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 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.
