Zehnder Rittling ComfoAir 70 Operating Manual And Assembly page 37

The flaps should be opened at approx. 90° . A large opening angle can lead to collisions with the electric
cabling and to the failure of the device. Switch the device to fan speed 1 and make the settings similar to
the process in the case of setting "Flap position closed". During the setting, never touch the running
ventilators. Also do not look through the shared pipe of the EPP-Casing unit in the running exhaust air
ventilator. There is increased risk of injury.
Filter
The filter run-time can be set here between 60 and 360 days. After the filter run-time had lapsed, a white
LED blinks in the control unit. Our suggestion is for a filter run-time of 90 days.
Frost Protection
These plant settings should never be changed!
