ACR&Artex Float-Free 406 Memory Capsule - Manual (Page 19)

Y1-03-0199 Rev. E 16
SECTION 6 - CARE AND MAINTENANCE
At least every ninety days, the mounting bracket and float free memory capsule should be inspected for deterioration
and/or buildup that may affect the function of the memory capsule or automatic release.
Also carefully inspect the memory capsule case for any visible cracks. Cracks may admit moisture, which could falsely
activate the memory capsule or otherwise cause a malfunction. Any cracking observed should be immediately returned
for repairs (See returning product information on page 1).
Clean the memory capsule and the mounting bracket to remove residue buildups. It is recommended that the mounting
bracket be wiped with a damp cloth.
The hydrostatic release unit (HRU) must be replaced by the date indicated on the float free mounting bracket. The
hydrostatic release can be replaced by removing the memory capsule from the bracket, then sliding the hydrostatic
release assembly out of the keyed opening on the spring and mounting bracket. Insert the new hydrostatic release
assembly, in place by engaging it to the opening of the ejection spring and case. When servicing the HRU, it is
required that you replace the entire hydrostatic assembly, including hydrostatic release, release rod and all hardware
(P/N 9490 Universal kit). Failure to replace the entire assembly can cause the bracket to malfunction. Always use
original ACR replacement parts. Use of unauthorized replacement parts will void your warranty and may cause the
bracket to malfunction. Place memory capsule into the mounting bracket, and replace cover, securing in place with
hitch pin going through the hydrostatic release rod.
Check antenna for tightness.
The battery (P/N 1078) must be replaced by the date indicated on the memory capsule. At each inspection, check the
time remaining until replacement is required. Battery should be replaced if the memory capsule has been activated for
any use other than the self test.
NOTE: There are no user serviceable items inside the memory capsule. DO NOT OPEN THE MEMORY
CAPSULE EXCEPT TO DISABLE IN CASE OF FAULTY ACTIVATION.
Self contained long life batteries with a five-year recommended replacement cycle provide power. See factory
authorized service center for replacement.
Battery replacement includes servicing the memory capsule by replacing the lithium batteries, o-rings, testing the water
seal and the electrical properties.
Always refer all long life battery replacement and other memory capsule service to a factory authorized service center.
For battery replacement information, please refer to Section 10.
The memory capsule contains lithium batteries which meet the requirements of the DOT Hazardous Materials
Regulations. They also meet the United Nations Classification of Lithium Batteries for Shipment as "Non
– Dangerous
Goods".
Data transfer cable cutting mechanism
Like the HRU, the data transfer cable and cutting mechanism (ACR P/N 2518) should be replaced every two years.
