WARNING: This product contains chemical known to the state of California to cause cancer or reproductive toxicity.

1. SAVE THESE INSTRUCTIONS – This manual contains important safety and operating instructions for battery charger models 1018.

2. When charging, batteries can emit explosive gases, therefore it is essential to prevent flames and sparks. The charger is designed for charging lead-acid batteries from 14 to 150Ah. Do not use for any other purpose. Do not expose to rain or snow.

3. Always provide good ventilation when charging.

4. Use of an attachment not recommended or sold by the battery charger manufacturer may result in a risk of fire, electric shock or injury to persons.

5. To reduce risk of damage to electric plug and cord, pull by the plug rather than cord when disconnecting charger.

6. An extension cord should not be used unless absolutely necessary. Use of improper extension cord could result in a risk of fire and electric shock. If an extension cord must be used, make sure that: a) Pins on plug of extension cord are the same number, size and shape as those of plug on charger; b) Extension cord is properly wired and in good electrical condition; and c) Wire size is large enough for ac ampere rating of charger as specified in “technical data”.

7. Do not operate charger with damaged cord or plug – return the charger to the place where purchased.

8. Never operate the charger if it has received a sharp blow, been dropped or otherwise damaged in any way; take it to a qualified serviceman.

9. Do not disassemble charger; take it to a qualified serviceman when service or re-pair is required. Incorrect reassembly may result in a risk of electrical shock or fire.

10. To reduce risk of electric shock, unplug charger from AC outlet before attempting any maintenance or cleaning. Turning off controls will not reduce the risk.

11. WARNING – RISK OF EXPLOSIVE GASES

    • a) WORKING IN VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS. BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY OPERATION. FOR THIS REASON, IT IS OF UTMOST IMPORTANCE THAT, YOU FOLLOW THE INSTRUCTIONS EACH TIME YOU USE THE CHARGER.
    • b) To reduce risk of battery explosion, follow these instructions and those published by the battery manufacturer and the manufacturer of any equipment you intend to use in vicinity of battery. Review cautionary marking on these products and on engine.

12. PERSONAL PRECAUTIONS

    • a) Consider have some one close enough by to come to your aid when you work near a lead-acid battery.

    • b) Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing or eyes.

    • c) Wear complete eye protection and clothing protection. Avoid touching eyes while working near battery.

    • d) If battery acid contacts skin or clothing, wash immediately with soap and water.
      If acid enters eye, immediately flood eye with running cold water for at least 10 minutes and get medical attention immediately.

    • e) NEVER smoke or allow a spark or flame in vicinity of battery or engine.

    • f) Be extra cautious to reduce risk of dropping a metal tool onto battery. It might spark or short-circuit battery or other electrical part that may cause explosion.

    • g) Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a lead-acid battery. A lead-acid battery can produce a short-circuit current high enough to weld a ring or the like to metal, causing a severe burn.

    • h) Use charger for charging a LEAD-ACID battery only. It is not intended to supply power to a low voltage electrical system other than in a starter-motor application. Do not use battery charger for charging dry-cell batteries that are commonly used with home appliances. These batteries may burst and cause injury to persons and damage to property.

    • i) Never charge a frozen battery.

13. PREPARING TO CHARGE

    • a) If necessary to remove battery from vehicle to charge, always remove grounded terminal from battery first. Make sure all accessories in the vehicle are off, so as not to cause an arc.
    • b) Be sure area around battery is well ventilated while battery is being charged.
    • c) Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
    • d) Add distilled water in each cell until battery acid reaches level specified by battery manufacturer. Do not overfill. For a battery without removable cell caps, such as valve-regulated lead acid batteries, carefully follow manufacturer’s recharging instruction.
    • e) Study all battery manufacturer’s specific precautions while charging and recommended rates of charge.
    • f) Determine voltage of battery by referring to car owner’s manual and make sure that the output voltage selector switch is set at correct voltage. If charger has adjustable charge rate, charge battery initially at lowest rate.

14. CHARGER LOCATION

    • a) Locate charger as far away from battery as DC cables permit.
    • b) Never place charger directly above battery being charged; gases from battery will corrode and damage charger.
    • c) Never allow battery acid to drip on charger when reading electrolyte specific gravity or filling battery.
    • d) Do not operate charger in a closed-in area or restrict ventilation in any way.
    • e) Do not set a battery on top of charger.

