Spa Water Preparation & Monitoring
Section 1 b
STEP 1 - Proper Water Balance Requirements:
Proper EcoClean System operation is dependent on proper spa water conditions. Manually balance the SPA
water chemistry to meet all suggested ranges of water balance factors listed below before start-up of the
EcoClean unit. From that point forward your EcoClean System will assist you in keeping your water
chemistry factors in balance.
BEFORE START UP, MAKE SURE THE SPA WATER MEETS THE FOLLOWING REQUIREMENTS:ALL WATER
BALANCE FACTORS SHOULD BALANCE WITH LANGELIER'S SATURATION INDEX. WE RECOMMEND A VISIT TO
YOUR LOCAL SPA PROFESSIONAL.
EcoClean System Required Ranges (And periods for testing water for these water balance factors.)
STEP 2 - Daily Checks
4) Total Alkalinity 80 - 120 ppm
1) Free Available Chlorine = 3.0 – 5.0 ppm
-
5) Cyanuric Acid 30-100 ppm (Outdoor)
2) Free Available Bromine = 3.0 – 5.0 ppm
-
6) Salt Residual 2800-3200 ppm
3) Calcium Hardness 150 – 200 ppm
7) Langelier's Index (water balance) + or - 0.3
8) pH 7.2-7.8 (
NOTE: Check expiry date of the test kit as test results may be inaccurate if used after that date.)
STEP 3 - Monthly Checks: CAUTION: Excessive Free Available Chlorine(>5.0 ppm) or Free Available
Bromine (> 5.0 ppm) causes corrosion of any metal components in contact with spa/hot tub water.
Staining and premature failure of heaters, filters, and other metal components will be the result. Do not
exceed recommended sanitizer ranges. NOTE: Standard (DPD) pool water test kits do not read
chlorine/bromine levels above approximately 8.0 ppm. Test reagents, at high levels, return to a clear
liquid. AVOID HIGH SANITIZER LEVELS!
STEP 4 - Salt Requirements: It is important that a suggested salt level of 3000 ppm be maintained at all
times. Allowing less than 2800 ppm salt will activate a double flashing red CHECK SYSTEM light and stop
sanitizer generation. The amount of salt required depends on the size of the spa/hot tub. Use the chart on
the next page to determine the amount of salt to add, in pounds or kilograms, for a new spa/hot tub start
up. Also test your make up water for its level of salt and compare it with the charts on the next page.
Before adding salt to a spa/hot tub for the first time, turn your EcoClean unit OFF, then pour salt around
the perimeter of the spa.
NOTE: Homeowners with water softening/treatment equipment, which utilize salt, may already have sub-
stantial levels of salt in their drinking water. So before adding this water to your spa, test the level of
salt, then determine the amount of salt still needed to be added to bring the level up to the suggested
3000 ppm start-up level. Before adding any make-up water to your spa, it is suggested that pre-testing
the make-up water for high pH, total alkalinity and calcium hardness will aid in the adjustment of these
levels before they become excessive.
NOTE: Maintaining constantly high levels of salt and bromine above the recommended range can contribute to
corrosion of the pool equipment. Salt levels exceeding the recommended concentration can be reduced by
diluting the spa water with fresh water. NOTE: Heavy uses of the spa (excessive contamination) may require
longer recovery times (a return to a minimum of 3 ppm bromine). Recovery time may be reduced by adding a
shock compound to the water. Follow instructions of the shock compound being used.
MANUAL CLEANING OF CELLS
In normal conditions the EcoClean unit should not require Manual Cleaning. If manual cleaning is required,
check water chemistry for possible imbalances or call the factory for consultation, and use the following
procedure:
STEP 1 - Remove the cell.
STEP 2 – Using a bucket, add 1 part muriatic acid to 4 parts of water. PUT WATER IN BUCKET FIRST!
CAUTION: Always add acid to
WATER,
never water to acid.
STEP 3 - Submerge the cell in the solution.
STEP 4 - After 10 - 15 minutes of foaming, remove the cell. Rinse with fresh water.
STEP 5 - If cell blades still have white crusty scale deposits on them, repeat the process, not to exceed 15
minute intervals.
NOTE: DO NOT try to remove any scale from cell blades with any tools. This may scratch or damage the
coating on the blades and will VOID WARRANTY. The electrolytic cell has a life expectancy of 2 to 4
years under typical conditions of use. When replacing the cell, only use replacement cells having a label
that clearly states that it is a replacement cell for the chlorine generating device EcoClean ,
