Pre-Spraying The Carpet; Plan For Cleaning - Nilfisk Advance ES4000 Mode D'emploi

A-8 / ENGLISH
FILLING THE SOLUTION TANK (REQUIRED FOR BOTH SWEEP MODE AND EXTRACT MODE)
1 Read the cleaning chemical label and calculate the proper amount of chemical to mix for a tank that holds 28 US gallons (110 liters).
2 Open the Solution Tank Cover (23).
3 Fill the tank 1/3 full of water, add the cleaning chemical then fi ll the tank to 7.62cm(3 inches) from the top of the tank opening.
NOTE: The machine can either be used conventionally with detergent mixed in the tank or the detergent system can be used. When using the detergent
dispensing system do not mix detergent in the tank, plain water should be used.
CAUTION!
Use low-sudsing, liquid detergents designed for carpet extraction. Water temperature should not exceed 130 degrees Fahrenheit
(54.4 degrees Celsius).
BEFORE USING THE ES4000
Thorough vacuuming of the carpet to be cleaned is not necessary before using the ES4000 automatic extractor, due to the on-board sweeping broom and debris
hopper. The area should be cleaned in Sweep Mode before being cleaned in Extract Mode.

PRE-SPRAYING THE CARPET

Pre-spray spots and heavy traffi c areas before extracting. Use a hand-held bottle sprayer or a pressurized "Hudson" type sprayer. Mix the pre-spray according to
the chemical manufacturer's directions.

PLAN FOR CLEANING

Before you begin extracting, look at the area to be cleaned and plan your work. Divide the space into sections. Overlap each pass 2 inches (5 cm).
DETERGENT SYSTEM PREPARATION AND USE (ONLY USED IN EXTRACT MODE)
COMMON INSTRUCTIONS:
Pressing and releasing the Detergent Switch (C) while in Restoration (H), Maintenance (G) or Prespray (I) mode will cause the detergent system to alternately turn
on and off. When the detergent system is ON, the detergent pump will be activated at a specifi c rate while the solution pump is running. The detergent pump will
turn OFF whenever the solution pump is not running or when the detergent system is turned OFF. Unless Prespray Mode (I) is selected, the detergent system
will be OFF by default each time the machine is powered up with the Key Switch (A). The detergent system will be selected by default when Prespray Mode (I)
is active. The Detergent ON / OFF Switch (C) is inactive when Sweep Power (D) is ON. The system should be purged of previous detergent when switching to a
different detergent. SERVICE NOTE: Move machine over fl oor drain before purging because a small amount of detergent will be dispensed in the process.
To Purge When Changing Chemicals:
1 Disconnect and remove the detergent cartridge.
2 Turn the Key Switch (A) ON. Press and hold the Detergent ON / OFF Switch (C) and the Solution ON / OFF Switch (B) for more than 2 seconds while the
controller is in any mode except standby to initiate a purge cycle. NOTE: Once activated the purge process takes 10 seconds. See illustration on next page
for Detergent System indicators. Normally one purge cycle is adequate to purge the system.
To Purge Weekly:
1 Disconnect and remove the detergent cartridge. Install and connect a Cartridge fi lled with clean water.
2 Turn the Key Switch (A) ON. Press and hold the Detergent ON / OFF Switch (C) and the Solution ON / OFF Switch (B) for more than 2 seconds while the
controller is in any mode except standby to initiate a purge cycle. NOTE: Once activated the purge process takes 10 seconds. See illustration on next page
for Detergent System indicators. Normally one purge cycle is adequate to purge the system.
When the Detergent Cartridge (18) is almost empty a Display Panel (E5) indicator will come on. The "Low Detergent" indicator will remain on until you reset the
system. Once this indicator comes on you should be able to simply pour an entire gallon bottle of detergent into the Cartridge to refi ll without worrying about
measuring. NOTE: Only reset the system when the cartridge is full. When switching cartridges, the "Low Detergent" indicator is only accurate if the replacement
cartridge is at the same level as the cartridge being replaced.
To Reset:
1 Turn the Key Switch (A) ON. Press and hold the Maintenance Mode Switch (G) and the
Restoration Mode Switch (H) for more than 2 seconds while the solution and detergent
are ON. The Detergent Reset Icon will display for 5 seconds. See illustration on next
page for Detergent System indicators.
Detergent Ratio:
1 The pre-programmed ratio can be adjusted. With the detergent system OFF, press and
hold the Detergent ON/OFF Switch (C) for 2 seconds. The detergent indicator will fl ash
and each press of the switch will cycle through the available ratios (1:64, 1:75, 1:100,
1:125, 1:150, 1:175, 1:200, 1:250). Once the desired ratio is displayed on the screen
(E6), stop and it will lock in after 5 seconds.
CARTRIDGE INSTRU CTIONS:
The Detergent Cartridge (18) is located behind the Detergent Cartridge Access Cover (6) in
the operator's compartment. Fill the detergent cartridge with a maximum of 1.25 gallons (4.73
Liters) of detergent. SERVICE NOTE: Remove the detergent cartridge from the detergent
box prior to fi lling to avoid spilling detergent on the machine.
It is recommended that a separate cartridge be used for each detergent you plan to use. The
detergent cartridges have a white decal on them so you can write the detergent name on each
cartridge to avoid mixing them up. When installing a new cartridge, remove the Cap (AA) and
place the cartridge in the detergent box. Install the Dry Break Cap (BB) and detergent hose
as shown.
