Preparing A Good Foundation; 240 Volt Electrical Installation - Cal Spas F-1222 Owner's Manual

Preparing a Good Foundation

Your spa needs a solid and level foundation. The
area that it sits on must be able to support the
weight of the spa, with water and the occupants
who use it. If the foundation is inadequate, it may
shift or settle after the spa is in place, causing stress
that could DAMAGE YOUR SPA SHELL AND FINISH.
Damage caused by inadequate or improper
foundation support is not covered by the
warranty. It is the responsibility of the
spa owner to provide a proper foundation
for the spa.
Place the spa on an elevated 3 to 4" / 30 cm concrete
slab. Pavers, gravel, brick, sand, timbers or dirt
foundations are not adequate to support the spa.
We strongly recommend that a qualified, licensed
contractor prepare the foundation for your spa.
If you are installing the spa indoors, pay close
attention to the flooring beneath it. Choose flooring
that will not be damaged or stained.
If you are installing your spa on an elevated wood
deck or other structure, it is highly recommended
that you consult a structural engineer or contractor
to ensure the structure will support the weight of

240 Volt Electrical Installation

All 240V spas must be permanently connected (hard
wired) to the power supply. See the GFCI and wiring
requirements on page 5.
These instructions describe the only acceptable
electrical wiring procedure . Spas wired in any
other way will void your warranty and may
result in serious injury .
When installed in the United States, the electrical
wiring of this spa must meet the requirements of NEC
70 and any applicable local, state, and federal codes.
The electrical circuit must be installed by an
electrical contractor and approved by a local
building or electrical inspector .

150 pounds per square foot (732 kg / m2).
To properly identify the weight of your new spa when
full, remember water weighs 8.33 lbs. per gallon, or
1 kg per liter. For example, an average 8' spa holds
approximately 500 gallons, or 1892 liters, of water.
Using this formula, you will find that the weight of the
water alone is 4,165 lbs, or 1892 kg. Combined with
the dry weight of the spa you will note that this spa
will weigh approximately 5,000 lbs, or 2267 kg, when
full of water.
may result in fire or personal injury and will be
the sole responsibility of the spa owner .
The power supplied to the spa must be on a dedicated
GFCI protected circuit as required by NEC 70 with no
other appliances or lights sharing the power.
Use copper wire with THHN insulation. Do not use
aluminum wire.
Use the table below and on the next page to determine
your GFCI and wiring requirements.
Wires that run over 100 feet must increase wire gauge
to the next lower number. For example: A normal 50
amp GFCI with four #6 AWG copper wires that run
over 100 feet would require you to go to four #4 AWG
copper wires.
