and the water flow rate.
Maintenance and Techniques for Cleaning the
RLC
Air-Trap
Preventative Maintenance
In some operations, large particulate matter can move
from the HVAC unit through the drain line and into the
Air-Trap
, causing a malfunction or failure. The best
way to reduce maintenance is to install a strainer
screen at the inlet to the drain line (Fig. 1) or a
Des Champs
Union-Strainer™
upstream of the
Air-
Trap,
(See Fig.
5
) to prevent miscellanious items like,
rocks, screws, and nuts from ever getting into the trap.
The
Union-Strainer™
is also a convenient way to
prevent unwanted creatures and objects from entering
at the terminus of the drain line, like snakes, rats,
lizards, insects, and plant growth.
The water flow is in
direction of arrow shown in Fig. 5, with the strainer cup
oriented to capture debris within the cup.
There are several options for cleaning. Option 1
is to
use the ½-inch threaded cleanout port in the trap
housing. This will allow insertion of a water or air
hose/syringe for washing or blowing away material that
may be hampering operation of the trap. See Fig. 3.
Option 2 would be to isolate the
Air-Trap
using unions
that allow
Air-Trap
removal for cleaning.

upstream of the Air-Trap. This will aid in preventing
debris from entering trap. The arrow shows the
direction of water flow, into the strainer basket.
