WARNING
Hermetic compressor electrical terminal venting can
be dangerous. When insulating material which
supports a hermetic compressor or electrical terminal
suddenly disintegrates due to physical abuse or as a
result of an electrical short between the terminal and
the compressor housing, the terminal may be
expelled, venting the vapor and liquid contents of the
compressor housing and system.
If the compressor terminal PROTECTIVE COVER and gasket
(if required) are not properly in place and secured, there is a
remote possibility if a terminal vents, that the vaporous and
liquid discharge can be ignited, spoung ames several feet,
causing potenally severe or fatal injury to anyone in its path.
This discharge can be ignited external to the compressor if
the terminal cover is not properly in place and if the discharge
impinges on a sucient heat source.
Ignion of the discharge can also occur at the venng terminal
or inside the compressor, if there is sucient contaminant air
present in the system and an electrical arc occurs as the terminal
vents.
Ignion cannot occur at the venng terminal without the
presence of contaminant air, and cannot occur externally
from the venng terminal without the presence of an external
ignion source.
Therefore, proper evacuaon of a hermec system is essenal
at the me of manufacture and during servicing.
To reduce the possibility of external ignion, all open ame,
electrical power, and other heat sources should be exnguished
or turned o prior to servicing a system.
