Thermolec Mini Make Up Air - Manual (Page 7)

Maintenance
Even though Thermolec mini make up air units are designed to operate long term without problems we strongly
recommend a yearly visual inspection. This precautionary step will help to keep your installation operating well.
Note these eventual fi rst signs of problems: signs of overheating on the heater frame, traces of water or rust on
the control box.
A basic checklist would include:
- Check all fuses
- Check the resistance to ground for each circuit
- Check the resistance phase to phase for each circuit
- Check the tightening of connections at all contactors and heating elements
- Check all contactors
Any defective components should be replaced only with approved original parts.
Washable fi lter
Disconnect all power sources before doing any maintenance. This unit is equipped with a permanent fi lter that
should be washed at regular intervals. Check the fi lter after a month of operation. To remove the fi lter, simply
pull on the plastic tab (fi g. 9). If the fi lter is extremely dirty, increase the frequency of inspection. Make sure that
the fi lter is dry before replacing.
