Handling precautions
The fan motor is equipped with a precision ball bearing. Therefore, pleasehandle the motors carefully in order not to shock the bearings.

3. Overheating protection function
Protection Functions:
If the fan blades are restricted, an overcurrent occurs and leads to a rise in
the fan coil temperature. This can result in reduced performance, damage,or a fire. To prevent this from occurring, SANYO DENKI s fans incorporate
an overheating protection function. Refer to the catalog for the types ofprotection functions.
● The burnout protective function of the AC fan
・Impedance protection (60mm sq. 80mm sq. 92mm sq. 120mm sq.)
This system is used for shading coil-type fans. When the blades are
restricted, the current is reduced by the impedance of the coil itself toprevent a temperature rise in the coil. However, if the applied voltage
exceeds the specification range, an overcurrent can occur and result inoverheating, and so care needs to be taken.
・Thermal protection (160mm sq. φ 172mm)
This system is used for condenser phase-type fans. A temperature sensor isincorporated in the coil so that if the temperature exceeds the specification
temperature, the current is cut off to prevent overheating of the coil.
● The burnout protective function of the DC fan and blower
・Current cutoff system
If the fan blades are restricted, the coil current is cut off at regular cycles
to prevent overheating of the coil. When the hindrance is removed, the fan
restarts automatically.
34. Precautions regarding dropping and rollover
Avoid impact of dropping or rollover to the fan.Precision ball bearings are used
for the bearing of the fan.
When an impact is added, the bearing suffers damage, and may lead tothe degradation of product performance, such as extraordinary noise andshortening of life expectancy. Follow the next conditions with extra caution
when handling transportation and installation.
・The dropping limitation of the product stand-alone: The maximum limit ofdropping height is 3 cm.
・The external force limitation of the product stand-alone: A weight of 100
g dropped from a height of 3 cm above the product stand-alone is the
maximum limit. A force of 5 kgf to the fan blade is the maximum limit.
・The dropping limitation in a packaged condition: The maximum limit ofdropping height is 30 cm.

In the case of installation, please be careful of the direction of airflow.
Please refer to the catalog for details of model numbers and otherdescriptions, and apply the correct combination.
[2] Filter kit
・A filter kit keeps air in the chassis clean by filtering dust from external air
when using suction cooling. The filter kit is attached with screws throughthe fan frame mounting holes along with a finger guard. Some performancevalues (airflow & static pressure) of the fan motor degrade when a filter kit is
attached.
・Resin filter kits are composed of 3 components: a guard, a filter, and a cover.

It is delivered as a finished product, decreasing assembly time for mounting. It
can be mounted by inserting screws through the apertures of the cover.
・The filter and cover can easily be attached or removed from the guard. Thereis no need for fan removal when performing filter maintenance.
・Ensure fan is disconnected from power source before exchanging filter.
・Operating temperature limit is between -10℃ to +60℃ . (non condensing)・The filter will deteriorate with age, and the level of deterioration will varywith usage conditions. Please be aware that the filter has a greater tendency
to deteriorate under high temperatures and humidity. For long-term storage,
please store within a temperature range of +10 ℃ to +30 ℃ , and a humidity
range of 20% to 65%. Product lifespan is two years, including time in storage.
・Cooling ability decreases with filter contamination from clogging. Filter
replacement is recommended after approximately six months of usage.
