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 10 the 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.
