Introduction
The SKC Ltd single fast charger provides intelligent fast charging of AirChek 3000
pump battery packs in up to 3 hours (depending on initial charge state). Battery
pack full charge is detected based on the battery pack voltage and battery pack cell
temperature. After full charging the charger automatically switches to a trickle charge
rate to prevent overcharging.
The charger is supplied with four inter-changeable electrical supply input plugs suitable
for use in the United Kingdom, Europe, USA / Canada and Australia / New Zealand.
Warnings
This charger is designed for use specifically with SKC AirChek 3000 pumps and is not
intended for use with any other SKC or non-SKC products.
This charger must not be used to charge non-rechargeable batteries.
This charger is for indoor use only, with enclosure rating of IP40, and must therefore
be protected against exposure to moisture.
Operating temperature range - 0°C to +40°C, 95% RH non-condensing.
Use of a non-SKC charger to charge SKC pump battery packs may cause damage to
the battery pack and / or pump and will void the battery pack and / or pump warranty,
also the intrinsic safety rating of the pump may be invalidated.
Charger Operation
1. Select the correct electrical supply input plug for your region and fit it to the
charger.
2. Plug the charger into an electrical supply socket and switch on the electrical
supply. The charger LED indicator will illuminate yellow continuously to indicate
that it is in standby mode.
3. Plug the charger output connector into the charging socket on the battery pack.
The charger LED indicator will slowly flash yellow to indicate that the charger is in
its pre-charge phase.
4. During the pre-charge phase the charger checks the battery pack voltage and
temperature. If the temperature is above 50°C the charger goes into standby
waiting phase, with the LED indicator alternating yellow/green, until the battery
temperature drops below 45°C. If the temperature is below 0°C the charger

will trickle charge, with the LED indicator slowly flashing green, until the battery
temperature rises above 0°C.
5. If the battery pack voltage and temperature are outside of acceptable limits or
the charger detects a fault of the battery pack temperature sensor, at the end
of the pre-charge phase the charger LED indicator will rapidly flash yellow to
indicate an error. Disconnect and reconnect the battery pack to the charger. If the
error repeats this may indicate a faulty battery pack; contact SKC Ltd customer
support.
6. At the end of the 5 minute pre-charge phase the fast charge phase starts with the
LED indicator rapidly flashing green.
7. The charger detects that the battery pack is fully charged based on the battery
voltage and temperature. At the end of the fast charge phase the charger enters
the maintain phase, trickle charging at approximately 5% of the fast charge rate
for approximately 1 hour, with the LED indicator slowly flashing green. During this
phase the individual battery cells are balanced to the same charge state.
8. At the end of the maintain phase, the charger will switch to the ready phase,
trickle charging at approximately 2% of the fast charge rate, with the LED indicator
showing green continuously. The battery pack is fully charged and ready for use.
9. It is recommended to disconnect the charger from the battery pack after a period
of 24hours to maintain optimum battery life and performance..
10. It is recommended to disconnect the charger from the electrical supply when not
in use to save the energy the charger consumes when on standby.
