Replacement Options
When installing new laundry equipment or replacing existing equipment, consider
the following replacement options:
••
For coin- or card-operated, single-load clothes washers, choose models that are
ENERGY STAR qualified.
32
ENERGY STAR qualified washers use significantly less
energy, water, and detergent compared to standard models.
••
For multi-load washers, choose models that use no more than 8.0 gallons per
cycle per cubic foot of capacity.
••
For washer extractors, choose machines with built-in water recycling capabili-
ties that can store the rinse water from the previous load for use in the next load.
These types of washer extractors can use less than 2.5 gallons of water per pound
of fabric.
••
For large industrial or commercial laundries, consider replacing old washer
extractors or multi-load washers with tunnel washers if large volumes of laundry
will be processed.
••
Choose new machines that support remote diagnosis by the manufacturer to
minimize maintenance cost and time associated with troubleshooting equip-
ment problems.
