Page 6: Material Quality
2.1 Material quality Memmert is using stainless steel ( Mat.Ref. 1.4301) for the external casing as well as for the interior, an outstanding material because of its high stability, optimum hygienic features and corrosion resistance against many (not all!) chemical combinations (Attention e.g. at chlorine combinations!). -

2.5 Standard equipment • Electronic fuzzy-supported PID process controller with delayed programme start and programmable hold time. The controller has permanent power matchinig and an autodiagnostic system for rapid fault finding • Recessing push/turn control for simple operation of bath •... -
Page 8: Initial Start-Up
3.1 Initial start-up When the bath is started up for the first time, it should be supervised continuously until steady conditions have been reached. 3.2 Installation - waterbaths Mains The mains connection cable must be placed away from any hot surface. connection Filling max water level... -
Page 9: Installation - Oilbaths
3.3 Installation - oilbaths Mains The mains connection cable must be placed away from any hot surface. connection Filling max water level min water level drain valve IMPORTANT! The liquid level in the bath must be between the two markings at the right side of the tub! The spacing between top edge of oilbath and liquid level must be at least 30 mm as the oil expands strongly on heating. -
Page 10: Bath Construction And Operation
4 Bath construction and operation relatively largest heat loss (since minimum heat loss (since furthest away from the heated ribs) very close to the heated ribs) bath Insulation heating elements The heating positioned on three sides around the tank ensures a natural water circulation of the liquid inside, thus securing an optimal uniform temperature distribution. -
Page 11: Switching On
4.2 Switching on The bath is switched on by pressing the push/turn control and can be operated in connection with the SET-key. Bath switched off: The push/turn control is pushed in and protected against damage. 4.3 Setting the parameters A parameter can be selected by rotating the push/turn control; all other parameters are then dimmed. The selected parameter flashes brightly and can now be altered with the push/turn control while holding down the SET key (protection against unintentional alteration). -
Page 12: Temperature Setpoint
4.3.1 Temperature setpoint Adjustment range: waterbaths: 10°C to 95°C or ca. 100°C with 90°C activation of the boiling mode oilbaths: 10°C to 200°C Setting and indication accuracy: The bath starts to heat up immediately water-/oilbaths: 0.1°C to the set temperature. Rotate the push/turn control until the symbol flashes. -
Page 13: Hold Time Of The Setpoint Temperature
4.3.3 Hold time of the setpoint temperature Adjustment range: 1 min bis 999 hrs 90°C Setting accuracy: <100 hrs: 1 min hold 6h ≥100 hrs: 1 hr The bath switches off the heating after Indication accuracy: the end of the selected hold time. In this <10 hrs: 1 min case the hold time includes the heating- ≥10 hrs: 1 hr... -
Page 14: Circulating Pump (Wpe 45 Only)
4.3.5 Circulating pump (WPE 45 only) apertures to circulating pump pipe circulating pump waterbath WPE 45 (view from above) 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. -
Page 15: Temperature Monitor
4.3.6 Temperature monitor Adjustment range: monitor temperature up to 10°C above nominal temperature setpoint temperature Setting and indication accuracy: <100°C: 0.1°C ≥100°C: 1°C (see also sections 4.3.8.2 and 7) Rotate the push/turn control until the monitor temperature display flashes. °C The monitor temperature can then be adjusted with the SET key depressed, as described in section 4.3. -
Page 16: Calibration
4.3.8.1 Calibration Customer calibration of the bath on the controller using a self-selected calibration temperature. A positive or negative calibration difference against it can be set. General calibration instructions: Set the required calibration temperature and set the calibration difference to 0.0°C (see below “set calibration temperature“... -

4.3.8.2 Selection of temperature monitor (waterbaths only) Class 2 Class 3.1 Setting: monitor temperature monitor temperature 2 or 3.1 setpoint temperature setpoint temperature Rotate the push/turn control until flashes. °C With the SET key depressed it is possibile to select the temperature monitor as adjustable temperature limiter (TWB) Protection Class 2 to DIN 12880, or as adjustable temperature monitor (TWW) Protection Class 3.1 (see also sections °C... -
Page 18: Monitoring The Programme Sequence
6 Monitoring the programme sequence During the delayed switch-on the symbol 90°C °C flashes and the display alternates between residual time and actual temperature delay 6h hold 4h °C Bath does not heat up SP activated: 90°C °C After the end of the delayed switch-on the symbol goes dark and the bath heats up to the selected setpoint temperature. -
Page 19: Temperature Monitor And Protection Devices
7 Temperature monitor and protection devices The monitor temperature is measured with a separate Pt100 temperature sensor inside the chamber. The monitor unit provides protection for the bath load as well as protection for bath and its surroundings. The bath is provided with duplicate overtemperature protection (mechanical / electronic) according to DIN 12880. -
Page 20: Adjustable Temperature Monitor (Tww) Protection Class 3.1 To Din 12880
7.2.1 Adjustable temperature monitor ( TWW) Protection Class 3.1 to DIN 12880 If the manually set monitor temperatur is exceeded, the TWW takes over the control of the temperature and starts to control at the monitor temperature. The symbol flashes as warning. 7.2.2 Adjustable temperature limiter ( TWB) Protection Class 2 to DIN 12880 If the manually set monitor temperature is exceeded, the TWB switches off the heating permanently and can only be reset by pressing the SET key. -
Page 21: Use Of The Cover (Special Equipment)
8 Use of the cover (special equipment) Gable cover The gable cover (may be ordered as already mounted special equipment) should always be closed in order to prevent evaporation of thermostating liquid and to obtain optimal temperature distribution. The gable shape of the cover makes sure that condensed water will not drop down into the loads. -
Page 22: Cooling System (Special Equipment)
10 Cooling system (special equipment) If the waterbath is fitted with a cooling device water supply for quicker cooling of the bath liquid, the “water supply“ has to be connected by a hose f.ex. to a cold water supply line. The “discharge“ has to be lead into a drain. -
