Water Connection
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. See table.
To connect water service to machine with
rubber hoses, use the following procedure:
1. Before installing hoses, flush the water
system for at least 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, use
flexible hoses with screen filters. Each hose
should have a screen filter installed to keep
rust and other foreign particles out of the water
inlet valves.
Pressure of 30 – 85 psi (2 – 5.7 bar) provides
best performance. Although the machine will
function properly at lower pressure, increased
fill times will occur.
Suitable air cushions should be installed in
supply lines to prevent “hammering.” See
Figure 38. If the water pressure is above
60 psi, flexible copper tubing should be used in
place of rubber hoses.
