CLEANING THE FANS
Check the cleanliness of the fans when servicing the filters
and the heat recovery cell. Clean the fans as required.
You can clean the fan blades with compressed air (wear
protective goggles) or by brushing them gently. Do not
remove or move the fan blade balancing weights.
IMPORTANT
The fans are extremely sensitive to external shocks. It
is recommended that the fans be cleaned in place, i.e.
without attempting to remove them. Remove the fan
beds and the bypass duct carefully in accordance with
the below instructions to prevent damage to the unit.
The small size of the unit restricts the space available
for servicing.
IMPORTANT
Handle the fan blades carefully. Do not remove or
move the fan blade balancing weights.
