5. Measure the wall thickness and add 25mm.
This is dimension "X" (Fig. 25.
6. Mark off dimension "X" on the outer tube,
measuring from the rear of the chassis. Cut off
the excess material (Fig. 26).
7. Remove any burrs from the tube.
8. Measure the waste from the outer tube and
cut the same amount off the base of the divider
board (Fig. 26).
9. Replace the rubber seal 50mm in from the
end of the tube and secure using the adhesive
provided.
10. Refit the plastic ring using the adhesive
provided.
11. Subtract 1.5mm from dimension "X". This
will be dimension "Y".
12. Mark off dimension "Y" from the motor
housing end of the inner tube, and scribe a line
around the inner tube. Peel the two motor wires
away from the wiring tunnel beyond the scribed
line to prevent damage. Carefully cut the
excess off the tube (Fig. 27).
13. Remove any burrs from the tube.
14. Reassemble the tubes in reverse order
ensuring that the two motor wires are located
back in the wiring tunnel, and that the tunnel is
aligned with the wiring slot in the chassis
(Fig. 28).
15. Replace the heat exchanger according to
the 'Inside/Outside' labels. The recess in the
heat exchanger outer must be aligned with the
wiring tunnel on the inner tube to ensure the
divider slot is vertical (Fig. 28 and 29).
16. Cut the two motor wires to size and
reconnect to their respective terminals (Refer to
the relevant unit instructions - see pages 7-8).
Continue installing the unit from paragraph 7
onwards in the relevant unit instructions - see
pages 7-8.
