ELECTRICAL CONNECTION
NOTE: Junction box supplied is suitable for internal use and below roof installation
• Cut the roof fl ashing on the 240/255 marking and fi t to the rigid duct before commencing (see separate
installation sheet detailing this).
• For below roof terminations the motor lead exit hole should be as far down the rigid duct as is practical –
allow enough lead to protrude from the duct as is required for termination. After fi tting the roof fl ashing, drill
an 8mm hole at a suitable point in the rigid duct and fi t the supplied rubber grommet. The motor lead can
then be passed through the grommet to the outside of the rigid duct.
• The assembly can now be placed in position in the roof penetration (see instructions on page 3). Once the
assembly has been fastened to the roof by the roof fl ashing fastening procedure, the electrical connections
can be made. The junction box can be fastened to the rigid duct if necessary.
Junction box is supplied for the following cowls and kits with an inline centrifugal fan:
FAN2120 / FAN2122
Junction box is supplied for the following cowls and kits with an inline high performance
centrifugal fan:
FAN2121 / FAN2123
• You may fi nd it more convenient to pull the whole assembly down as far as possible in the roof fl ashing
to carry out the terminations (Fig 1). Once completed, the assembly can then be pushed back up through the
Dektite. Ensure that a visual check is made above the roof afterwards to check that the roof fl ashing is sealing
correctly around the rigid duct (Fig 2). Once the terminations are completed the rigid duct can then be
fastened to a rafter or purlin with the supplied clamp for rigidity. Ducting connections can then be made.
• Precautions must be taken to avoid the back-fl ow of gases into the room from the open fl ue of gas or other
fuel-burning appliances.
