claim to be comprehensive.
The product is intended only for the highly specific usedescribed in the user manual.
The most important prerequisites and safety measures for the use and operation of
the product are also described to ensure faultless operation.
No warranty can be given and no liability is assumed for applications exceeding the
described intended use, irrespective of observance of the necessary prerequisites
and safety measures.
The product must only be used and operated by instructed personnel who, based
on their qualifications, are capable of adhering to the necessary safety measures
during use and operation. Only accessories and consumables supplied by AVL
DiTEST or approved by AVL DiTEST must be used. The measurement results
obtained from the product in question depend not only on the correct functioning of
the product, but also on a series of general conditions. The results delivered by the
product must therefore be evaluated by a specialist (e.g. plausibility check) before
further action is taken on the basis of a delivered measurement.
Adjustment and maintenance works on open live devices may only be performed by
trained specialists who are aware of the associated danger.
The product may onlybe repaired in the factory of origin or by specialists specifically
trained to perform such repair.
When using the product, it must be ensured by a specialist that the test object or

User Manual
V
SAFETY INSTRUCTIONS FOR CARBON DIOXIDE CO2
(R744)
Always observe the manufacturer's safety data sheet
WARNING
Contact with the product can cause cold burns or frostbite.
Gases/vapours are heavier than air. High concentration due to accumulation in closed
rooms, work pits, cellars, etc. can cause asphyxiation, among other things. Symptoms:
Loss of motor ability and consciousness. Affected persons do not realis that they are
suffocating.
Do not allow carbon monoxide to enter sewage systems, pits or similar enclosures where
gas accumulation may be dangerous.
Precautions and behaviour rules
WARNING
Storage: Store container in a well-ventilated place at a temperature below 50 °C.
Protect container against impacts and falls (secure with chain).
Handling: Avoid contact with eyes and skin. Do not inhale the gas. Ensure that no water
enters the gas cylinder/container.
Prevent the gas from flowing back into the gas tank. Only use equipment that is suitable
for this product and the intended pressure and temperature. Check fittings, connections
and lines for leaks. Eating, drinking and storing food in the working area are prohibited.
Respiratory protection: Self-contained breathing apparatus.
Eye protection: Tightly fitting protective goggles.
Hand protection: Protective gloves (material: leather).
Body protection: Protective clothing.

gear and self-contained breathing apparatus. Close valves / stop gas leak. Avoid entry into
cellars, pits and similar enclosures (danger of suffocation).
In case of fire: Wear protective gear and self-contained breathing apparatus. Stop gas
leak if possible. Cool cylinders with a water jet from a secure position and remove them
from the fire zone if possible to prevent explosion. The product itself is non-flammable.
Extinguishing agents: All known extinguishing agents can be used.
Escape routes: Escape routes must be known to staff.
Accident phone: The accident phone must be known to staff.
First aidPlease observe the instructions for use and safety instructions of your
refrigerant supplier.

SAFETY INSTRUCTIONS FOR NITROGEN N2
Always observe the manufacturer's safety data sheet
WARNING
High concentrations of the gas can cause suffocation.
Loss of motor ability and consciousness.
Rapid release of large quantities creates cold and fog.
Gas may accumulate in cellars, pits, etc., because it is about as heavy as air.
Container may burst or explode in the event of a fire.
Precautions and behaviour rules
WARNING
Employees must be instructed in the use of the gas before being allowed to work with it.
Do not inhale cylinder gas.
Secure cylinders from falling over.
Ensure good ventilation when working.
Filter masks do not protect against asphyxiation.
Wear protective gloves when transporting the cylinder.
Use the cylinder trolley.
Never open valves forcibly (no pliers, etc.)
Store cylinder in well-ventilated location at a temperature <50 °C.
Only use suitable equipment (pressure/temperature/product).
Ensure that no water can enter or flow back into the gas cylinder.
Always close cylinders, even if they are empty, before transporting them and secure with
lock not and protective cap.
Lash down cylinders when transporting them in a vehicle. The loading space should be
separate from the driver's cab and have vents in the ceiling and floor areas.

Behaviour in the event of danger
WARNING
Exposure to heat and fire may cause cylinders to burst/explode.
All extinguishing agents can be used.
If gas is escaping, close valve is possible.
Make sure that the gas does not enter cellars, recesses, pits, etc. where gas accumulation
might be dangerous (danger of suffocation).
Fire: Remove container from the danger zone or, if this is not possible, cool it with water
from a safe distance.
Ensure good ventilation.
In case a large quantity is released or in confined spaces: Evacuate area and enter only
with self-contained breathing apparatus. Re-entry only after verification of safe level.
First aidPlease observe the instructions for use and safety instructions of your

SAFETY INSTRUCTIONS FOR WORKING ON AIR
CONDITIONING SYSTEM
WARNING
The device must not be used if the heating band or cable is damaged. Contact the
respective AVL DiTEST branch / AVL DiTEST partner in your country.
NOTICE
The oil level of the vacuum pump must be checked regularly. Top up if necessary. After
60 operating hours a regeneration of the pump oil is necessary (user notification). The
regeneration can be performed from the maintenance menu. After 500 operating hours
or one year, the pump oil must be changed (user notification). Oil changes can also be
performed via the maintenance menu. The pump oil will also be changed as part of the
annual servicing of the device by the service partner.
NOTICE
A device check is performed automatically once a week. It can also be triggered
manually in the maintenance menu. The device check ensures that the system is sealed
and all components are operating correctly. In case of a malfunction, the device will
have to be serviced.
NOTICE
The filling level of the oil container must be checked at regular intervals. Full used-oil
containers must be emptied. Empty clean-oil medium bottles must be refilled if
necessary.

User Manual
NOTICE
Check the available printer paper and replace the paper roll if necessary.
NOTICE
We recommend that you have the device serviced by your service partner once a year.
As part of every servicing the vacuum pump oil is changed and the calibration checked.
If necessary, a recalibration is performed.
NOTICE
The ADS 340 may only be operated on a level and solid foundation. The refrigerating
agent cylinder must be upright in the device. Any tilting may result in incorrect
measurements by the cylinder scales and thus incorrect filling quantities.
NOTICE
Open the manual valve of the connected refrigerating agent cylinder before switching
on.
If the ADS 340 is not being used, shut of the gas supply by closing the manual valve.
NOTICE
The ADS 340 performs a self-test when it is switched on. This is indicated by the brief
sounding of the siren.
NOTICE
If the ADS 340 is not used for a prolonged period, the manual valve must be closed.

GENERAL SAFETY INSTRUCTIONS
WARNING
Read all instructions carefully.
DANGER
Danger of life due to electrical voltage
The cylinder heater is operated via the mains voltage.
Only connect/disconnect the ADS 340 when it is switched off.
WARNING
Danger from hot parts
The cylinder heater and the refrigerant cylinder become hot during operation.
Assembly gloves have to be worn while operating the cylinder valve and changing
cylinders.
WARNING
Change the gas cylinder only with assembly gloves. When changing the gas cylinder,
touching with unprotected hands the not yet installed gas cylinder with connected heating
cable and the air conditioner with unprotected hands can cause an unpleasant but
harmless electrical discharge.
CAUTION
The weight can result in persons or body parts being trapped. Ensure wheel brakes are
applied during operation. Ensure that there is a minimum distance of 1.5 m to walls.
