Replacing Fan Motor
The lifespan of the fan motor when used at the rated output power is approximately 60,000 hours in a 25℃
temperature environment. If air flow decreases, there may be trash or dust stuck. Please first clean the air filter.
If air flow does not improve after cleaning or if noises are emitting from the fan, the fan motor should be replace.
1) Ready the new fan motor (connectors attached).
(Contact the Takasago sales department for place of purchase.)
2) Disconnect the power cable from the input power source.
(Or, in the case of the ZX-S-400H, 800H types, remove the input power cable from the rear inlet connector.)
3) Wait for at least 3 minutes for the internal voltage to decrease.
4) Remove and replace the fan motor as shown below.
Replacing Fan Motor
① Remove the four M3 screws attached to the fan motor. Pull out the fan motor.
② Disconnect the power wire connector (black) attached to the circuit board.
③ Connect the new fan motor’s connector. Insert the fan motor while being careful not to pinch the wire
between the fan motor and rear panel and screw in the four screws.
④ Connect to the input power supply and turn the POWER switch ON. Verify that the fan rotates.
Fan revolution responses to and is controlled by the output power and output current.
Therefore, if the output power or output current is low, air flow will decrease.
(The fan will rotate at a low speed if no load is attached.)
Replacement can be done by the owner. For this, a plus screwdriver for a 3mm screw is required.
