14 Maintenance
VP Series 2000 devices have been design to require minimal maintenance. Maintenance tasks
include cleaning the sensor for maintenance purposes, periodic inspection of device components
such as batteries and o-ring seals, cell replacement as well as firmware updates.
14.1 Cleaning
Use a non-abrasive solvent free method to clean the exterior of a VP Series 2000 device prior to
performing any further maintenance to the device. A clean, dry, anti-static cloth should be used to
clean interior components of the device. Switch cleaner may be used to remove deposits from sensor
body contact pads.
Warning!
 To prevent electrostatic discharge, only a damp cloth may be used to clean the exterior of VP
Series 2000 devices in hazardous locations.
 Opening, disassembly and internal cleaning shall never be performed in hazardous locations.
14.2 Disassembly
Disassemble a VP Series 2000 device as follows:
• Remove the enclosure retainer using oscillating turns to prevent damage to the o-rings. Use a
single counter-clockwise turn followed by a ¼ turn in the opposite direction until the sensor
body o-ring is exposed.
• Remove the e-module by using light, upward pressure on the side opposite the contact pins.
• Remove the cell retaining ring using the cell installation tool.
• Remove the cell.
Warning!
 Do not disassemble the device in a hazardous environment.
 If the cell is damaged or shows signs of leakage do not continue with the disassembly
process and take appropriate action as per applicable hazardous materials procedures
provided in the cell manufacturer’s material safety datasheet.
 Do not short-circuit the cell.
Note!
 VP Series 2000 devices should not be disassembled in the field.
 Avoid disassembling the device in humid conditions.
