explosion, fire or product damage could result.

E Series product equipped with a quasi-explosion-proof
motor, however, allows Class 2 petroleum mist (such as kerosene) and Class
3 petroleum mist or higher of Class 4 hazardous substances to flow into the
product. However, make absolutely sure that the mist temperature is below
the flash point.
Since the CRH Series Mistresa use oil seals on the shafts, be sure to make
the mist flow into the product for lubrication. (See (6) in section
“Cautionary Notes on Operation”
on page 20.)
* Class 3 petroleum mist having the flash point higher than 150°C may flow
into the CRM-S, CRM-V or CRMH-S Series Mistresa provided that the
suction temperature of the mist is 50°C or lower (80°C or lower for the
CRMH Series). Be absolutely sure to use the burnout prevention terminals
A and B (white leads) in the operation circuit so that the motor would not
experience an excessive temperature.
* Note that some mist substances may deteriorate the packings and filters.
