Installation
Drain Connection
A drain system of adequate capacity is
essential to machine performance. Ideally, the
water should empty through a flexible
connection directly into a sump or floor drain.
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 or using
elbows or bends decreases the
flow rate and increases drain times, impairing
machine performance.
If the machine is equipped with the optional
indirect steam heating/water cooling option,
drainage must also be provided for the two 1/
2" NPT (13 mm) condensate/cooling outlets.
In multiple machine installations, use the
information in the following table to ensure
proper drainage.
