1. Cautionary information indications used in
this manual
2. Meanings of symbol marks used in this manual
"[ ] WARNING" mark indicates cautionary information that, if not
heeded, could result in serious injury or death, and could also
pose a fire hazard.
A "[ ] CAUTION" mark indicates cautionary information that, if not
heeded, could result in injury and/or equipment damage.
WARNING Do not install in hazardous locations
3. Using the Mistresa in a safe manner
The Mistresa does not have a pressure and explosion-proof construction.
Operating the Mistresa in areas where explosive gases, etc., are present
could result in an explosion in the event of an electric motor burnout.
(CRH-□□E Series except.)
CAUTION! HOT
This product collects oil mist generated by equipment such as machine tools
to ensure and maintain a comfortable working environment. Do not use the
product for any purpose other than the originally intended.

The high efficiency motor (IE3) used with the Mistresas of the CRM-S (H02
excluded), CRM-V (H02 excluded) and CRMH-S series is designed with a lower
winding resistance than the standard motor (IE1 and equivalent), in order to reduce
loss. Since this design feature requires a higher starting current than the
standard motor, replacing your existing motor may require that you also
replace the circuit breaker, thermal relays and other parts.
