Water Connection
Refer to General Specifications for water supply
information.
Rigid pipe connections are not recommended.
Connections should be supplied by a hot and a cold
water line of at least the sizes shown in the Water
Supply Line Sizing table. Installation of additional
machines will require proportionately larger water
lines. Refer to Table 3.

To connect water service to machine with rubber
hoses, use the following procedure:
1. Before installing hoses, flush the water system
for at least two 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, use flexible
hoses with screen filters.
Each hose is connected to a hot or cold water faucet
with a 3/4" hose bib.
Install vacuum breakers and check valves when
required by local codes.

Install a screen filter in each hose to keep rust and
other foreign particles out of the solenoid valves.
Suitable air cushions should be installed in supply
lines to prevent "hammering" (Figure 5). If the water
pressure is above 60 psi, flexible copper tubing should
be used in place of the rubber hoses.
