3.3 Circuit Diagram * *Important installation instruction If a geothermal heat exchanger is not provided, we recommend the installation of a preheater unit for the outside air. This prevents icing of the heat exchanger at extreme ambient temperatures. 4. SYSTEM 4.1 Figure 1 The COMFOAIR 140 is equipped with an anti-freeze system without additional auxiliary energy.
4.2 Transport and Packaging Take the necessary care and attention when transporting and unpacking the unit. Damage to the packaging must be recorded on the delivery note on receipt of the goods. Dispose of the packaging materials in an environmentally safe manner. 4.

7. MAINTENANCE / CARE 7.1 General Maintenance of the unit for the end user is limited to the periodic cleaning of the filters and the intake / exhaust air valves and grilles. Twice a year, the texts “FIL” followed by “tEr” appear alternately on the display as a reminder to clean the filters. Cleaning of the valves / grilles is recommended at the same time as the cleaning of the filters. The system must not be operated without filters.
8. MALFUNCTIONS 8.
Fault/malfunction Symptom Display Check No or insufficient Fan not running exhaust air; bathroom or shower remains damp for too long Fan running E1 E1 Loud noise E1/E2 Fan defective Fan pcb defective Control pcb defective Filter clogged Valves/grilles clogged Heat exchanger clogged Fan soiled Ducts clogged Impeller binding or is broken Bearings defective Fan running too fast.
8.2 Bypass Inspection Instructions If 230 V AC is measured between DO3H and N, the flap must open / be open. If 230 V AC is measured between DO4H and N, the flap must close / be closed. Check the connection between pcb and bypass. Air intake and air exhaust fan Check the fans for soiling or mechanical damage. If the fault E1 and/or E2 is displayed, check the wiring. If the wiring is OK, then the fan is defective. The supply voltage to the fans is 230 V.
