be replaced by a new one. The power supply should be free of heavy objects during the
VWR Thermal Shake lite's operation. Keep the power supply away from high traffic
areas.
Connect the A.C. Power Line
While connecting or disconnecting the power line, user should insert the plug firmly to
ensure good contact between the plug and socket. Pull the plug, but not the cable,
when the plug needs to be disconnected from the mains.
Design Environments
The VWR Thermal Shake lite should be placed in a low-humidity, dust-free, well-
ventilated room without caustic gas or powerful magnetic interference. The VWR
Thermal Shake lite should not be operated in close proximity to water sources, such
as pools and water pipes. Never cover or obstruct the openings of the VWR Thermal
Shake lite, which are designed for ventilation and to prevent the device's interior from
becoming too hot. When a single device is running, the shortest distance between its
openings and the nearest object should be at least 50cm (20 inches); when two
devices or more are running simultaneously, the shortest distance is 100 cm (40
inches) among these machines. Do not place the device on a soft surface. Doing so
will result in adverse ventilation near the device's bottom openings.
Operating conditions that cause a high temperature environment will result in
degraded performance or failure of the The VWR Thermal Shake lite. Additionally,
the device should be protected against any kind of heat sources such as sunlight,
ovens, or central heating equipment. If the VWR Thermal Shake lite will sit idle for
extended periods of time, it is recommended to disconnect the power line from the
mains and cover the device with a piece of soft cloth or plastic to prevent against
dust.
Once one of the following events occurs, the Operator is advised to
disconnect the power cable from the mains, and contact the distributor or ask
a certified maintenance engineer for assistance.
Liquid enters into the device;
The device malfunctions, giving off an abnormal sound or odor;
The device falls onto the floor or the housing is damaged
