EVH
units feature double inlet centrifugal fans mounted on an adapter plate.
The supply fans are clearly visible beneath the main access panel.
To remove/replace, unplug as per Fig. , undo the fixing screws and carefully remove the
fan/adapter plate assembly, retaining all fixings.
To replace the fan assembly, secure one fixing leaving enough of a gap to allow the adapter
plate to slide into place. Fit the remaining fixing and tighten both. Ensure the impeller is free
running.
Reconnect the supply plugs as in Fig. ; if more than one plug is used, ensure the
correct plugs are reconnected as marked.
The fan mounting plates are slotted to aid plate alignment. It is important to keep the fan
assembly supported at all times; the fan assembly should not be considered supported until
all fixings are securely tightened.
