LED CODE CHART

SPA WATER CHEMISTRY AND BALANCE

Water Chemistry Balance

Maintain the spa water pH level between 7.2 and 7.8, total alkalinity level between 80 and 120 ppm and free chlorine level between 2 to 4 ppm. Use the included test strips to test the spa water chemistry before each use of the spa and continue to test the water no less than once a week.

The Test Strips can test the “Free Chlorine”, “pH”, “Total Alkalinity” and “Calcium Hardness” levels at the same time:

1. Dip the entire strip into the water and remove immediately.
2. Hold the strip level for 15 seconds. Do not shake excess water from the strip.
3. Compare the strip pad to the color chart on the packaging label. If necessary, adjust the chemical level in the pool water.

NOTE: Check the expiry date of the test kit as the test results may be inaccurate if the kit is used after that date.

Low pH will damage the spa tub and pump. Damage resulting from chemical imbalance is not covered by the warranty.

Use the included chemical floater dispenser to administer chlorine [chemical tablet size: less than 1” (2.5 cm) diameter] into the spa water. Add 1 tablet into the dispenser. Always follow the chemical manufacturer’s directions. Remove the chemical floater dispenser when the spa is in use.

Never let chlorine come in contact with the spa tub if it is not completely dissolved.

Flush all pipes with treated water by activating the bubble function for an hour a day.

IMPORTANT: Press the button on the spa control panel to turn on the bubble air blower and help dissolve the chemicals into the water. Never mix chemicals together. Add the chemicals to the spa water separately.

Thoroughly dissolve each chemical before adding another one to the water.

Free chlorine: is the chlorine residual present in the spa water.

• Result if too low – Inadequate level of disinfection.
• Result if too high – cause odor problem, skin & eye irritation, corroded metals and other materials.

pH: a value that indicates how acidic or basic the spa water is.

• Result if too low – Corroded metals, eye & skin irritation, and destruction of total alkalinity.
• Result if too high – Scale formation, cloudy water, shorter filter/heater runs, eye & skin irritation, poor chlorine efficiency.

Total Alkalinity (TA): indicates the degree of the water’s resistance to pH change. It determines the speed and ease of pH change, so always adjust total alkalinity before adjusting the pH level.

• Result if too low – Corroded metals, eye & skin irritation. Low alkalinity will cause the pH to be unstable.
• Result if too high – Scale formation, cloudy water, shorter filter/heater runs, eye & skin irritation, high chlorine demand.

Calcium Hardness (CaCO3): refers to the amount of calcium and magnesium dissolved in the water.

• Result if too low – Difficulty balancing water, corrosion of metal components, eye & skin irritation and water foaming.
• Result if too high – Scale formation, cloudy water, eye & skin irritation, difficulty balancing water and filter/ heater inefficiency.

Saturation Index (SI): temperature, calcium hardness concentration, total alkalinity and pH represent the main factors influencing scale formation. The tendency of water to either form scale or corrode is indicated by the Saturation Index (SI):

SI = pH+TF+CF+AF-12.1

Where: TF = Temperature Factor; CF = Calcium Hardness Factor; AF = Total Alkalinity Factor

Test the water pH, Temperature, Calcium Hardness and Total Alkalinity levels. Use the equivalent Factors in the SI equation.

• SI = 0, Balance
• If SI > 0, Scaling or cloudy water condition.
• If SI < 0, Corrosive to metals or eye & skin irritating condition.
• The SI is considered satisfactory if the value is within -0.3 to +0.3 range. Zero being perfect

SPA Water Adjustment

How to adjust the spa water chemistry when the levels are off the range. CAUTION: Always follow the chemical manufacturer’s directions, and the health and hazard warnings.

Total Alkalinity (TA) Adjustment

Remove the spa cover to aerate the water and use the included test strips to check the chemistry level. Ensure the chlorine level in the water is between 2-4 ppm first, as chlorine will affect the TA test result.

