*NOTE:
Have a reinforced concrete pad at least 4 inches (10cm) thick
or a deck that is able to withstand the pounds per square foot listed in
the Spa Specification section. The reinforcing rod or mesh in the pad
should be attached to a bond wire.
•
Concrete sloped at 1/2 inch per 10 feet (1 cm per 3 m) 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 brick or wood decking is selected for the spa foundation, it
should be placed and leveled below the entire spa to maintain
even distribution of the spa weight.
•
It is important to note that if bricks are used to distribute
the weight of the spa there may still be a tendency to settle
unevenly, resulting in an unlevel spa.
•
Remember, placing the spa around 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. Shimming or point leveling is NOT supported or
recommended by the manufacturer.
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 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!
