Commissioning
The procedure detailed under periodic maintenance
should be followed
Periodic maintenance
As detailed in BS 9999:2008
1. For dampers this is at least once per year for
units with spring operation.
2. Units operating in dust laden atmospheres,
should be checked more often to suit the severity
of the conditions
3. Units associated with systems may be required
to be checked, as part of the system, as often
as once per week or month to ensure ongoing
confidence in the life safety system. This may
be seen as analogous to fire alarm systems.
Procedure
1. The units should be carefully inspected and
cleaned of dust and debris
2. The units should then be lubricated with a light
oil, by wiping this over all the surfaces
3. The mode should be operated to ensure that it
is moving the blades from open to closed and the
reverse.
4. If the end switches (in the mode) are being used,
it should be checked that they are actually indicating
that the blades are open or closed. This is done
by running a cycle and checking both the blades
(open and closed) and the indication that the
micro switches are feeding back to.
Actuator fitting (If required)
The control mode/actuator should be fitted in
accordance with the documentation supplied with it.
