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 Cautionary notes on using the CRD-H, CRH-H,
and CRN Series Mistresa
WARNING Fire and electrical shock prevention
WARNING Maintenance and inspections prohibited
during impeller rotation
The Mistresa wiring work must be performed by a qualified electrician, and must
conform to the relevant electrical engineering standards and
internal wiring standards.
CAUTION For after installation transport
If you want to transport by installing the product on the device, please
fix firmly with as rope hanging. It may cause malfunction or damage.
Always wait at least 2 minutes after a power OFF before performing
filter replacement work or inspections (to allow the impeller's inertial
rotation to come to a complete stop).
WARNING Fire and explosion prevention
Never allow explosive gases , organic solvents , or flames to be sucked
into the suction port. (
CRH-□□E series, please use in the range of 8 page
described.)
Mistresa from CRD-H, CRH-H, and CRN Series use high efficiency motors (IE3)
that are designed to have lower motor winding resistances than the standard
motors (IE1 or equivalent) so as to reduce losses. Since this design feature calls
for a higher starting current, replacing the motor of your existing Showa
Denki’s Mistresa may require to change the circuit breakers, thermal
relays, and other relevant devices.
