Spa Shell Care
General Cleaning
      For normal cleaning, use a mild dishwashing soap such as Ivory® liquid or a window cleaner such as Windex®. For stubborn stains, use a mild liquid cleaner such as Softscrub® or a mild detergent such as Spic And Span®. To apply these cleaners, use a soft, damp cloth or sponge. Rinse well and dry with a clean cloth. To clean hard water stains, remove light scratches and protect your spa shell, contact your authorized Bullfrog Spa dealer.

Cleaning the Scum Line
      With normal use of the spa, oils, lotions, and hair spray will build up on the surface of the water. This will leave a scum line around the perimeter. This can be easily removed using a spa surface cleaner or its equivalent. Avoid using cleaning agents that leave suds in the water.
      WARNING: Never allow your spa surface to be exposed to alcohol, acetone (nail polish remover), nail polish, dry cleaning solution, lacquer thinners, gasoline, pine oil, abrasive cleaners, or any other household chemicals other than those listed. These chemicals can void the warranty.

Plumbing Care
      At least twice a year, or every time spa water is changed, remove all Jet covers . Clean the plumbing on the back of the Jet pack with a spa surface cleaner and a long, soft bristle brush. For cleaning the Jet cover acrylic surface, refer to Spa Shell Care.

Spa Cabinet Care
The cabinet components are made to provide many years of maintenance-free service. For normal cleaning, use a mild dishwashing soap. For stubborn stains, contact your authorized Aqualotus Spa dealer.

Spa Cover Care
      Your spa cover is warranted by its manufacturer, 
      WARNING: A non-secured or improperly secured cover may pose a safety threat to children and may also cause damage or injury if blown off by wind. Always remove entire cover before using the spa.
      IMPORTANT: Do not stand, sit, or place any item on the cover that could damage it. Gently remove any snow accumulations over 2” (5.08cm). Do not use any cleaners other than those recommended by AQUALOTUS SPAS. Always secure the cover with all of the cover locks when not in use, whether the spa is empty or full of water. When Super Sanitizing your spa, always follow the cover care instructions provided in the Super Sanitation section.

Cleaning the Spa Cover
At least monthly, clean the spa cover.
Step 1: Remove the cover and lay it down on a flat, clean surface near a garden hose.
Step 2: Rinse the cover to remove any loose debris.
Step 3: Clean the top (vinyl) of the cover with a mild solution of dishwashing soap and a soft bristle brush. Using a gentle circular motion, scrub the cover, careful to not let any of the cover dry before rinsing with water.
Step 4: Rinse the cover thoroughly and dry with a clean cloth.
Step 5: Use saddle soap (never a petroleum-based product) to condition the cover per the manufacturer’s instructions.
Step 6: Wipe and rinse any dirt from the bottom of the cover.
Step 7: Replace the cover and secure the locks.
NOTE: To remove tree sap, use lighter fluid (the type used in cigarette lighters). Use sparingly. Immediately, apply saddle soap to the area.

Miscellaneous Care
      Cleaning and Protecting the Headrests
      Regularly, clean all headrests with mild soap, water, and a clean cloth. Monthly, use a non-petroleum-based product such as 303 Aerospace Protectant manufactured by 303 Products, Inc. This will maintain water resistance and luster of the product.

Vacuum the Spa
      Debris from wind, trees, and users will occasionally accumulate on the bottom of the spa. The filtration system will remove the smaller debris; however, debris that is too large or heavy will have to be removed by a spa vacuum. If you do not have a spa vacuum, contact your authorized AQUALOTUS SPAS dealer.
Freeze Prevention

      In regions where low temperatures fall below 5F (-15C), it is recommended that a 2” (5.08cm) insulation board or blanket be secured to the backside of the spa equipment compartment door.
IMPORTANT: When daytime outside temperatures reach 60F (15.6C), the equipment compartment insulation must be removed to prevent overheating of the equipment.

Low-Use or No-Use Periods
      During certain times of the year, you may not use the spa on a frequent basis. For these low-use or no-use periods, consider the following:
Low Use or No Use for less than Two Weeks
Do not make any changes.

