DriSteem Vapor-logic version 3 Conversion Instructions

Vapor-logic version 3 to Vapor-logic version 6 Field
®
Conversion Instructions: CRUV
The drawing at right depicts the
Vapor-logic version 3 board orientation
in a CRUV humidifier control cabinet
without SSRs. The board would be
oriented horizontally in a control cabinet
with the SSR option.
These instructions pertain only to CRUV
humidifier units with Vapor-logic control.
This does not apply to CRUV units with
the standard onboard controller.
1. Leave the wires connected to
the Vapor-logic version 3 board
terminals. Use needlenose pliers to pull the terminals off of the pins.
2. Remove the six screws holding the Vapor-logic version 3 board to the
subpanel, and remove the board. When removing the screws, take care
to prevent the standoffs behind the board from falling down the subpanel
and into other electrical components.
Note: The Vapor-logic version 6 board has adhesive-backed standoffs that
adhere to the subpanel. For the best adhesion, make sure the subpanel
surface is clean and dry.
3. Note the Vapor-logic version 6 board orientation shown in Figure 3-1.
Remove the adhesive backing paper from the Vapor-logic version 6 board
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.
4. 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.
5. Skip this step if the humidifier does not have the SSR option:
Disconnect wire #434 from Vapor-logic version 3 terminal 34, and
connect it to Vapor-logic version 6 P19 plug terminal +SSR. Disconnect
wire #435 from Vapor-logic version 3 terminal 35, and connect it to
Vapor-logic version 6 P19 plug terminal –BL.
6. Disconnect the wires from Vapor-logic version 3 terminals 1, 3, and
5, and connect them to the following Vapor-logic version 6 P17 plug
terminals: Connect wire #401 to FILL, wire #403 to DRAIN, and wire
#405 CT1.
