Ultrawave Qi Series Operator's Instruction Manual page 12

Screen 1: Setting the temperature
Your Qi-Series is fitted with a thermostat and heaters to ensure the
temperature of the cleaning fluid is maintained at the set temperature.
Use the UP and DOWN keys to accurately set the desired temperature of the
cleaning fluid between ambient and 80°C.
During normal use, the water heaters in your Qi-Series ultrasonic bath will
switch on if the cleaning fluid temperature is lower than the set temperature.
[As a safety feature, the heaters and ultrasonics in your Qi-Series ultrasonic
bath will only normally operate when the bath is full of fluid.]
Please note that during normal operation, ultrasonic energy will heat the
cleaning fluid by up to 15°C per hour.
Your Qi-Series ultrasonic bath cannot cool the cleaning fluid. If the fluid
temperature becomes too hot, you must either let it cool down, or refill the
bath with cooler water.
When the correct temperature is selected, use the MENU key to move to the
next screen.
SAFETY NOTICE: When the temperature is set to 54°C or
above, the case of the Qi-Series will become hot and care should be taken
when touching the case.
A risk assessment should be conducted – see BS EN ISO 13732-1:2008 for
full details.
When the desired temperature has been selected, use the MENU key to move
to the next screen.
