GLOSSARY OF SWIM SPA TERMINOLOGY
10. ACCESS PANELS
These are the skirt panels located around all four sides of the swim spa. All of the skirt panels
are removable should service be required. Master Spas recommends at least 3 feet of space
be provided around the swim spa.
11. EQUIPMENT ACCESS PANEL
This is the skirt panel located below the
Topside Control Panel or behind access
panel “A”. This area houses the majority
of components responsible for the swim
spa’s operation. These components
include the pumps, heater, swim spa
control system, ozonator (if equipped),
and LED light system (if equipped). Pump
and equipment placement may vary by
model.
12. FILTER LID
This lid fits over the filter area and weir gate to cover the filters. Remove filter lid to access
filters for maintenance. For models equipped with a telescoping filter housing, simply lift up
to remove this floating assembly to access the filter. At low speed water flow or when the
filtering/heating pump is off, the telescoping part of the filter assembly will float at or near
the waterline. At high speed water flow, it will be drawn downward. See Accessing Filters in
the Regular Maintenance Procedures section for detailed instructions on filter assemblies.
13. WEIR GATE
The weir gate is the horizontal door located in front of the filters that helps keep debris
trapped in the filter area.
14. SWIM SPA CONTROL SYSTEM
This houses the wiring and electrical components necessary to operate the swim spa.
15. SWIM SPA HEATER
This is an electric heater housed in a stainless steel tube. It is thermostatically controlled and
equipped with high-limit temperature safety shut-off sensors.
16. SLICE VALVES
These valves are used by service personnel to shut off water to the
heating system (heater and pump plumbed to the heater) so that
the swim spa water does not need to be drained if the swim spa
requires service to the heating system (varies by model).
NOTE:
Slice valves must be completely open during normal operations.
17. MAIN THERAPY PUMP
This produces water flow through the main jets in the swim spa. The first pump may be
operated on two speeds (varies by model). Low speed (if applicable) will produce efficient
water circulation during filtration, heating of the swim spa water, and gentle jet action. High
speed provides maximum jet action. The main pump is controlled by the “Jets” or “Jets 1”
button on the Topside Control Panel.
