M.5.10 Plug fans
Dust can accumulate on the fan impeller which can cause imbalance and vibrations. The fan impeller must therefore be checked once a
year and cleaned, if necessary. Anti-vibration mounts and flexible connections should be checked at the same time. If the anti-vibration
mounts are damaged in any way they must be replaced.
M.5.11 Motor
The motor are usually fitted with factory lubricated bearings which require no further lubrication. Larger motors can be fitted with
greasing nipples and bearings which require regular lubrication. Lubricating these types of bearings must be carried out according to the
manufacturer’s instructions.
M.5.12 Silencer
During operation dust particles can accumulate on the surface of the baffles. Silencers that are designed for dry and wet cleaning are
fitted with baffles that can be extracted from the unit casing. Large inspection doors give access for easy extraction of the baffles.
Baffles designed for dry cleaning can be cleaned using a soft brush or they can be vacuum cleaned. Baffles designed for wet cleaning
can be washed down using a soft brush and soapy water. The detergent used must be non-aggressive. After washing, the baffles must
be wiped dry with a cloth. Remember to clean the inside surface of the unit casing before refitting the baffles.
M.5.13 Outdoor air section
Dust and dirt can accumulate in this section. Large inspection doors give access for cleaning.

N.1 Protective measures and additional protective measures
Adjustment and maintenance must be done by skilled technicians.
The units are provided with guards to avoid unintended hazards and injury because of rotating parts in the unit. The potential sources of
harm are the fans with fast rotating impellers. Hazards from the impellers are obvious during operation, but when power is cut-off, the
impellers are still potential hazards due to after-run for at least 120 seconds.
The fan guard’s are the inspection doors and the doors are provided with locks.
Other motor-driven parts are dampers with damper motors and rotary heat exchangers. Keep hands away from places with risk of injury.
Use particulate respirator when filters are replaced.
N.1.1 Necessary protection measures prior to start-up
Ensure that all protection measures are installed correct before start-up.
