TOOLS FOR MAINTENANCE, TEST, AND OPERATION
Normal hand tools including a small pipe wrench is all that will normally
be required to maintain the RI 2400. Coil removal must be performed with
the assistance of an overhead crane, block and tackle, fork lift or other
rigging which will be capable of lifting heating coil (275 lbs) up and
out of coil casing (approximately 10 feet high).
Electrical test can be performed with a volt/OHM meter and/or a continuity
tester and test light.
