Before installation, carefully read the information in
the use and maintenance manual. All maintenance
operations must be carried out according to the

the presence of gases and vapors (example: EN60079-14,
EN 60079-17 or other national regulations/standards).

Check that the polyurethane foam inserted in the
lid is not damaged.
The preheater must be properly earthed by means
of the anti-loosening and anti-rotating device.
Make sure that the earthing of the preheater is
always guaranteed and ensured.
The user must periodically check, depending on the type of use and the substances used:
• the state of wear and correct operation of the preheater;
• the presence of abnormal vibrations and/or noises. In this case, stop the preheater, identify the causes and contact the manufacturer.
Nonetheless, residual risks may be present during normal preheater operation if:
• is not subject to the normal maintenance plans provided for in the use and maintenance manual;
• is not used as required by the project specifications.
