Maintenance
Always disconnect the
electrical supply before
attempting to install,
service, relocate or perform any

Improper repair could result fatal in
electrical shock.
1. Once a month, check battery
condition.
2. Unplug the wall charger.
3. For batteries with top caps that can
be removed, the electrolyte level
should be checked and filled to
Corrective Action

open for the pump to prime. With the pump unplugged, remove the
4 screws on the bottom of the pump to release the housing around
the impeller. Clean out the hole and replace cover
5. If discharge is too high, a separate line may be required with a lower
discharge height
6. Check battery and replace if low or defective
1. Tether length should be at least 2". Adjust if necessary

charge for each cell should be
checked with a hydrometer. A
specific gravity of 1.265 indicates the
battery is at full charge. If the specific
gravity of any of the cells varies more
than .050, the battery should be
replaced.
