JED 203 INSTALLATION AND SERVICE PART NUMBERS
The JED 203 is designed for water purification in residential and commercia! hot tubs, small pools, fountains, cisterns and
water tanks up to 5000 gallons. The JED 203 is supplied in a plastic rainproof enclosure that can be wall mounted outdoors.
The JED 203 has its own air compressor which can pump ozone into a pool, tub or tank up to 24 hours a day independently
of water circulation. The JED 203 is typically installed in conjunction with an over the side kit or tnru-hull fitting.
IMPORTANT SAFETY INSTRUCTIONS
When installing and using the JED 203 basic safety precautions should always be followed.
OZONE INFORMATION AND HELPFUL HINTS
1. READ AND FOLLOW ALL INSTRUCTIONS
2. DO NOT use the JED 203 for any purpose other than water purification and only according to the instructions.
3. DO NOT direclly breathe the ozone from the discharge tube.
4. DO NOT operate the JED 203 before it has been penmanenlly mounted.
5. DO NOT touch the JED 203 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.
In the event thai the JED 203 fails to operate. please contact the factory for repair or replacement. The JED 203 is covered by a
one-year full warranty. It is also designed to be field serviceable.
1. It costs less than one cenl per hour to operate the JED 203.
2. The water should be changed a minimum of twice per year. The Canadian Standards Association, CSA, recommends changing
the water once per month.
3. The ozone-laden air kills algae and bacteria upon contact as the bubbles rise in the water. The ozone does not readily combine
with the water and consequently the surface area of the bubble is the point of contact between ozone and the contaminants.
4. The ozone is produced in the JED 203 when air passes through a high voltage electrical discharge or "corona."
5. The ozone residual in the water is so slight that inexpensive test kids are not accurate enough to readily test for the existence of
ozone,
6. Verification that the unit is working is demonstrated by the smell of ozone and by bubbles coming to the water surface from the
ozone discharge tube.
T, The JED 203 is more effective when a spa cover is utilized.
8. In the event of a power outage or other event that causes the JED 203 to be off for a duration of time. it is necessary to "shock"
the water with chlorine or bromine. Use 114cup of chlorine for every 100 gallons and do not use the spa for several days.
9. Even though the unit is performing effectively, there can still be discoloration at the water line caused by human body excretion.
To remove, use any good chemical preparation for this purpose such as monosodium per sulfate or liquid chlorine.
10. CieaninD the filter more often i::. frequently required '.'iith ozone purification.

close proximity to where the ozone will be introduced to the water.
March 1. 2001 ELECTRICAL CONNECTION
Engineering, Inc.
1. Turn off power to the spa before attempting to install. The JED 203 should be wired to an appropriate 120 VAC
source which will be energized 24 hours a day.
2. The electrical installation must be made in accordance with local regulations. The standard NEMA line cord simply
plugs into a grounded 120 VAC wall outlet. Other plug configurations are also available. (See service parts list.)
Overcurrent protection must be provided by connection to a branch circuit rated at 20 amperes or less. If you are
hard wiring the unit, follow the spa manufacturers installation instructions. The color codes of the wires from the
ozonator to the spa are as follows: GREEN IS GROUND. BLACK IS HOT AND WHITE IS NEUTRAL
3. An IntenmatiC® heavy duty multi-setting timer is recommended for setting JED 203 operation times.

