GLOSSARY OF SPA TERMINOLOGY
14. WEIR GATE
The weir gate is the horizontal door located in front of the filters that trap debris in the filter
area
15. EQUIPMENT CONTROL SYSTEM
This houses the wiring and electrical components necessary to operate the spa.
16. SPA HEATER
This element is an electric heater housed in a stainless steel tube. It is thermostatically con-
trolled and equipped with a high-limit temperature safety shut-off sensor. The high-limit sen-
sor 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.
17. 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 water does not need to be drained should the spa
require service (varies by model).
NOTE:
Slice valves must be completely open during normal operations.
Slice Valve and Pump Union
18. MAIN PUMP
This produces water flow through the main jets in the spa. The first pump may be operated
on two speeds. Low speed will produce efficient water circulation during filtration and gentle
jet action. High speed should be used for maximum jet action. The main pump is controlled
by the “Jets” or “Jets I” button on the Topside Control Panel.
