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 2,200L (600 gallons) of spa water (or up to 5700 L (1500 gallons) Swim Spa water).

Follow all aspects of the local and National Electrical codes when installing Saltron Mini (Model No.CLG020A)
Health and Hyperthermia warnings for spa devices:
People with a medical condition should consult a physician before entering pool or spa water.”
Maximum spa water usage temperature is 40°C. Bathing in spa water at 40°C should not exceed 15 minutes.”

INSTALLATION AND OPERATION

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. Add the required free chlorine residual before startup to have balanced water.
V.Place the cell in the spa (anywhere below the waterline, preferably one foot under).
IV. Plug the Power Supply into an 110VAC/220 VAC GFCI protected outlet.
NOTE: The spa chemistry must be balanced before installing the system to the spa. (see pg 9 )
During startup, add chlorine between 2-4 ppm as a 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 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.

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.
CHLORINE ADJUSTMENT

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 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 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

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 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 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(M) x Width(M) x Average Depth(M) x 1000 = Total Litres
Length(Ft) x Width(Ft) x Average Depth(Ft) x 7.5 = Total U.S. Gallons
Round:
3.14 x Radius(M) x Radius(M) x Average Depth(M) x 1000 = Total Litres
3.14 x Radius(Ft) x Radius(Ft) x Average Depth(Ft) x 7.5 = Total U.S. Gallons
Free Form:
Average Length(M) x Average Width(M) x Average Depth(M) x 1000 = Total Litres
Average Length(Ft) x Average Width(Ft) x Average Depth(Ft) x 7.5 = Total U.S. Gal.

UNIT MAINTENANCE

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, make sure the power supply is not plugged into the socket. A large cup should be used. Fill the cup with enough white vinegar to submerge the entire cell. Place the entire cell into the cup for 20 minutes. Remove the cell and make sure all scaling is gone. If the scaling remains, repeat the process. After the scale is removed, rinse the cell with fresh water. (See Fig.4)
