Negative-Pressure Application
When operating with a negative pressure plenum,
install the RLC
Air-Trap
in a horizontal orientation with
the arrowhead pointing in the direction of water flow
and the clean out plug facing upward as shown in Fig.
6. Condensate enters the end of the trap with the
centered connection and leaves the trap that has the
off center connection.

showing arrowhead pointing in direction of water flow.
RLC traps tested at 1.6 GPM of condensate flow.
Figure 7: Orientation for negative pressure after
installation of RLC
Air-Trap,
showing cleanout port on
top, condensate entering at left end center, and exiting
at lowest point of trap on the right side. No water
remains in trap shortly after condensation ceases.
The benefits and maintenance of the RLC
Air-Trap
when used in the negative pressure mode are the
same as for the positive mode with the added benefit
that it eliminates the geyser effect that is caused when
the standard P-Trap dries out and condensate begins
to form. The geyser effect is when air rushes into the
HVAC unit and does not allow the condensate to drain,
causing water to blow throughout the plenum
compartment. In addition, the RLC negative
Air-Trap
requires less than half the height of a P-Trap.
Dimension Y in Fig. 6 illustrates that the total height of
the
Air-Trap
is only the height of the negative pressure
plus one inch and not 2 times negative pressure plus
two inches. Dimension Y in inches is = negative
pressure in inches of water column.

Caution, do not puncture the Float Valve.
