Installation
Drain Connection
Figure 28 and Figure 29 show typical drain trough and
drain line installations.
Connect the drain outlet to a vented drain system using
only a flexible connection. The drain system must be
vented to prevent an air lock or siphoning.

Use the supplied black rubber adapter and clamps to
transition from the machine drain outlet to the two
inch schedule 40 PVC plumbing (20, 25 and 30
models) and the three inch schedule PVC plumbing
(40, 60 and 80 models).
If proper drain size is not available or practical, a surge
tank is required. A surge tank along with a sump pump
should be used when gravity drainage is not possible,
such as in below-ground-level installations.
