Safety information, installation and maintenance This document does not contain sufficient information to install the product safely. See the Installation and Maintenance Instructions supplied with the unit for full details. Warning: This product contains materials including plastics which can give off toxic fumes if exposed to excessive heat. Installation note: The LP11-4 is designed for installation in a BSP Rp1 (1" BSP tapered) threaded flange or cover. Note: Always specify these thread for new installations. A minimum 80 mm (3") nominal bore protection tube is recommended if installing the probe in a boiler, or in a tank which is subject to very turbulent conditions. Additional environmental protection is needed for installation outdoors. Wiring note: Wiring is straightforward on the LP11-4, as crimp connectors are used. Extra connectors are available as a spares kit. Terminal posts are colour coded for easy identification. The wiring loom may be disconnected and removed without disturbing the cable gland by lifting the gland carrier out of the lower housing. Maintenance note: No special maintenance is required, though boiler water level controls do require periodic testing and inspection which is described in separate literature.
