Preventive maintenance
Introduction The unit needs preventive maintenance with specific intervals to avoid breakdown or
inefficient operation. It is important to notice that interval between maintenance can
vary depending on the specific environment.
Caution! Switch off all power to the unit before working on the unit!
Make sure that all work has been performed before switching on the power again.
Interval Kontrollelektronik Dantherm Air Handling AB recommends that intervals between
preventive maintenance do not exceed 1 year. It is also our recommendation that the
site and unit is examined closely during the first preventive maintenance to determine
whether the interval is too long. We recommend that preventive maintenance visits are
planned to occur in springtime.
Condition for
warranty The factory warranty is only valid if documented preventive maintenance has been
carried out with an interval of maximum 1 year. The documentation could be in form of
a written log.
Recommended
approach The recommended approach when performing a preventive maintenance visit is:
Step Action
1 Make sure that the power to the unit is safely switched off.
2 Remove the worn-out filter and clean the unit carefully.
3 Clean the dampers and check them regarding function and tightness.
4 Clean the fan and check its mounting.
5 Check and clean the air intake and exhaust accessories.
6 Insert the new filter carefully into the unit.
7 Close the unit and make sure that the service is completed correctly.
8 Turn on the power to the unit.
Function tests Fan and filter alarm function tests can be done by the following actions.
Function test Action
Filter Open the service door and put a plate of carton or similar on the
intake side of the filter, blocking a big part of the filter area. Close the
service door, run the free cooling unit and check that filter alarm is
given. Stop and remove the plate.
Fan Open the lid to the controlling unit and remove one of the cables
connected to the connector marked “Tc1” or “Tc2”. Close the lid, run
the free cooling unit and check that fan alarm is given. Restore the
controller.
