WARNING: VERY HIGH VOLTAGE IS PRESENT ON THE FORK TERMINALS.
REMOVE POWER FROM THE UNIT BEFORE INSTALLING, REMOVING, OR MAKING ADJUSTMENTS
GUIDELINES
The following precautions should be observed when installing and operating an LP II device:
• The installation and wiring of this product must comply with all national, federal, state, municipal and
local codes that apply.
• The LP II Series are precision devices - handle carefully to prevent damage to the forks.
• Do not allow moisture to enter the electronics enclosure. Conduit should slope downward from the LP II
housing. Install drip loops (or drain tting) and seal conduit with silicone rubber product.
• The resonant frequency of the forks is 85 Hz (±10%); locations subject to this vibration frequency should
be avoided.
CAUTION: ATTEMPTING TO TIGHTEN THE UNIT BY ROTATING THE HOUSING OR FORKS MAY
DAMAGE THE UNIT AND VOID THE WARRANTY.
CAUTION: WHETHER MOUNTING DIRECTLY THROUGH A SIDE WALL, OR PIPE EXTENDED AND
MOUNTED VERTICALLY THROUGH THE TOP OF A VESSEL, NEVER ATTEMPT TO MOUNT THROUGH
A FULL COUPLING.
The LP II unit must be located at the position where level indication is desired. The forks may be mounted
through the top or side wall of the vessel. To ensure reliable operation, observe the following guidelines when
choosing the mounting location.
• DO NOT mount the forks in an area where they can contact the vessel.
• The forks assembly must be horizontal or pointing downward. DO NOT mount the forks pointing upward.
• If the unit is to be used with powders, it should be installed vertically, or at a downward angle that
exceeds the angle of repose to reduce material build-up on the forks.
