JED 103 INSTALLATION AND OPERATION MANUAL
DESCRIPTION
The JED 103 is a CD or "corona discharge" type ozone generator designed for water purification in residential or commercial
hot tubs and swim spas up to 800 gallons, and fountains, tanks and lap pools up to 2500 gallons. Different applications require
differing amounts of ozone based on variables such as temperature, contaminant level, intended water usage and other water
treatment methods that are employed. JED 103 is typically installed in conjunction with a venturi injector or dedicated air jet.
IMPORTANT SAFETY INSTRUCTIONS
When installing and using the JED 103 basic safety precautions should always be followed.
1. READ AND FOLLOW ALL INSTRUCTIONS
2. DO NOT use the JED 103 for any purpose other than water purification and only according to the instructions.
3. DO NOT directly breathe the ozone from the discharge tube.
4. DO NOT operate the unit before it has been permanently mounted.
5. DO NOT touch the ozonator when wet or with wet hands. Fatal electrical shock could result.
6. DANGER - To reduce the risk of injury, do not permit children to use this product unless they are closely supervised.
7. Connect to a grounded grounding type receptacle of a 20 ampere or less branch circuit.
8. Do not bury the electrical cord.
9. WARNING - To reduce the risk of electrical shock, replace damaged cord immediately.
10. If the unit is connected to a ground fault circuit interrupter (GFI): Before each use of your spa (hot tub) test the GFI. If the
interrupter fails to operate in this manner, there is a ground current flowing, indicating the possibility of electrical shock.
Disconnect the plug from the receptacle until the source of the breakdown has been identified and corrected.
11. SAVE THESE INSTRUCTIONS.

MOUNTING
Install the JED 103 under the skirt of a portable spa, indoors or in a rainproof enclosure. The JED 103 is not weatherproof and
must be installed in a dry location. Please contact JED Engineering if a rainproof enclosure is required.
ELECTRICAL CONNECTION
1. Turn off power to the spa before attempting to install. The JED 103 comes with the hardwired power cord specified in your
order, to fit your application. There are a variety of power plug configurations available. If you find that you have received the
wrong plug, please contact JED Engineering for a replacement.
2. The JED 103 is available in 120 VAC and 240 VAC models. Please verify both the voltage of the ozonator and power
supply prior to installation.
3. The electrical installation must be made in accordance with local regulations. Overcurrent protection must be provided by
connection to a branch circuit rated at 20 Amperes or less. If hard wiring the unit, the wire color code is as follows: GREEN IS
GROUND, BLACK IS HOT AND WHITE IS NEUTRAL (For 240V both black and white are hot-120V each).
