Setting closing speed of the sliding valves
The closing speed of the valves can be set by the air pressure.
•
Set the closing speed of the valves to 4-5 seconds arranged
by the air pressure.
Do not set the valves to faster than 4 seconds. If there is a fire
alarm, the fan is switched off and the sliding valves are closed.
The 4 seconds give the fan enough time to reduce speed and
prevents damage to the duct by negative pressure. Do not
select speeds slower than 5 seconds either, since the
FlameShield modules are activated 5 seconds after the fire
alarm.

Maintenance
In order to function properly the sliding valves must be
inspected regularly.
WARNING
Keep the compressed air feed line away from places
that can become hot by fire. Do not use the
compressed air supply from the filter because this will
be shut off in case of fire. Do not use filter or duct as
support for compressed air hoses.
