repair or maintenance)
• The four main heat exchanger fans are not able to blow enough air through
the ALS thermostat
Suggested Actions: ❏ Check connections of the Peltier elements
❏ Clean the air filters and heat exchanger fins in the ALS thermostat. Switch
off the thermostat and wait 10 min for the peltier elements to equilibrate
❏ Make sure that there is enough space on left and right side of the ALS
