PERIODIC CLEANING
Every 6-12 months (depending on dust in the place where it is installed), blow a jet of compressed air downward through the cooling heatsink
(on the opposite side of the fan).
In this way both the heat sink and the cooling fan are cleaned.
IN THE EVENT OF OVERTEMPERATURE ALARM
If periodic cleaning does not eliminate the problem, perform the following operations:
1. Disconnect the fan cables from the terminal block (if present) or disconnect the fan connector from the GRM-H (FAN63).
2. Unscrew the screws securing the fan to the support brackets
3. Check the condition of the fan, clean it or replace it
4. Reassemble the fan
