IMPORTANT: Undiluted chemical dripping can damage

the machine. All chemical injection supply dispenser

pumps and dispenser tubing should be mounted below

the washer’s injection point. Loops do not prevent

drips if these instructions are not followed.

IMPORTANT: Failure to follow these instructions could

damage the machine and void the warranty.

External Supplies

For proper communication between the machine and an external

chemical supply system, it is important for the low-voltage signal

power to be connected properly. The included wiring diagram

shows several different options for safe and correct wiring of this

interface.

The preferred method for connecting the wiring from the external

chemical supply system to the machine is to use the 300mA pow-

er of the machine’s 24VAC control transformer, which is inten-

ded strictly for this purpose. Other voltage and current options

are available, but require some wiring changes and must be pro-

vided with an external power source. Under no circumstances

should the high-voltage machine supply connections or source be

used for the communication wiring.

Communication wiring connections, which include a single row

of identified terminal blocks, can be found under a service panel

at the upper back of the machine.

Chemical Injection Using Internal 24VAC Control

Transformer

NOTE: Using the Internal 24VAC 300 Milliamp Control

Transformer is recommended by Alliance Laundry Sys-

tems.

CAUTION

Do not attempt to increase fuse rating or alter wiring

of external chemical supply terminal strip in such as

way that may conflict with the suggested methods

provided on the Optional External Supply Wiring Di-

agram.

IMPORTANT: DO NOT remove the red jumper wire from

the terminal strip.

There are 3 terminals necessary for this connection option.

• Terminal “24VAC COM” is used to connect one side of the

internal control transformer to the external dispenser input

signals common.

• The second terminal is used to connect the other side of the

control transformer to the machine output signals common

through a red jumper wire between “24VAC” and “RELAY

COM”. Refer to Figure 33 .

IMPORTANT: Do not use the transformer terminals if

an external power supply is used.
