Removing Vapor-logic3, installing Vapor-logic4
1. Access humidifier subpanel as follows:
• Vaporstream and CRUV: Open control cabinet door by
loosening the screws on the two door latches.
• Vapormist and Humidi-tech: Remove plastic shroud by
unscrewing four Phillips screws (Figure 10-1) securing shroud
to frame (save and re-use screws). Remove galvanized subpanel
cover by unscrewing two Phillips screws securing cover to
subpanel (save and re-use screws).
2. Disconnect Vapor-logic3 keypad/display cable and ribbon cables
from Vapor-logic3 main board and expansion boards, if any.
Ribbon cables will not be re-used.
3. Torque all terminal block screws to 2.5 in-lb (0.28 N·m) to prevent
wires from pulling loose in Step 5.
4. Mark location of Vapor-logic3 main board on subpanel by making
corner marks on subpanel with felt-tipped marker.
5. Use pliers to pull terminal blocks from Vapor-logic3 main board.
Unscrew stand-offs, and remove board and stand-offs (they will not
be re-used).
6. Leaving adhesive backing paper on the six nylon stand-offs
packaged with Vapor-logic4 adaptor board, push stand-offs into
adaptor board mounting holes, as shown in Figure 10-2.
7. Plug Vapor-logic4 keypad/display cable into Display connection
on Vapor-logic4 adaptor board (see Figure 11-1). If present,
plug laptop or network cable into Ethernet connection on adaptor
board.
8. If upgrading to Vapor-logic4 without LonTalk® interoperability
(see Figure 11-2), skip this Step. If upgrading to Vapor-logic4
with LonTalk interoperability, disconnect wires from Vapor-logic3
LonTalk pins and land them as instructed in Table 10-1.
