Install the new liners
CAUTION
Ensure that you fit the inner liner (Figure 4, item 2) in the correct orientation. If you do
not, the pump exhaust gases will not flow correctly through the liners and the trap will not
operate effectively.
Refer to Figure 2 in the following procedure.
1.
Fit the inlet elbow (11), the new inlet insulator (13) and the two new 'O' rings (9), then fit and
tighten the eight M6 nuts and washers (12): do not over-tighten the nuts, as you may damage
the inlet insulator.
2.
Fit the new inlet liner (10) into the trap inlet (11); note that you can slightly compress the liner
to ease its insertion.
3.
Fit the new inlet gasket (14) in the trap body; ensure that the off-centre hole in the gasket
aligns with the trap inlet (11).
4.
Fit the new inlet end-shield (16) into the trap with the lifting-tabs (Figure 3, item 10)
upwards; ensure that the off-centre hole in the end-shield aligns with the trap inlet (11).
5.
Fit the new cold-finger liner (17) over the cold-finger (8); note that you can slightly expand
the liner to ease its insertion.
6.
Fit the new cold-finger end-cap (6) inside the top of the cold-finger liner (17); note that the
end-cap is tapered and you must fit the end-cap with the recess in the cap upwards.
7.
Align the new outer liner assembly so that the long fin on the inlet segment is adjacent to the
trap inlet (see Figure 4), then slide the outer liner assembly into the body of the trap; as you
slide the assembly into the trap, allow the retaining rings (Figure 3, item 19) to slide up the
outside of the liner segments until they come off. Dispose of the two retaining rings.
8.
Fit the new inner liner (7) into the trap so that the gap in the bottom of the liner aligns with the
long fin on the outer liner (see Figure 4); note that you can slightly compress the liner to ease
its insertion.
9.
Fit the new outlet end-shield (5) into the trap.
11. Fit the new outlet gasket (3) into the trap.
11. Remove the dust-cover from the trap outlet and fit the new outlet liner (2) into the trap outlet
(1). Two outlet liners are supplied; use the correct size outlet liner for your trap. Note that
you can slightly compress the liner to ease its insertion.
12. Place the new top-flange 'O' ring (20) in position. Note that two 'O' rings are supplied; use
the correct size 'O' ring for your trap.
13. Refit the top-flange (21) to the trap-body (19); ensure that you do not displace the top-flange
'O' ring. Secure the top-flange to the trap with the eight thumbwheels (4).
