IV. MECHANICAL INSTALLATION
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 rod.
• Do not allow moisture to enter the electronics enclosure. Conduit should slope downward from the LP II housing.
Install drip loops (or drain fitting) and seal conduit with silicone rubber product.
• The resonant frequency of the rod is 400 Hz (±10%); locations subject to vibration frequencies greater than 100
Hz should be avoided.
CAUTION: WHEN MOUNTING UNITS, NEVER ADJUST THE ORIENTATION BY TURNING THE HOUSING. USE A
WRENCH FOR PROCESS FITTING UNITS, OTHERWISE A STRAP WRENCH SHOULD BE USED TO TIGHTEN INTO PLACE.
ATTEMPTING TO TIGHTEN THE UNIT BY ROTATING THE HOUSING OR ROD 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.
WARNING: HIGH VOLTAGE IS PRESENT. REMOVE POWER FROM THE UNIT BEFORE INSTALLING, REMOVING, OR
MAKING ADJUSTMENTS.
WARNING: IN ORDER TO MAINTAIN SAFE OPERATION IN HAZARDOUS LOCATIONS, THE INTEGRITY OF THE
ALUMINUM CASTING AND THE ENVIRONEMENTAL SEALS MUST BE MAINTAINED. THE USER/INSTALLER
MUST AVOID INSTALLATIONS WHERE AGGRESSIVE SUBSTANCES MAY BE PRESENT AND COULD AFFECT THE
PERFORMANCE OF THESE MATERIALS. CARE MUST ALSO BE EXERCISED WHEN REMOVING AND REPLACING THE
COVER, SO NO MARRING, SCRATCHING OR DAMAGE OCCURS TO THE FLANGES, AND THAT FLANGE SURFACES
REMAIN COMPLETELY CLEANED OF DEBRIS.
WARNING: FOR UNITS INSTALLED IN HAZARDOUS LOCATIONS, TO REDUCE THE RISK OF IGNITION OF HAZARDOUS
ATMOSPHERES, CONDUIT RUNS MUST HAVE A SEALING FITTING CONNECTION WITHIN 18 IN. OF THE ENCLOSURE.
WARNING: FOR PRODUCTS MARKED AS TYPE 4X, USE TYPE 4X HUB FITTING; FOR IP66 USE IP66 HUB FITTING.
