Charging the battery

The device must be switched off for char-
ging. The battery is charged within 12 to 14
hours using the plug-in power supply pro-
vided (maximum charging current 150 mA).
The red LED on the indicates the charging
procedure and is illuminated permanently
when charging. Charging should take place
in a temperature range from 0 to 45°C. Over
500 charge and discharge cycles can be ex-
pected under normal conditions. Long peri-
ods of storage or charging the battery for too
long reduce the cell capacity. This capacity
loss can be compensated for by means of a
full charge or 1 to 3 charge and discharge
cycles.
7 Device-related requirements in
accordance with DVWG G 465-4
and technical data
7.1 General device-related requirement in ac-
cordance with DVGW G 465-4
This DVGW regulation affects mobile devices
for determining leaks on systems for public
gas supply as well as on client's own systems
(in-house installations). Here, the term "gas
detector" refers to devices for detecting gas
concentrations with a detection sensitivity of
19
< 100 ppm combustible gas, i.e. devices that
are preferably used for gas detection when
looking for leaks. The required device proper-
ties should be specified in the manufacturer's
operating manual where relevant.
8 Leak detection on the
A/C system
During leak detection on the A/C system, the
parts provided (service coupling, hose, pres-
sure reducer, gas cylinder) are connected to
the system.
Screw the pressure reducer to the
<
gas cylinder by hand;
Insert the service coupling on the filling
<
connector;
Open the gas cylinder valve slowly and
<
fill the A/C system with forming gas 95/5.
The filling pressure is approx. 5 bar.
Start the engine briefly and use the
<
SelectH2 to start locating the leak, once
the leak has been found and the system
has been made leak-tight, we recom-
mend that you evacuate the system again
before filling with oil and coolant. Always
remember to observe the filling quanti-
ty specified by the manufacturer when
refilling! The test gas (forming gas 95/5)
is completely harmless for humans and
materials.
Warning: Observe the safety regulations
when handling the gas bottle - see the
label on the gas bottle.
