1.Open the cabinet base doors, remove the two screws from the contactor box cover and lift cover off.

2.Disconnect the electrical lead wires to the coil and the power supply wires from the contactor being replaced.

3.Remove the screws form the base of the contactor and lift out.

4.Reverse procedure to install and check for proper operation.

HEATING ELEMENTS

WARNING: DISCONNECT THE ELECTRICAL POWER TO THE MACHINE AT THE MAIN CIRCUIT BOX. PLACE A TAG ON THE CIRCUIT BOX INDICATING THE CIRCUIT IS BEING SERVICED.

1.Open the cabinet base doors, remove the two screws from the contactor box cover and lift cover off.

2.Disconnect the electrical lead wires to the element being replaced.

3.Remove the bolts securing the heating element flange to the boiler and lift the element out.

4.Clean the mating surface of the boiler and install a new flange gasket and heating element.

5.Check for leaks and proper operation.

WARNING: DISCONNECT THE ELECTRICAL POWER TO THE MACHINE AT THE MAIN CIRCUIT BOX. PLACE A TAG ON THE CIRCUIT BOX INDICATING THE CIRCUIT IS BEING SERVICED.

WARNING: SHUT OFF THE STEAM SUPPLY BEFORE SERVICING THE UNIT.

1.Disconnect pipe unions in the steam supply line to the coils and in the condensate discharge line from the coils.

2.Remove header that supplies steam to the coils by disconnecting union at each coil.

3.Remove coil condensate collection header.

4.Remove bolts securing the coil being replaced and pull coil forward.

5.Clean the mating surfaces of the steam coil flange and the boiler.

6.Reverse procedure to install a new steam coil and gasket.

7.Check steamer for proper operation.
