Ozone humming is normal. It is the vibration of ozone being sucked through the Mazzi Injector.
If winterizing the hot tub: follow detailed steps in Owner’s Manual or contact our store for assistance. Damage caused to your spa by improper winterizing is NOT covered by your spas’ warranty. New England Spas offers a Winterizing and Un-Winterizing service. As the months get colder NES may not be able to complete this service. We recommend you consider and schedule a call prior to November 30th.
To minimize airlocks in the equipment follow these steps below and turn hose on. This will fill the tub through the heater, pumps, and jets pushing most of the air out of the lines.
If the hot tub has no power, or is not heating:
Hot Spring Spas: Place a droplight with a 60 or 75-watt bulb inside the access panel over pump one. (Facing control panel, usually behind right wooden section)
Sundance Spas: Place a small, UL listed, space heater into the main equipment area on LOW HEAT, HIGH FAN.
In both cases, make sure neither the drop light or space heater is not touching any components, wires, or insulation and replace the cabinet panel to the best of your ability. Leave the hot tub cover on and fastened to retain as much heat as possible.
Shut off the power to the hot tub at the outside breaker for about 45 minutes. Turn the power back on and check the system. Sometimes this “reboot” procedure clears up the problem.
