Water Connection
The models are delivered with three hoses with
3/4 inch hose connectors. These hoses fit the water
inlet valves of the machine and the main water inlet
taps. To ensure the optimal functioning of the water
inlet valves, the water pressure on the inlet should be
between 30-85 psi (2-5.86 bar). If the pressure is too
low, the cycle time will increase considerably.
Connections should be supplied by a hot and a cold
water line per national and local codes.
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 for
proper fit and cleanliness before connecting.
3. Hang the hoses in a large loop, do not allow them
to kink.
If additional hose length is needed use flexible hoses.
Pressure of 30-85 psi (2-5.86 bar) provides best
performance. Although the washer-extractor will
function at lower pressures, increased fill times will
occur with some loss of supply flushing.
Suitable air cushions should be installed in supply
lines to prevent “hammering.”
To avoid personal injury, recommended
inlet water temperature should be no
higher than 125° Fahrenheit (51° Celsius).
