Installation - Automatic Door Opener - PizzaMaster PM 721 Owner's Manual

Automatic door opener
All oven doors in the PizzaMaster 700, 800 and 900
series can be equipped with an automatic door opener
as an optional extra.
Each automatic door opener has a powerful 3-phase
motor that open or close the oven door alternately by
each press on the foot pedal.
This enables the baker to have both hands free when
loading or un-loading the oven. It also relieves the arms
and shoulders from the stress of opening the oven door
manually many many times during a working day.
The door opener has a mechanical safety clutch that
enables the oven door to be opened manually at all
times.
