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.
