1.Safety requirements: Warning
1.1 The maximum permissible ambient and air temperature at the intake is + 40°c.
1.2 All the works of transportation, installation, maintenance and trouble shooting must
be executed by a responsible, qualified personnel.
1.3 This device must be set up according to this instruction manual.
1.4 The grounding wire must be connected well accordingly.
1.5 The lead wires as a conductor to the power supply should be properly sized and have
strain relief to the wires at the connection terminals. If this is failed , electric shock and
fire will be possible.
1.6 While rotating , human body must be kept away from the rotating portions such as
the cooling fan and do not reach into the device through the intake or outlet.
1.7 Once the power electricity was interrupted , the power switch must be turned Off
immediately .
1.8 If the device does not reach its rated speed in 6 seconds from the power switch
turned on , please turn off the power immediately and check it carefully.
1.9 The power supply must be turned off before moving, maintaining , or repairing this
device. Please note that , due to rotating inertia, the device may continue running
several minutes after power turned off .
1.10 These devices are only used to handle or convey dust-free air, non-combustible,
non-corrosive and non-explosive gases, vapors.
1.11 The intake must be properly sited and covered so that no dirt or solid particles can
be sucked in .
1.12 Pilot type of thermal protector is provided. This protector should be externally
connected with a magnetic switch which is used to control the power imput ON/OFF.
1.13 This device is designed for continuous operation , in case of non-continuous
running or high ambient temperature, checking suitability(maximum permissible
temperature)with the representatives of manufacturer.

2．Installation
2.1 Installation precautions:
2.2.1 To avoid vibration, the unit must be mounted on a rigid base.
2.2.2 Any flammable materials must be kept away from the unit.
2.2.3 Air and gases should be filtered before entering the intake by an intake or
inline filter.
2.2 Electric Connection:
WARNING: No connecting work is allowed before the electric power is
disconnected.

4
2.2.1 Choose the correct circuit breaker to match the motor’s rated current.
2.2.2 We recommended when using the magnetic switch, the setting value of electric
current is the motor’s rated current of 0.91 times.
2.2.3 Thermal protectors connection:
2.2.4 The ground wire must be connected to the grounding terminal.
2.2.5 The lead wires must be connected according to the diagram attached on the
terminal box.

3 Operation:
3.1 These devices must be rotated as the “Arrow”direction marked on the casing.
3.2 For three phase, changing direction can be done by exchanging any two of the
connected wires.
3.3 These devices should be operated with the rated current and pressure within the
permitted range listed in the nameplate of the motor.
3.4 After wiring has been completed, reconfirm the rotation direction is same as arrow
marked on the casing.
3.5 Changing the outlet direction
3.5.1 If the discharge direction is not requested , our standard model ( FDC-005A-7W
