Fancom I-FAN Manual page 19

Analogue and digital

When overloaded, the I-fan will adjust itself back on the basis of maximum power. If the RPM is lower than
93% of the maximum RPM, an alarm will sound.

For other malfunctions, the I-fan will start itself up again independently after a short while. If the motor does
not start up then, the alarm relay will be switched off. If the I-fan no longer starts independently, the I-fan
must be removed from power for at least 30 seconds and then be started up again.
Digital

If I/O communication is interrupted, the last set value remains active.

Turning the power supply on and off without I/O communication will activate the predefined setting of
dipswitch 8 (ON=50%, OFF=100%, see also page 10).
The I-fan requires no specific maintenance. Fancom recommends that your installation technician inspects the
complete climate installation, of which the I-fan is a component, every half-year.
Inspect the I-fan periodically for any damages. Notify your installation technician immediately of any
damages. A damaged I-fan is unsafe!
Check the I-fan for proper functioning regularly.
There must always be power to the I-fan. This prevents the formation of condensation in the I-fan.
When the mains power is interrupted, the alarm relay is also interrupted.
The I-fan may be cleaned wet, but consider the following:
Do not use a high pressure hose or aim at motor seals or openings at close range.
The fan should be turning. This makes for a better seal at the shaft ends and prevents water flowing into
the motor. It is recommended that the fan turns at 50%. If so, water will be discharged faster by the
airflow.
This fan has protection class IP66.
After cleaning the I-fan, it should run at 100% rpm for at least 30 minutes to remove all dampness.
When disposing the I-fan please comply with all relevant requirements and regulations applicable in your country.
