1. Note the board orientations shown in Figure 3-1. The photos depict
the orientation of the Vapor-logic version 3 board before removal, and the
recommended Vapor-logic version 6 board orientation.

2. Remove the six screws holding the Vapor-logic version 3 board to the
front panel (see photo below). This will allow for board movement during
terminal removal.

Vapor-logic version 3 board
is mounted to the back
of this panel.

3. Leave the wires connected to the Vapor-logic version 3 board terminals.
Use needlenose pliers to pull the terminals off of the pins.

Note: The Vapor-logic version 6 board has adhesive-backed standoffs that

adhere to the subpanel. For best adhesion, make sure the subpanel
surface is clean and dry.

4. Remove the adhesive backing paper from the standoffs, and press the
Vapor-logic version 6 board onto the subpanel as close as possible to the
original footprint of the Vapor-logic version 3 board.

5. See Figure 3-1. The Vapor-logic version 3 disconnections and
Vapor-logic version 6 connections needed for this conversion are labeled.

Note: If any wires are too short to reach their new locations on the

Vapor-logic version 6 board, add pigtail extensions to them.
