Installing Plumbed Shells:
Above Ground Installation
(Timber Surround)
Prepare the foundation by excavating to the size required. Either lay the base first and let it cure, or sit the Spa
pool into the wet foundation. The Spa pool must be levelled before the concrete sets. If you choose to have
the base cure first, the Spa pool will have to be set into a weak sand and cement mix for leveling purposes
(as shown in Diagram B).
After the Spa pool has been levelled and the base has set, the surround structure can proceed. The Spa pool
return rim should be clear of the pool surround; no weight is to be taken by the rim.
Fill the bottom of the Spa
pool with water to cover all plumbing outlets and check for water leaks
; rectify if necessary. Empty water
after check is made.
The seat and reclining area must be supported by a 10:1 sand and cement mix, constantly check the Spa pool
for level when backfilling and check the sand mixture is packed firmly under both areas. The Spa pool can be
further insulated by applying thermal insulating material between the Spa pool wall, and the surround structure
where practicable.
