Water Connection
Table 6
Connections should be supplied by hot and cold water
lines of at least the sizes shown in Table 7. Installation
of additional machines will require proportionately
larger water lines. Refer to Table 7.
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 washer-extractor’s inlet hoses
for proper fit and cleanliness before connecting.
3. Hang the 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 washer-extractor will
function properly at lower pressures, increased fill
times will occur. Refer to Table 6.
Table 7
Suitable air cushions should be installed in supply
lines to prevent “hammering.” Refer to .
