Safety Precautions
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.
Read Operating Instructions Thoroughly Prior to Operation
Set-up & Installation
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)

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.
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. Switch on the
ON/OFF power switch. 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)
