7.3 Fan Replacement
The aircycle 3.1 heat recovery system has a very straight forward fan replacement process
should the unlikely event of a fan failure occur.
Step 1.
Isolate the unit from the mains and ensure all supply circuits are disconnected.
Step 2.
Unscrew the side plugs and remove.
Step 3
. Remove the side panel.
Step 4.
Unplug the two leads from the fan.
Step 5.
Unscrew the scroll assembly from the casing and remove the scroll assembly.
This Whole assembly should be returned to Brookvent.
Step 6.
Place the new scroll assembly in the recess in the case and ensure the holes line
up with the screw insert. Fix the scroll assembly to the case.
Step 7.
Re-plug the connectors (they are two different types so they cannot be mixed
up).
Step 8.
Re-fit the end panel.
Step 9
fit the side plugs, (the long plug always fits in the centre hole), and screw to fix.
Step 10
. Power the unit on at the isolator and ensure any supply circuits are
reconnected. The unit will not need to be re-commissioned as the controller will hold
the settings.
