Electrical Requirements

THIS INSTRUMENT MUST BE GROUNDED

Before connection please ensure that the line supply corresponds to the power requirements below:
RE400DB 1400 W 230 V a.c. ~ 50/60 Hz
RE400OB 1400 W 230 V a.c. ~ 50/60 Hz

The unit is supplied with two mains leads fitted with IEC plugs for connection to the instrument. One lead has a UK
3 pin plug and the other has a 2 pin “Schuko” plug for connection to the mains supply. Choose the lead appropriate
for your electrical installation and discard the other. Should neither lead be suitable take the lead with the UK plug
and replace the plug with a suitable alternative. This involves cutting off the moulded plug, preparing the cable and
connecting to the rewireable plug in accordance with its instructions.

THIS OPERATION SHOULD ONLY BE UNDERTAKEN BY A QUALIFIED ELECTRICIAN.

3
 NOTE: Refer to the equipment rating plate to ensure that the plug and fusing are suitable for the voltage and
wattage stated. The wires in the mains cable are as follows:

BROWN - HOT/LIVE
BLUE - NEUTRAL
GREEN/YELLOW – EARTH

The appropriate mains lead should be connected to the instrument BEFORE connection to the mains supply.
Should the mains lead require replacement, a cable of 1.25mm² (AWG16) of harmonised code H05VV-F
connected to an IEC320 plug should be used.

IF IN DOUBT CONSULT A QUALIFIED ELECTRICIAN

Before Use
Place the Rotary Evaporator Bath on a firm, level surface.

Caution: The Bath may be HOT. As a precaution for the user, take care when handling.
NOTE: If the unit has been used recently the bath may be too hot for your sample. If this is the case,
press the stop button and allow the unit to cool before proceeding.

RE400DB

The RE400DB is intended for use with water only.

WARNING: DO NOT use the RE400DB with any liquid other than water.
May cause fire on failure.

Fill the Teflon coated bowl to the required level with cold water. To avoid scale build up and the necessity for
cleaning it is recommended that the bowl be filled with distilled or deionised water.

The maximum capacity of the bath is 3 litres and it should not be filled to within less than 2cm from the top of the
bowl.

During use water will be lost from the bath by evaporation. For maximum efficiency water should be added
periodically and the level maintained.

RE400OB

The RE400OB is intended for use with either oil or water.

WARNING: Oil and water should never be mixed in the bath.

Water will evaporate in an explosive manner if it mixes with oil at a temperature of more than 100°C.

Fill the Teflon coated bowl to the required level with either oil or water.

The maximum capacity of the bath is 3 litres and it should not be filled to within less than 2cm from the top of the
bowl.

If being used with water, during use water will be lost from the bath by evaporation. For maximum efficiency
water should be added periodically and the level maintained.
