Cleaning
The
Aspida units
should be cleaned using a damp cloth only. Abrasive or solvent products should not be
used.
The only exception to this is if the unit has been accidentally immersed in dirty or salt water. In this
situation only, the gas sensing ports should be rinsed with a gentle flow of clean water before leaving
the unit to dry, to ensure the pores of the membranes over the sensors are not blocked by dirt or salt.
The unit should be turned off after accidental immersion and not turned on again until it has completely
dried. After accidental immersion (and rinsing if necessary), excess water should be shaken from the
unit then the unit must be allowed to air-dry completely before using.
This may take a few hours in cool or damp conditions, during which time unit should be left turned off.
If the unit is turned on whilst the membrane is damp, the reading will be low (due to excess water
vapour) often enough to cause an alarm, and will also drift as the water evaporates. If the unit is
recalibrated whilst the membrane is still damp, this drift will continue so invalidating the calibration. For
this reason, after accidental immersion the unit should be left in a dry environment to completely dry
before subsequent use.
