Drain Connection
A drain system of adequate capacity is essential to
washer-extractor performance.
Ideally, the water should empty through a vented pipe
directly into a sump or floor drain.
shows drain line and drain trough
configurations.
Figure 10
A flexible connection must be made to a vented or air
gap drain system to prevent an air lock and to prevent
siphoning. If proper drain size is not available or
practical, a surge tank is required. A surge tank in
conjunction with a sump pump should be used when
gravity drainage is not possible, such as in below-
ground-level installations.
Before any deviation from specified installation
procedures is attempted, the customer or installer
should contact the distributor.
Increasing the drain hose length, installing elbows, or
causing bends will decrease, impairing washer-
extractor performance.
Refer to
for capacity-specific drain
information.
Installation of additional washer-extractors will
require proportionately larger drain connections. Refer
