Note: Some units are loaded with fork trucks and do not require cart track extensions.
The following sequence of events occurs after the oven is turned on:
• The process chamber is purged with air equal to four times the combined volume of the
process chamber, oxidizer chamber and the stack.
• The oxidizer burner fires upon completion of the process chamber purge cycle.
• Once oxidizer chamber reaches 1400 degrees Fahrenheit the process burner fires.
• The process burner will remain “on” during the entire heat cleaning cycle. Once set point
has been reached the process burner cycles between high fire and low fire to maintain
that temperature. The set-point temperature can be varied easily depending the material
being processed. Normal processing temperatures are between 550
0
F and 800
0
F.
• The oxidizer burner remains “on” during the entire heat cleaning cycle. Once set point
has been reached the process burner cycles between high fire and low fire to maintain
that temperature.
• If the oxidizer flame fails to establish at start-up, the process burner will not fire.
• If the oxidizer burner fails during operation, the process burner will shut down.
• If the process burner fails, the oxidizer burner will continue operating.
4.6 Operating Procedure
A step-by-step description of the normal operating procedure is presented below.
1. Load the platform cart or rack with the doors fully open and ensure that:
• The load is placed so as to allow for good heat flow from underneath the cart. If a cart
is totally blocked off it will cause cart warpage and improper cleaning of the load.
Parts are stacked carefully to prevent wall damage.
• The recommended minimum clearance between the load and the hanging misting
nozzles is 6". This will assure proper misting on the load when required.
2. Turn on the panel power.
3. Press the OTS Test button located on the panel door and visually checks the misting
nozzles. The nozzles must mist to be effective. If the load blocks the nozzles or if a
steady stream of water is flowing, they are totally ineffective. Damaged nozzles should
be replaced immediately.
4. Close the doors.
