Maintenance and inspection
It is recommended that the product be checked for any abnormal vibrations, noises, and proper insulation
every three months.
Bearing lubrication is not required, as sealed type ball bearing is used for the motor bearing. Grease
life is generally one year, although it varies depending on the operating environment.

Switch contact failure
When a wire is not turned on electrically due to power
wire interruption or poor switch contact, etc., the
motor will operate in single-phase, resulting in motor
burnout.
(2) Rotational direction
Check whether the rotational
direction matches the rotation arrow
on the nameplate.
If the rotation is in the opposite direction, replace
two power wires.
(3) Operating static
pressure and electric
current
Use a pressure meter and ammeter to
check if the operating static pressure
and electric current are below the
maximum operating static pressure
and current.
When the operating static pressure exceeds the
maximum value, create a bypass hole to release the air.
(4) Operating status
Check whether the Blower generates
abnormal vibrations or noise.
Please contact Showa Denki.
