Step 1: Remove Water Control Board 


Disconnect the float switch leads from the board. Disconnect the Black, Blue, and White wires from the board. Remove mounting screws/nuts with a #2 Cross-tip screwdriver and a ⅜” wrench or socket. Remove water level control board.


Step 2: Install Relay Unit


Using a 3/16” drill bit, increase the size of the mounting holes on the Relay unit.


Use the Relay unit to determine the position of the mounting holes it will use.

Reuse the top hole of the Water Control Board as one of the mounting holes for the relay.

Use a punch or other suitable marking method to mark where the second mounting hole should be, and drill it with the 3/16” drill bit.


Securely fasten the Relay unit to the inside of the Steamer base. The location of the Relay unit should be in approximately the same position as the Water level Control Board.


Step 3. Attach Power and Controlling Wires


The Retrofit kit should come with the wires pre-inserted into the Relay. As shown in the image below.  NOTE: Wires may come loose during shipping.



Use the Black wire provided in the retrofit kit, attach the female end to the COM connector of the relay. Attach one of the male connectors to the black power wire.  Attach the other male connector to one of the smaller twisted-pair of wires coming from the Float Switch.


NOTE: Wires coming from the Float Switch will be a smaller gauge and are in a twisted-pair configuration. In this document, the wires are Blue, however they can be another color.


Use the White wire provided in the retrofit kit, attach the 3/16” female spade connector to one of the magnetic coil leads on the Relay. Attach the male connector to the White Neutral wire.


Use the Purple wire provided in the retrofit kit, attach the 3/16” female spade connector to the other magnetic coil lead on the Relay. Attach the male connector to the other twisted-pair of wires coming from the Float Switch.


NOTE: Magnetic coil uses A/C current, so the 3/16” spade connectors can be interchanged without affecting the operation of the Steamer.


Connect the Blue wire to the NC port of the Relay.



The Steamer is now ready for testing and usage.
