1. Precautions
1.1 Precautions for Installation
Do not use in a place where there is flammable gas and / or corrosive gas. Connect the ground wire
to the ground terminal inside the terminal box (if connected).
When installing the blower into your equipment, ensure that the motor lead wires are fixed and do
not move.
In addition, do not apply any pressure to these lead wires.
Installation must be performed by a qualified installer.
1.2 Precautions for Operation
Always turn off power to thermally protected blower before conducting checks or performing work
on the blower.
These types of blowers will restart automatically when blower temperature falls below a certain level.
0
The enclosure temperature of this blower can exceed 70C (depending on operating conditions.).
In case blower is accessible during operation, please attach the following warning label so that it
is clearly visible.
Do not touch the blower blades (impeller) when the blower is in operation.

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.

5. Overheat P
rotection
www.fhpgearedmotors.com
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.
4.1 Mounting the blower
Use of mounting bracket (Option)
Air flow Direcion
Mounting on a Plate
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
Air flow
Rotation
Plate
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.
