Gravel
Use ONLY ½ net gravel for levelling the bottom and backfilling around the spa. In general, 8 to 12 tons of
gravel will be required to complete these steps. Refer to your dealer for details on approximate amounts
of gravel as these may vary depending on the spa model and the digging method.
8
Preparing
the bottom
Spread a geotextile-type canvas over the entire hole. 8
Lay about 3" to 6" of gravel evenly over the bottom of the hole and over the geotextile fabric. 8
Reserve the rest of the gravel for backfilling the spa. 8
Levelling
Level the gravel at the bottom of the spa according to the digging plan. 8
Drainage
Vertically and immediately adjacent to the fibreglass spa, install a pipe about 6" in diameter that will serve
as a decompression well (also called SIGHT HOLE or DE-WATERING WELL). 9
This pipe should be about 6" deeper than the spa. It must be installed from the edge of the spa and up to
approximately 6'' deeper than it. It will be held in place by the gravel during backfilling.

While the backfilling is in progress, make connections (screw connections) to the technical box containing the
motor system. 14

regarding heat pumps with respect to the distance from
the lot boundaries and the number of decibels.

You must also plan the location of your spa taking into
account the following:
• The sunshine in the yard
•The location of the patio and shed
• Children's play area
• Overhead or underground electrical wires
