How to install the fan
Install the fan onto an appropriate flat metal plate having excellent vibration
resistance and heat conductivity.
Drill holes on the mounting plate and fix the fun on the plate using screws.
For air orientation and rotational direction, see the “ AIRFLOW” and
“ROTATION ” indications shown on the fan’s side frame. The direction shown
by the
mark indicates the outlet, while the inlet is in the opposite direction.
The direction shown by the mark indicates the direction of rotation.

Alarm function
The alarm signal is output when the fan’s rotation speed falls below
1800±300 r/min.
Note
The alarm circuit do not have a delay function. Avoiding detection,
when starting the fan, requires an external delay function. Set the
delay time to 10 sec. min.

Overheat protection
●
Impedance protection (
MRE10
,
MRE12
)
Impedance protection means the fan will not burn out in the event of a lockup.
●
Thermal protector (
MRE16
,
MRE18
)
The fan uses a thermal protector for overheat protection. Once the temperature
reaches a specified level, the internal thermal protector that has an automatic
return feature is triggered to stop the fan operation. Be sure to turn off the power
when checking the thermal protector.
Operating temperature of thermal protectors
Open (power OFF): 120±5 °C (248±9 °F)
Close (power ON): 77±15 °C (170±27 °F)
