Operating Manual
Check that the unit is plugged in and that mains electricity is
present.
Fill the Grant digital ultrasonic bath with water so that it is above
the fill line indicated inside the tank.
If you are using "pure" water (e.g. De-I or RO) ensure that the
detergent has been added.
The Grant digital ultrasonic bath is fitted with an ultrasonic power
detector, which monitors the ultrasonic activity in the bath during
a cleaning cycle.
If the ultrasonic power drops below a certain point, the cycle will
be incomplete and this message will display. This is not
necessarily caused by a problem with the machine.
If this message displays, run another cycle to see if the problem
persists.
The Grant digital ultrasonic bath has detected that the heaters
operated above their rated temperature and has disabled the
heating function. This also disables a cycle from starting. The
most likely cause is the liquid evaporating when the level sensor
is switched off.
Switch the unit off, top up the fluid above the level sensor and
switch the unit on to reset the alarm.
The Grant digital ultrasonic bath has detected that the ultrasonic
generator on the unit has operated above the rated temperature
and has disabled the ultrasonic function. This also disables a
cycle from starting. The most likely cause is the fluid evaporating
when the level sensor is switched off. Switch the unit off, allow
the unit to cool for a few minutes, top up the liquid above the
level sensor and switch the unit on to reset the alarm.
The Grant digital ultrasonic bath has detected that the water in
the bath is above 75ºC and has aborted the cycle. Please allow
the liquid to cool or drain some and replace with cooler liquid.