MAINTENANCE AND DAILY USE
Water Tank Installation with "over the side kit"
1. Use of an ozonator requires water filtration 10 remove dead bacteria and algae particles. In order to derive the maximum
benefits from the JED 203 ozone generator, the filtration pump should be run a minimum of 60 minutes per day.
2. Clean the filter monthly and check more often if it seems necessary.
3. If during use of spa it is relt undesirable to have the ozone entering the water, turn the unit off.
4. The ozone generating CD subassembly has a defined life and degrades in its ability to generale ozone over time.
5. To replace the CD subassembly, see "CD Subassembly" section of these instructions.
6. A residual ring ("bathtub ring") is experienced in all spas and is best removed with a product specifically designed for this
purpose. The best non-chtorine chemical for this process is monosodium persulfate.
7. A!though ozone is a more powerful killer of bacteria and algae than any chemical, such as chlorine, there is one advantage to
chemical purification. The killing effect of ozone in the spa is generally limited to contact of the outside sphere of the bubbles
with the water, and the killing effect of Ihe chemicals is affected by mixing into the water. Because of this difference when
ozone is employed, surfaces (such as spa walls and bottom) are not disinfected, for only the water is disinfected. During spa
use bacteria may cling to the surfaces which result in a slippery feel. This bacteria can be eliminated by using a towel or rag
and wiping down these surfaces followed by using the filtration pump for approximately one hour. A shock of any liquid or
powdered dissolvable disinfectant will also elimlnate the Slippery surface. The human body will usually excrete about 1/4 cup of
perspiration during spa use, so it is easy to understand how bacteria are introduced info the water.
OZONE HOSE TO SPA
1. Connect the long clear hose 10the clear check valve, which is protruding from the bottom of the JED 203.
2. Drill a small hole (3/8") as close to the top of the skirt as possible.
3. Bring the clear hose from the ozonator up through the hole and attach it to the optional weighted airstone. Drop the
weighted stone into the spa so it rests on the bottom. A Hartford loop above the water line will help prevent water from
back fiowing into the ozonator in the event of a check valve failure.
4. Ozone can also be introduced from the JEO 203 via an ozone resistant thru-hull fitting or a hose-bib adapter connected
to the drain valve.

SHOCKING WITH LIQUID CHLORINE
In the event that the spa water has become cloudy, it is necessary to shock the water with chlorine or bromine. Cloudy water is
caused by excessive use of the spa, which introduces contaminants, particularly bacteria. A guide for shocking for each 100
gallons of water is as follows: Normal shock: 1/4 cup, Heavy shock, 1 cup. The JED 203 can be used in combination with
bromine, chlorine, ionization or 8aquacil.
Q!j
-'
The recommended pH for spas is 5.5 or higher. Refer to your spa manufacturer's owner manual for further details. Ozone
purification is very user friendly and does not require a specific pH level to be effective. A lower pH than required for chlorine is
healthier for the skin and hair.
CD SUBASSEMBLY REPLACEMENT
Weighted Dispersion stone
The anticipated life expectancy of the CD subassembly is approximately 1 year, depending on the ozonator run time. After 1
year, we recommend replacing the CD subassembly. When replacing it, specify JED Engineering part number 80-39-70000.
~INSTRUCTIONS FOR REPLACEMENT OF CD SUBASSEMBLY
INITIAL WATER PURIFICATION
1. Turn off power. Let unit cool.
2. Remove two holding nuts on CO subassembly.
3. Snip both connection wires between the CD subassembly and the transfonmer.
4. Wire the new CD subassembly to the transfonmer with the wire nuts supplied.
5. Reattach the ozone resistant tubing and tighten back down with the two holding nuts. Do not over tighten.
1. Shock the spa water with liquid chlorine using 1/4 cup of chlorine for each 100 gallons of spa capacity. Other oxidizing agenls,
such as bromine, hydrogen peroxide, or monosodium persulfate can be substituted and their instructions should be followed.
2. Because meta! compounds can be precipitated out of solution with the uce of ozone, it is recommended to use a commercially
available metal remover such as "Protect All" or "Metal Magnet."
3. Allow filtration pump to run continuously for 2 days without turning on the JED 203 ozone generator.
4. After following step 3, set the filtration pump timer to run according to the spa manufacturer's recommendations, or a minimum
of 60 minutes per day.
5, Activate the JED 203 by plugging it in and adjusting the timer on the spa to run at the appropriate times (see customer
adjustments section.)
6. Clean the spa filter after the first week of operation and again in one week.

*IMPORTANT*
Please Review Carefully Before Installing Your New
Corona Discharge Ozone Generator.
Be sure to:
1. Mount unit under the spa skirt, as high on the wall as possible.
2. Unit must be mounted vertically.
3. Please verify that the JED CD Ozonator (120V or 240V) matches
your power source voltage, V.
4. Install second check valve between the venturi injector and ozone
generator.
We recommend that you:
1. Mount the venturi injector near the top of the spa skirt with the
tubing sloping downward from the injector outlet.
2. Incorporate two Hartford loops above the water line if possible.
Please Note:
For all models, excluding the JED 203 & 603, suction is
required to get ozone into the water. The ozone generators
depend on vacuum from a venturi injector. They produce no
airflow themselves. The ozonator must have air drawn
through it. The ozonator should only have power when suction
is available or it may fail prematurely. Check suction
periodically. Proper suction will increase the performance and
longevity of your ozonator.
