If you are planning to bury the plumbing pipes and conduit for your spa, dig the trench deep enough
to make sure the pipes are beneath the frost line (the depth at which the moisture in the earth
freezes and thaws). This frost line can vary, depending on the area you live in. This is more important
if you live in a colder climate.
This trench must be wide enough to hold all plumbing pipes and the electrical conduit. You can
insulate the pipes with foam insulation if you desire.
NOTE: Do not backfill the trench until after the spa has been water tested and inspected.
Installing the Conduit
Lay a 2-inch diameter PVC conduit from the equipment pack to the spa. This conduit must be
waterproof to keep moisture away from the electrical wires.
NOTE: Use PVC sweeps for bends in the conduit instead of 90-degree elbow. Elbow can make it
difficult to pull the wires though the conduit.
Installing Your Spa
Once you have finished preparing the site, it is time to install your spa. This will include making all
connections between the spa, equipment pack, and residence.
1. Using a crane or boom truck, insert the spa into the vault. The use of spreader bars is advised
to protect the spa top lip and edge. Your crane operator should be able to provide these.
