DESIGN AND OPERATING PRINCIPLE

CBF LP 110 DC, CBF LP 110 DC TH/TP

CBF LP 110 DC Light, CBF LP 110 DC Light TH/TP

The fan casing is made of galvanized steel. The fan casing includes an exhaust spigot with a back draft damper to prevent air back flow.
The terminal box comprises the terminals for wiring of the fan and is attached to the fan casing. The decorative grille is fixed to the casing via the springs inserted in the hooks. The front panel is fixed via the grille slots. An electric motor with a centrifugal impeller with forward curved blades is fastened inside of the casing.

The fan is equipped with a timer. After an external switch, e.g. a light switch is turned on, the fan turns on or switches to high speed after countdown of a set turn-on delay time, adjustable from 0 to 3 minutes. After the fan is turned off it keeps running for a set turn-off delay time, adjustable from 1 to 90 minutes and then reverts to the initial operation status.
Depending on the model, the fan is equipped with a light source (LED-lamp), humidity or motion sensors.

Motion sensor (TP)
Upon activation of the motion sensor the fan is turned on and switches to high speed. After no more motion is detected the fan keeps operating for a set turn-off delay time period, adjustable from 1 to 90 minutes, and returns to its original state.

Humidity sensor (TH)
If the set humidity level in the room is exceeded from 50 % to 90 %, the fan turns on or switches to high speed. As the indoor humidity  level drops down the fan keeps operating for a set turn-off delay time period, adjustable from 1 to 90 minutes, and then returns to its original state.

MOUNTING AND SET-UP

READ THE USER’S MANUAL BEFORE INSTALLING THE UNIT.

The fan is a component part and is not designed for stand-alone operation.
The fan is designed for ceiling mounting and installation in the space between the joists (the distance between the joists is from 270 mm to 470 mm) using a removable bracket or fixation holes in the fan casing.
The fan installation location must comply with local building codes for this type of product.
Check the fan for mechanical damages prior to mounting.
Before mounting make sure the casing does not contain any foreign objects (e.g. foil, paper).
While installing the unit ensure convenient access for subsequent maintenance and repair.
The minimum distance between the unit and the ceiling should be at least 5 mm.

MOUNTING SEQUENCE

1. Install the fan in the space between the joists using the screws.
   

2. Connect the fan of a required diameter.
   Vertical mounting to joists on the wall is allowed.

3. Connect the LED lamps (included in the delivery set) for the Light models. Optional: connect a humidity or motion sensor (sold separately).
   For models with the Light option, plug the power connector of the LED lamp into the appropriate socket in the fan terminal box casing.
   For models with the option of connecting TH (humidity) or TP (motion) sensors remove the protective cap from the grille before installing the decorative grille. Route the connector of the TH or TP sensor through the opening in the grille and connect it to the corresponding connector on the control unit. Fix the sensor in the grille opening and cover the opening with a protective cap.
   
   

4. . Fix the decorative grille to the fan casing using the hooks on the casing.

CONNECTION TO POWER MAINS

POWER OFF THE POWER SUPPLY PRIOR TO ANY OPERATIONS WITH THE UNIT.
THE UNIT MUST BE CONNECTED TO POWER SUPPLY BY A QUALIFIED ELECTRICIAN.
THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE GIVEN ON THE MANUFACTURER’S LABEL

ANY TAMPERING WITH THE INTERNAL CONNECTIONS IS PROHIBITED AND WILL VOID THE WARRANTY.

The fan is rated for connection to single-phase AC 100-240 V 50/60 Hz power mains.
The fan is connected to power mains using insulated, durable and heat- resistant conductors (cable, wires) through the QF automatic circuit breaker with a magnetic trip built into the stationary wiring. The position of the automatic circuit breaker must ensure free access for quick power-off of the unit.

ACCESS TO THE TERMINAL BOX FOR CONNECTING THE FAN TO POWER MAINS

Remove the decorative grille.
For accessing the connection terminals loosen the screw on the terminal box lid and take the lid off.

Remove the protective cap and install the cable gland.

CONTROL

MICROPROCESSOR CONTROL UNIT WITH INDICATION

The operation of the fan with a DC motor is controlled by a microprocessor control unit. An indicator, control buttons and two connectors for connecting a humidity sensor and a motion sensor are located on the front panel of the control unit.

After the fan is connected to power supply, the indicator displays for two seconds. After that the light indicator goes off and the fan starts operating in set mode. Once the button is pressed the indicator displays the turn-off delay timer setting , the first Setup menu entry. Use buttons to navigate in the Setup menu. Press , to select a current entry in the Setup menu. After that the indicator displays the selected parameter value (e.g., turn-off delay timer setting). Use to change the value. Press to come back to the Setup menu. If no button is pressed for 60 seconds, the indicator goes down.

Example
The indicator displays . Once the button is pressed, the Setup menu list goes one position down and the symbol is displayed (refer to the Setup menu). Once the button is pressed, the indicator displays the turn-on delay timer setting, which can be edited with the buttons and . Once the button is pressed again, the Setup menu is displayed again and the edited value is saved.

To reset the menu to the factory settings , press and hold and synchronously. In 5 seconds the indicator displays , and goes off.
The fan keeps running in a regular operation mode with the factory settings

INDICATOR SYMBOLS OF THE MICROPROCESSOR CONTROL UNIT

turn-off delay timer adjustable from 1 to 90 minutes (default setting 15 minutes).
 – turn-on delay timer adjustable from 0 to 180 seconds with the increment of 10 seconds (default setting 0).
– humidity setpoint adjustable from 50 % up to 90 % (default setting 75 %).
– access to submenu of the fan operation mode.

Operation mode  – the fan operates without any activation signal from the switch, humidity or motion sensor.
Operation mode – the fan operates with activation signal from the switch, humidity or motion sensor.
 – back to the upper setup menu level.

Once the switch is turned on or the humidity or motion sensor is activated, the fan switches from the mode to the mode .
After a signal is no more received from the sensor in case of the indoor humidity normalization, or no  more motion is detected in case of the fan shutdown, the fan keeps running for a set turn-off delay time and then switches from the mode to the mode .

– the fan is turned off.
«60», «70», «80», «90», «100», «110» – the fan operates in the mode of maintaining a constant air flow with a given value of the air flow rate displayed in cubic feet per minute (CFM).

Example 1
– with these settings, the fan will constantly maintain the air flow rate of 60 CFM. Once the switch is turned on or a sensor is activated, the fan will operate at maximum possible performance. This setting is factory set and is the default setting for fans with a maximum air flow of 110 CFM. For the fans with a maximum air flow – 150 CFM

Example 2
– with these settings, the fan will be constantly turned off. Once the switch is turned on or a sensor is activated, the fan will switch to maintain the air flow rate of 90 CFM.
By changing the parameters and in this way, you can select the desired fan mode.
