Safety information, installation and maintenance

For full details see the Installation and Maintenance Instructions supplied with the product.

Installation note:

Screw the pocket into a 1⁄2" BSP connection on the vessel, using PTFE tape as a thread sealant. The austenitic stainless steel dial thermometer

can be screwed directly into the vessel if required.

Position the thermometer so that it will measure a representative temperature in the vessel. Vertical mounting thermometers have a minimum

insertion depth - see dimension 'H'. Heat conducting paste is not normally necessary, but may be used if desired.
