5. Maintenance inspection
Test button
This is such a test button that confirms whether
the breaker (NFB) of this machine operates
normally at the time of overheat. One time in a
month, please continue to push the button for
several seconds in operation stoppage condition
(Electricity is flowing). And, please confirm the
illumination of the OVERHEAT lamp, operation
display of overheat P.9), and trip action of the
breaker (NFB) of this machine. (TSK-18 is only
the illumination of the overheat lamp and display
of the overheat operation.)
After confirmation, please turn OFF the source
power supply (factory power supply) and breaker
(NFB) of this machine at first. And please turn
ON once again. (TSK-18 is only input of the
factory power supply.)
Test button
Inspection of the inlet wire net and filter
The wire net is equipped to the inlet of the hot-air generator. (Demi-filter is standard equipped to a part of
hot-air generator.) Please inspect the wire net and filter of the inlet always, and please clean periodically.
Heater case inside becomes the abnormal high temp. and overheat or temp. warning is occured if the wire
net and filter are clogged.
Storage
Please pay attention to the condensation sufficiently in the case that the hot-air generator is stored long
time. Condensation occurs by the temp. of storage atmosphere drops in the winter season. Hot-air generator
becomes freezing condition if this machine is stored in the condition that the condensation occurred, and it
becomes the cause of the malfunction of an electricity part.
Individual inspection
I recommend that is carried out the individual inspection in the case that the use period exceeded 10 years
to have this machine used more safely.
【
Item of the individual inspection
】
Measurement of the insulation resistance value
Measurement of the heater current value
Increase bundle inspection of each terminal unit
Other inspection by eyes
Foreign substance mixing inspection and cleaning inside the controller
Foreign substance mixing inspection and cleaning inside this machine and inlet
Action of the electricity part and generation inspection
Please ask to the adjacent electricity businessman about the individual inspection.
Attention
Please do not carry out the insulation resistance voltage test of this machine. (It gets finished
enforcement at the time of shipment.) It becomes the cause of malfunction.
About the electricity fire
Operation condition of the front where stops automatically is started by the input of the primary
power supply in one second after the hot-air generator stopped instantaneously by power failure
etc. We recommend the establishment of the device that blocks the primary power supply to
electricity fire prevention at the time of the disaster of earthquake etc.
