A drain system of adequate capacity is
essential to the machine performance.
Ideally the water should empty through a 3
inch vented pipe directly into a sump or
floor drain. See figure.
A flexible connection must be made to a
vented drain system to prevent an airlock or
siphon effect. 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
manufacturer. Increasing the drain hose
length, installing elbows, or causing bends
will decrease drain flow rate and increase
drain time, impairing machine performance.
If the drain arrangement is inadequate, the
machine will not extract and will not
discharge water properly.
See table below for specific drain
information.
