7 Adjustable Water Level Regulator (Accessory Order-No. A000024)
The adjustable water regulator at the back of the Water Bath serves to level out the loss of water due to evaporation during
operation, thus maintaining the set water level. Furthermore, the adjustable water regulator allows the Water Bath to be
operated at temperatures below ambient, with a minimum of approx. 3 K above tap water temperature.
Before initiation, the water regulator must be connected to the water mains. The upper hose connection of the water
regulator is the water supply. Using a laboratory hose with an inner diameter of max 9 mm, connect this to the water
mains. The lower hose connection is the overflow of the water regulator. Connect a laboratory hose (inner diameter of max
9 mm) and lead it into a drain on a lower level, ensuring free flow of the water without it being banked up.
Secure all hose connections with hose clips.
The required water level can be adjusted with the outlet tube of the
water regulator. First loosen the screw connection of the outlet tube,
using a spanner GW 27. Set the required water level by pulling out or
pushing in the tube in the regulator. Then retighten the screw con-
nection. Now open the tap of the mains supply slightly and fill water
into the Water Bath, as described in chapter 6.
8 Functional Description and Initiation
The electronic regulator controls the water temperature of the Water Bath. Three timer functions
permit switch-on delay as well as setting the duration of the operation time. A high-contrast 3.5"
TFT display shows all set points and operational values. These can be controlled with four mem-
brane keys, situated to the right of the display. The controller is equipped with an electronic moni-
toring function with visual and acoustic alarms in case of a malfunction. Additionally, the Water
Bath is protected from overheating through running dry by a low water cut-off that is also moni-
tored by the function control of the regulator. After switching on the main switch of the Water
Bath, the green pilot lamp in the switch will light up. The display first shows the startup screen, and
then the main menu. The four membrane keys to the right of the display allow access to all menu
functions, setting and confirming process values.
