18 PNEG-1744 H-Series Catwalk Installation
3. Installation Instructions
For Step 1, please refer to the instructions included in the original manual. Follow Step 2 in this
supplement. Then, return to the original manual for Steps 4-8. (Step 3 in the original manual is
obsolete for dryers without buttresses.)
Step 2: Build catwalk support assemblies (part numbers: D04-0499, D01-2425 and D01-2437). Refer to
Table on Page 12 to determine the number of support assemblies and catwalk platforms needed for the
dryer, based upon its length and the number of modules.
Step 3: To install the assemblies on the dryer: A two-stack dryer will have one catwalk on the top module.
A three-stack dryer will have one catwalk on the middle module, as well as one on the top module.
NOTE: There are places where you must install supports where there is no stiffener. (See Figure 2I
on Page 14.) To determine if this situation is applicable to the particular dryer, please refer to
Table on Page 12 , as well as dryer layouts and locate the dryer size.
Now, return to the original manual for Steps 4-8.
To install the catwalk support assembly on the middle module, measure 17.54" from the top of the stiffener
to the top of the assembly (D04-0499). Use the hardware referenced in
Figure 2J on Page 16 .
To install the catwalk support assembly on the top module, measure 16.57" from the top of the stiffener to
the top of the assembly (D04-0499). Use the hardware referenced in
Figure 2K on Page 17 .
Once all supports are in place, install catwalk sections as indicated in Table on Page 12 and dryer catwalk
layouts, using the appropriate layout length.
Step 9: On the truss bracket, install the plate with the hole when there is a gap between catwalk sections.
See Figure 2G on Page 13 for these connections and Table on Page 12 for the quantities required.
On the truss bracket, install the plate without the hole where the support needs to go in the center
of the catwalk.
See Figure 2H on Page 13 for these connections and Table on Page 12 for the
quantities required.
Go to Step 13 of the existing manual to finish the hand rail installation.
