating times determined by an
external timer.
2. Using the in-built timers on the TRi-XO unit (refer to ‘The Timers’)
3. Using a connection to an external controller (refer to ‘Connecting to a controller’).
To turn the chlorine generation on manually, press the ON/OFF button. The output
level can be set as described in ‘Setting the Chlorine Output.’
NOTE: For safety reasons, the TRi-XO chlorine generator will continually dose
chlorine for a maximum of 30 hours if left running with no ‘OFF’ time – unless
connected to en external controller. After this time the TRi-XO will switch to ‘OFF’.
THE TIMERS
• The Zodiac TRi-XO chlorine generator comes with two inbuilt timers that switch
the ltration and chlorination system on and off as required.
• During swimming season, consider running the system for around 8 hours a
day. This can be increased to 10 hours during periods of very hot weather.
• In winter, it may only be necessary to run your pool’s ltration system for 4
hours a day. These shorter periods of activity will lengthen the life of the unit’s
electrode.
• For best year round results, set the unit to operate during the cooler hours of
the early morning, evening or when swimmers are using the pool.
PROGRAMMING THE TIMERS
• To activate the timer, you will need to enter both an ON and OFF time.
If no OFF time is entered, the chlorine generator will switch off at the default
time of 12:00am (0:00).
