Appendix C ArcShield Chimney Installation Instructions
Cabinet Preparation
In preparation for mounting a chimney, the cabinet lifting means (slips of
lifting angles) must be removed. Reinstall the 5/8-11 bolts retaining the lifting
means in the holes from where they came (11 lb•ft [14.5 N•m]) (
Failure to do this will remove the cabinets ability to properly control any arc
gases. Once the lifting angles or clips are removed, remove the 1/4-20 fasteners
(12 lb•ft [15N•m]) from the relief vent on the top of the MV enclosure.
The chimneys are designed to fit over the fastener heads at the (4) corners of
the Relief vent. The corner fasteners are required to secure the Relief vent
during installation.
ATTENTION:
Hardware used to retain the lifting provision hardware
must be reinstalled in the same holes (
). Failure to replace
this hardware will make the arc resistance of the cabinet ineffective
and could subject personnel to the possibility of severe burns, injury,
or death.
IMPORTANT
Do not remove the four corner fasteners (
