Water Connection Requirements
The maximum water inlet temperature for vended
models is 125°F (51°C) and the recommended
maximum water inlet temperature for on-premises
models is 150°F (66°C).
Connections should be supplied by a hot and a cold
water line of at least the sizes shown in Table 8.
Installation of additional machines will require
proportionately larger water lines.
To connect water service to a machine with hoses, use
the following procedure:
1. Before installing hoses, flush the building’s water
system at the machine connection valves for at
least two (2) minutes.
2. Check filters in the machine’s inlet hoses for
proper fit and cleanliness before connecting.
3. Hang hoses in a large loop; do not allow them to
kink.
If additional hose lengths are needed or using hoses
other than those supplied by manufacturer, flexible
hoses with screen filters are required.
Suitable air cushions (risers) should be installed in
supply lines to prevent “hammering.” Refer to
Figure 40.
Alliance Laundry Systems, LLC ranges of front
loading commercial clothes washing machines have
solenoid valves at the inlets. The water supply to the

between the soap tray and the drum. Minimum and
maximum working pressure 1.4 bar and 8.3 bar. The
machines are supplied with approved inlet hoses with
a maximum inlet dimension of 0.50 in. (12.6 mm)
(ID).
NOTE: This machine has a fluid category 5
backflow prevention device built in between the
soap tray and drum.
