UTOPIA SERIES PARADISE SERIES The CANTABRIA,, GENEVA and NIAGARA spas are equipped with 4 directional neck jets located in the ECSTASEAT. The flow of the neck jets is regulated by turning the ATLAS NeckJet valve on the inside wall of the spa.
AIR JETS The air jet system consists of a 1 HP air pump and 14 air jets on the CANTABRIA or 10 air jets found only on GENEVA, NIAGARA, and TAHITIAN spas. The air jets deliver air bubbles to provide subtle pulsation for a gentle, soft-tissue massage.

UTOPIA OPERATING INSTRUCTIONS MAIN CONTROL PANEL The main control panel provides a quick visual check of the spa’s status and allows the user to set the temperature, activate the jets & lights, lock the temperature and/ or spa functions. Other optional functions may also be available depending on the spa model and accessory equipment that has been installed into the spa. The main control panel has eight buttons.
UTOPIA OPERATING INSTRUCTIONS Spa or Temperature Lock Indicator: The Spa or Temperature Lock indicator is displayed when either the Spa Lock, Temperature Lock or both are activated. Lock indicator does not flash. Jet Pump Indicator: The Jet Pump indicator is displayed whenever a jet pump is on. The Jet Pump indicator will flash whenever the spa is in the ten-minute Clean Cycle or Auto Clean Cycle.
UTOPIA OPERATING INSTRUCTIONS LOCKING FEATURES The two locking features, Temperature Lock and Spa Lock, are activated at the main control panel. Once activated, a lock will remain active until the specific button combination is pressed to disable the lock. Even if power to the spa is disconnected even briefly, the lock will remain activated. TEMPERATURE LOCK When activated, the Temperature Lock feature prevents a change in your desired water temperature setting.
LOUNGE JETS (CANTABRIA MODEL ONLY) The Lounge Jets option will only be displayed if you own a CANTABRIA spa. This option is used to turn the Lounge jet pump On and Off. To access Lounge Jet option, press the JETS hard button to enter the Jets Screen then press the soft button next to Lounge Jets to activate the Lounge jet pump.
UTOPIA OPERATING INSTRUCTIONS ADDITIONAL FUNCTIONS SUMMER TIMER Your spa is equipped with a summer timer. The summer timer can be activated during hot summer months to maintain water temperature. Activating the summer timer causes the heater to immediately shut down. The circulation pump will remain on for approximately 5 minutes pushing water through the heater to cool it down. Both heater and circulation pump will then remain off for eight hours.
UTOPIA OPERATING INSTRUCTIONS AUDIO CONTROL (OPTIONAL WIRELESS SYSTEM ONLY) The following applies to spas that have CALDERA wireless sound system installed: When the sound system has been installed on the spa, the control panel can be used to control the music system.

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.
MAINTENANCE VERSASSAGE JETS MAINTENANCE If you notice that the VERSASSAGE jets spin slower than when the spa was new, or the jets are sticking, the cause could be a build-up of deposits inside the jet bearings. To remove the deposits, use the following instructions: With the spa off, rotate the VERSASSAGE jet face counter-clockwise until it stops.
MAINTENANCE Remove the filter cartridge, clean and store in a dry place. IMPORTANT: These additional instructions must be utilized when draining and winterizing your spa in climates where the temperature falls below 0°C (32°F). A 19 liter (5) gallon combination (vacuum/blower) wet/dry shop vac must be used to effectively remove water that is trapped inside the plumbing lines. If your spa is equipped with a blower, evacuate water from the air jet lines as follows: a) Turn on the 25A breaker.
MAINTENANCE CARE OF THE EXTERIOR SPA SHELL Your CALDERA spa has an acrylic 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 (see below for detailed information on cleaning agents). Always rinse off any spa shell cleaning agent with fresh water.
WATER QUALITY AND MAINTENANCE WATER TERMINOLOGY The following chemical terms are used in this Water Quality and Maintenance section. Understanding their meaning will help you to better understand the water maintenance process. Bromamines: Compounds formed when bromine combines with nitrogen from body oils, urine, perspiration, etc. Unlike chloramines, bromamines have no pungent odor and are effective sanitizers.
WATER QUALITY AND MAINTENANCE METHODS FOR TESTING THE SPA WATER Accurate water testing and analysis is an important part of effectively managing your spa water. You must have the ability to test for: • Total Alkalinity (TA) • Calcium Hardness (CH) •...

WATER QUALITY AND MAINTENANCE C. If the TA is too low, the pH level will fluctuate widely from high to low. Fluctuations in pH can cause corrosion or scaling of the spa components. Low TA can be corrected by adding sodium hydrogen carbonate (pH/Alkalinity Up). D.

WATER QUALITY AND MAINTENANCE WATKINS WATER TREATMENT GUIDE At spa startup or refill Follow spa Start-Up and Refill Procedures. Prior to each use Add one (1) tablespoon of MONARCH MPS (monopersulfate)* per 950 liters. (Test before adding any chemicals; do not add any chemicals if proper or higher levels are found.) Once a week Add three (3) tablespoon MONARCH MPS (monopersulfate)* per 950 liters.
WATER QUALITY AND MAINTENANCE WARNING: There are several forms of stabilized chlorine available for use in spas and swimming pools and each form has CHLORINE DO NOT USE specific chemical characteristics. It is extremely important that the one you choose is specifically designed for use in spas. Use DPD TEST KIT THE SPA UNTIL of an incorrect product such as tri-chlor, which has a very low pH (2.6), dissolves too quickly in hot water resulting in extremely...

WATER QUALITY AND MAINTENANCE Carefully loosen the long clear tubing to the bottom of the ozonator. A liquid substance may be found inside the tubing. If a liquid substance is present, BE CERTAIN NOT TO COME INTO CONTACT WITH THE LIQUID (SEE WARNING ON THE NEXT PAGE). Place the end of the tubing into the vinegar, making certain that the end of the tubing sits at the bottom of the container.
WATER QUALITY AND MAINTENANCE COMMON WATER CHEMISTRY QUESTIONS Question: Why is the use a floater not recommended to sanitize my spa water? Answer: Watkins Manufacturing Corporation does not recommend the use of a floater for three reasons: The floater is unable to control the rate at which the sanitizer is dissolved into the water. When a floater is first placed in a spa, the sanitizer level can be extremely high.
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.
