MACHINE FUNCTION
Cold air is drawn into the dryer cabinet interior through louvres in the cabinet base, passes through
the large hole in the inner back panel adjacent to the fan and is driven through the element housing
on the inner back panel. After passing through the element windings and through holes in the drum
back plate into the drum interior, the now warm air is driven through the load to the front of the drum.
A webbing seal, fixed to the inside of the inner back panel, prevents warm air being driven into the
cabinet interior. As the drum revolves, the load is tumbled through the warm air stream, that extracts
moisture from the damp fabric. The now moist and cooled air passes through the filter in the air duct
on the back of the front panel, where any fluff picked up from the load is removed. The air then travels
through the front to rear air duct, leaving the dryer at the rear outlet.
If required, a vent hose may be attached to the outlet, to take exhaust air away from the dryer.
A cut-out on the element housing, cuts the electricity Live supply to the element, if the air temperature
in the housing becomes too high due to a restriction in the air flow, e.g a blocked filter. The cut-out
automatically resets when the air temperature drops to an acceptable level and cycles if the fault
persists.
A second 'one shot' cut-out, mounted alongside the 'auto reset' cut-out, is fitted as a safety device to
break the element Neutral connection, if the air temperature reaches an unsafe level due to failure of
the 'auto reset' cut-out.
There are two thermostats in the front air duct when only one is in use at any one time depending on
which programme is selected. These sense the exhaust temperature rise when the load becomes
dry and energise the timer motor on the main timer. This allows it to advance to cool run.
