Steam Requirements (Steam Heat Op-
tion Only)
WARNING
Hot Surfaces. Will cause severe burns. Turn steam
off and allow steam pipes, connections and compo-
nents to cool before touching.
W505
For machines equipped with optional steam heat, install piping in
accordance with approved commercial steam practices. Steam re-
quirements are shown in

WARNING
Dangerous Chemicals. May damage eyes and skin.
Wear eye and hand protection when handling chemi-
cals; always avoid direct contact with raw chemicals.
Read the manufacturer’s directions for accidental
contact before handling chemicals. Ensure an eye-
rinse facility and an emergency shower are within
easy reach. Check at regular intervals for chemical
leaks.

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 Dia-
gram.
