SELECTION OF LOW VOLTAGE CUTOUT THRESHOLD:
The HR 2800 / BR 700 is equipped a low voltage cutout feature to prevent over-discharging the batteries. This feature will automatically
shut down the scrub system when the battery voltage falls to the selected threshold. The cutout level is adjustable. The standard setting
is 21 volts (1.75 volts per cell) and the so called maintenance free setting is 22 volts (1.83 volts per cell). The standard setting should
be used unless the battery manufacturer specifies the higher cutout voltage.
It is important to mote that some maintenance free
batteries (including some gelled electrolyte cells) are capable of being safely discharged down to 1.75 volts per cell.
To select between
the two types:
1
Turn the master on/off key switch to the off position.
2
Press and hold the scrub off switch.
3
While holding the scrub off switch turn the master on/off key switch to the on position.
4
Continue to hold the scrub off switch until the scrub off indicator turns green and the hourmeter/status display shows “Std” or “FrEE”.
5
Release the scrub off switch.
6
Pressing and releasing the scrub off switch will now select between the two options. For standard wet cell batteries select “Std”
and for maintenance free batteries select “FrEE”.
7
To save the new setting, turn the master on/off key switch to the off position.
8
The new setting will be saved and will remain in effect until it is changed again.
ADJUSTMENT OF NORMAL SCRUB MODE PAD PRESSURE:
The default pad pressure setting when the normal scrub option is selected is adequate for most scrubbing operations. If it is desired to
increase or decrease the amount of pad pressure for the normal scrub mode perform the following steps. NOTE: At the maximum pad
pressure setting for the normal scrub mode, the pad pressure will still be less than the pad pressure when in the heavy scrub mode.
1
Turn the master on/off key switch to the off position.
2
Press and hold the normal scrub switch.
3
While holding the normal scrub switch turn the master on/off key switch to the on position.
4
Continue to hold the normal scrub switch until the scrub off indicator and/or the normal scrub indicator turns green and the hourmeter/
status display shows “PA 0” (the factory default setting).
5
Release the scrub off switch.
6
Pressing and releasing the scrub off switch will now decrease the pad pressure setting. If a setting below the factory default setting
is chosen the display will show “PA -X” where X is a number from -1 to -4. The minimum amount of pad pressure is selected when
the display shows “PA -4”.
7
Pressing and releasing the normal scrub switch will now increase the pad pressure setting. If a setting above the factory default
setting is chosen the display will show “PA X” where X is a number from 1 to 2. The maximum amount of pad pressure is selected
when the display shows “PA 2”.
8
To save the new setting, turn the master on/off key switch to the off position.
9
The new setting will be saved and will remain in effect until it is changed again.
