CalderaSpas CalderaSpas Utopia Series User manual

Please take the time to read this booklet carefully, as it will provide you with the information you will need to ensure
the safe, secure, and timely installation of your new spa. The following sections are guidelines on how to prepare for
delivery and set-up of your new spa. Specifically covered are site selection, delivery access, ground preparation, and
electrical requirements.
Remember to carefully read the Owner’s Manual that accompanies your spa and to complete the warranty card
within ten days of delivery. These items, along with other valuable information, are included in the Owner’s Packet
which can be located in the equipment compartment of your spa. You will also find your serial number in the
equipment compartment.
Watkins Wellness™ reserves the right to change features, specifications, and design without notification and without

In most cities and counties, permits will be required for the installation of electrical circuits or the construction of
exterior surfaces (decks and spa enclosures). In addition, some communities have adopted residential barrier codes
which may require fencing and/or self-closing gates on the property to prevent unsupervised access to a pool (or
spa) by children under 5 years of age. Your Caldera®spa is equipped with a locking cover that meets the ASTM
F1346-91 Standard for Safety Covers, and as a result, is usually exempt from most barrier requirements. As a
general practice, your local Building Department will inform you of any applicable barrier requirements at the time a
permit is obtained for the installation of an electrical circuit. Your CALDERA dealer can provide information on which
permits may be required.

SITE SELECTION AND PREPARATION
IMPORTANT: Site selection and preparation are your responsibility. Carefully read these instructions and consult
your authorized CALDERA dealer if you have any questions.
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. (See the Ground and Spa Leveling Preparation section on the next page.)
• Locate your equipment compartment, which houses all of the electrical components, in a place where
water will drain away from it. Allowing water into the equipment compartment can damage the electronics,
or may result in tripping your house’s circuit breaker.
• Leave yourself easy access to the circuit breakers in the subpanel.
• Never let water get into the subpanel. Your 230 volt spa’s subpanel is raintight when installed correctly
with the door closed.
• Leave access to the entire front of the spa (the removable panel provides access to the spa’s equipment)
for periodic spa care and maintenance.
INDOOR/BASEMENT INSTALLATION
Be aware of some special requirements if you place your spa indoors. Water will accumulate around the spa, so
flooring materials must provide a good grip when wet. Proper drainage is essential to prevent a build-up of water
around the spa. When building a new room for the spa, it is recommended that a floor drain be installed. The
humidity will naturally increase with the spa installed. Water may get into woodwork and produce dry rot, mildew, or
other problems. Check for airborne moisture’s effects on exposed wood, paper, etc. in the room. To minimize these
effects, it is best to provide plenty of ventilation to the spa area. An architect can help to determine if more ventilation
must be installed.
CALDERA spas are equipped with a jet pump shroud to remove excessive heat from the equipment compartment.
Find this vent, and be sure it is not blocked by anything, including carpeting.
Your CALDERA dealer can help you with local information such as zoning regulations and building codes.
DECK INSTALLATION
To be certain your deck can support your spa, you must know the deck’s maximum load capacity. Consult a
qualified building contractor or structural engineer before you place the spa on an elevated deck or indoors. To find
the weight of your spa, its contents and occupants, refer to the Spa Specification chart (on back cover). This weight
per square foot must not exceed the structure’s rated capacity, or serious structural damage could result.
OUTDOOR AND PATIO INSTALLATION
No matter where you install your new spa, it’s important that you have a solid foundation to support it. Structural
damage to the spa resulting from incorrect installation or placement on an inadequate foundation is not covered
under the spa’s limited warranty. (See next page for specifics)
GROUND AND SPA LEVELING PREPARATION
Your CALDERA spa has been engineered to perform on several types of common yard surfaces. While a concrete
slab is best for long-term use*, other foundations are acceptable as long as a level base is prepared prior to delivery.
Three foundation base pictures, shown on following page, represent examples of alternatives to a concrete slab for
spas installed without gazebos or other accessories.

