INJECTION SOURCE CONNECTIONS
The washer control may be programmed to send six 120V output signals
for a chemical injection system of up to four chemical sources. The
signals are not intended as a power source and must be limited to less
than 100 milliamps of current. There is a separate terminal block for
connection of the external injection signals. For the injection sources,
program codes 0 through 6 and their respective terminal block
connections are as shown in Table 3.

Table 3: Injection Signal and Circuit Identification
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" (35.5 cm) and a maximum of 18" (45.7
cm) to eliminate chemical buildup in the pipe and/or restrict water flow to
the tub. Secure the hoses as required.

OPERATION CHECK
After all mounting, plumbing and electrical work is completed, select any
desired wash cycle and run the machine through a complete wash cycle.
Check for water leaks and verify proper operation.
During intermediate spin and final spin, the cylinder should turn in a
counterclockwise
direction when viewed from the front of the machine.
If spin is clockwise, the T1 and T2 motor wires connecting to terminal T1
and T2 on the variable frequency drive should be swapped. Remove
power to the machine before opening service panels and swapping wires.
