Water Connection
The 18-135 models are delivered with hoses with
3/4 inch hose connectors. The 165 model is delivered
with 3 x 1 inch and 1 x 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
(2-5.7 bar). If the pressure is too low, the cycle time
will increase considerably. In case of boiler fed
machines, a maximum of hot water of 194°F (90°C)
should be available:
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 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 length is 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 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).
