Figure 26: Read the user manual
Maintenance
Read the user manual before performing service or
maintenance on the product.
Failure to respect service and maintenance schedules
may cause damage that is not covered by product
warranties.
Cleaning the product
Warning! Do not use a high-pressure
water jet for cleaning. Take care not
to damage seals and wiring during
cleaning.
Warning! Disconnect from power
before cleaning.
Cleaning schedules vary depending on the
operating environment. It is therefore impossible to
specify precise cleaning intervals for the product.
Environmental factors that may result in a need for
frequent cleaning include airborne dust and pollution.
Inspect products frequently to see whether cleaning is
necessary. If in doubt, consult your Martin
®
by Harman
dealer about a suitable maintenance schedule.
To clean the product, use warm water and a soft
brush or a low-pressure or medium-pressure water jet.
Use car shampoo to help remove dirt and grease. If
possible, dry with a soft cloth to avoid streaking. Do not
use a stiff brush or scouring pad. Do not use solvents
or abrasives.
Figure 27: Pressure relief valve
Cleaning the pressure relief valve
Make sure that the valve (1) is clean and unblocked.
The valve must be able to breathe freely so that it can
equalize pressure and expel water vapor. If a valve
becomes blocked, excessive pressure can damage
seals or cause air and water to be sucked along cables
and into the product.
Water on the valve membrane will block the
membrane’s micropores. Do not allow water to collect
on or near the valve. If you suspect that a valve has
become blocked with dirt, contact your Martin
®
by
Harman dealer.
