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.
Correct Leaking Draw-Off Valve
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 Petro-Gel to
prevent the plug from sticking.
