CHEMICAL INJECTION
Dexter T1200 washing machines are intended to be permanently installed
appliances. The machine is intended to have a chemical injection system
operating with it. There are convenient electrical connection points for the
injection pumps shown in Figure 3. Up to four (4) independent pumps can be
controlled through the signals A, B, C and D. The injection pump signals are
24 VAC. The COM shown in Figure 3 is the common or return for these injection
signals.
The four injection pump signals, (A, B, C and D) are individually selected, or
in combinations, by the programming within the selected cycle. The recommended
signal connections are shown in Figure 4. The selection of the signal is
explained in the Programming Instructions section of this manual.

CHEMICAL INJECTION HOSES
Chemical injection hoses are to be inserted into the injection inlet at the
upper right rear of the washer. These hoses should be inserted into the round
PVC pipe a minimum of 14" and a maximum of 18" to eliminate chemical buildup in
the pipe and/or restrict water flow to the tub. Secure the hoses as required.
FINAL CHECKOUT
After all mounting, plumbing and electrical work is completed, the washer
should be checked for water leaks, and proper functioning by first running each
step in the diagnostic cycle, (cycle #31), and by running a complete cycle.
