Recording the expiration date of the battery and hydrostatic release unit
After installing the float-free DRU, record the expiration date of the battery (inside the
float-free DRU (capsule)) and hydrostatic release unit.
• Battery in the float-free DRU
Calculate the expiration date of the battery from the year and month of packing. The
year and month of packing for the battery is written on the sticker at the side of the
capsule.
Calculate the expiration date as follows;
Year and month of the installation ≤ Year and date of packing + 1.5 years:
The expiration date is the year and month of the installation + 5 years.
Year and month of the installation > Year and date of packing + 1.5 years:
The expiration date is the year and month of packing + 6.5 years.
Cut out the expiration date from the sticker supplied with the float-free DRU, then
attach the sticker to the side of the capsule.
Example: When the expiration date is April 2019.
Cut out "2019".
Cut out "4".
