Drain Connection Requirements
A drain system of adequate capacity is essential to
washer-extractor performance. The water can empty
directly into a sump or floor drain. Figure 21 shows
the drain line configuration and Figure 22 shows the
drain trough configuration.
Figure 21
A flexible connection must be made to a vented drain
system to prevent an air lock and to prevent siphoning.
IMPORTANT: Washer-extractor must be installed
in accordance with all local codes and ordinances.
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 drain flow rate and
increase drain times, impairing washer-extractor
performance.
Figure 22
Refer to Table 6 for capacity-specific drain
information.
Installation of additional washer-extractors will
require proportionately larger drain connections. Refer
to Table 7.
