12.4 Living area battery
Observe the following to extend battery life:
Keep the battery surface clean and dry.
Check the acid level periodically and top up with desalinated or distilled
water as necessary. Never top up with acids.
If water loss is considerable, have the controller voltage checked by an
authorised specialist workshop.
Use an acid density measurement to check the battery's charging condi-
tion.
Acid density The battery must be recharged if the acid density falls below 1.21 kg/l. If
battery acid with a density of 1.23 kg/l is used, the battery must be
recharged when the acid density falls below 1.18 kg/l.
With acid density of 1.21 kg/l, the battery is protected against freezing at
temperatures up to -15 °C (at 1.28 kg/l up to -70 °C).
The battery has cycle stability and is thus particularly suited for vehicle power
supply. Cycle stability means that several discharge/charging processes are
possible.
12.5 Alde hot-water heater
Bürstner recommends either Molykote PG 65 or Vaseline as lubricants.
When replacing the battery, only use the same type of battery (same
capacity and voltage, cycle stability).
Never use conventional car batteries (starter batteries). A lead acid battery
must not be replaced by a dryfill battery.
Do not use so-called improvers.
Check the level of the heating fluid regularly on the compensator reservoir.
The compensator reservoir can be found in the wardrobe.
During or after the first operating hours of the hot-water heater, the filling
level may fall below the minimum mark. If this is the case, top up the
heating fluid.
Bürstner recommends to bleed the heating system after the initial heater
operation and to check the glycol content.
Have heating fluid changed by Bürstner dealer at intervals of approximately
two years as corrosion-protection wears off after some time.
Top up heating system with a water-glycol mixture (60 : 40) only. This mix-
ture offers frost protection up to -25 °C. When topping up hot-water heaters
that are connected to the engine's cooling circuit, please observe the
instructions in the manufacturers' instruction manuals.
Further information can be obtained from the separate instruction manual
"Alde Compact" heater.
