CONTROL PANEL OVERVIEW
4.1 Power Switch: The main power I/O (on/off) switch controls all power to the unit
and must be in the I/ON position before any systems are operational.
4.2 High Limit Thermostat: This control is marked HIGH LIMIT and is equipped
with an adjustable knob and a graduated dial from 0-10. It is independent of the
Main Controller and guards against any failure which would allow the
temperature to rise past the Main Controllers set point. This allows continued
operation of the oven until the problem can be corrected or service can be
arranged. It is not recommended that the unit be operated for extended periods
of time using only the Overtemperature Safety as the controller as temperature
uniformity will suffer.
4.3 High Limit Activated: This pilot lamp will come on when the High Limit
Thermostat is activated and taken control of the heating element. Under normal
operating conditions this pilot lamp should never be on.
4.4 Main Temperature Controller: This is a microprocessor based temperature /
Time Control with ramp and soak capabilities ( Watlow model 981 ).
4.5 Fuse: Located at the back of the unit next to the power cord, the fuse provides
protection for the units electrical circuitry against power fluctuations. When
blown, the fuses must be replaced before the unit can continue operation.
4.6 Power Exhaust Outlet: Located at the back of the unit next to the power cord,
for easy installation of a power exhaust accessory. The 05012-30 does not come
equipped with this feature.

PRECAUTIONS
5.1 This unit has been designed with vents from the chamber. In order to work
effectively and safely, some precautions will need to be taken by the operator.
a. In most applications, the exhaust damper will need to be open during
drying or degassing for best results.
b. THIS OVEN IS NOT DESIGNED TO HANDLE COMBUSTIBLE GASSES,
AND IS NOT AN EXPLOSION PROOF OVEN. DO NOT PLACE
EXPLOSIVE, COMBUSTIBLE OR FLAMMABLE MATERIALS INTO THE
CHAMBER.
c. Some of the out gassed byproducts may be hazardous or unpleasant to
operating personnel. If this is the case, the exhaust should be positively
ventilated to the outside and dealt with according to local regulations.
Contact your dealer about power exhausts.
5.2 Do not operate near noxious fumes.
5.3 Do not place sealed or filled containers in the oven chamber.
5.4 Do not cut or remove the ground prong from the power cord.
5.5 Do not use a 2-prong adapter plug.
5.6 Be sure that the power supply is as the same voltage as specified.
5.7 Disconnect the unit from its electrical source before proceeding to make any
electrical repairs or replacement.
5.8 If a mercury thermometer is used and breakage should occur, all spilled mercury
MUST be completely removed from the chamber before continuing operation.
5.9 This oven is NOT designed for the use in Class I, II, or III locations as defined by
the National electric Code.
5.10 This oven is not intended, nor can it be used, as a patient connected device.

CLEAN ROOM READY INSTRUCTIONS
The 05012-30 and 05012-40 have been designed to operate at class 100 standards. It
is not shipped clean room ready and the instructions below must be followed for proper
installation. See Figures Two and Three.
6.1 BURN-IN OF THE HEPA FILTER
Before using this oven, it is important that the filter be Òburnt-inÓ properly. During
burn-in, the Hepa filter will off gas. Because of this, the intake and exhaust port
must be open with the exhaust port being ducted outside. A material safety data
sheet is included with your operation literature for reference.
A. To burn in filter:
1. Set oven at: 175°C for 1 hour;
220°C for 4 hours;
225°C for 1 hour;
250°c for 1 hour.
2. If operating temperature is higher than 250°C, continue the cycle of
one (1) hour at 25° increments until the operating temperature is
achieved.
B. After burn-in, the interior must be disassembled and cleaned. Make sure
unit is unplugged before disassembly. This requires an 8/32 nut driver to
remove the cap nuts. Remove the bottom liner insert before removing the
liner side inserts.
6.2 CONTROL AREA EXHAUST
As part of this design the control compartment is sealed and requires a minimum
of 30 C.F.M. (Cubic Feet Per Minute) to be drawn from the control compartment
exhaust port. This is required to limit control compartment temperature and
maintain Class 100 integrity. If you are unable to exhaust the minimum 30
C.F.M. from the control compartment, then you must limit the maximum operating
temperature to 280°C. Operation of the unit above 280°C, without required 30
C.F.M. control compartment exhaust will result in control degradation and
Section

process failure. Not supplying the required 30 C.F.M. may also keep the unit
from operating at class 100 specifications by allowing particulars from the control
compartment to escape into the room.

OPERATION
7.1 Power Supply: As mentioned is Section 3.1, be certain the power source
matches the requirements listed on the data plate.
7.2 Turn the power switch to the I/ON position and turn the High Limit Thermostat to
its maximum position, clockwise. This allows the setting of the Main
Temperature without interference of the High Limit..
7.3 Set Main Temperature Controller: This is explained in full detail in the enclosed
Watlow 982 users manual. A simplified 981 instruction sheet is included with the
manual for your convenience. Please refer to the users manual and instruction
sheet for operation and maintenance details.
7.4 Set High Limit Thermostat: Prior to setting the High Limit Control be certain the
Main Temperature Control has reached the input set point and has remained
stable for several hours. This will insure that the High Limit is set at the proper
temperature. As mentioned in step 7.2, the High Limit should be at maximum
position. Now turn the Thermostat counterclockwise until the High Limit
Activated indicator light comes on. Next, turn the Thermostat clockwise just until
the light turns off. Then turn the Thermostat two (2) of the smallest divisions on
its scale past the point where the indicator light went out. The High Limit should
now be set approximately 10° higher than the Main Temperature Controller.
Please note that the High Limit is a safety feature only. If the unit is allowed to
operate using only the High Limit Thermostat, the temperature stability will suffer.
7.5 Power Exhaust Outlet: The power exhaust outlet is controlled by the Main
temperature Controller. This is described in paragraphs 2 and 3 on the back
page of the 981 simplified instructions and in the Watlow 982 users Manual. The
05012-30 does not come equipped with this feature.
