PREPARE THE TELESCOPING POLE
Section 3.2: 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.
