For use with M.G. Chemicals photofabrication products for the etching professional printed circuit boards for prototyping or small production run requirements.

WARNING: Heating unit must be unplugged to turn off. Do not leave heating unit unattended while it is in use. Do not let Etching tank run dry. Do not attempt to operate etching kit if tank is less than 3/4 full. Avoid skin contact with Etchant or direct breathing of vapor.

Cleanup with warm soapy water. Used etchant should be placed back into original container, write "waste material" on the container and dispose of it in an environmentally safe fashion in compliance with local waste regulations.

Instructions:

1. Mount the heater opposite to the spout end of your etching tank as per diagram A. DO NOT PLUG IN HEATER.
2. Secure the tank within its mounting bracket and screw the bracket to the surface you will be working on. With, and sparging unit positioned in the tank, ensure the etchant solution is filled to the level indicated on the quartz element of heater;
3. Wait 15 minutes for the thermostat to adjust itself to the etchant temperature;
4. Plug in the heater;
5. The heater's thermostat has been preset to the correct temperature. However shipping and handling may have effected settings and final temperature adjusting may be required. The pilot light should turn on and remain lit until the operating temperature has been reached.
6. Allow the heater to operate for one hour. When the desired temperature is reached the pilot light will turn off and the heater will maintain the temperature.

Air Pump Installation:

1. Air Pump must be placed above the etching tank at the highest level of etching solution. This will prevent a backflow of etchant into the pump, causing damage to the pump and leakage of etchant.
2. Connect the airline to the output on pump. The pump is operational when once plugged into wall outlet.
