1. Safety
1.1 Warning symbols
The symbols below are marked on the equipment to indicate:
Caution: Surfaces and water can be hot during and after use.
Read this manual before using the bath
1.2 Safety certification
VWR water baths meet the requirements of international safety standard IEC 61010-2-10 and
IEC 61010-2-51 and national standards based on them including:
UL 61010A-2-010
UL 61010-2-051-04
CAN/CSA-C22.2 NO. 61010-2-010-04;
CAN/CSA-C22.2 No. 61010-2-051
1.3 Safety features
The shaking trolley is driven by a magnetic drive system. The drive magnet in the tank is
magnetically coupled to a motor-driven magnet under the tank. The magnetic coupling
cannot exert enough force to cause injury.
To protect samples in case of failure of the primary temperature control system there is a
second completely independent user-settable control system.
In addition to the second control system for sample protection, there is a separate fixed-
temperature cut-out to protect the bath and surroundings in the very unlikely event of failure
of both control systems.
1.4 Before first operating the equipment
Read the whole of these instructions. Safety may be impaired if they are not followed.
If the equipment has been transported or stored in cold or humid conditions, condensation
may form inside it. If that could have happened, allow time (at least 2 hours) for the
condensation to evaporate before using the equipment.
1.5 Precautions during and after operation
The bath is for use only with water as the bath liquid. Make sure that it cannot become
contaminated by other liquids. The use of de-ionized water is recommended to prevent
corrosion. A full explanation of this is given in Section 6 of this manual.
CAUTION. PLEASE FILL BATH WITH WATER BEFORE SWITCHING ON.
Change the water regularly and empty when not in use for prolonged periods, to further
prevent corrosion and contamination.
Before emptying a bath, allow the water temperature to fall to a safe level. The 18 litre bath,
should be emptied moving.
Do not use the equipment in an area where there are aggressive or explosive chemical
mixtures or atmosphere.
If potentially hazardous liquid is spilt onto the equipment, disconnect it from the power supply
and have it checked by a qualified service technician. It is the user's responsibility to carry
out appropriate decontamination if hazardous material is spilled on the equipment.
Do not use the bath to heat any material that could cause a fire or any other kind of hazard.
