305 AH @20 HR RATE
BATTERY SPECIFICATIONS
- Use a combination of multiple 2-volt cell units to construct a 24 or 36 Volt DC battery pack system.
- Nilfisk-Advance recommended battery pack capacity is a 238 AH @ 20 Hour Rate deep cycle battery system. Note: The battery pack must fit
the battery compartment size listed in
Specifications
.
BATTERY CHARGER SPECIFICATIONS
- Use a 24 or 36 Volt DC output charger matching the DC battery pack voltage and the input AC line voltage supply being used.
- Always when selecting a battery charger follow the recommendation of the battery supplier to match the proper charger DC output amperage
to the amp/hour rating batteries being installed. This will prevent the battery pack from being over or under charged.
- The recommended 238 AH battery should be matched to a 24V, 25 Amp output charger on machines using (4) batteries and a 36V, 25 Amp charger
on machines using (6) batteries.
INSTALL THE BATTERIES
WARNING!
FIGURE 1
Use extreme caution when working with batteries. Sulfuric acid in batteries can cause
severe injury if allowed to contact the skin or eyes. Explosive hydrogen gas is vented
from inside the batteries through openings in the battery caps. This gas can be ignited
by any electrical arc, spark or flame.
When Servicing Batteries...
•
Remove all jewelry.
•
Do not smoke.
•
Wear chemical goggles, rubber gloves and a protective apron.
•
Work in a well-ventilated area.
•
Do not allow tools to touch more than one battery terminal at a time.
CAUTION!
Electrical components in this machine can be severely damaged if the batteries are not
installed and connected properly. Batteries should be installed by Nilfisk-Advance or by
a qualified electrician.
1
Remove the batteries from their shipping crate and carefully inspect them for cracks or
other damage. If damage is evident, contact the carrier that delivered them or the battery
manufacturer to file a damage claim.
2
Turn the Master Key Switch
(B)
OFF and remove the key.
3
Tip the recovery tank to the side, locked position. Remove the battery cables from inside
the battery compartment.
4
Your machine comes from the factory with enough battery cables to install four or six (6
volt), 305 Amp hour batteries. Carefully lift the batteries into the battery compartment and
arrange them exactly as shown. Secure the batteries as close to the back of the machine
as possible.
5
The terminals on the battery cables are marked “+” for positive and “-“ for negative. Install
the battery cables as shown, with the terminals marked “+” on the positive battery terminals
and the terminals marked “-“ on the negative terminals. Position the cables so the battery
caps can be easily removed for battery service.
6
Carefully tighten the nut in each battery terminal until the terminal will not turn on the battery
post. Then tighten the nut one additional turn. Do not over-tighten the terminals, or they will be very difficult to remove for future service.
7
Coat the terminals and posts with spray-on battery terminal coating (available at most auto parts stores).
8
Put one of the black rubber boots over each of the terminals.
DESCRIPTION OF THE BATTERY LOW VOLTAGE CUTOUT FEATURE
All models discussed in this manual are equipped with a low voltage cutout feature to prevent over-discharging of the batteries. When a machine’s
battery pack voltage falls below specifically defined thresholds (voltage settings) the scrub system is automatically shut down. The cutout level
is adjustable. The standard lead acid battery (wet cell) setting is 1.72V per cell and alternate maintenance free battery (gel cell) setting is 1.81V
per cell. The standard setting is factory selected and should be used unless the battery manufacturer specifies the higher cutout voltage.
Special Service Note:
On all the 24V & 36V machines a minimum recharge voltage of 2.09 volts per cell must be reached to allow the scrub brush
and solution system to (reset) function again. A 24V-battery pack must increase to a 25.1-volt minimum and a 36V battery pack to 37.6 volts.
