For freshwater diving, at the end of the last dive of the day, slide the rubber band that covers the
body/tail connection forward and remove the recharge plug cover from the nose of the DPV.
Remove the propeller assembly, drain any water from the propeller coupling cavity and carefully
reinsert the propeller.
For saltwater diving, slide the rubber band that covers the body/tail connection forward and
remove the propeller from the tail section. Rinse the propeller by dunking it in fresh water a few
times and then rinse the DPV by submerging it in fresh water for twenty minutes. Remove the
recharge plug cover from the nose when the DPV is removed from the rinse bath. If a rinse bath is
not available, remove one orange plastic locking strip between the tail and the body, rinse the
strip and direct the flow of fresh water from a hose, into the slot for a minute or two. Reinstall the
first strip and repeat the process with the second strip removed and then rinse the rest of the DPV.
Drain any water from the propeller coupling cavity and carefully reinsert the propeller.
If you think you may have discharged the batteries below 40% capacity, recharge the batteries
before storing the DPV as suggested in the Recharging section of the manual.
If you will be storing the DPV for more than one month before the next dive, it is recommended to
open the DPV and disconnect the batteries. This will prevent the need for a maintenance charge
being performed due to a very small voltage drain needed by the charger, to sense the batteries.
Always remember to remove the recharge plug
cover when not in use or the batteries may be
permanently damaged by over discharge. Over
discharge is not covered by the warranty!
Care and Maintenance
The Genesis DPVs are designed so that minimum maintenance is required. A thorough rinse after
diving in salt water is the most important preventative maintenance item. Always slide the rubber
band forward of the body/tail connection to allow water to drain and dry between days of diving.
Whenever the body is removed, carefully check the o-rings, o-ring grooves and body sealing
surfaces for dirt or debris. Check the o-rings for nicks or deformation and generously grease with
Dow Corning Molykote 111 valve lubricant or equivalent. The body o-rings are Buna-N, size -168,
70 durometer. Two spare body o-rings are included and it is best to keep them pre-greased in a
plastic bag with the spare orange plastic lock strips, inside the DPV, so they are always available,
should you need them.
