To replace an element, drain the kettle jacket. Remove the wire from the element terminals, remove the four bolts in the element flange and pull element out. When replacing the element, always use a new gasket.
Replace On-Off Switch
Remove the large nut on the outside of the control box holding the unit to the box. The switch has two separate contact blocks held by special slotted screws to the back of the switch. It may be necessary to replace only one block. When remounting on the box, be sure the gasket is properly positioned between the switch and inner surface of the control box and the small pin at the top front of the switch fits into the small hole above the large hole in the control box wall.
Replace Signal Light
Remove the screw between the two signal lights in front of the control box. Note the position of the bar, the signal lights and the gaskets and replace with parts in the same position, with the bar against the back surface of the metal ring on the light, and the gasket around the light and between the metal ring and the inner surface of the control box wall.
Replace Pressure Gauge
Disconnect the copper tubing from the back of the gauge, remove two nuts holding the "U" strap in place, remove the "U" strap and remove gauge.

Remove the plug from the body of the valve. Examine the tapered surface of each. Carefully dress any raised places with a very fine file or with emery cloth. Do not cut below the surface when removing any raised places. Coat the plug lightly with lapping compound, insert the plug in the body and rotate to seat the plug in the body. Use a medium grade of compound first and finish with a fine grade lapping compound. Valve grinding compound from an automobile supply house is suitable for this.
Clean surface thoroughly after use of lapping compound. Lubricate surfaces lightly with
