CB series blower is equipped with one of two methods to prevent burning the blower as a result of abnormal heating
Impedence Protection
( CB 100836)
The blowers are designed with higher impedence in the motor windings so that even if the motor locks, the increase
in current is kept down hence the temperature does not rise beyond certain constant level.
Thermal protection (CB121255, Cb161270, )
When the blower reaches a predetermined temperature, the internal thermal protector is activated and the blower
is stopped.
With the automatic resume feature, the blower automatically begins operation again as soon as the blower
temperature falls to a certain level. Always turn the power off before performing inspections.

A mounting bracket matching the diameter of the
motor casing
is available.
With this mounting
bracket, a blower can be secured to the equipment
by using the motor casing section of the blower.
While installing a blower, be sure to use a spacer so
that the impeller casing does not touch the surface to which
the mounting bracket is secured.

4. 2 Mounting the capacitor
(For only single-phase types)
Before mounting
the capacitor,
check the
capacitance of the capacitor provided, matches the
capacitance indicated on the blower’s nameplate.
Use clamp to mount the capacitor

Note :
Install the capacitor at least 10cm, away from
the motor as the capacitor life span may be shorten
due to heat from the blower.
