Drain Connection Requirements

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. Figure 14 and Figure 15 show drain line and drain trough configurations.

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.

IMPORTANT: The top of the vent must be 1 foot (30 cm) lower than the bottom of the dispenser.

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.

Specifications and Dimensions

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.

Installation of additional washer-extractors will require proportionately larger drain connections. Refer to Table 4.
