damage to the electric coils.
The electric coils must be protected from moisture and water.
Check the dampers for ease of movement. Never lubricate the dampers.
This could destroy the plastic used and compromise the damper function.
To clean, wipe down with a soapy solution; otherwise maintenance-free.
The filters are not renewable. They must be replaced when they are dirty, or
no later than after 12 months.
The filters can be removed from the unit once the inspection doors have been
opened (see spare parts).
The clamping levers must be opened (pulled) before pulling out the filters for
the CRL evo max units.
Never operate the CRL ventilation unit without filters!
