suitable material.
2 Conduit tube installation
Open by hammering the knockout holes for the conduit tube located on the
base and the bottom part of the front panel.
When installing the conduit tube directly through the knockout holes, remove
the burr and protect the tube with masking tape.
Use the conduit tube to narrow down the opening if there is a possibility of
small animals entering the unit.
When taking the conduit tube out from the bottom part of the unit, caulk
around the tube opening to prevent water penetration.
