CHAPTER THREE
SECTION 3.4
DIRECTOR 1 EHU (continued)
INSTALLING THE CPVC INNER GUIDES—DIRECTOR 1 (continued)
Insert the #16 Stainless steel hose clamp (PN 60-5000-15) onto the CPVC tube as shown in
figure
3.46
. Position the black rubber coupling until it is aligned with the CPVC tube and then slide the hose
clamp onto the rubber coupling.
Grip the end of the guide tube that is protruding out of the EST and rotate the tube as needed while
pushing the guide tube in until the black rubber coupler bottoms out against the EHU as shown in
fig-
ure 3.47
. Tighten the hose clamp firmly as shown in
figure 3.48
. Wait 20 minutes and then tighten it
again to guard against cold flow of the plastic. Repeat for the other side of the EHU.
Figure 3.49
shows the completed inner guide tube assembly.
Figure 3.50
gives you an idea of how far
out the CPVC inner guide tubes will extend when glued together. This is why we recommend you wait
until much later in the process to complete the guide tube assembly.
