4.1.1
Remove the packaging/protection from one Radiant Tube and ensure it is clear internally. The appliance
should be assembled prior to being suspended and due consideration must be given to the means by which
the appliance is to be safely raised into position.
4.1.2
Place the Radiant Tube on trestles, providing 150mm minimum cleara nce above the floor and assemble
the three Hanger Brackets to the Radiant tube using one U bolt per bracket (fastening pack) and position
along the Radiant Tubes as shown in Fig. 9. Ensure that the welded seam of the tube is in contact with the
Hanger Bracket, i.e. facing away from the reflector. Tighten the nuts sufficiently to retain the Hanger
Brackets. Do not overtighten.
IMPORTANT
: Failure to assemble the Radiant Tube with its welded seam facing away from the reflector
will void the manufacturers warranty.
4.1.3
Place a Torctite Coupling over one end of the Radiant Tube ensuring that it engages fully up to the stop.
Assemble a Control Box to the Radiant Tube ensuring that it engages fully into the Torctite Coupling (up to
the stop) and is positioned vertically with the door latch uppermost (see Fig. 5). Tighten the screws of the
Torctite Coupling to secure the Control Box to the Radiant Tube, taking care to support the Control Box in
line with the axis of the tube.
NOTE
: Tighten the Torctite Coupling screws alternately whilst continually checking for slackness of the
joint.
4.1.4
Place the two Reflector Panels onto the Hanger Brackets and position to provide a 50mm overlap,
arranged equally about the inner Hanger Bracket (see Fig 9.). Clamp the two Reflector Panels to the inner
Hanger Bracket using two Retainers and M6 setscrews and washers (fastening pack). Screw the
remaining (4) Retainers to the two outer Hanger Brackets to provide location for the Reflector Panel ends
as shown in Fig. 9.
NOTE
: The outer ends of the Reflector Panels will be free to move and compensate for expansion and
contraction caused by temperature variation.
4.1.5
Position one Reflector End Panel over the Radiant Tube and into one end of the Reflector Panels, with the
end panel flange flush with the end of the Reflector Panel. Secure the Reflector End Panel to the Reflector
Panel by use of six 'U' type speed clips provided (fastening pack): as shown in Fig. 9.
Repeat the procedure to attach the second Reflector End Panel to the opposite end of the reflector.
4.1.6
Construct the second section of the appliance by again following procedures 4.1.1 to 4.1.5 above.
4.1.7
The two sections of the appliance should now be raised and suspended from previously fixed chain s or
drop rods as detailed in Section 3.1., at suspension points indicated in Fig. 9 & 10. Rope or webbing
should be used when lifting from above. If using a forklift to position the appliance, ensure that it is
balanced on the forks prior to lifting.
