11. Put the chassis together and put into the case. See "Chassis" on page 5-11.

Quick Connect Fittings (QC) and Filter

Use the following instructions and Figure 5-17 to replace both of the QC fittings ().
1. Remove the chassis and separate the chassis. See "Chassis" on page 5-11.
2. Put the control panel () on a flat work surface upside down.
Depending on the previous level of disassembly the control panel assembly
screws may not be fully removed as the spacers help captivate the screws.
The screws must be fully removed to remove the support bracket (). Hold
the spacer tube to prevent it from spinning while removing the screws.
3. Remove the three screws () that secures the HM2 collar () to the quick connect
(). These are the three which are elevated above the other three.
4. Remove the three screws () that secures the QC adapter () to the quick connect
(). Be careful not to lose the small filter element from the underside of the QC
adaptor as it is free to fall out when the adaptor is removed from the quick connect
body.
5. Remove the quick connect () from the control panel ().
6. Remove the filter () from the QC adapter ().
7. Put the filter () in the new quick connect adapter ().
8. Position the quick connect fitting on the control panel and the o-ring () on the
opposite side of the panel.
9. Position the QC adapter () and secure it to the quick connect () with three
screws (). Before tightening the screws, pull down on the QC sleeve as if to
release the QC two or three times to help center the QC. Tighten the screws in a star
shaped pattern. After tightened, torque the screws to 2.3 Nm (20.4 in-lb).
10. Position the HM2 collar () on top of the QC adapter () and secure it with three
screws () and lock washers (), and flat washer (). Ensure that there is a small
gap 0.25 mm to 0.5 mm (0.010 in to 0.020 in), between the QC adapter and the
HM2 collar. If necessary adjust the position on the HM2 collar to ensure this small
gap.
11. Put the chassis together and put into the case. See "Chassis" on page 5-11.
