HARS series
2-5-2 Ventilation
The front and rear of the power supply unit are equipped with air intake and exhaust ports for cooling.
Provide enough space around these ports to ensure sufficient air circulation, and please use the
product in a well-ventilated area with a space of 30cm or more.
Promptly remove any dust that accumulates in the intake port.
If dust accumulates in the intake port, it will interfere with the cooling of the unit and
lead to breakdown.
2-5-3 Fan Replacement
The fan in this power supply has a limited service life. As it becomes worn and deteriorates
with use, its operation might become unstable. Note that the service life of the fan will vary
greatly depending on the usage environment (temperature, humidity and dust). In order to
use this power supply for a long time, it is necessary to replace the fan at regular intervals.
Please contact Matsusada Precision for assistance in replacing the fan. (A separate repair
fee is required to replace the fan. Do not replace the fan by yourself as it may cuase electric
shock.)
