4: Repair Overview

Cable and Assembly Placement
How the wires and cables are routed and dressed inside the chassis plays an important role in two areas:
in preventing long-term wear and potential pinching problems, and in reducing electromagnetic and
radio frequency interference emitted by the defibrillator/monitor.
• When you disassemble any part of the device, pay special attention to how cables and wires are
routed.
• When you reassemble the device, be sure to route and dress all cables and wires as they were
originally.
• Return all components to their original position within the case.
Device Reassembly
If your repair kit contains new accessories like shields, screws, etc., then install the new accessories and
discard the old ones.
Screw Usage
The HeartStart XL+ repair may involve removal and replacement of different screws, some of them may
look similar, but not interchangeable. Make sure you replace the same types of screws during reassembly.
If you do not reassemble the device correctly, it may no longer be properly sealed. This could result in
dust and moisture damage to the device. To ensure the adequate seal:
• Place all gaskets in their proper locations.
• Correctly assemble all parts that mate with gaskets (make sure the gaskets are not wrinkled, pinched,
or torn).
•Replace all screws.
• If installing several screws at a time, always install all the screws lightly, and then tighten in a
criss-cross pattern.
• Make sure that screws are not cross-threaded and firmly tightened.
• Unless instructed otherwise, torque:
– the M3 (T10) screws to 6 inch-lb (0.7 N m),
– the M4 (T15 and T20) screws to 10 inch-lb. (1.1 N m).
