Water Supply Information
Water inlet connection size, in (mm)
Number of water inlets (standard)
Recommended pressure psi (bar)
Inlet flow capacity, gal/min (l/min) (80 psi)
Connections should be supplied by hot and
cold water lines 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 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.

Suitable air cushions should be installed in
supply lines to prevent "hammering." If the
water pressure is above 60 psi, flexible copper
tubing should be used in place of rubber hoses.
