1. Introduction1. Introduction
INTRODUCTION
Your new Spa Sanitation System produces a pure form of chlorine by electrolysis of salt
(NaCl) in order to sanitize your spa water. Aer the salt is converted to chlorine and the
bacteria are killed, the chlorine converts back to salt in a continuous process. The salt
concentration used is very low (less than that in a human tear). Chlorine output can
be easily adjusted by the timer on the control panel. The chlorine level in your spa can
be checked by using a standard chlorine test kit. One unit can treat up to 2,200L (600
gallons) of spa water (or up to 5700L - 1500 gallons - for Swim Spa water).
WARNING: RISK OF ELECTRIC SHOCK.
Connect only to a grounding type receptacle
protected by a ground-fault-circuit-interrupter (GFCI).
Contact a qualified electrician if you cannot verify
that the receptacle is protected by a GFCI.
WARNING: To reduce the risk of electric
shock do not use extension cords to connect unit
to electric supply; if necessary, contact a qualified
electrician to provide a properly located outlet.
WARNING: Make sure the setting on the
control panel is set to zero when cleaning/servicing
the cell assembly.
This appliance is not intended for use by persons
(including children) with reduced physical, sensory
or mental capabilities, or lack of experience and
knowledge. Unless given proper supervision or
instruction concerning use of the appliance by a
person responsible for their safety.
Children should be supervised to ensure that they
do not play with the appliance. If the supply cord is
damaged, it must be replaced by the manufacturer,
its service agent or similarly qualified persons in
order to avoid a hazard.

WARNING: To reduce risk of injury, do not permit children to operate the
device.
WARNING: Heavy spa usage and higher temperatures may require higher
chlorine output to maintain proper free chlorine residuals.
If additional chlorine is required due to heavy bather loads, use granulated chlorine to
maintain an appropriate chlorine residual amount in the water.
DO NOT add spa chemicals directly to the skimmer. This may damage the cell.
Maintaining high salt and chlorine levels above recommended range can contribute to
corrosion of spa equipment. Check the expiry date of the test kit as test results may be
inaccurate if used aer that date.
The life expectancy of the electrode is 7,000 hours under normal use conditions.
When replacing the electrode, only use replacement electrodes having a label that
clearly states that it is a replacement electrode for the chlorine generating device.
For proper sanitation, spas should be completely drained periodically. The number of
days between COMPLETE SPA DRAINAGE is equal to the volume of spa water in liters,
divided by 10 times the maximum number of daily spa users. Refill spa with water and
repeat DIRECTIONS FOR USE of the device.
Health and Hyperthermia warnings for spa devices:
People with a medical condition should consult a physician before entering spa water.
Maximum spa water usage temperature is 40°C / 104°F. Bathing in spa water at 40°C /
104°F should not exceed 15 minutes.

2. Installation and Operation2. Installation and Operation
Operation of the Unit
I. Turn on the power to the spa equipment
II. Turn on main spa pump
III. Add required type and amount of salt to spa. Spread over
the surface and allow salt to dissolve for at least 1 hour
(Add the required free chlorine residual before startup to have
balanced water.)
NOTE: The spa chemistry must be balanced before installing
the system to the spa. (See page 12.)
During startup, add chlorine between 2-4 ppm as base
amount.
Be sure to test the chlorine level for the next few days and
properly adjust the chlorine output by adjusting the “Hours
Per Day” on the “Topside Control Panel”.
DO NOT EXCEED RECOMMENDED CHLORINE LEVELS!
Confirm the required adjustment and allow the spa to react to this change for a
minimum of 2 days.
Aer 2 days, retest the spa water and make any further adjustments as required until
the unit maintains an adequate Free Available Chlorine residual.
NOTE: The system works based on a natural convection of water, not a forced
convection as with an in-line systems. This operation is independent of the main
circulation pump. The cell must be submerged underwater for proper operation.
As the cell is energized to generate chlorine, bubbles will appear and it is normal.
If the cell is removed from the spa water, chlorine generation will automatically
stopped.

