NOTE
The top cover must be generally secured with all four screws. Any unknowns that may hinder the performance of
this assembly step must be rectified if necessary.
Commissioning
NOTE
Perform the commissioning process in compliance with the specifications in chapter “2.4.2 Commissioning and
operation”.
Proceed as follows for the initial commissioning:
1. Check the ventilation unit for any damage and for the presence/completeness of all safety and functional assemblies.
2. Energise the mains supply line to establish the operating voltage at the ventilation unit.
3. After an initiation phase of approx. 3 seconds, indicated by the LEDs lighting up, the operating modes can be tested.
Specialist maintenance
Inspection and cleaning of the enthalpy exchanger must be carried out at two-yearly maintenance intervals.
NOTE
Instructions for proper disinfection can be found at www.core.life .
In doing so, proceed as follows:
1. Disconnect the ComfoAir 70 from the supply voltage.
2. Remove the upper design cover. Undo the right-hand fastening screw for the lower design cover and pivot it to the left.
NOTE
For units with ventilation tubes connected at the side, the joining pieces must be removed.
3. Pull the unit carefully out of the wall mounting pipe until the rear side of the upper EPP housing is in front of the top
edge of the wall bracket.
NOTE
If a sensor module is installed, then the sensor cable must be disconnected at the SENSOR X8 clamping point on
the control board and withdrawn from the recess in the lower EPP housing.
In order to have free access to the control board, the EPP housing must be pulled out a little further. To do so, the
plug on the ribbon cable must be removed from the control panel, and the lower design cover unscrewed.
