MAINTENANCE WINTERIZING YOUR SPA SCREW If you wish to leave your spa empty and it is located where freezing temperatures occur, follow steps 1 thru 5 outlined in “Draining your spa” then complete the following steps: INTAKE NOTE: Make certain all power to the spa is OFF before you continue. 1.
MAINTENANCE DRAINING YOUR SPA DRAIN CAP 1. Trip all GFCI breakers in sub-panel, or main electrical panel. 2. Remove the equipment compartment access door. 3. Locate the end of the drain hose and lift it above the water level. (Requires clipping plastic tie the first time.) 4.
MAINTENANCE CARE OF THE SPA PILLOWS The spa pillows will provide years of comfort if treated with care. They have been positioned above the water level to minimize the bleaching effects of chlorinated water and other spa water chemicals. To extend their life, whenever the spa shell is being cleaned, the spa pillows should be removed and cleaned. Body oils can be removed with a mild soap and water solution.
WATER QUALITY AND MAINTENANCE V. Water Quality And Maintenance t’s important to have clean water. Water maintenance is one of the least understood, yet most important areas of spa ownership. Your dealer can guide you through the process of achieving and maintaining perfect water in your spa, given your local conditions. Your program will depend on your water’s mineral content, how often you use your spa, and how many people use it.
WATER QUALITY AND MAINTENANCE 4. Replace the filter compartment cover (if applicable). After ten minutes, shut off the jet pump(s) and close and lock the cover to complete the procedure. Risk of Drowning: Never leave an open spa unattended! WARNING: High sanitizer levels can cause discomfort to the user’s eyes, lungs and skin. Always allow the sanitizer level to fall to the recommeded range before using the spa.
WATER QUALITY AND MAINTENANCE F. When the pH is within the recommended range, proceed to the final step. MAINTAINING THE SANITIZER LEVEL A. Sanitizer is extremely important for killing algae, bacteria and viruses, and preventing unwanted organisms from growing in the spa. At the same time, you don’t want too high a sanitizer level, or it can irritate your skin, lungs and eyes.

WATER QUALITY AND MAINTENANCE SUPER CHLORINATION Super Chlorination is designed to “burn-off” the build-up of chloramines (used chlorine), to eliminate the chlorine smell and to allow the proper level of free chlorine to be maintained. When giving your water a super chlorination treatment, open the cover at least half way for twenty minutes to allow the chlorine gas to vent off. The high concentration of chlorine gas which may exist as a result of super chlorination (not daily sanitation) may eventually cause discoloration or degradation to the bottom of the cover or the tile grouting, which would not be covered under the terms of your warranty.

WATER QUALITY AND MAINTENANCE Foam inhibitors can suppress foam, but cannot remove soap from the water. Soap is very difficult to remove from the water because soap is not oxidized by any chemical added to the spa. Only ozone can oxidize soap. Eventually the soap build-up in the water will be concentrated, resulting in an unclean feeling on the bather’s skin which is impossible to remedy.
WATER QUALITY AND MAINTENANCE DOS AND DON’TS • DON’T use swimming pool (muriatic) acid to lower pH. • DON’T splash pH increaser additives on the siding. • DON’T use Compressed Sanitizers. The use of bromine sticks or tablets in floaters, which may become entrapped in a lounge or cooling seat (or sink to the spa floor), have been shown to cause discoloration of or surface distress to a spa’s shell.
WATER QUALITY AND MAINTENANCE Chloramines: Compounds formed when chlorine combines with nitrogen from body oils, urine, perspiration, etc. Chloramines can cause eye irritation as well as having a strong odor. Unlike bromamines, chloramines are weaker, slower sanitizers. Chlorine: An efficient sanitizing chemical for spas. Watkins Manufacturing Corporation recommends the use of Sodium Dichlor-type granulated chlorine. This type is preferred because it is totally soluble and nearly pH neutral.

SERVICE MISCELLANEOUS SERVICE INFORMATION The control and high limit thermostats are equipped with electronic sensors that are connected to the spa’s plumbing. Never cut or kink the wires that connect the sensors to the thermostats within the control box. The jet pump is equipped with a thermal overload cutoff switch that is designed to protect the pump from overheating. If the pump shuts itself off in an older spa, it could indicate failure of the pump motor bearings.
