Line voltages may vary in some geographies. If the line voltage for your RFD1-42-2E oven varies
more than 10% from the oven voltage rating, electrical components such as relays and
temperature controls may operate erratically.
If the line voltage is lower than the oven voltage rating, heat-up time may be significantly
longer and motors may overload or run hot.
If the line voltage is higher than the nameplate rating, motors may run hot and draw excessive
amperage.
Uniformity figures are based on a nine-point test conducted in an empty oven after stabilization period.
Uniformity can vary slightly depending on unit and operating conditions. Minimum operating temperature
and cooling times are based on 20ºC ambient temperature measured at the fresh air inlet with the fresh air
and exhaust dampers fully open. Specifications are subject to change without notice.
An oven designed for 240 volts (see oven nameplate) will operate satisfactorily on a minimum of 208
Volts, but will result in 25% reduced heater output. If your power characteristic is lower, contact Despatch
Industries.

Class A ovens are designed for a specific amount of solvent.
Exceeding this amount could result in an explosion. Do not
process closed containers of any substance or liquid in this
oven because they may explode under heat. In case of fire, leave
door(s) as they are. Shut off electricity. Shut off fuel. Call the fire
department. Stay away.

contains important information and warnings. Ignoring these warnings can result in death, serious
injury or damage to the machine and product.
2.1.1. Lockout
Machine lockout places the RFD1-42-2E oven into a zero energy state and prevents accidental
machine start up. Always follow the Lockout Procedure described in this section before cleaning,
maintaining or repairing the RFD1-42-2E oven.
2.1.1.1. Lockout Requirements
1. Every power source that can energize any element of the RFD1-42-2E oven must be shut off
at the closest possible power source. This includes air, water, electricity, and the Disconnect
Switch (if applicable).
2. After energy sources are locked out, test to ensure circuits are de-energized.
2.1.1.2. Lockout Procedure
Personnel authorized to lockout equipment must have the necessary locks to perform the lockout.
1. Physically disconnect all electrical power to the machine or lockout the appropriate breaker
or disconnects.
2. Close all valves and bleed off any pressure.
3. Test for power by attempting a start with the machine controls.
4. Identify the Lockout Condition with a tag on the electrical disconnect and pneumatic shut off
valve.
5. When work is complete, remove all tags and restore the machine to its working state.
