9. Make sure the chamber and any remote equipment provided are leveled when installed. The chamber
door may swing shut on personnel if unit is tilted.
10. A main power disconnect switch is normally not provided with your unit. If not provided, we recommend
that a fused disconnect switch on a separate branch circuit be installed as the power source in
accordance with all National and Local Electrical Codes.
11. Do not position the chamber in a manner that would make it difficult to operate your main power
disconnect switch.
12. Your power supply line voltage may be too low or too high to properly and safely operate your
equipment. Before making the power supply connection to your equipment, you must follow the
specific directions stated under “Power Supply Specifications and Connection” in the Installation
Instructions section. Failing to perform the directions stated may damage your equipment and void
your warranty!
13. Control panels, gauge boxes, the conditioning compartment, etc., contain exposed electrical
connections. Keep panels in place properly when the unit is in operation. Disconnect and Lock-Out /
Tag-Out all electrical power from the unit at its source before servicing or cleaning.
14. Do not adjust any mechanical components or any electrical components except as directed in this
manual.
15. Do not modify any component on this unit. Use only original equipment manufactured (OEM) parts as
replacement parts. Modifications to any component, or the use of a non-OEM replacement part could
cause damage to your equipment, personal injury, or death.
2.0 SAFETY WARNINGS & SYMBOLS

16. Do not overload the floor of the chamber workspace or load the unit unevenly.
17. Do not exceed the temperature rating of your chamber.
18. Human exposure to temperature extremes can cause injury. Do not open oven doors until oven
temperature drops below 200° F (93° C), when applicable. Take appropriate precautions before
opening oven doors and upon handling any chamber contents.
19. Always cool the oven down below 167°F (75°C) before shutting it down. Otherwise, damage to the
circulation motor shaft bearings will result.
INTERNATIONAL WARNING / SAFETY SYMBOL DEFINITIONS
Obey all “DANGER”, “WARNING”, and “CAUTION” labels shown in the manual and mounted on the
equipment. Do not remove any labels mounted on the equipment.
“WARNING OF HAZARDOUS AREA”
“WARNING OF DANGEROUS ELECTRIC VOLTAGE”
“WARNING OF HOT SURFACE”
“EARTH (GROUND) PROTECTIVE CONDUCTOR TERMINAL”

3.1 Application & Specifications
This manual applies to the Blue M Model 146 Series Industrial Ovens, which are designed in three distinct
types and in a wide range of sizes. They serve a very diverse number of process applications. An electric
heating system is used with a high volume air circulation system to provide maximum temperature uniformity.
Model Type Model No. Workspace Temp. Rating
Standard Models Model DC / DCW 1.6 to 24 Ft.315° above ambient to 350° C
Inert Gas Models Model DCI 1.6 to 24 Ft.315° above ambient to 350° C
Clean Room Models Model DCC 1.2 to 21.6 Ft.315° above ambient to 250° C
Standard DC Models are the building block to the 146 Series with a proven high quality design and
simple operation.
Model DCW ovens are identical to the Model DC except that they incorporate a welded and sealed liner,
which creates an impervious barrier between the process chamber and the insulation material.
Inert Gas Model DCI ovens are utilized for processing materials in an inert atmosphere using a gas
injection system. An inert atmosphere prevents oxidation from occurring on the product and eliminates
the capability of oven air from supporting a flame.
Clean Room Model DCC ovens employ a HEPA (or ULPA) filtration system to maintain Class 100
conditions in the oven workspace. An inert atmosphere is also maintained in the Model DCC.
Model DCI and DCC ovens are constructed with an interior that is welded vapor tight. Special seals are
installed on the door, blower shaft, and heater element terminals to ensure the sealed integrity.
Workspace Capacity:
A size code is given in the model number to indicate workspace capacity. Refer to the chart below.
Important! For custom ovens
with sizes not listed in this chart,
the workspace will be given below.
For S/N xxxxxxxxxx, O/N xxxxx,
Model DCxxx, the workspace
capacity is xxx cubic feet.

3.2 Conditioning Functions
Heating of the oven is achieved by recirculating oven air through open air nichrome wire heater elements
mounted in the conditioning plenum. The plenum is located beneath the chamber workspace and is
isolated to prevent direct heat radiation.
Cooling in the Model DC oven is achieved by adjusting dampers with the intake and exhaust ports, which
are normally located on the left side of the oven.
Enhanced cooling is achieved by recirculating oven air through a water-cooled coil mounted in the
conditioning plenum. This feature is optional in the Model DC, and standard in the Models DCI and DCC.
Air flow is generated by a centrifugal type blower wheel mounted in the conditioning plenum. The blower
wheel is directly driven by an externally mounted motor. A horizontal airflow type system is employed.
For the Model DC, a portion of process air may be exchanged with fresh ambient air to remove moisture
or undesirable process vapors. This is achieved by opening the intake and exhaust dampers.
For the Model DC, the air intake and exhaust dampers can be adjusted to provide between a one-pass
airflow system and a full recirculated airflow system within the chamber workspace.
Inert gas systems employed with the Models DCI and DCC utilize a gas injection system that maintains
an inert atmosphere in the oven during the entire process cycle. In the Model DCI only, an initial high
purge cycle will remove oven ambient air before heating is allowed to begin. A constant low flow of gas
will then be maintained during the heating and cooling cycles. Inert gas flow and chamber pressure are
monitored and regulated with various instruments on the gas control panel.
The following inert gases are approved for these ovens.
yArgon
yCarbon Dioxide
yHelium
yNitrogen
3.3 Equipment and Control Features
Temperature Control:
For simple temperature control a non-profiling type controller is normally used. For temperature control with
programming applications a profiling type controller is used. Available controllers are listed below.
