Use tools to tightly seal the doors before commissioning (unit tightness),
otherwise there is a risk of motor overload.
Carry out air flow rate tests with the doors closed.
Route test hose connections out of the unit (see flow rate calculation).
Changes are made via the BMK programming unit (see relevant operating
Note
instructions).
To prevent the electric heating coil from switching off, never operate the CRL

Follow the relevant safety regulations for electric heating coils.
The electric heating coil must be protected from moisture and water.
The filter pre-dryer starts automatically at outside temperatures below 5 °C.
