OPERATING INSTRUCTIONS
When entering an Universal walk-in tub, be sure to close the door, placing the 
handle in the down position. Before activating any of the jetting controls, you 
must first fill the bath to a water level at least 2 inches above the highest jet 
placement. Do not put weight on the door when entering and exiting the tub. 
It is recommended to leave the door in the open position when the tub is not 
in use.
The pump is operated by the hydro control button, which starts the water flow. 
The blower is operated by the air control button which starts the air flow (see 
page 18).
Adjust the direction and rate of flow of the jets by moving the nozzle for direction. Turn either the outside ring or the nozzle clockwise 
or counterclockwise for flow (some jets adjust the flow with the outside ring and some with the nozzle). Adjust the air pressure flow 
of all water jets by using the air volume control (see page 18), which controls air-water mixture.
Universal walk-in tubs equipped with the chromotherapy lights (ordered separately), feature a dedicated on/off switch. Pressing the 
switch off and back on will change the color of light (see page 18).
PURGE CYCLE
All air blowers are equipped with a purge cycle to remove residual water from the lines. The cycle will begin approximately 30 
minutes after the unit is turned off and will continue for 1 - 2 minutes.
WARNING: DO NOT PUSH THE BUTTON ONCE THE CYCLE BEGINS. DOING SO WILL CAUSE 
EXAMPLE TUB DOOR HANDLE
