Definition
Heater
An 11kw 230v thermostatically controlled electric heater equipped 
with a high-limit temperature safety shut-off switch. If the high-limit 
safety switch trips, contact your authorized Aquatic Fitness 
System Dealer. See the 
information.
Jets
Return the water into the Aquatic Fitness System from the 
equipment. The HydroTherapy Jets produce a turbulent flow of 
water mixed with air to provide a concentrated body massage. The 
Swim Jets produce a high volume flow to provide a rapid current for 
swimming. 
Light
Illuminates the Aquatic Fitness System vessel.
Load Sharing
When the circuit breaker size is smaller than the total power 
needed to operate both the heater and the jet pump at the same 
time, load sharing automatically turns off the heater when a jet 
pump is turned onto high speed. 
Lock-Ring
Mechanism that affixes filter cover to filter housing. To remove 
cover, turn lock-ring counter-clockwise until it disengages with filter 
housing. When replacing the filter cover, turn lock-wring clockwise 
to firmly secure the cover. 
Ozone Generator
A specialized ultraviolet light that changes oxygen into ozone for use 
in the water sanitation process. 
Pressure Switch
Safety device(s) that sends a signal to the electronic control system 
that there is adequate water flow to turn the heater on. 
Primary Pump
Produces water flow through the heater, filter, sanitation system 
and the main jets in the Aquatic Fitness System. The primary 
pump will operate automatically during filtration and heat cycles. 
This pump can also be operated manually by depressing the “jets” 
button on the Top Side Control which will allow you to choose 
between two speeds 
• Low speed for efficient water circulation during heating and
filtration modes, and for gentle jet resistance or massage 
action. 
• High speed for maximum jet action.
Pump Union
A removable fitting that connects the pump to the Aquatic Fitness 
System’s plumbing. 
Selector Valve
Located on the top edge of the Aquatic Fitness System or spa, it 
diverts jet power from one area of the Aquatic Fitness System 
or spa to another. 
Serial Number
Please use the serial number in communication with your dealer.
Servicing Filter Element
To clean or replace the filter element, shut off power to the 
Aquatic Fitness System, loosen the lock-ring, remove the filter 
cover and pull the filter element from the filter housing. Depending 
upon use, you may simply rinse the filter element with a garden 
hose, or you may be required to soak the element in Filter Cleaner 
Solution. Replace any worn or damaged filter elements. It is always 
good practice to have a spare filter element, so that you can 
perform cleaning at your convenience.
