4.3.5 Circulating pump (WPE 45 only)
Operation of a circulating pump can improve the temperature distribution inside the waterbath. The pump
draws water from the centre of the bath and distributes it through the pipes in the front and back of the
bath. The continuous water circulation avoids larger temperature differences. At a water temperature of
e.g. 90°C the temperature difference in the entire bath is less than 0.36°C.
Note:
If the boiling mode CCC has been activated, circulating pump operation is not possible!
Setting:
ON
or OFF
Rotate the push/turn control until the symbol flashes.
With the SET key depressed the circulating pump can then be switched on and
off.
