Condenser Fan/Coil
WARNING
BEWARE OF MOVING PARTS. Allow time for fan rotation to
cease before opening access door.
WARNING
ELECTRICAL HAZARD. Ensure Isolator is in the OFF
position before opening access door.
The condenser fan intake grilles should be visually checked on a regular basis to ensure
they are free from obstruction with no impedance to air flow.
In order to access the Condensing unit, the cover must be removed using the 4x Hex
Socket screws. (Fig 26).
FIG 26
Check that the Condenser Core and fan grille are free from obstruction.
FIG 27
If it is thought likely the underside of the condenser coil may be obstructed, air applied
as shown below may help improve TCM operating performance (FIG 27).
