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: •...
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. •...
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.
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.
7. Connect the #8 AWG, RED [L2] wire from the subpanel breaker to terminal [L2] on the spa’s control box. 8. Bond the spa to all exposed metal equipment or fixtures, handrails, and concrete pad pre N.E.C. and all local codes. 230 Volt Permanently Connected (Olympia Spa Model Jumper Configuration) PINS 1 2 3...
90°F, proceed to the next step. 7. Press the Jets button twice (three times for Olympia) and run the pump on high for 10 minutes to circulate the spa water. After the filter cycle is complete, test the spa water for Free Available Chlorine (FAC) residual.

OPERATING INSTRUCTIONS SPA-SIDE CONTROL OPERATION Filter Jets Light Set Temperature Your spa-side control panel consists of an LED display and convenient touch Cycle LED Display 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.
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 Monarch and PureWater ozone systems only work during the filter cycles.
1. Fold back the cover. Carefully remove and set aside the filter compartment cover (if applicable). 2. Press the “JETS” button twice (three times for Olympia) to turn the jet pump on high. 3. Carefully measure the recommended amount of chemical and slowly pour it into the filter compartment. Use care not to splash chemicals on your hands, in your eyes, on the spa shell surface or on the siding.
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.
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 Monarch 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.
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.
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.
CARE OF THE SPA PILLOWS The spa pillows used on the Olympia and Cascade models 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.
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 ®...
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.
