The following procedure leaves the safety circuit (door interlock and

low water) wired in series with one alarm:

1. Make sure gray-handled jumper supplied with upgrade kit is

inserted into terminals P3-3 and P3-4 on Vapor-logic4 adaptor

board (Figure 15-1).

2. Vaporstream only: Locate wire 801 that runs to expansion board

terminal T1 (Figure 15-2), and land it at terminal P3-3 on

Vapor-logic4 adaptor board. If wire 801 does not reach P3-3, use

a longer 18-gauge, stranded wire. Torque terminal block screws to

2.5 in-lb (0.28 N·m)

Proceed to “Start-up and validation” on Page 19.
