NOTICE
Precautions when making knockout holes:
▪
Avoid damaging the casing.
▪
After making the knockout holes, we recommend you remove the burrs and paint
the edges and areas around the edges using repair paint to prevent rusting.
▪
When passing electrical wiring through the knockout holes, wrap the wiring with
protective tape to prevent damage.
Protect the piping as described in the following table to prevent dirt, liquid or dust
from entering the piping.