No Use for Two to Six Weeks
      If the spa will not be used for at least two weeks, lower the temperature to the lowest setting of 80◦F (26◦C) or place in Sleep Mode. Lowering the temperature will cut the cost of operation, however; you will need to adjust the temperature setting approximately 4 hours before use in order to heat the spa to 100◦F (38◦C).
IMPORTANT: During all low- and no-use periods, be sure to maintain the spa water as per the instructions in the Water Chemistry section.
      IMPORTANT: For all no-use periods, and on a weekly basis, be sure to have someone visually check that the spa is functioning correctly and to also maintain the spa water as per the instructions under the Water Chemistry section. Not doing so may lead to corrosion, staining, and/or scaling to the spa and its equipment. During periods of freezing temperatures, a spa that has malfunctioned may be subject to damaged plumbing or equipment as a result of ice buildup within the spa. If the spa cannot be checked and maintained on a weekly basis, then consider winterization.

Winterization (No use for over six weeks)
      When you are not planning to use the spa for six or more weeks, or when someone is not able to maintain the spa on a weekly basis, you should winterize the spa. To winterize, follow these steps:
WARNING: Prior to winterizing your spa, it will be necessary to Super Sanitize the spa water as per the instructions in the Water Chemistry section. This procedure will help prevent the growth of bacteria, algae and fungi in any areas of plumbing that may not be fully free of water after you drain your spa for its period of winterization.
Step 1: Drain the water.
Step 2: Remove the drain plug from the pump(s), loosen all PVC pipe unions, and pump air-bleed valves in the equipment compartment. Do not replace the plugs, tighten the unions or close the air-bleed valves until the spa is de-winterized.
Step 3: Clean the entire spa.
Step 4: Remove filter cartridge and clean. Allow filter to dry fully and store in a dry place.
Step 5: Secure the cover to the spa utilizing the tie downs and locking system. In areas where heavy snow is anticipated, place a large piece of plywood (or its equivalent) on top of the spa cover to assist in supporting the cover with the added weight of the snow. Remove snow off the cover following each snow storm.
WARNING: To avoid water from becoming trapped between the floor suction fitting and the filter pipe close the slice valve in front of the pump leading to the filter. Use a wet/dry vacuum to remove the remaining water out of pipe by placing the vacuum end over the filter hole. In a two-pump spa, first plug off one filter then vacuum out the water. Or pour 1-2 gallons (4.55-9.09l) of RV antifreeze into the filter hole. NOTE: RV antifreeze is nontoxic and does not require evacuation at start up.

Spa De-Winterization
      To de-winterize the spa, reverse the Winterization procedure. Refill to the water level mark.
WARNING: Whenever refilling the spa, it will be necessary to Super Sanitize the new spa water. Instructions are found in the Water Chemistry section.
Initial Start-Up
• Do not plug in the spa when empty. Make sure that the water level is up to the skimmer. Use tap water only.
• Remove the air from the filter drain tube before plugging the spa into the electrical outlet.
• Do not interrupt the two to three minute test program.

Maintenance
• Change the spa water at least once every three months. Once every six weeks, wash the filter in the dishwasher, or soak it over night in the filter cleaner liquid. Please read the instructions carefully before using the filter cleaner liquid.
• Nature 2 (yellow) once every four months.

Chlorine
• The PH level needs to be between 7.2 and 7.6.
• If necessary, use PH- or PH+ to adjust the level. Please read the instructions carefully before using PH- or PH+.
• Proceed when the correct PH level is obtained. The chlorine level must be maintained.

Spa Cover
• Cover the spa when not in use (even when the spa is empty).

Cleaning
• Do not use shampoo, detergent, abrasive substances or oil to clean the spa.

Aromatherapy
• Use aromatherapy bags specifically designed for spas. Make sure the bags are placed in correct compartment.

Jet Maintenance
• Turn the jet counter clockwise until you hear it click. Remove and clean the nozzle. Put the jet back in and turn it clockwise to properly fix the nozzle.  Make sure to turn the jet completely in the clockwise direction in order to obtain maximum flow.