• If the TA level (and not the pH) is higher than 120 ppm, to lower the TA level, you add muriatic acid (hydrochloric acid) or sodium bisulfate.
• If the TA level is lower than 60 ppm, you add sodium bicarbonate.
  • For example (for 4 adults’), if the TA level is 180 ppm, the desired decrease is 60 ppm, from below chart, you need to add 0.269 Lb (121 g) of sodium bisulfate or 0.101 qt (96 ml) of muriatic acid.
• If the test strip color is between 180 ppm and 240 ppm, and close to 180 ppm, you can also add 0.269 Lb g) of sodium bisulfate or 0.101 qt (96 ml) of muriatic acid.
• If the reading is more than 240 ppm, you can add sodium bisulfate or muriatic acid to the water drop by drop until the test strip indicates a 240 ppm reading, then add 0.528 Lb (238 g) of sodium bisulfate or 0.202 qt ml) of muriatic acid.

NOTE: After adjustment, retest the water after 24 hours and adjust again if necessary.

Calcium Hardness Adjustment

Use the included test strips to check the water hardness level and adjust it following below chart.

Lowering Calcium Hardness

If your household water supply is treated with a softener, mix the spa hard water with the soft water according to the water volume ratio chart to lower the calcium hardness:

Lowering Calcium Hardness Using Soft Water

Raising Calcium Hardness

If the calcium hardness level in the spa water is lower than 100 ppm, add calcium chloride into the spa water.

WARNING Muriatic acid is a caustic chemical and liquid solution of sodium bisulfate (NaHSO4) is highly acidic. Handle all chemicals with care and wear extra personnel protective equipment including goggle and gloves. It is very important not to splash acid onto your skin or clothing, or into your eyes.

MAINTENANCE

WARNING Always unplug this product from the electrical outlet before removing, cleaning, servicing or making any adjustment to the product.

Water Sanitation

The spa owner must regularly check and keep the spa water sanitized with scheduled maintenance (daily, if necessary). Adding sanitizer and other chemical will control bacteria and viruses present in the spa water.

The maintenance of a proper water balance through appropriate use of sanitizers is the single most important factor in maximizing the life and appearance of the spa tub as well as ensuring clean, healthy and safe water.

Proper technique is important for water testing and treating the spa water. See your pool/spa professional for chemical, sanitizer, test kits and testing procedures questions.

CAUTION: ALWAYS FOLLOW THE CHEMICAL MANUFACTURER’S DIRECTIONS, AND THE HEALTH AND HAZARD WARNINGS.

Do not add chemicals if the spa is occupied. This can cause skin or eye irritation. Concentrated chlorine solutions can damage the spa tub. In no event is Intex Recreation Corp., Intex Development Co. Ltd., their related companies, authorized agents and service centers, retailers or employees liable to the buyer or any other party for costs associated with the loss of spa water, chemicals or water damage.

Maintenance of Spa Water and Cartridge

Protect all the spa occupants from possible water-related illnesses by keeping the spa water clean and sanitized.

Always practice good hygiene. To ensure proper spa water quality follow these procedures:

1. Inspect and clean the filter cartridge once a week, and change the filter cartridge as needed.
   1. Unscrew the cartridge housing assembly from the spa tub wall and remove the cartridge (see drawing 12).
   2. Use a garden hose to rinse off the cartridge. If the cartridge remains soiled and discolored it should be replaced. Keep spare cartridges on hand.
   3. Reinstall the clean cartridge back into the cartridge housing and replace the cartridge housing assembly back onto the spa tub wall.
2. Change the spa water every 2~3 months, or it becomes cloudy and proper water chemistry does not clear it up. See “Spa Tub Drainage” and “Spa Tub Cleaning” sections for details.
3. Use spa chemicals to maintain proper water chemistry. Spa damage resulting from misuse of chemicals and mismanagement of spa water is not covered by the warranty.
4. All occupants must shower before entering the spa.

