BATTERY TYPE
To power the machine you can use either wet batteries or AGM batteries. Other types must not be used.
The maximum dimensions and the weight are:
Width: 7 1/8 in (181 mm)
Length: 10 3/8 in (264 mm)
Height: 11 5/8 in (295 mm)
Weight: 72 lb (33 kg)
BATTERY INSTALLATION
The machine will be supplied with a battery charger and either four 6V wet or AGM
batteries. The batteries must be housed in the battery compartment beneath the
recovery tank.
To insert batteries:
1. Lift the recovery water tank, opening it as far as it will go using the side handle.
2. The batteries must be lowered into the compartment using lifting and
transportation means suitable for the weight and dimensions.
3. They must be connected together in series, to obtain overall voltage of 24V on
the lugs.
NOTE: Fully charge the batteries before using the machine.
NOTE: Your charger must be set according to the type of battery you install. Read charging section of manual for further instructions on how
to set your charger correctly for your battery type.

NOTE: The on-board charger has been programmed to work with the batteries that Pacic Floorcare provides. Using other battery
types not specied for the S-Series mid-size scrubber by Pacic Floorcare may impair performance of the unit and will affect
the life of the batteries.

MACHINE PREPARATION
BATTERY POWER LEVEL INDICATORS
The battery power level gage is located on the upper control panel. The gage has a series of LEDs to indicate the amount of power left in the
batteries. When the batteries have a full charge, all LEDs are lit. As the batteries are discharged, the LEDs will begin to go out from right to
left. To maximize the life of the batteries, do not allow the LEDs to go beyond the discharge level as described below.
To maximize the life of the batteries, only recharge the batteries when the machine is operated for a total of 30 minutes or more and always
recharge the batteries immediately after usage when LEDs are indicating charging is required as described below.
BATTERY POWER LEVEL INDICATOR
The battery power level gage is located on the upper control panel. The gage has red, yellow and green
LEDs to indicate the amount of power left in the batteries.
On lead acid battery-equipped units, when the discharge level reaches the rst red LED, it is a good time
to nish your scrubbing application and recharge the unit. If you do choose to continue scrubbing, when
the last red LED begins to ash, the unit will shut down the brush motor but leave the vacuum and
traction drive operational to perform nal water recovery and transport back to storage. This function
not only serves as an indicator that your battery level has reached a point where recharging is required,
but also protects the batteries from being fully discharged.
AGM battery-equipped units should not be used after the last yellow LED goes out leaving only red
LEDs. Using the unit beyond this point can reduce the life of the batteries.
NOTE: The battery power level gage also displays fault codes. The LEDs will ash specic fault codes if
a fault is detected. See Troubleshooting section for LED fault codes.

CHARGING THE BATTERIES WITH AN ON-BOARD CHARGER
Before using your S-Series mid-size scrubber for the rst time, fully charge your batteries.
MACHINE PREPARATION
USING YOUR ON-BOARD CHARGER
The on-board charger has charging indication LEDs - the red LED means it has just started the charging cycle, the yellow LED indicates that it
has reached the second phase of charging and green LED means the unit is fully charged.

The on-board charger is equipped with a 9 foot long cord that can be plugged directly into a 120V outlet. Do not use an extension cord.
This will void the warranty on the charger.
The cord wrap on the unit has a quick-release hook. The lower hook allows the user to slip the cord off and then the cord can be lifted off
the upper hook, all without having to unravel the entire cord.
After charging is complete, wrap the cord of your on-board charger securely to ensure the cord is not damaged.

MACHINE PREPARATION
SETTING THE DIP SWITCHES ON YOUR ON-BOARD CHARGER FOR YOUR BATTERY TYPE
Both the on-board and off-board chargers are able to charge wet, lead acid or maintenance-free AGM batteries. As
your unit leaves Pacic Floorcare’s factory, the charger is set up to match the type of battery chosen in the original
machine order. Should you choose to change from the original battery type, the charger can be changed by re-setting
the dip switches.
NOTE: The on-board charger has been programmed to work with the batteries that Pacic Floorcare provides. Using
other battery types not specied for the S-Series mid-size scrubber by Pacic Floorcare may impair performance of the
unit and will affect the life of the batteries.
To access the dip switches, use a small screw driver to lift the corner of the label on the on-board charger and peel back
partially to reveal them. Set the dip switches as shown below for the specic battery type being used in your machine.

Off-board charger
The off-board charger has charging indication LEDs. The primary LED is
green and if blinking slowly, then the batteries are still below 80% of full
charge. If blinking fast, then the batteries are above 80% of full charge while
if solid green, the batteries are fully charged. There is a red “fault” LED
as well. In the rare occurence that this LED comes on, check the charger
operator manual for troubleshooting guidance.

The off-board charger has both a standard 120V power cord and a cord with an “Anderson connector”.

MACHINE PREPARATION
SETTING THE DIP SWITCHES ON YOUR OFF-BOARD CHARGER FOR YOUR BATTERY TYPE
The off-board charger is able to charge wet, lead acid or maintenance-free AGM batteries. As your unit leaves Pacic Floorcare’s factory, the
charger is set up to match the type of battery chosen in the original machine order. Should you choose to change from the original battery
type to the other, the charger can be changed by re-setting the dip switch.
To re-set the dip switch, slide the switch up for wet, lead acid batteries (battery part number 871301) or down for sealed,
maintenance free AGM batteries (battery part number 871302).

It is easy to gage the solution level by watching the fog-free solution sight gage at the rear of the
machine. Additionally, marks on the tank provide solution level indicators as a guide.

NOTE: Always use low-foam detergent. Introduce a small amount of defoaming liquid in the recovery tank
before starting work to prevent foam from being generated. Never use pure acids.

Water and cleaning agent can be added to the S-Series mid-size scrubber’s rear hose ll port located to
the left of the control panel.
Liquid detergent should be added to the tank in the concentration and manner specied by the
manufacturer for an twenty two (22) gallon solution tank. The formation of excess foam could damage the
vacuum motor, so be sure to use only the correct amount of detergent. Water temperature should not
exceed 120°F (50°C).
