User's Manual and a guide

for Starter/Deep Cycle batteries.
INTRODUCTION
The ZAFIR 90 is a switch mode charger with pulse maintenance and is one
of a series of professional chargers from CTEK SWEDEN AB. It represents
state-of-the-art technology within battery charging. A ZAFIR 90 will prolong
the service life of your battery. Please read this manual carefully and follow
the instructions.
CHARGING
Charging batteries in a vehicle:
1. The power cord should be removed from the power outlet before connect-
ing or disconnecting the battery leads.
2. Identify which of the poles is the earth (connected to the chassis). The
earth is normally connected to the negative terminal.
3. Charging of negative earthed battery: Connect the red wire to the positive
pole of the battery and the black wire to the vehicle chassis. Make sure the
black wire is not connected close to a fuel hose or the battery.
4. Charging of positive earthed battery: Connect the black wire to the negative
pole of the battery and the red wire to the vehicle chassis. Make sure the red
wire is not connected close to a fuel hose or the battery.
Charging of a battery not connected to a vehicle:
1. The power cord should be removed from the power outlet before connect-
ing or disconnecting the battery leads.
2. Connect the red wire to the positive pole of the battery and the black wire
to the negative pole.
Begin Charging
1. Set the correct voltage for the battery by pushing the Mode Selector Button
until the light for the correct voltage is lit (see Battery Types and Settings).
2. When you are sure the battery leads are correctly placed, connect the
power cord to the power outlet to begin charging. If the battery leads are
wrongly connected, the pole-changing switch will ensure the battery and
charger are not damaged. The fault indicator will light. In which case start
from the beginning again.
3. The charging lamp will now indicate charging or the maintenance
lamp will indicate that the battery is fully charged. If the voltage drops the
charger sends a pulse to the battery. The length of the pulse depends on how
much the voltage has dropped. The charger can be connected for months.
4. If nothing happens: If the voltage indicator is lit but no other lamp is lit there
could be a bad connection to the battery or chassis or the battery could be
faulty. Check the wall power outlet. If you experience problems: start with the
sensitive connection between the battery clamps and the charger.
5. Charging can be stopped at any time by disconnecting the supply cord
or by setting the charger on Standby. Always remove the power cord from
the power outlet before disconnecting the battery leads from a battery in a
vehicle. When you stop charging a battery in a vehicle, remove the cable from
the chassis before removing the other cable.
6. If the charger lamp and the maintenance-charger lamp are fl ashing alter-
nately, the reason for this is due to:
• An interruption during charging, due to a loose connection or because the
battery has ceased to work.
• The battery has become sulphated. If the lamps fl ash for more than 30
minutes, this indicates that the battery is dead and needs to be replaced.
• If there is an interval of more than 10 seconds between the fl ashes, this
indicates that the battery has a high self-discharge rate and may need to be
replaced.
SAFETY
• The charger is designed for charging 1.0-90 Ah lead-acid batteries. Do not
use it for any other purpose.
• Always use safety goggles and turn your face away from the battery when
turning it on and off!
• When being charged, batteries could emit explosive gases. Prevent fl ames
and sparks close to the battery.
• Always provide for proper ventilation during charging.
• Avoid covering the charger.
• Battery acid is corrosive. Rinse immediately with water if acid comes into
contact with skin or eyes. Seek medical advice.
• Never charge a frozen battery
• Never place the charger on top of the battery when charging.
IMPORTANT SAFETY INFORMATION!
Not even the world's smartest battery charger can save a used battery! If the
charger has not switched to maintenance charging (green lamp on) after three
(3) days, this indicates that something is wrong. Possible reasons:
• It is most likely that the battery has been used up and needs replacing.
• A larger, older type of battery, known as an antimony battery, behaves in a
completely different way to modern batteries. Due to the construction of the
battery, a ZAFIR 90 might charge the battery for too long, which may result in
the battery becoming overcharged.
• If equipment such as alarms and on-board computers, which consume a lot
of power, are connected to the battery, charging will take a long time and in
this case too the battery may become overcharged.
• The reduced charge acceptance for a sulphated battery increases the
charging time. Some batteries will never be fully charged.
You should therefore always check that the charger has switched to main-
tenance charging before leaving the charger unsupervised and connected
for longer periods of time. If the charger has not switched to maintenance
charging within three (3) days, the charger must be manually disconnected.
If the charger has switched to maintenance charging, there is nothing wrong
and the battery is probably sound and will function properly for a long time
together with ZAFIR 90.
