GLOSSARY OF SPA TERMINOLOGY
14. Spa heaTeR
This element is an electric heater housed in a stainless steel tube. It is thermostatically controlled
and equipped with a high-limit temperature safety shut-off sensor. The high-limit sensor cannot
be reset until the temperature within the heater assembly drops several degrees below the shut-off
temperature of 108° - 110° F (varies by model). Should the high-limit switch trip repeatedly,
contact your dealer or qualified service representative to diagnose the problem.
15. SLIce vaLveS
These valves are used by service personnel to shut off water to the
heater, main pump system and secondary pump system so that the
