Section 1. Important Safety Instructions
READ AND FOLLOW ALL INSTRUCTIONS
All electrical work must be performed by a licensed electrician and conform to all national, state, and local
codes. 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.
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
To Reduce the Risk of Injury -
a) The water in a spa should never exceed 40°C. Water temperatures should remain between 38°C and 40°C.
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. 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 drowsiness while other medication may affect heart rate, blood pressure, and circulation.
WARNING
Risk of electric shock -
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.
