Attention
Never store the machine with discharged
batteries. Otherwise, the batteries will be
damaged beyond repair. Be sure to fully
charge batteries whenever storing the
machine.
16. Charging
The battery pack may be recharged while in the robotic oor
scrubber system.
Only recommended 24 volt gel cell
battery charging systems should be used.
Overheating, re, and explosion could result
from improper battery charging.
The charge current should be limited to 20
Amps or less. Do not charge the system
with a current higher than 20 Amps or
damage could result.
It is typical of a gel cell charger set at 20
Amps to initially overshoot to as much as
30 Amps and then settle back to around
20 Amps. This is acceptable as long as
it settles back to 20 Amp within a few
seconds.
16.1. Locating the Charger
The location and mounting of the battery charger should be
considered before charging the system or battery pack.
Figure: 34
The battery charger connects to the high
voltage mains. The charger must be located
on a wall, away from wet areas, to avoid a
shock hazard.
Caution
To avoid water shorting the charger it should
be mounted above tank no less than 12"
(31 cm) above, either on a shelf or to the
wall per charger manufacturers instructions.
Periodically inspect the mains and charging
cables to ensure the integrity of the
insulation. Do not use the charger if the
insulation is nicked or cracked.
16.2. Charging the System
Before charging the battery, ensure the parking brake is set.
Figure: 35
Turn off the system by following instructions from "Figure: 31"
on page 16.
