10. Routine checking & Maintenance
Gasman II is designed to operate with little
maintenance under most conditions. The following
routine maintenance is recommended.
WARNING - Substitution of components may
impair intrinsic safety.
10.1 General
If used in dirty conditions, a regular wipe with a
damp cloth will help in viewing the display and
maintaining operation of the pushbuttons. This is
also recommended for the side fixing screws to
maintain good contact for battery charging or data
communication.
10.2 Sensor Filter
Dirt should be removed from the sensor apertures
as this may impede diffusion. For access to the
sensor filter, remove the fixing screws and top
moulding (Section 10.4).
