TM 330 or Super Aquatene TM 360 solution to the base
reservoir tank.

9. Plug power cord into properly grounded 115V, 15 amp circuit. Full load amp-draw of unit
is 12 amps.
10. Press TEST button on GFCI on rear of control (right) to ensure switch is operating
properly. Press RESET button on GFCI to prepare unit for operation.
11. Air pump will begin operation immediately upon power being applied to the machine and
the red “RESET” light will illuminate.
12. Toggle RESET switch located under the electrical box to begin operation. If the unit has
an adequate level of cleaning solution in the tank, the green “READY” light will illuminate
and the red “RESET” light will extinguish.
13. The amber “HEAT” light indicates power to the heater.
14. If cleaning solution is not at the appropriate temperature and heat is required you should
hear the thermostat engage with a “CLICK” and the amber “HEAT” light will illuminate.
Should this not happen, press the red thermostat reset button on the rear of the control
box (right). Should this problem persist: unplug machine and call factory.
15. When the unit reaches its predetermined temperature, the “HEAT” light will extinguish,
indicating the cleaning solution is at the proper temperature to obtain maximum cleaning
efficiency. For maximum cleaning efficiency, allow heater to warm solution for 2 to 4
hours before use.

19. Failure to keep proper liquid level will result in burning out the pump and heater coil, creating a potential fire hazard. To
prevent this, this unit is equipped with a low liquid level device which will shut off the pump and heater. If solution stops circulating
and the red “RESET” light becomes illuminated, immediately turn off and unplug unit. Follow steps 6 through 8 above for
instructions on refilling unit.
20. When finished, turn pump off and close lid to minimize liquid loss due to evaporation (DH436R only).
