Read Operating Instructions Thoroughly Prior to Operation
The GC series Lab Ovens are not designed for use with any flammable solvents or gases or in close
proximity to any flammable solvents, gases, or materials. Operate oven in accordance with all state, local, and
federal laws that may govern its usage for your specific application. Use only a grounded outlet that is rated for
your model's electrical requirement. Oven exterior walls and doors may become hot to the touch when operating
at higher set temperatures. Do not leave the oven unattended during operation, especially when processing
materials that may ignite at temperatures lower than the oven model's maximum operating range. Do not modify
the oven or factory control settings to operate the oven above the stated maximum operating temperature.
Conduct periodic maintenance as required.
Safety Precautions
General Operation
Set-up & Installation
FIG. 3
FIG. 2
Set-up unit in a clean and unobstructed operating location. Keep a minimum of 4
inches of airspace around the unit and a minimum of 18 inches above the unit. The
three exhaust ports at the top of the unit will expel a small amount of heated air, fumes
or moisture through natural convection. For best performance, these ports should
remain open. These ports can also be used as an access for an external temperature
probe to verify the chamber's temperature or the chamber's contents directly.
(FIG 1)
Plug oven into a grounded outlet rated for your unit's labeled voltage.
A separate circuit or breaker should be dedicated for the oven.

Install adjustable shelves as required, by placing the ends of the
wire shelf bracket into the corresponding holes located on the inner
sides of the oven at the desired height. Push the ends of the
bracket into the holes until the first bends in the bracket are against
the wall, then rotate the bracket down. Place the shelf on the
brackets.
(FIG 2)
For 20GC, 30GC, and 40GC models: These models come equipped with a
dual-range "quick-set" knob dial. This feature makes it easier to hit a target
temperature range from a cold start, whether using the Fahrenheit or Centigrade
scale.Turn the thermostat knob to the desired temperature indicated on the knob
(Fahrenheit), or the dial (Centigrade).
To set the temperature in degrees Fahrenheit, turn the knob in a clockwise direction
until the desired number on the knob is directly under the white triangle with the "
o
F"
in the center.
(FIG 3)
All models are ready for your immediate use. Remove the glass thermometer from its container and place
bottom end through the rubber grommet. Insert the grommet into one of the ports on the top of the oven and
adjust the thermometer so that it extends at least 2 inches into the oven chamber. For the 10GC series model:
Switch the ON/OFF power switch to the ON position. Turn the thermostat control knob clockwise to around the
number '8'. The light will come on indicating heater activity. Monitor the reading of the thermometer until it
reaches the desired temperature. Next, rotate the control knob very slowly counter-clockwise until the
heat-cycle light goes out. The thermostat will then cycle automatically maintaining the set temperature. Turn the
oven off with the ON/OFF power switch, saving the temperature setting for the next use.
