Emergency Shut-Off Switch (ESO3)
Emergency Shut-Off switch
The SunTouch system can be used for commercial spa applications that require an Emergency Shut-Off
(ESO3) switch. It can be installed with new or existing pool and spa system. In the event of an emergency, the
spa can be shut off by pushing the red emergency button. This action interrupts power to the filter pump, jet
pump, an optional auxiliary pump, air blower, or equipment connected to AUX 1, or AUX 2. Pulling the
emergency button back out will return the pumps to normal operation, and shut off the alarm.
Location
Select a convenient location to mount the Emergency Shut-Off switch. Provide a double-gang electrical box.
The electrical box must be rated for outdoor use if the Emergency Shut-Off is located outside. Provide and
install a standard spring-wound timer for the jet pump and filter pump. Install cable, using plastic or metallic
conduit where cables run underground.
