  • Page 3: Introduction

    Exhaust fans are made according to the current required standards on labor safety. EXAFAN declines any responsibility for any eventual harm to people and damage to byproducts due to the non – authorized use of the ventilation system EX36-50, due to incorrect assembly of the mechanical or electric parts, or due to the elimination or manipulation of the protection devices.

  • Page 4: Safety During The Manipulation And Transportation

    Check the conditions of the material at its reception. In case of any damage, you should inform the transportation agency about it by means of a written document, as well as immediately communicate it to the EXAFAN S.A.U. company. In case of a not immediate installation, we recommend to store it in a clean and dry place, free of dust, of any vibration, gas and corrosive agents, with an air relative humidity not exceeding 60%.
  • Page 5 Regarding the right dimensioning of the supply cables, maneuver and protection devices, we must consider the nominal motor current, the service factor and the length of the cables, among others. The cable inlets not used in the connection box should be covered with locking systems in order to guarantee the protection degree indicated on the features panel.

  • Page 6: Safety During The Maintenance

    Defects in the connections. Annual An authorized technical service by the Exafan Company S.A.U. must get in charge of the motor dismantling process during the warranty period. Every motor manipulation must be made carefully so as not to damage the bearings.

  • Page 7: Assembly Of The Safety Pins

    02.05. Assembly of the safety pins On the sides of the fan, you may find the safety pins (one on each side) enabling to block the fan shutter in open position. This function is especially useful when cleaning the fan, or simply in order to let the sunlight get through the fan in air inlet mode.

  • Page 8: Wrong Use

    High Flow Fan EX 36-50 V4 C6 ONCE YOU HAVE MADE THESE REQUIRED TASKS WHILE THE SHUTTER IS BLOCKED, AND BEFORE PLUG THE FAN TO THE ELECTRIC POWER SUPPLY AGAIN, DO NOT FORGET TO TAKE OUT THE SAFET PINS. THESE SAFETY PINS ARE ONLY USED TO KEEP THE SHUTTER OPEN: THEY MUST NOT BE PLACED WITH THE SHUTTER CLOSED SINCE THIS COULD MAKE THE FAN WORK INCORRECTLY.

During the installation of the fan, we must bear in mind the distance from the wall till the fan edge. There are two lids on the sides of the fan.
  • Page 65 In case of fixing the fans outside the building wall, some strong supports leaning on the entire fan surface are required. The correct thing to do is putting the fans over a small wall so that the fan surface lies on it perfectly. (Fig.140).
  • Page 66 For fans that are installed at a height less than 2.7 m from the ground (with reference to bottom / or / base of the fan), will be necessary to install indoor and outdoor protection grid in order to avoid uncontrolled entrapment between fan blades. This protection grid will be supplied by EXAFAN on the request and additional costs will be applied.
