Alliance Laundry Systems PHM798N, PHM802N manual Air Cushions Risers

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.” Refer to Figure 23.

For machines labeled with the CE mark, backsiphon protection devices must be installed previous of all machine water inlet valves in accordance with accepted European standards.
