This appliance should be connected directly to the fused
GLVFRQQHFWRUFLUFXLWEUHDNHUWKURXJKÁH[LEOHDUPRUHGRU
nonmetallic sheathed copper cable. Allow some slack in the
cable so the appliance can be moved if servicing is ever nec-
essary. A UL Listed, 1/2" conduit connector must be provided
at each end of the power supply cable (at the appliance and
at the junction box).
When making the electrical connection, cut a 1 1/4" hole
in the wall. A hole cut through wood must be sanded until
smooth. A hole through metal must have a grommet.
