Caldera Highland Series - Manual (Page 5)

SITE SELECTION
Because of the combined weight of the spa, water and
users, it is extremely important that the base upon which
the spa rests is capable of uniformly supporting this
weight, without shifting settling, for the entire time the spa
is in place. If the spa is placed on a base which does not
meet this requirement, damage to the cabinet and/or the
spa shell may result. Damage caused by improper sup-
port is not covered under warranty. It is the spa owner’s
responsibility to ensure the integrity of the spa’s support
over time.
We recommend a poured, reinforced concrete slab for
the spa’s base. Wood decking, pre-cast concrete slabs,
concrete blocks or other materials may also be suitable if
they meet the requirements outlined above. Wood deck-
ing must be constructed to support at least eighty pounds
per square foot. Consult with a qualified contractor or
engineer if you are in doubt.
Your spa must be installed so as to provide drainage
away from the spa. Placing the spa in a depression with-
out provisions for proper drainage could allow rain, over-
flow and other casual water to flood the equipment and/or
create a wet condition in which the spa would sit.
When considering an installation site, allow a minimum of
thirty inches for access to the spa’s equipment compart-
ment for future service if necessary. If accessory items
will be installed on or around the spa (Spa CoverGlide,
gazebo, steps or planters), allow for additional space
around the spa’s perimeter.
Please note that some cities and counties may require a
permit for installation of electrical circuits or the construc-
tion of exterior structures (decks and gazebos). In addi-
tion, some counties may require permits for the installation
of a portable spa. Check your local codes for compliance.
To ensure you can use your spa soon after delivery, it is
important that you select the voltage prior to setting your
spa in place and have a licensed electrician install the
wiring, if necessary.
SELECTING THE VOLTAGE FOR YOUR SPA
Your spa is designed to operate at either 120 or 220 volts,
60 Hz unless it is the Olympia model which requires 220
volt power supply. When the spa is connected to 120
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. When the spa is con-
nected to 220 volts, the heater will provide approximately
4000 watts of heat when the pump is operating in LOW or
HIGH speed and the thermostat is calling for heat.
All electrical connections must be made in accordance
with the wiring information contained in this manual, in
the electrical control box or on the back of the field wiring
access panel of the equipment module.
120 VOLT INSTALLATION
Spas provided with a factory- installed power supply cord
are to be plugged into a grounded, grounding type, 120
volt, 15 ampere receptacle (Sierra, Teton models) or 20
ampere receptacle (Cascade model). No other electrical
appliance or fixture can be used on this circuit.
IMPORTANT: Under NO circumstances should an exten-
sion cord be used. Use of an extension cord will seriously
degrade the performance of the equipment module and
can create an electrical hazard.
220 VOLT INSTALLATION
When using 220 volt power supply, installation of a 40
amp dedicated circuit is required. Your spa must be hard-
wired direct to a GFCI-protected power source by a
licensed electrician. A wiring diagram is provided inside
the equipment module showing where the connections
are to be made.
