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. SPA LIGHT
Your spa light is designed for safety and is located in the interior wall of your spa. The on/off
switch is located on the topside control panel.
16. EQUIPMENT CONTROL SYSTEM
This houses the wiring and electrical components necessary to operate the spa.
17. 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.
18. 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.
NOTE:
Legend Series spas are the only models that come with slice valves on all pumps.

19. 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 or by using the Personal Remote Control
next to the Aqua Pressure Seat (Legend Series only).
