4.2.1
Remove the packaging/protection from two Radiant Tubes and ensure that they are clear internally. It is
recommended that the appliance is suspended in sections which are joined by the use of a Torctite
Coupling once in position.
4.2.2
Place two Radiant Tubes on trestles, providing 150mm minimum clearance above the floor and assemble
two Hanger Brackets to each of the Radiant Tubes using one U bolt per bracket (from fastenings pack) and
position along the Radiant Tubes as shown in Fig. 11 Ensure that the welded seam of the tubes 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 Tubes with their welded seam facing away from the reflector
will void the manufactures warranty.
4.2.3
Place one Torctite Coupling over the end of the relevant Radiant Tube ensuring that it engages fully up to
the stop. Assemble the 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.
4.2.4
The two sections should now be raised and suspended from previously fixed chains or drop rods as
detailed in Section 3.1, at suspension points indicated in Fig. 11 & 12. Rope or webbing should be used
when lifting from above. If using a forklift to position the appliance sections, ensure that they are balanced
on the forks prior to lifting.
Fig. 12
4.2.5
Place a Torctite Coupling over the open end of one Radiant Tube ensuring that it engages fully, up to the
stop. Assemble the second Radiant Tube into the Torctite Coupling ensuring that it engages fully, (up to
the stop), with the Hanger Brackets aligned with those of the first Radiant Tube section
(see Fig. 11). Tighten the screws of the Torctite Coupling to secure the two sections of Radiant Tube to
one another, taking care to maintain the tubes in a straight line.
NOTE
: Tighten the Torctite Coupling screws alternately whilst continually checking for slackness of the
joint.
4.2.6
Place two of the Reflector Panels onto the Hanger Brackets and position their outer edges such that they
overhang the outer Hanger Bracket by 80mm (see Fig. 11). Place the third Reflector Panel over the two
previously positioned Reflector Panels to provide a 50mm overlap at each end. Clamp the first and second
Reflector Panels, where they overlap, to the second Hanger Bracket, (from Control Box) using two retainers
and M6 setscrews and washers (fastenings pack). Secure the outer end of the centre Reflector Panel to
the Reflector Panel furthest from the Control Box, using two 'U' type speed clips (from fastenings pack) as
shown in Fig. 11. Screw the remaining (6) retainers to each of the other Hanger Brackets to provide
location
for the Reflector Panels as shown in Fig.11.
NOTE
: the Reflector Panels, where located but not clamped, will be free to move and compensate for
expansion and contraction caused by temperature variation.
