Route test hose connections out of the unit (see flow rate calculation)
note
Changes are made via the BMK programming unit (see relevant operating
instructions)
To prevent overheating, never operate the CFL below a minimum air flow rate
if an electric heating coil is installed.
Follow the relevant safety regulations for electric heating coils.
The electric heating coil must be protected from moisture and water.

The electric reheater is switched by the temperature controller.
Before commissioning, check the manually resettable high limit safety cut-out.
Reset the high limit safety cut-out by pressing the reset button.

Before commissioning the CFL-WRG, set the differential pressure switches on
the outdoor air and extract air filters to a value of 200 Pa (scale dial).
200 Pa
