Filter Change
All filters in the air handling unit (inc. cooling module) are
monitored by the unit’s filter monitoring system. The filters
must be replaced when the monitoring system indicates a
filter change, but at least annually. Filter monitoring can be
adapted to local conditions using Airlinq Service Tool. The
filters are tested automatically daily at 12 noon (time can
be set using “Airlinq Service Tool”).
NB: When changing filters, the unit must be switched
off (press function button for at least 2 seconds),
disconnected from the mains and prevented from
being switched on.
NB: The control system filter monitoring must be reset
after a filter change.
