4.2.1.1. Placement Requirements

Place oven directly on the floor.

Allow adequate clearance for explosion relief. Minimum clearance for explosion relief is 18
in. above the oven.

Plumb and level the oven to assure proper heat distribution and operation of all mechanical
components.


If placing the oven in an area where excessive particulate matter exists (such as a construction
site or coal processing center), periodically clean all its electrical compartments. Keep power
supply within the specifications provided by Despatch, and use a line conditioner for a
facility with an unstable power supply.
4.3. Exhaust Connections
The RFD oven exhaust discharge opening is located on
the top left of the oven (Figure 12). Install an exhaust
stack from the discharge opening to the outside of the
building. The discharge opening size is 8.9 x 21.6 cm (3
½ x 8 ½ inches).
Warning!
Do not use the oven in wet, corrosive or explosive atmospheres
unless this oven is specifically designed for a special
atmosphere.
Notice
If more than two elbows are used in the stack, over all airflow
will be reduced. If airflow is reduced, the amount of solvent that
can be safely used with the equipment must also be reduced.
