Condensate Drain Trap; Condensate Overflow Switch - LG AR-DR12-05A Installation And Operation Manual

PIPING INSTALLATION

Condensate Drain Trap

This unit is equipped with a stainless steel condensate pan with a
stainless steel connection. It is important that the drain connection
be fitted with a P trap to ensure proper drainage of condensate while
maintaining internal static pressures and to prevent migration of
sewer gas back into the unit.
A P trap assembly (kit) is supplied with each unit and is to be
assembled and installed as local conditions require and according to
the assembly instructions provided with the P trap. If local and area
codes permit, the condensate may be drained back onto the roof,
but a drip pad should be provided beneath the outlet. If local and
area codes require a permanent drain line, it should be fabricated
and installed in accordance with Best Practices and all codes.
In some climates, it will be necessary to provide freeze protection for
the P trap and drain line. The P trap should be kept filled with water
or glycol solution at all times and it should be protected from freez-
ing to protect the P trap from damage. If severe weather conditions
occur, it may be necessary to fabricate a P trap and drain line of
metal and install a heat tape to prevent freezing.

Condensate Overflow Switch

This unit is equipped with an optional factory-mounted condensate
overflow switch. In the event that a high level of condensate is de-
tected, a dry contact will be powered (24 VAC). This dry contact can
be used for field monitoring of condensate levels. All monitoring and
control shall be provided by others.
Due to our policy of continuous product innovation, some specifications may change without notification.
