Operation
Door Lock Switch
The DPF Thermal Processing Unit is designed
with a feature that locks the chamber door when
the internal temperature is greater than 93°C
(200°F).
This feature is designed to prevent personal
injury from fire, as well as damage to the DPF.
If the chamber door is opened at temperatures
over 93°C (200°F), the DPF could crack due to
uncontrolled, rapid cooling known as thermal
shock.
In severe cases, opening the door could result
in a fire if the DPF contains a large amount of
unburned hydrocarbon.
1. If the chamber door must be opened, and the
internal temperature shown on the control
panel is less than 93°C (200°F), press STOP
/ BACK. Press the door lock switch on the
control panel to open the door. See Fig. 7.
Completion of a Cycle
1. When the cycle is complete, CPLT appears
on the digital readout, and the electronic
controller turns off the thermal unit.
Do not open the door until the digital readout on
the control panel displays room temperature.
2. Manually turn OFF the power switch.
Storage
1. When the unit is not in use, close the door to
the chamber and unplug the power cord from
the wall socket.
