5.12 Battery care
If the battery is still dry, it must be activated as described in section
5.12.2.
The battery must be in operation within 2 months from being
activated; if not, it needs to be recharged first.
5.12.1 Electrolyte
Electrolyte in batteries is a sulphuric acid solution in distilled
water.
The solution must be made up before being introduced into the
battery.
5.12.2 Activating a dry-charged battery
– Take out the battery.
– Battery and electrolyte must be at equal temperature above 10°C.
– Remove cover and/or plug from each cell.
– Fill each cell with electrolyte until the level reaches 10 to 15 mm
above the plates, or reaches the level marked on the battery.
– Rock the battery a few times so that possible air bubbles can escape;
wait 10 minutes and check the level in each cell once more; if
required, add electrolyte.
– Refit plugs and/or cover.
– Place the battery in the compressor.
5.12.3 Recharging a battery
Before and after charging a battery, always check the electrolyte
level in each cell; if required, top up with distilled water only.
When charging batteries, each cell must be open, i.e. plugs and/or
cover removed.
Apply with preference the slow charging method and adjust the
charge current according to the following rule of thumb: battery
capacity in Ah divided by 20 gives safe charging current in Amp.
To keep a battery charged, use the unit’s battery charger.
Do not use this battery charger to charge an empty battery.
5.12.4 Maintaining the battery voltage
To maintain the battery voltage, use the unit’s automatic battery
charger.
– Battery charger EEC/AUS: 240 VAC / 24 VDC - 100 VA
– Battery charger USA: 120 VAC / 24 VDC - 100 VA
When power is supplied to the charger, the battery voltage will be
kept within preset limits.
Three LEDs on top of the battery charger show the charging
condition:
– Green: AC supply voltage present
– Yellow: Battery voltage high
– Red: DC voltage present / unit charging
5.12.5 Battery maintenance
– Keep the battery clean and dry.
– Keep the electrolyte level at 10 to 15 mm above the plates or at the
indicated level; top up with distilled water only.
– Keep the terminals and clamps tight, clean, and lightely covered
with petroleum jelly.
5.13 Fuses
The Compressor Control Module (CCM) is equipped with the
following five fuses:
Before handling batteries, read the relevant safety
precautions and act accordingly.
Read the safety instructions carefully.
Use a commercial automatic battery charger
according to its manufacturer’s instructions.
Do not use the unit’s automatic battery charger to
charge an empty battery. In this case use a commercial
automatic battery charger (see section 5.12.3).
