5. Operation
5.1 General
Connect to the electricity supply – DO NOT
SWITCH ON. Place the unit on a firm level non-
slip surface and
fill the bath with the required level of water,
ensuring that the level sensor is below the water
level.
NB It is advisable to fill the bath with
demineralised water to prevent the
formation of scale.
5.2 Loading the platform
Arrange the vessels on the platform outside the
bath. Position the retaining springs where
required to secure the load. When the load is
secured place the platform inside the bath.
NB For safety, Do NOT remove the platform
from the bath when the water is hot.

desired setting is obtained.
The speed can be adjusted without halting the

The shaking water bath will now automatically
heat up to the set temperature.
5.5 Low level water sensor
The low-level water sensor is designed to provide
a warning when the water level has become too
low in order to protect the bath from
overheating. The sensor is located towards the
bottom of the tank on the sidewall (see figure
2). When the water level drops below the
sensor, the LED display will flash 'H20' and 'ERR'
to indicate that the water level is too low and
the heater will switch off. The heater may be
restarted by filling the bath with water to the
required level above that of the sensor.
NB The lens of the sensor must be wiped
clean with a damp cloth at regular intervals
to ensure correct function.
