7.10 Filters Maintenance Guidance
7.10.1 VRC filters
There are two filters for each unit. A filter net is mounted on the condenser air in side (PN: 02560118). And
another is mounted on the return air side (PN: 02560155). To ensure the normal operation of the filter, the
filter service alarm logic is provided by the controller. The default fan running time is 2000 hours (settable
according to the local running environment), when the time is exceeded, the filter service alarm is
triggered. The filter needs to be replaced based on its clogged condition. The filter must be checked once a
month and be replaced as required during operation. If the VRC unit is used in a dirty environment, please
check the filter once a week.
