INSTALLATION AND SET-UP

READ THE USER’S MANUAL BEFORE INSTALLING THE UNIT

The air motion in the system must be as shown with the pointer of the fan casing. In the case of the vertical installation, the intake spigot must be protected with a ventilation hood. To attain the best performance of the fan and to minimize turbulence-induced air pressure losses while mounting, connect straight air duct sections to the fan spigots on both sides of the fan.

Minimum straight air duct length:

• equal to 1 air duct diameter on the intake side
• equal to 3 air duct diameters on the outlet side

If the air ducts are too short or not connected at any spigot, protect the fan’s inner parts from the ingress of foreign objects by installing a protecting grille or other protecting device with a mesh width not more than 12.5 mm to prevent uncontrollable access to the fans. While installing the fan ensure convenient access for subsequent maintenance and repair. The unit must be mounted on a an even wall.

INSTALLATION STEPS

• Disconnect the fan from the power supply
• Install the fixing brackets
• Learn the fan against the installation place and mark the fastening holes
• Drill the holes and insert the expansion anchors
• Fix the fan
• Connect air ducts

CONNECTION TO POWER MAINS

DISCONNECT THE POWER SUPPLY BEFORE ANY OPERATIONS WITH THE UNIT. CONNECTION OF THE UNIT TO POWER MAINS IS ALLOWED BY A QUALIFIED ELECTRICIAN WITH A WORK PERMIT FOR ELECTRIC UNITS UP TO 1000 V AFTER CAREFUL READING OF THE PRESENT USER’S MANUAL. 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 unit is rated for connection to single-phase AC 230 V/ 50 (60) Hz power mains. For electric installations use insulated durable heat-resistant conductors (cables, wires) with a minimum wire cross-section of 0.75 mm2.
• The conductor cross-section value must be selected depending on the wire type, maximum permissible heating temperature, insulation, length, and installation method.
• Connect the fan to power mains via an external automatic circuit breaker installed at the power input and integrated into the house cabling to open the circuit in case of a short circuit or overload.
• The circuit breaker location must provide quick access for emergency shutdown of the fan.
• The fan is connected to the terminal box attached to the fan casing in compliance with the wiring diagram and designation of terminals.
• The terminal designation is shown on the sticker attached to the internal wall of the terminal block.

ACCESS TO THE TERMINAL BOX

The fan can be equipped with a power cord with an IEC C14 connector. The fan is rated for continuous operation.

Electronics operation algorithm

• The G1/GT1/GS1 fan is equipped with an electronic module TSC (speed controller with an electronic thermostat) for automatic speed control (air flow) depending on the air temperature.

The terminal compartment incorporates 2 control knobs:

• presetting speed
• setting electric thermostat threshold value

The fan is equipped with two indicators:

• temperature sensor indicator (hereinafter referred to as TSI) – yellow color
• motor control indicator (hereinafter referred to as MCI) – green/red color

When the fan turns on, the TSI indicates the unit operation algorithm:

• one pulse – G1
• two pulses – GT1
• three pulses – GS1

The MCI lights up in green when the motor rotates and in red when it stops (or rotates very slowly). To set the thermostat threshold, rotate the thermostat control knob clockwise to increase or counter-clockwise to decrease the temperature set point. To set the fan speed (air flow), rotate the speed control knob in the same way.

• G1: In this case, fan speed switching operations are rare. The TSI lights up and the fan switches to the maximum speed as the room air temperature exceeds the set point. As the air temperature drops 2 °C below the set point or if the initial temperature is below the set point, the TSI goes out and the fan operates with the set speed.
• GT1: The speed switching operations are more frequent as compared to the temperature-based functioning logic (G1), but one-speed interval continues for at least 5 minutes. The TSI lights up and the fan switches to the maximum speed as the room air temperature exceeds the set point. As the air temperature drops down below the set point, the TSI starts blinking, the timer starts a 5-minute countdown and then the fan switches to the set lower speed and the TSI goes out.
• GS1: The fan starts only at a certain air temperature. The TSI lights up and the fan switches to the set speed as the room air temperature exceeds the set point. As the air temperature drops 2 °C below the set point or if the initial temperature is below the set point, the TSI goes out and the fan turns off.

TECHNICAL MAINTENANCE

DISCONNECT THE UNIT FROM THE POWER SUPPLY BEFORE ANY MAINTENANCE OPERATIONS! MAKE SURE THE UNIT IS DISCONNECTED FROM THE POWER MAINS BEFORE REMOVING THE PROTECTION.

• Technical maintenance means regular cleaning of the unit surfaces of dust. Use a soft brush or compressed air to remove dust.
• Clean the impeller blades at least every 6 months.
• Installation of an air filter prolongs the interval between the cleaning, to perform the cleaning first remove the screws and the fan cover.
• Wipe the impeller blades with a cloth wetted in a mild detergent solution. Avoid water dripping on the electric motor!
• After cleaning the impeller install the cover and tighten the screws.
