7 ROUTINE MAINTENANCE
7.1 Cleaning the Multi Purpose
Regularly use a damp (but not wet) cloth to wipe clean the outer surfaces of the Multi
Purpose, to prevent the entry of dust or other particulates into the gas sample inlet or
the interior of the Multi Purpose.
7.2 Inspecting the inlet filter element
If you only use the Multi Purpose on applications which use clean, dry cylinder gases,
you will only need to inspect the inlet filter element every 3 months. On other
applications, we recommend that you inspect the inlet filter element more frequently.
1. Ensure that the Multi Purpose is switched off.
2. Unscrew and remove the filter retainer cap (see Figure 1).
WARNING
Sample and calibration gases may be toxic or asphyxiant. Never inspect
the inlet filter, remove the side panels from the Multi Purpose, or service
or repair the Multi Purpose while such gases are still connected to it.
WARNING
Sample and calibration gases may be toxic or asphyxiant and may build
up within the Multi Purpose during use. Always inspect the inlet filter,
service the Multi Purpose, or remove the side panels from the Multi
Purpose in a well-ventilated environment, so that such gases (if present)
do not present a hazard.
WARNING
Sample and calibration gases may be toxic or asphyxiant. If you suspect
there is a gross leak or internal pipework damage in the Multi Purpose,
leave the Multi Purpose in a well-ventilated environment for at least
8 hours before servicing or repair.