IMPORTANT SAFETY INFORMATION!

The MULTI US 7002 cannot be used to restore a fully worn out battery.
If the MULTI US 7002 does not switch to maintenance charge after three days (green light illuminated), there is a fault. Possible causes:

• The battery is probably worn out and should be replaced.
• Some large antimony batteries may behave different and can allow the MULTI US 7002 to charge the battery for too long, which can lead to overcharging. See caution!
• If heavy power consumers like fitted alarms and navigation computers are connected to the battery, the charging process takes longer and this can also overcharge the battery.
• A sulphated battery will only accept current with difficulty, and consequently the charg-ing process takes a particularly long time. A worn out battery cannot be fully charged. Therefore you should always check whether the charger has been switched to mainte-nance charge before you leave it turned on or unobserved for any length of time.
  Note: A battery that hasn’t changed to maintenance charge after three days is most likely worn out and needs to be replaced. All other batteries can be maintained for a very long time.

BATTERY TYPES AND SETTINGS

MULTI US 7002 can easily be set for different types of batteries or conditions. The follow-ing recommendations should, however, only be seen as guidelines. Please consult the battery manufacturer for further instructions.
Settings are made by pressing the ”MODE-button” and stepping forward one press at a time until the required mode is reached, the button is then released. After about 2 seconds the charger activates the selected mode. The selected mode is saved in a memory in the charger and remains there even if the charger is switched off.

NORMAL

| Mode 14.4V – Normal setting for wet batteries, maintenance free and for most Gel batteries. Some Gel batteries prefer a slightly lower charging volt- age. Please consult the battery manufacturer when in doubt.
---|---

| Mode 14.7V – This setting is recommended for a battery at temperatures

< 41°F. It is also recommended for many AGM batteries like Optima, and Odysseys. Consult your battery manufacturer when in doubt.

SUPPLY

| Mode 13.6V / Supply – The charger is operating at a constant voltage of 13.6V. This is the maintenance mode for applications where maximum ca- pacity from the battery is important, like floor sweepers and golf carts. Note that the Spark protection function is suppressed in this mode.

RECOND

| Mode 15.7V / 1.5A / 0.5–4h – This mode is used to recover deep discharged flooded batteries where you could expect a stratified acid (high acid weight in the bottom, low on top). This mode will also recover some spiral cell AGM batteries that has been deep cycled. Check with battery manufacturer when in doubt.

Note that the battery has to be fully charged first. Use this mode with care, because the high voltage will cause some water loss. 16V is normally no problem for electronics, but consult your supplier when in doubt. Life of light bulbs will be reduced at higher voltage. Try to avoid using 12V light from the battery during this phase. Maximum effect and minimum risk for electronics is achieved by charging a disconnected battery.

CHARGING

The battery charger must be connected to the battery according to the instructions above.

Start charging

1. Connect the power cord to the power outlet.

2. Set the proper charging mode for the battery by pushing the Mode button until the correct setting is lit. Choosing settings for your battery is described under ”BATTERY TYPES AND SETTINGS”.

3. The lamp for Deep Discharged battery (1) will indicate if the battery voltage is low.
   If lamp 1 blinks, this indicates that the battery is lightly sulphated. Read more under
   ”CHARGING PHASES”

4. Normal charging is indicated by the following lamps: Deep Discharged (1), Bulk Charge (2), Absorption Charge (3) or Maintenance Charging (4). When the maintenance lamp is lit, the battery is fully charged. The charge will restart if the voltage drops. The charger can be connected for months.
   SUPPLY or RECOND are indicated when the lamps for these settings are lit (5 or 6).

5. If the battery cables are connected incorrectly, the reverse polarity protection will make sure that neither the charger nor the battery are damaged. In this case, the red warning lamp (0) will be lit.

6. If nothing happens. If the setting lamp is lit but no other light comes on, the connection to the battery or to the chassis may be poor, or the battery may be faulty. Start by improving the contact between the battery and the charger.

