OUTDOOR AND PATIO INSTALLATION
To install the spa outdoors, we recommend a reinforced concrete pad at
least four inches thick. The reinforcing material should be attached to a #8
AWG bonding wire per national and local electrical code.
If you place the spa on the ground, even temporarily, place the spa empty of
water on concrete pavers under the entire bottom of the spa. The concrete
pavers should be a least two inches thick and level across the entire sur-
face. The spa will inevitably settle and not remain level on this surface, thus
it's important to get the spa onto a solid foundation as soon as possible.
INSTRUCTIONS FOR PREFABRICATED SPA PADS
If you are using a prefabricated spa pad for a foundation, please use the fol-
lowing guidelines:
1. Designate the area where the spa is to be installed. Please make sure
the ground is flat and level.
2. Using 2"x 6" (51mm - 152mm) weather resistant lumber and 3" (76mm)
outdoor deck screws, build a frame large enough for the prefabricated
spa pad to fit inside with minimum 1" (25mm) clearance on all sides.
3. Install the frame in the area that has been leveled.
4. Using crushed gravel, fill the frame to the top.
5. Lay a straight piece of lumber across the frame and level any high spots
in the gravel by pushing the straight lumber across the frame. Fill in any
low areas with more gravel and re-level using the straight piece of lumber.
6. Compact the gravel to make the surface hard and flat. You may need to
add more gravel to bring the level back up to the top of the frame. If so,
please re-level and re-compact until you have a hard, flat level surface
that is even with the top of the frame.
7. Place the prefabricated spa pad on top of the gravel. Please be careful
not to disturb the hard, flat, level surface.
8. Please make sure no portion of the spa pad is sitting outside or on top
of the framing.
9. Place the spa on top of the pad and fill the spa with water.
DECK INSTALLATION
Be sure the deck can support the weight of your filled spa by checking the
deck's maximum load capacity. Consult a qualified building contractor or
structural engineer. Minimum requirement is 100 lbs. (45 kg) per square
foot.
INDOOR INSTALLATION
There are special requirements if you place your spa indoors. Flooring mate-
rial must provide adequate traction when wet. Proper drainage is essential
to prevent water puddling. Proper ventilation to the area is required. The
addition of a ventilation system is recommended. Please see your contractor
for details.
