Definition 
Air Relief Valve 
 
Used for purging air from the filter system whenever servicing the 
filter, during initial startup, and whenever you drain and fill the 
Aquatic Fitness System
Air Volume Controls 
 
Increase or decrease the amount of air drawn through the jets.  The 
intensity of jet action is varied by adjusting the amount of air mixed 
with the water forced through the jets.  More air produces a more 
vigorous massage.  Since air bubbles tend to cool the Aquatic 
Fitness System
, the air controls should be closed while the 
Aquatic Fitness System is heating. 
Bleeder Valve 
 
A small valve used to relieve or expel air from the Aquatic Fitness 
System
’s plumbing or pump. 
Circulation Pump 
 
A pump that circulates the water in the Aquatic Fitness System 
continuously. 
Diverter Valve 
 
Allows you to select either the therapy jets or swim jets with pump 
number 1. Simply turn the valve to the desired position. 
Dry Firing 
 
Turning the heater element on when there is no water in the 
heater. 
Equipment Access Panel 
 
Provides access to your Aquatic Fitness System’s equipment for 
a qualified service technician.   
Equipment Control System
   
The electronic control system that governs all of the electrically 
operated components of your Aquatic Fitness System utilizes an 
advanced microprocessor and solid-state electronic switches to 
activate all user and maintenance options.   
Filter Cartridge 
 
Your Aquatic Fitness System’s filters have been designed so that 
you may repeatedly clean and maintain the filter cartridge as needed.  
The cartridge is constructed of woven polyester rather than paper 
to ensure long life and proper filtration. 
Filter Housing 
 
The filter canister that houses the filter cartridge. It encloses your 
Aquatic Fitness System’s cartridge filter element.  This filter 
cartridge removes dirt, oil and fine particles from your Aquatic 
Fitness System
’s water.  The lock ring holding the filter cover in 
place and the air relief valve in the filter cover must be on and 
closed when the Aquatic Fitness System is running.  DO NOT 
OVER-TIGHTEN THE LOCK RING OR THE AIR RELIEF VALVE. 
Also do not open filter housing while the Aquatic Fitness System 
is running as the filter is under pressure.

A type of Circuit Breaker that automatically disconnects power to 
the Aquatic Fitness System when there is an electrical power 
leakage to ground.