7. Charging can be interrupted at any time by disconnecting the power cord from the wall socket. Always disconnect the power cord from the socket before removing the battery cables. When you interrupt charging of a battery mounted in a vehicle, always disconnect the battery cable from the chassis before removing the other battery cable.

CHARGING PHASES

Mode chosen: ”NORMAL” or ”SNOWFLAKE”
MULTI US 7002 is a multi stage fully automatic charger. Lamp B for chosen setting
”NORMAL” and lamp C for chosen setting ”SNOWFLAKE”.

Desulphation (Lamp 1, blinking)
Desulphation with pulsing for sulphated batteries. Indicated by blinking lamp

Start (Lamp 1)
Starting phase for charging. The starting phase continues until the battery’s terminal volt-age has risen over a preset level. At this point, charging goes into the bulk phase. If the terminal voltage has not reached the preset level within 8 hours, charging is suspended. The error mode is indicated. This indicates a battery which is faulty or has too large capacity. If a large battery is charged that has been severely discharged, it may be neces-sary to restart the charger after 8 hours. Start is indicated by lamp 1.

Bulk (Lamp 2)
Primary charging where approximately 80% of the charging happens. The charger delivers maximum voltage until the terminal voltage has risen to the preset level. After a number of hours, the charger goes on to the next phase, even if maximum voltage is not reached. Bulk is indicated by lamp 2.

Absorption (Lamp 3)
Final charging, voltage is kept at the preset level. During this phase, the charge current is gradually reduced. If the maximum length of time for Absorption is exceeded, the charger automatically continues with Analysis. Absorption is indicated by lamp 3.

Analysis (Lamp 3)
Charging is suspended for a short period and the battery voltage measured. If it falls too quickly, the battery is faulty. Charging is suspended and an error is indicated (lamp 0).

Maintenance charging – pulse (Lamp 4)
The state of charge varies between 95% and 100%. The battery receives a pulse when the voltage drops, keeping the battery in good shape when it is not being used. The charger can be connected for months at a time. If the battery is discharged and/or the battery’s terminal voltage drops, the charger starts a pulse charge until the voltage has reached the preset level, 14.4V or 14.7V. The charge pulse is then interrupted and the cycle is repeated as long as the charger is in pulse maintenance phase. If the battery voltage drops to 12.6V the charger automatically will begin to provide a float maintenance charge to the battery.

Maintenance charging – float (Lamp 4)
If the battery voltage drops to 12.6V the charger automatically will begin to provide a float maintenance charge to the battery. The battery is maintained with constant voltage of 13.6V. If the battery voltage drops even further the charger reverts to the beginning of the charging curve. Pulse and float maintenance are both indicated by lamp 4.

Chosen mode: ”SUPPLY”
MULTI US 7002 has a Supply mode setting which has a constant voltage of 13.6V and current up to 7A. This mode can also be used for maintenance charging of an already fully charged battery, called Float maintenance. This type of charging keeps the battery at 100% charge and minimize the battery water loss. The spark protection is not active in this mode. It is not appropriate to charge a completely discharged battery in Supply mode. In this mode, MULTI US 7002 can also be used as a power generation unit for operating equipment that requires 13.6V and a maximum of 7A. If the selected current exceeds 7A, the output voltage will drop as the load increases. The charger has electronic overload protection in this mode, which is activated if the charge is so great that the output voltage from the charger falls below around 9V and the current ís around 7A. In the event of an overload, the charger goes into error mode (lamp 0). Supply mode is indicated with lamp D and lamp 5.

Chosen mode: ”RECOND”
MULTI US 7002 has a Recond mode which is used to recondition a battery that has been severely discharged. The battery is first charged using the mode ”NORMAL”. When the analysis phase is complete, the charger begins reconditioning the battery by providing a constant current of 1.5A and a maximum voltage of 15.7V. After 0.5–4 hours, the battery is completely reconditioned and the charger goes into pulse maintenance. The battery is ready to be used, or store it with pulse maintenance active until you are ready to use the battery. Recond is indicated by lamp E and lamp 6. Note that the recond phase begins with normal charging and that the charger therefore will indicate the charging phases ac-cording to the descriptions above first. Lamp 6 is first lit when the reconditioning begins
