Plumbing (Continued):
Water Inlet, Outlet Connections:
When tightening all connections on this unit, be sure to support the internal plastic piping as close as
possible to the plumbing connections, to prevent excessive torque or strain from being applied to the
internal plumbing of the unit.
The various plastic piping connections available (Unions, Flared tube fittings, etc) do not require very
much force to properly seal. Once the plumbing connections have been made, test the connections for
possible leaks and repair any leaks as needed.

(nut) of the fitting.
7) Attach the male and female union halves to create the inlet connection and tighten the union
