INTRODUCTION
Saltron® MINI Spa Sanitation System produces a pure form of chlorine by electrolysis of salt (NaCl) in order to sanitize your spa water. After the salt is converted to
chlorine and the bacteria are killed, the chlorine converts back to salt and this process is ongoing. The salt concentration used is very low (less then that in a human
tear). Chlorine output can be easily adjusted by the timer on the power supply unit. The chlorine level in your spa can be checked by using a standard chlorine test
kit. One Saltron™ MINI unit can treat up to 600 gallons (2,200L) of spa water (or up to 2000 gallons Swim Spa water).
IMPORTANT SAFETY INSTRUCTIONS

automatically clean the cell plates, maximizing
the cell's ability to manufacture chlorine.
INSTALLATION AND OPERATION
SpaDepot.com
Installation of the Power Supply Unit:
The power supply can be mounted to a wall next to the spa or directly on the spa wall. The
wall needs to have easy access to a GFCI socket. In addition, install the Power Supply Unit
to a wall that ensures the least amount of direct exposure to rain, garden sprinkler water,
direct sunlight. When installing the power supply to the spa wall, please use the stainless
steel screws provided, fasten the Power Supply Unit to the top of the spa skirt, just below the
acrylic lip. Before tightening the screw, adjust the height of the Power Supply Unit to make
sure that the waterproof connector is outside of the spa water. (See Fig. 1)
Installation of the Cell Holder
Use the adhesive tape provided to anchor the CELL HOLDER to the spa skirt. Another
option is to directly attach it to the side of the Power Supply. (See Fig.2a-2c)
NOTE: The Saltron™ MINI over the wall cell should be removed whenever the spa is in
use. After installing the CELL HOLDER, simply hang the cell outside the spa inside the
CELL HOLDER during spa use.

Operation of the Saltron™ MINI
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 20 minutes.
IV. Place the cell in the spa (anywhere below the waterline, preferably one foot under).
V. Plug the Power Supply into an 110VAC/220 VAC GFCI protected outlet.
I
NOTE: 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 power supply front panel.
DO NOT EXCEED RECOMMENDED CHLORINE LEVELS!
Make the required adjustment and allow the spa to react to this change for a minimum of 2 days.
After 2 days, retest the spa water and make any further adjustments as required, until the Saltron™ MINI unit maintains an
adequate Free Available Chlorine residual.

NOTE: The Saltron™ MINI system works based on a natural convection of water, not a forced convection as in 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 is normal. If the cell is
removed from spa water, chlorine generation is automatically stopped.

INSTALLATION AND OPERATION
SpaDepot.com
POWER SUPPLY FUNCTION:
1. When the Power Supply is first plugged in:
All three LED lights and the display will be ON for approximately 3 seconds while the Saltron™
MINI unit self-tests.
2. Normal Operation:
If your Saltron™ MINI 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 Saltron™ MINI 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.

After everything is setup, 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 Fig.3)
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 couple of days during
the first few weeks. Adjust the timer accordingly to achieve 3.0-4.0 PPM of Free Chlorine. It is advised
to check the chlorine level at least once a week 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 Saltron™ MINI unit power supply from the GFCI socket. Check chlorine levels each day
until the desired level is achieved. Plug the power supply back into the GFCI socket once the
chlorine level is within the desired limit.

SALT REQUIREMENT
SpaDepot.com
The best salt is a food-quality granulated salt, a 99.9% pure salt or solar salt. These types of salt should be purchased from a pool store 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 left is the amount of water
in your pool. The column on the top is the current salt level measured in your pool. Always check your salt level before adding salt to the pool even if this is your first
time.
Prior use of liquid chlorine and tablets could have caused an increase in salt levels. Salt should not be removed from the spa water 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 Saltron™ MINI unit off before adding sodium chloride and other chemicals, and wait until complete dissolution before turning it on.

STABILIZER (CYANURIC ACID) LEVELS
Cyanuric Acid/Stabilizer/Conditioner (Required
with uncovered outdoor spas only)
Cyanuric acid, CYA, (also known as stabilizer or
conditioner) prevents rapid breakdown of
chlorine by direct sunlight. Maintain CYA
concentrations between 50-80 ppm by diluting
with fresh water.
Regulations may exist regarding use of
Cyanuric acid in spas; please consult with your
spa professional.
Use the following chart to determine the amount
of Cyanuric acid needed. Test water with a test
kit that includes CYA testing, then use the table
below to determine the amount to add. Note:
Indoor spas do not require the addition of CYA.

SPA SIZE CALCULATION
Use these three formulas to calculate the volume of water in the spa:
Rectangular:
Length(Ft) x Width(Ft) x Average Depth(Ft) x 7.5 = Total U.S. Gallons
Length(M) x Width(M) x Average Depth(M) x 1000 = Total Litres
Round:
3.14 x Radius(Ft) x Radius(Ft) x Average Depth(Ft) x 7.5 = Total U.S. Gallons
3.14 x Radius(M) x Radius(M) x Average Depth(M) x 1000 = Total Litres
Free Form:
Average Length(Ft) x Average Width(Ft) x Average Depth(Ft) x 7.5 = Total U.S. Gal.
Average Length(M) x Average Width(M) x Average Depth(M) x 1000 = Total Litres

Inspecting the Cell:
The cell should be inspected every 3 months. Unplug the Saltron MINI from the GFCI socket. Inspect the cell for scaling (white, sugar-like) deposit. If scaling
exists, the cell should be cleaned.
Cleaning the cell:
To clean the cell, a bucket or a large cup should be used. The bucket should be filled with 80% water and 20% muriatic acid. NEVER ADD WATER TO ACID,
only acid to water. It is recommended to wear safety goggles when handling the acid. Place the entire cell into the bucket for 20 minutes. Remove the cell and
do the inspection again. If the scaling remains, repeat the process. After the scale is removed, rinse the cell with fresh water. (See Fig.4)
