5.4.11 Input Air Duct
There are two procedures for removing the input air duct. The procedure used depends on if
the TSZ07 has a plenum with or without a removable access panel. To remove the input air
duct, see Figure 5–14 and proceed to Section 5.4.11.1 or Section 5.4.11.2 as appropriate:
5.4.11.1 Removal Procedure Without Plenum Access Panel
Use this procedure if the plenum does not have a removable access panel.
1. Remove the front panel (refer to Section 5.4.7).
2. To remove the input air duct , gently move it backwards (towards rear of drive) to
disengage the two teeth from the metal shield (located behind the control panel) and
simultaneously disengage the duct from the plenum tooth by squeezing the left side of
the duct where it enters the plenum . Then slide the duct out of the plenum. (Rotating
the duct while you slide it out makes removing it easier.)
5.4.11.2 Removal Procedure With Plenum Access Panel
Use this procedure if the plenum has a removable access panel.
1. Remove the front panel (Refer to Section 5.4.7).
2. Remove the input air duct by moving it backwards to disengage the two teeth at
the front of the shield.
5.4.11.3 Replacing the Input Air Duct
Follow the appropriate removal procedure (Section 5.4.11.1 or Section 5.4.11.2) in reverse
order.
