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.
• 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.
• Note that on the Utopia and Aquatic Melodies®Series spas, the SpaGlo®exterior lighting fixtures are located on
only three sides, the side opposite the main control panel has no lighting.
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.
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)

Page 3
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 so long as a level base is
prepared prior to delivery. Three foundation base pictures, shown at
right, represent examples of alternatives to a concrete slab for spas
installed without gazebos or other accessories.
*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 is required for the Geneva™, Niagara®,
Elation®and Moorea™spas, and recommended for the Aspire®,
Tahitian®, Hawaiian, Martinique®and Kauai®spas. The reinforcing
rod or mesh in the pad should be attached to a bond wire.
INSTALLATION NOTES:
• 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.

NOTE: 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 below 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. Crane
delivery typically takes an average of 30 minutes to complete.
NOTE: 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.

POWER CONNECTION
To connect power to the spa, refer to “230 VOLT WIRING SCHEMATIC DIAGRAM” and “POWER
CONNECTION ACCESS” illustrations on page 11 , then proceed with the following steps:
When supplying power, remove the screws securing the equipment door (for Utopia and Aquatic Melodies®spas, always
remove the SpaGlo®exterior light fixtures and lift the fiber optic cable out of the fixture base before removing the doors).
Lower the panel one inch and remove the panel to allow access to the input power wiring.
NOTE: The 230V wiring diagram is located on the inside of the Control Box Cover.
IMPORTANT: The following must be followed to properly install the equipment compartment door.
• Place top of door or panel directly below bartop against the frame of the spa. For Utopia and Aquatic Melodies spas, first
lift the fiber optic cable out of the way.
• Push bottom of door or panel against the spa frame.
• Slide door or panel upward (pushing in on center of door to ensure door clips catch) until screw holes line up, making
sure that the exterior fiber optic light cable will fit into the fixture.
• Slightly pull on door or panel, if door remains against the spa then replace the screws.
• If the door does not lock into position, repeat the previous steps.
