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.

NOTE: If a flexible connection is made directly to a drain system, the drain system must be vented to prevent an air lock and siphoning.

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.