Spa Tub Drainage

1. Turn off the spa control unit.
2. Connect the drain valve adaptor to a garden hose and point the other end of the garden hose to a suitable draining area (see drawing 13).
3. Remove the drain valve cap from outside of the spa tub and attach the drain valve adaptor to the drain valve (see drawing 13).
4. From inside of the spa tub, open the drain valve cap, water will start flowing out from the garden hose.
5. When the water stops draining, disconnect the spa control unit from the spa tub wall. Lift the spa tub wall from the side opposite the drain, leading any remaining water to the drain and emptying the spa completely see drawing 14).
6. Attached the inflation hose (7) to the air blower inflation outlet on the control unit.
7. Turn on the spa and press the button, aim the inflation hose at the inlet/outlets on the spa tub and spa control unit to dry out any water in the piping system (see drawings 15 & 16).
8. Use a clean towel to wipe up any remaining water and moisture on the spa tub and spa control unit.
9. Ensure the spa tub and spa control unit are thoroughly dried.

NOTE: The enclosed plugs (15) can be used to cover the water inlet and outlet connectors from the inside of the spa tub to prevent water from flowing out.

Spa Tub Cleaning

If dirt is visible in the water or water becomes cloudy and proper water chemistry does not clear it up, change the water and clean the spa tub.

While empty, remove the cartridge housing from inside of the spa tub wall, clean and/or replace the filter cartridge. Use a sponge and mild soap solution to wipe away any soil or stains on the inside of the spa wall. Rinse thoroughly before refilling with clean water.

IMPORTANT: Do not use steel wool, hard brushes or abrasive cleaners.

Biofilm Removal

See your local spa professional for biofilm removal products and advice.

Spa Tub Air Valve Fastening

1. Check the spa tub air valve for leakage and tightness before use. If air is leaking from the air valve, use the provided wrench (22) to tighten the air valve as follow:
2. Make sure the spa tub is deflated, open the air valve cap and insert the wrench (22) into the air valve body (see drawing 17).

With one hand, hold the backside of the air valve base from the inside of the spa tub wall and turn the wrench (22) clockwise.

IMPORTANT: Never adjust the air valve base when the spa is in use or filled with water. Only use the air valve wrench if the air valve is loose or there is leakage around air valve base. Do not over tighten the air valve: over tightening can damage the valve. Just ensure the air valve is snug and not leaking.

Spa Cover

The attachment buckles of the cover are locking buckles. Two keys are provided in the plastic bag with the manual and other accessories. Each buckle is marked with “locked” and “unlocked” symbols for easy operation: put the key into the slot on the buckle and turn it to the appropriate position to lock or unlock the buckle respectively.

To assure safety from unauthorized access, always put the cover on when spa is not in use and lock all buckles. Always keep the keys out of reach of children. In case you misplace the keys, you can use any similar size flat screwdriver to lock or unlock the buckles.

Inspect the spa cover regularly for leaks, premature wear and tear, damage, or signs of deterioration. Never use a worn or damaged cover: it will not provide the level of protection required to prevent unsupervised access to the spa by a child.

Spa Tub and Cover Air Bladder Repair

Use the enclosed repair patch to repair any puncture:

• Clean and dry the area to be repaired thoroughly.
• Remove the patch backing paper and press patch firmly over the puncture. Smooth out the surface to remove any air bubbles under the patch.

STORAGE

1. In regions subject to freezing temperatures, drain, clean, disassemble and properly store the spa set and related components indoors when the temperature drops below 39°F (4°C).
2. Drain and clean the spa following the “Spa Tub Drainage” and “Spa Tub Cleaning” sections. Reverse set up instructions to deflate and disassemble the spa tub, spa control unit and spa cover air bladder.
3. To deflate the tub and the cover air bladder:
   1. Open the defation outlet cap (27) with the included bolt wrench (6) (see drawing 18).
   2. Insert deflation hose adaptor (28) into the deflation outlet.
   3. Insert inflation hose (7) over the deflation hose adaptor (28).
   4. Insert the other end of the inflation hose into the tub air valve or cover air bladder valve.
   5. Press the air bubble button to deflate.
