  • Page 6 Contents of plastic bag contained in parts box. The contents of this packet are to suit a Elite 900 fan. Cardiffair black powder coated 900 Elite fan. These fans also come in stainless steel and galvanised applications. Fan should be placed on a table for ease of assembly, at a comfortable working height.

  • Page 7: Motor Mounting Plate Bend Bar

    Place the fan shroud over the top of the fan on the table. Photos below show the motor mounting plate holes on the bend bar. When assembling this fan you should always start with the motor mounting plate bend bar and work around from there. Of the 4 bend bars, you should have one that has 3 holes in the side closest to the foot of the bend bars.

  • Page 8: Bend Bar

    This picture shows the bend bars and fan in position around the fan shroud. There is no particular start point to lay the bend bars out but what you have to take care in, is that the bars have a running sequence. Start with the motor mounting plate bend bar and place it at one of the 4 smaller holes punched around the fan shroud and lay it over the fan in the middle.
  • Page 9 The smallest bolt, a washer and a nylock nut are used to locate the bend bars into place. A 13mm spanner on both the nut and washer is generally all that is needed. Place the square piece of nylon (spacer) over the hole on the fan shroud and underneath the foot of the bend bar.
  • Page 10 Repeat the same process for all 4 bend bars taking care to over-lap the left hands of each bend bar over the shaft of the bend bar on the right. A good way to ensure assembly goes right every time, is to start with the mounting plate bend bar first, be sure that the bearing housing bend bars are opposite one another parallel to the motor mounting plate bend bar.
  • Page 11 The next step is to locate the bearing housing into place. Remove all of the rust inhibitor on the shaft of the bearing housing. The easiest way to do this is to wipe the shaft down with some WD40 and some sand paper.
  • Page 12 Once the fan is located on the shaft then insert the bearing housing bolts Push the bolts through from the inside of the square into the bend bars. formed by the bend bars to the outside. Place a washer and a nylock nut on each bolt.
  • Page 13 The next step in the assembly process is to insert a cardboard square (there are 3 or 4 provided in the carton to prevent scratching) between the fan and the fan shroud. While all the nylock nuts have not been tightened, the use of the cardboard insert assists in the central alignment of the fan in the fan shroud.

  • Page 14: Fan Tightening

    Fan tightening sequence. A tightening sequence is in place to assist the cardboard spacers in preventing the fan from fouling the shroud. It is important that this sequence is done properly as the fan will foul the shroud if not done correctly. To tighten the bolts in the correct order, start at the bearing housing bolts (marked as indicated) and tighten the diagonals one at a time.
  • Page 15 Then start with the diagonals on the bend bars, repeating the same process as before. What you are actually doing is working from the inside out, tightening the bearing housing first, then the bend bars and finally the fan shroud. The last bolts to be tightened are the fan shroud bolts.
  • Page 16 Once the fan has been fully tightened up you can test the fan for fouling by spinning the fan on the table. As you can see from the picture the fan spins quite freely with no interference at all. You are now three quarters away from completing a fan assembly.
  • Page 17 The only difference is the 1070 unit has the larger nuts behind the mounting plate and the mounting holes used are closest to the edge of the bracket 900 FAN UNIT:- NO SPACERS 1070 FAN UNIT : HAS SPACERS Fan Assembly...
  • Page 18 All materials required to install a Cardiffair System correctly in a Domestic, Commercial or Industrial application are to be supplied by the installer. The remaining 12 rubbers grommets (rubber dampers) are pressed into place around the fan shroud. There are 12 holes in the shroud and every hole will have a vibration damper.

  • Page 22: Tools Required

    Note: The installation of this motor is the same for all types of motors that can be fitted to a Cardiffair Unit. For the purpose of this manual we are using a 425W motor just for instruction purposes.

  • Page 23: Mount Plate

    The location of the motor onto the mount plate is determined by the size of the motor. The mount plate has slotted grooves (6 in total) to accommodate various motor sizes. The mount plate is the same for both the 900 and 1070 units.
  • Page 24 You can hold the motor and place another flat washer, spring washer and nut onto the bolt that has been fed through the mounting plate. Once all the nuts and washers have been loosely fastened into place, slide the motor pulley onto the motor shaft and run the V belt over the fan and motor pullies.
  • Page 25 While you are still applying tension to the V belt use a screwdriver to scribe a mark on the motor mounting plate. The V belt does not need to be under too much tension. When you have scribed the mark on the mounting plate, remove the V belt from the pullies and carefully slide the motor 3 to 5mm past the mark that you have scribed with your screwdriver on the mounting plate.
  • Page 26 (See picture below). All of the motors that are used by Cardiffair are installed in this fashion. The motor capacity varies from 350W to 800W. The motors can also be single phase (240V) or three phase (415V).

  • Page 27: Control Box

    The contents of the box pictured below is required to connect the 425W variable speed motor and the MK III Variable Speed Control Box. Note the MKIII Variable Speed Control Box can only be used with a variable speed 240V motor. List of contents out of the above mentioned box.
  • Page 28 Now that the 425W motor is on the fan, remove the motor pulley and slide the speed sensor disc down the motor shaft. You may need to use some WD40 to assist in sliding the disc in place. Use the 3mm Allen Head Spanner to tighten up the grub screw in the sensor disc.
  • Page 29 Take the speed sensor coil, speed sensor mounting bracket, the screws and the washers and fix them together like the picture below shows. Then unscrew the speed sensor coil from the speed sensor bracket. What you are doing is creating a thread in the predrilled holes so that it is easier to locate and fix the speed sensor bracket to the motor mounting bracket.
  • Page 30 Now that you have run the screws into the speed sensor mounting bracket remove the screws and slide the mounting bracket underneath. Slide the spring washers over the screws provided and fix the speed sensor pick up coil in place. Note: there should be spare screws.

  • Page 31: Motor Pulley

    Adjusting the air gap between the sensor disc and the pick up coil as the two foul when the motor is turning. The air gap between the sensor disc and the pick up coil is not critical. Once this step has been done slide the motor pulley back down into place on top of the speed sensor disc.

  • Page 32: Fan Unit

    The picture below shows the fan unit with the motor and speed sensor kit assembled and ready for use. Now that the fan and motor are assembled and in place, select a suitable area for the MKIII control box to be mounted into place. Depending on the installation you can screw fix the MKIII control box anywhere so long as the motor lead and the 3 pin GPO have enough length in them to allow for easy connection.This does not apply to hard wired installations.

  • Page 33: Motor Capacitor

    For the MKIII control box units it is best to enclose the motor capacitor and connection plug in a junction box. The motor plug and capacitor will fit neatly into the junction box. You will need to cut ONE end out of the junction box so that the motor plug cord can come out.
  • Page 34 As you can see in this picture the factory settings will be / JMP1 has been set in position 2 / and JMP3 is in position 1. This tells us that the control box is setup to run the Cardiffair 900 unit.
  • Page 35 Double check that all connections are secure and place the lid back on the top of the control box. Plugged in Louvre Actuator neg and pos shown. Complete! You have now successfully completed the installation for a Cardiffair Motor Unit. Motor Installation...

The end with the hole is attached to the Louvre Panel Connecting Bar. There is a pre drilled hole on the connecting bar for the correct position of the Louvre Panel when the Louvre Panel is open and closed.
  • Page 39 Once the connecting arm is in place, attach the other end of the arm to the Louvre Actuator Motor Drive Arm. Make sure that the screw and nut are tight, then simply slide the screw on the arm through the hole in the Drive Arm and place the nylock nut on the end of the screw and tighten up.