Page 3
*NOTE: A reinforced concrete pad at least four inches thick or
structurally sound deck able to support the “dead weight” found in the
spa specification chart for each model (see back page).The reinforcing
rod or mesh in the pad should be attached to a bond wire.
• Concrete sloped at 1/2 inch per 10 feet is preferred so that
rain water and water spillover will run off and not puddle
underneath the spa (water under the spa for long periods of
time may cause the wood to deteriorate).
• If stepping stones or railroad ties are selected for the spa
foundation, they should be placed and leveled below the entire
spa to maintain even distribution of the spa weight.
• It is important to note that soft surfaces, even when stepping
stones are used to distribute the weight of the spa as evenly
as possible, will still have a tendency to settle unevenly,
resulting in an unlevel spa.
• Remember, placing the spa on grass or dirt may increase the
amount of debris which is inadvertently brought into the spa
water on the user’s feet.
If you are purchasing a deck package or a spa enclosure with your spa,
a solid foundation becomes mandatory. Placing them on any surface other than a single level pad could create
problems with their installation. Pictured at right are a few of the recommended surfaces.
As a homeowner, it is your responsibility to provide a suitable, level foundation for your spa. Keep in mind that most
delivery crews are not equipped to level and prepare spa sites.
If you are interested in having a concrete slab, brick surface, or wood deck installed, your CALDERA dealer should
be able to suggest a qualified, licensed contractor.
DELIVERY ACCESS
First, locate the dimensions of your spa on the chart that is found on the next page. The dimensions shown are the
measurements of the spa in the vertical position, laid on its side.
Next, contact your dealer to find the height and width added by the delivery cart which the dealer will use to deliver
your new spa. Use the height of the cart plus the dimension shown as H to determine the vertical clearance required
to pass the spa and cart. Use the width of the cart, or dimension W, whichever is greater, to determine the maximum
width of clearance necessary. Use the length dimension L when making any sharp turns to determine the maximum
clearance required.
NOTE:It is strongly recommended to keep the spa in its original factory protective packaging particularly
when loading, moving or handling the spa in a vertical position. It may be necessary to allow for additional
over-head clearance if the spa will be rolled up or down an incline or moved up or down a short flight of stairs.
Use the information in the picture on next page to determine the requirements for access to your desired location.
It may be necessary to remove a gate, part of a fence, or other movable obstructions in order to roll the spa to
its installation site. About ten percent of the time, a crane is the only way to install the spa by lifting it to its final
destination.
If the spa has to be taken off of the cart to go over a wall (either because the entry area is too narrow, the eaves are
too low, the corner is too tight, or the stairway is too steep), a crane will be required. Don’t be alarmed!

The crane has a truck-mounted boom which can fit right in your
driveway. It is run by a licensed and insured
operator. For a charge, the crane operator will lift your spa over walls,
buildings, or any other obstruction and place it as close to the installation
site as possible. The CALDERA spa delivery personnel will supervise
the crane delivery and complete the spa installation.
If your spa delivery requires the use of a crane, you may be required to
pay for its services at the completion of the delivery

ELECTRICAL REQUIREMENTS
To ensure you will have an opportunity to use your spa soon after delivery, it is very important that the required
electrical service has been installed. Unless otherwise stipulated by your dealer, THIS IS YOUR RESPONSIBILITY.
IMPORTANT: All electrical circuits must be installed by a qualified, licensed electrician.
230 VOLT INSTALLATION
Your spa contains a control box designed to operate at 230V, 60Hz. Installation of a 50 amp. dedicated circuit is
recommended. The control box must be hard wired directly to a subpanel protected by a Ground Fault Circuit
Interrupter (GFCI). The subpanel containing GFCI breakers is included with the spa.
IMPORTANT NOTE:All electrical connections to the control box must be accomplished by a qualified electrician in
accordance with the National Electrical Code and in accordance with any local electrical codes in effect at the time
and place of installation.
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. A licensed electrician should install a four-wire electrical
service (two line voltages, one neutral, one ground) from the main electrical service panel to the subpanel. The
equipment pack requires a MINIMUM of 112 volts per line under load.
The grounding conductor must be at least #10 AWG. Your electrician should mount the subpanel in the vicinity of the
spa but it should not be closer than five (5) feet from the spa water edge (NEC 680-38 to 41-A-3).
INSTALLATION NOTE:After the spa has been installed, your electrician can connect the conduit from the subpanel
to the spa’s control box and then complete the wiring connections in the control box.
NOTE: Complete step-by-step Installation and wiring instructions for all models are included in the Owner’s Manual
and with each sub-panel, which can be obtained from your dealer.
WARNING: Removing or bypassing the GFCI breakers in the subpanel at any time will result in an unsafe spa and
will void the warranty.
230 VOLT CONVERTED CANTABRIA (OPTIONAL)
The CANTABRIA requires an additional 20 amp breaker in order to operate the heater at the same time as the
lounge pump #3.
This subpanel requires a 70 amp, single phase, 230 volt, four wire service (two line, one neutral, one ground). The
ground wire must never be less than #10 AWG. Use NEC 250-122 (table) and local codes for more information. A
minimum #6 AWG solid copper bond wire is also required.
NOTE: Complete step-by-step Installation and wiring instructions for the CANTABRIA are included in the Owner’s
Manual and with each sub-panel, which can be obtained from your dealer.
SEE ABOVE FOR IMPORTANT ELECTRICAL INSTALLATION NOTES.
