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.
