Electrical Service
The
ZIMMER
vaporizer is manufactured as an explosion proof
device suitable for hazardous locations. Do not separate the heat
exchanger to access the electrical enclosure –
separating the
enclosure will void warranty!
♦
When connecting the electrical service for the
ZIMMER
you will
need a circuit breaker appropriate for the application. See
Electrical Specifications in the Appendix.
♦
You will also need a disconnect switch located within sight of
the vaporizer (refer to Electrical Specification in Appendix).
♦
Select the appropriate size conductors based on the current
draw (refer to Electrical Specification in Appendix) and
conductor run distance (see reference charts below).
♦
Install metal terminal box to the ¾” MNPT seal-off to make the
wiring connections in accordance with the local electrical codes.
Ensure the terminal box is connected to seal-off before
vaporizer is mounted to wall.
