CARE AND MAINTENANCE
16
Do not turn on the unit without water in the tank.
1
Even though the unit is designed with multiple protections, if
it is turned on for over 15 seconds without water in the tank, it
may damage the unit or severely reduce the life of the unit.
A thermal switch is attached to the bottom of the cleaning
tank. If the unit is turned on accidentally without water in
the tank, the ultrasonic energy will not be transferred out
through the liquid and instead will be concentrated on the tank,
the temperature of the tank will continue to rise. If the heater is
turned on at the same time, the temperature of the tank will rise
rapidly. This will trigger the thermal switch to cut off power to stop
2
the ultrasonic transducer and the heater from running, hence to
prevent damages to the unit and fire hazard. The switch cuts off
power for approximately 6-10 minutes then reconnect the power
automatically.
Do not run the unit for extended time or continuously.
The unit is designed with overheat protection. If the unit has
been running for 45 minutes, it is recommended to stop the
unit for about 20 minutes to prolong the life of the unit.
3
Do not keep chemicals in the cleaning tank overnight or
when it looks dirty.
After cleaning is completed, open the drainage valve to drain
the dirty water. Clean and wipe the tank dry.
4
Do not spray water over the housing.
Use a towel to wipe the tank and the housing dry.
5
Do not expose the unit under direct sunshine for a long
time.
Keep the unit in a dry, cool and ventilated area.
Keep the original packing material in case of sending it for
repair service. If it is no longer available, use enough cushioning
equivalent to minimum 1" Styrofoam all around the unit inside the
shipping carton to avoid damages to fragile transducers. Warranty
doesn't cover damages during shipping.
