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.