Control Panel Function
1. When the spa power is turned on:
All three LED lights and the display will be ON for
approximately 3 seconds while the unit self-tests.
2. Normal Operation:
If your salt level is within proper range 2000-2500
ppm, the Green light LED will display solid GREEN
and the display will show the operation hours
per day. This indicates power is being delivered
from the power supply unit to the cell and is
producing sanitizer. Your spa is being sanitized by
Hypochlorous Acid (chlorine).
While sanitizer is being produced, bubbles can
be seen coming from the cell
3. Abnormal Conditions:
The LED lights will flash rapidly and/or the display
will also flash to indicate a problem or failure. For
further explanation of the abnormal conditions,
please refer to the Troubleshooting Guide.
4. Chlorine Output Control:
The Chlorine output is controlled by adjusting
the Timer of the power supply. The Timer
determines the amount of hours per day the unit
is in operation in order to maintain the chlorine
residuals as needed.
The output is only regulated by the chlorine timer.
It operates independently from your filter pump
run time.
NOTE: Any interruption of electrical power will cause the current memory cycle to
reset when power is restored.
CHLORINE ADJUSTMENT
Aer everything is set up, the display will show you a default screen with the current
hours of operation per day. You may change this setting anytime by holding down
the button for 3 seconds straight. (See figure.) The display will flash, indicating
it is now ready for time-setting changes. To determine the proper chlorine timer setting
for your spa, measure the free chlorine level every day. Adjust the time accordingly
to achieve 2.0-4.0 PPM of Free Chlorine. It is advised to check the chlorine level daily
to make sure the spa is properly sanitized. Weather, bather load, and sunlight have a
major influence on the chlorine demand of the spa water.
NOTE: If the spa has reached an undesirable amount of chlorine, it is recommended
to lower the amount of hours per day to zero. Check chlorine levels each day until
the desired level is reached. Adjust the settings to maintain the chlorine level in
within the desired limit.
CONTROL PANEL FUNCTION:
1. When the spa power is turned on:
All three LED lights and the display will be ON for approximately 3 seconds while the
unit self-tests.
2. Normal Operation:
If your salt generator unit is operating properly, the Green LED light will display solid GREEN
and the display will show the operation hours per day. This indicates that power is being
delivered from the power supply unit to the cell and is producing sanitizer and your spa is
being sanitized by Hypochlorous Acid (chlorine). NOTE: While sanitizer is being produced,
bubbles can be seen coming from the cell!
3.Abnormal Conditions:
The LED lights will flash rapidly and/or the display will also flash to indicate a problem or
failure. For further explanation of the abnormal conditions, please refer to the
Troubleshooting Guide.
4. Chlorine Output Control
The chlorine output is controlled by the adjustment of the Timer of the power supply. The
Timer regulates the hours per day of the amount of " ON" time the system requires to maintain
the chlorine residuals as required.
The output is only regulated according to the chlorine Timer. It operates independently from
your filter pump run time.
NOTE: Any interruption of power will cause the current memory cycle to reset itself when
power is restored.
CHLORINE ADJUSTMENT
After everything is set up,the display will show you a default screen with the current hours of
operation per day. You may change this setting anytime by holding down the for 3 seconds
straight. (See Figure.) The display will flash indicating it is now ready for time setting changes.
In order to determine the proper chlorine timer setting for your spa, measure the free chlorine
level every day. Adjust the timer accordingly to achieve 2.0-4.0 PPM of Free Chlorine. It is
advised to check the chlorine level at least daily to make sure the spa is properly sanitized.
Weather, bather load, and sunlight have a major influence on the chlorine demand of the spa
water.
Note: If the spa has reached an undesirable amount of chlorine, it is recommended to unplug
the generator’s unit power. Check chlorine levels each day until
the
desired level is achieved.
Plug the power cord back once the chlorine level is within the desired limit.

3. Salt Requirement3. Salt Requirement
The best salt is food-quality granulated salt, 99.9% pure salt or solar salt. These types
of salt should be purchased from Cal Spas and are designed for use with chlorine
generators.
Do not use rock salt, iodized salt or salt with anti-caking additives. Do not use salt with
more than 1% yellow prussiate of soda.
The optimum salt level is between 2000-2500 ppm. Use the chart below to determine
the amount of salt for your spa. The column on the le is the amount of water in your
spa.
The column on the top is the current salt level measured in your spa. Always check
your salt level before adding salt to the spa especially if it is your first time.
Prior use of granulated chlorine could have caused in increase in salt levels. Salt should
not be removed from the spa unless the salinity exceeds 4000 ppm or the salinity of the
water is undesirable. The only way to remove salt is by draining the water and adding
fresh water.
NOTE: Turn unit o before adding sodium chloride and other chemicals, and wait
until complete dissolution before turning it on.

Removing and inspecting the cell:
Note: The cell should be inspected every 3 months.
Step 1. Adjust the chlorine
level to zero when
cleaning or servicing the
cell assembly.
Step 2. Inspect the cell for
scaling (white) deposits.
Step 3. If scaling exists,
the cell should be
cleaned.
The Cell is Attached to a Lanyard
Carefully remove grommet. Grommet has a slice to allow it to
slip o and reattach to the cord
Pull out about a foot of lanyard until the
connector appears
Twist and detach connector
to free cell for cleaning or
replacement.
(DO NOT LET THE SPA END OF THE CORD SLIP BACK INTO THE SPA’S HOLE!)

Cleaning the cell:
Step 1.Step 1. Fill the cup with the white vinegar.
Once the setting on the control panel is set to zero, the cell can be cleaned. Scale
build up will look similar to the image on the le. You will need a cup large enough to
submerge the entire cell, white vinegar (such as the one shown on the right image) to
submerge the cell, and an area where fresh water is available to rinse the cell.
Step 2.Step 2. Submerge cell into the container and ensure it is completely covered by
vinegar.
