*1 In the case of severe damage, change tubing as a preventative measure.
*2 O-rings and filters are part of the servicing set for annual servicing, part
# 030460 00073 0.
*3 The load that the F1 filters are subjected to is monitored by the unit. At 80%
load, the unit signals that the filter will soon need to be changed. At 100%
load, minimum throughput is no longer guaranteed so measurements are no
longer possible. When the filter is changed, the date of change is saved
simultaneously. The filter should not be used for longer than 12 months. After
12 months, a recommendation to change the filter is shown in the display and
in the MES. Always change both F1 filters at the same time. Filter set, part #
030460 00072 0.
Important:
–
Only use the blue or black F1 screw-in filters.
– Only remove the filters from the unit when replacing them against new
ones. Used filters must not be reinstalled into the unit.
*4 The voltage status of the O
2
sensor is monitored by the unit. At 5 mV, a
recommendation to change the sensor is displayed. At 3 mV, it is no longer
possible to start a 4/5-gas measurement. At lower levels, the sensor voltage
drops by roughly 1 mV per month under normal operating conditions. This
rate may differ significantly if climatic conditions are unfavourable (i.e. high
humidity, extreme temperatures).
*5 Regardless of the messages displayed on the unit, the oxygen sensor must be
changed after 12 months at the latest to ensure trouble-free operation.
*6 The battery (on the main board) is designed to have a service life of 12 years.
MAHA recommends changing the battery after 10 years. The service life may
