Exhaust Silencer
If an exhaust silencer was ordered with the unit,
the mounting holes are pre-drilled.
To install an add-on silencer:
1. Remove the top door assembly and set aside.
2. Place a piece of non-combustible cloth over the
filters in the clean-air chamber to protect them
from drilling chips.
3. Use a .116-in diameter drill bit to drill eight
holes in the collector top as shown.
4. Position the exhaust silencer, align holes, and
fasten securely with #7 x 1/2-in screws
supplied.
5. Carefully remove the cloth protecting the
filters. Replace the top door assembly and
tighten securely by hand.
