PREPARE THE TELESCOPING POLE
Section 3.3: Install the rain cap assembly
•
Each telescoping pole tip requires a breathable rain cap to allow for venting of the EHU as well as protec-
tion from water ingress. The rain cap assembly (PN 10
-
1105
-
11) consists of a specially cut vent hose,
and a vinyl housing as shown in
figure 3.2
.
•
The fit of the plastic housing on the pole tip is purposely very tight, so that the rain cap assembly will stay
in place. Before attaching the plastic housing, spread a small amount of dish soap or isopropyl alcohol
around the inside edge of the plastic housing as shown in
figure 3.2
. This helps the housing slide on
easily, and the soap will eventually evaporate, leaving you with a firm interference fit.
•
Insert the plastic housing onto the telescoping pole tip as shown in
figure 3.2.
Be sure that the telescop-
ing pole bottoms out on the vent tube.
