SAFETY INFORMATION IMPORTANT SAFETY INSTRUCTIONS READ AND FOLLOW ALL INSTRUCTIONS AVOIDING THE RISK TO CHILDREN DANGER: • RISK OF CHILD DROWNING. Extreme caution must be exercised to prevent unauthorized access by children. To avoid accidents, ensure that children cannot use a spa unless they are supervised at all times. WARNING: • To reduce the risk of injury, do not permit children to use this product unless they are closely supervised at all times.
SAFETY INFORMATION DANGER: RISK OF ELECTRICAL SHOCK • Install spa at least 5 feet (1.5 m) from all metal surfaces. A spa may be installed within 5 feet of a metal surface if each metal surface is permanently connected by a minimum No. 10 AWG solid copper conductor attached to the wire ground connector on the terminal box that is provided for this purpose if in accordance with National Electrical Code ANSI/NMFPA70-1993.
SAFETY INFORMATION TO REDUCE THE RISK OF INJURY: • The water in the spa should never exceed 104°F. Water temperatures between 100°F and 104°F are considered safe for a healthy adult. Lower water temperatures are recommended for extended use (exceeding 10 minutes) and for young children. Extended use can cause hyperthermia. • Pregnant or possibly pregnant women should limit spa water temperatures to 100°F. Failure to do so may result in permanent injury to your baby.
INSTALLATION SITE PREPARATION You probably have a spot picked out for your new spa, whether it’s indoors or outdoors, on a patio or on a deck. Just make sure you check the following: • Always put your spa on a structurally sound, level surface. A filled spa can weigh a great deal. Make certain that the location you choose can support the weight of your filled spa. • Don’t forget to level your spa before filling it.
ELECTRICAL INSTALLATION SELECTING THE VOLTAGE FOR YOUR SPA Your spa is designed to operate at either 115 or 230 volts, 60 Hz, unless it is the Olympia model which requires a dedicated 230 volt power supply. When the spa is connected to 115 volts, the heater will provide approximately 1000 watts of heat only when the pump is operating in LOW speed and the thermostat is calling for heat.
ELECTRICAL INSTALLATION 230 VOLT SUBPANEL WIRING INSTRUCTIONS NOTE: The subpanel must be placed within 100 feet of the main electrical service panel, and between 5 and 50 feet away from the spa. All electrical connections must be made in accordance with the wiring information contained in this manual and on the back of the field wiring access panel of the control box. Refer to the wiring diagram below. 1.
START-UP AND REFILL PROCEDURES Your Caldera® spa has been thoroughly tested during the manufacturing process to ensure reliability and long-term customer satisfaction. A small amount of water may have remained in the plumbing after testing and, as a result, may have spotted the spa shell or the spa siding prior to delivery. Before filling the spa, wipe the spa shell clean with a soft rag. The following instructions must be read and followed exactly to ensure a successful start-up or refill.

OPERATING INSTRUCTIONS SPA-SIDE CONTROL OPERATION Set Temperature Display Your spa-side control panel consists of an LED display and convenient touch pads that allow you to set the water temperature and adjust the skim/filter cycle settings, as well as control the hydrotherapy jets, and light from spa-side. Filter Cycle LED Jets LED Light LED LED DISPLAY The LED display on your spa-side control panel continually shows the spa’s actual water temperature.
OPERATING INSTRUCTIONS FILTER CYCLES Your spa will automatically turn the filter cycle on twice each day. When the spa is first powered up the automatic filter cycle will wait 12 hours before starting. A six hour filter cycle using the low speed of the jet pump is the programmed default filter cycle time. The filter cycle occurs twice a day (every 12 hours). NOTE: The optional MonarchTM and PureWaterTM ozone systems only work during the filter cycles. To modify the length of the filter cycle: A.
WATER QUALITY AND MAINTENANCE It’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 WARNING: High sanitizer levels can cause discomfort to the user’s eyes, lungs and skin. Always allow the sanitizer level to fall to the recommended range before using the spa. IMPORTANT “SUPER CHLORINATION/NON-CHLORINE SHOCK TREATMENT” NOTE: After administering a super chlorination treatment or non-chlorine shock to your spa, leave the cover open for a minimum of 20 minutes to allow the oxidizer gas to vent.
WATER QUALITY AND MAINTENANCE E. It is important to check the pH on a regular (weekly) basis. The pH will be affected by the bather load, the addition of new water, the addition of various chemicals, and the type of sanitizer used. 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.
WATER QUALITY AND MAINTENANCE 2. Remove the filter compartment cover. 3. Make sure the filter compartment is clear of any floating objects. 4. Drain the spa using the recommended procedures found in the Owner’s Manual. PLEASE NOTE: The MonarchTM silver cartridge cannot be used with bromine, sodium bromide or biguanides. If you have previously used any of these products in the spa, it is recommended that the shell and filter compartment be cleaned.
WATER QUALITY AND MAINTENANCE F. When the Free Available Chlorine is within the recommended range, the spa is ready to be enjoyed. WARNING: There are several forms of stabilized chlorine available for use in spas and swimming pools and each form has specific chemical characteristics. It is extremely important that the one you choose is specifically designed for use in spas. Use of an incorrect product such as tri-chlor, which has a very low pH (2.
WATER QUALITY AND MAINTENANCE NOTE: Well water may contain high concentrations of minerals. The use of a low water volume, extra-fine pore water filter will help to remove many of the larger particles during the filling of the spa. Foam Inhibitors Spa water requires changing due to the buildup of soap in the water. Typically, soap will cause the spa water to foam when the jets are used.
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 misuse 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 known to cause discoloration of or surface distress to a spa’s shell.
WATER QUALITY AND MAINTENANCE scaling. Low levels can cause harm to the spa equipment. 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.
MAINTENANCE FILTER MAINTENANCE At least once a week, check and clean the skimmer basket and weir to ensure proper filter flow. Remove leaves, foreign matter, and debris. It is very important to keep your spa filter cartridge clean and free of particles to ensure proper water flow. A clean filter permits the hydrotherapy system to function properly and also allows more efficient filter cycles. Depending on how frequently your spa is used, we recommend cleaning the spa filter cartridge every four weeks.
MAINTENANCE CARE OF THE EXTERIOR SPA SHELL Your Caldera® spa has a granite like shell. Stains and dirt generally will not adhere to your spa’s surface. A soft rag or a nylon scrubber should easily remove most dirt. Most household chemicals are harmful to your spa’s shell. Watkins® Manufacturing Corp. recommends Soft Scrub® and Windex®. These are the only products which have passed the manufacturer’s tests. Sodium bicarbonate (baking soda) can also be used for minor surface cleaning.
MAINTENANCE DRAINING YOUR SPA DRAIN CAP 1. TURN OFF OR DISCONNECT POWER FROM THE SPA. 2. Remove the equipment compartment access door. 3. Locate the drain cap. Lift drain hose above the water level.(requires cutting plastic tie the first time.) 4. Unscrew and remove the drain cap. 5. Attach drain hose to garden hose and direct to an appropriate draining area. Maintain hose below water line. 6. After your spa is empty, clean the shell and filter cartridge. DRAIN HOSE 7.
SERVICE ACTS INVALIDATING WARRANTY The limited warranty is void if the Caldera® spa has been improperly installed, subjected to alteration, misuse, or abuse, or if any repairs on the spa are attempted by anyone other than an authorized representative of Watkins® Manufacturing Corporation.
