1.2 Checking the ventilation fan
The purpose of checking the ventilation fans is to avoid excessively high temperatures
developing in components during operation.
1. Check that the fan rotates and blows air.
2. Clean the fan blades if there is dirt on them.
Checking the fan is necessary because abnormal temperatures can occur during
operation. If the fan does not work, the function of various components can be affected
negatively.
1.3 Checking the panel decal
The purpose of checking the panel decal is so that the machine has the esthetically and
hygienically correct appearance and that users select the correct functions.
1. Check that the panel decal is rmly in place in the right location and it is not torn or
cracked.
2. Check that the symbols on the display are clear and legible.
1.4 Checking the door lock
The purpose of checking the door lock is to ensure that the door is locked during the
process.
1. Check that the door lock and catch on the door are attached rmly.
2. Check the connections on the sensors and locking motor and make sure there is no
damage.
Regularly checking the door lock prevents the machine from accidentally stopping. The
control system is programmed to detect faults in the sensors or motors. The machine will
issue an alarm in the event of an error. See the list of fault codes.
2 Ventilator
The following inspection points must be performed in order to ensure the process.
Deviating from this puts not only the drying process at risk, but the cleanliness of the
items can also be affected and electronic components can be damaged as a result of
leaking steam (due to high temperature and humidity). Leaking steam can also lengthen
the process time.
2.1 Replacing a HEPA filter
Not changing the lter poses the risk of the lter becoming clogged with impaired
ventilation capacity as a result.
2.2 Check fans in terms of their function/connection.
If the fan doesn’t work, the ventilation process will malfunction and leakage can cause
problems in terms of the drying process losing capacity or even breaking down due to
counter pressure in the drainage line.
The fans should be checked and cleaned as needed. The fan should be replaced as
needed, e.g. after it breaks down or when a drop in performance is detected, seal/tighten
leaking connections.
