5. MAINTENANCE

Attention: before handling and/or opening the access panels it is compulsory to shut down the power supply.
Regular maintenance of the Class Unit is essential to guarantee a good operation of the device and a long life
expectancy. The maintenance frequency will depend on the application and on the actual environment conditions but
in a general way the following controls are advised:

5.1 Every 3 months

1. Check for any alarm indicated on the control device. In case of alarm refer to control manual.
2. Check the state of filter clogging. The control device allows to set a pre-defined 'filter clogging' threshold (refer to
installation manual). If need be replace filters. Filters that are too clogged can generate the following problems:

Insufficient ventilation

Excessive increase of fan rotation speed, creating excessive sound level

Excessive power consumption (power consumption will increase exponentially to an increase in pressure
drop, for a constant airflow)

A damaged filter allows unfiltered air to enter heat exchanger (risk of clogging) and into ventilated room.
List of replacement filters:

HRg Class Unit 1000
3. Inspection and cleaning of the inside of the unit:
- Vacuum clean any accumulation of dust in the unit.
- Inspect and gently vacuum clean if need be the heat exchanger. Use brush accessory to protect fins.
- Clean the possible condensation marks and possible accumulations in the drain pan.
