General information

The ATH AC134 eco is intended for professional use and should only be used by specialists or by a qualified

expert.

Because of the Chemical-Climate-Protection-Ordination of 2010 working on an air condition of motor vehicles may

be done only by persons, which are in possession of a certificate of competence. The minimum requirements for the

competence training are described in Regulation (EC) no. 307/2008.

In this context it should be noted that the competence requirements of the Federal Ministry for the Environment,

Nature Conservation and Nuclear Safety also apply to motor vehicle air-conditioning systems in commercial

vehicles, although the Regulatory Area of Regulation (EC) no. 307/2008 only on passenger cars and light

commercial vehicles is limited. In activities related to the recovery of refrigerants from motor vehicle air-conditioning

systems for automotive interior air-conditioning (passenger compartment and cab) in trucks, buses, construction

equipment and other commercial vehicles, a proof of competence on the basis of the requirements of Regulation

(EC) No. 307/2008 is required.

Disposal of the device

This device may not return to normal household waste, but it must be disposed of as hazardous waste.

The reuse or the right recycling of electrical and electronic equipment (EEE) is useful for the protection

of the environment and human health.

In accordance with the European WEEE Directive 2002/96 / EC are specific collection centers

available, where the waste of electrical appliances are to be transferred.

The public administration and the producers of electrical and electronic equipment shall endeavor to

facilitate the reuse and recycling processes of the waste of electrical and electronic equipment through

the organization of collection activities and through appropriate planning measures.

The law punishes those with appropriate sanctions, who illegally dispose of electrical and electronic

waste.

Safety instructions

It is necessary to wear suitable protective clothing such as gloves and goggles. The contact with the refrigerant

can cause blindness and other injuries. Read all service procedures and precautions, installation instructions

and operating instructions carefully. Failure to follow these precautions or improper use of the equipment may

result in property damage, personal injury, or death. Never allow untrained personal to perform these

procedures or to operate this device.

In case of rain or excessive moisture never use the device outside

You necessarily need to wear gloves.

You necessarily need to wear goggles.

Before using the AC134 eco read and understand the manual.

Avoid contact with the skin. The low boiling temperature (about -22 °F) may provoke freezing.

The room in which the AC134 eco is operated must be adequately ventilated.

While the machine is in operation, do not smoke.

While using the device keep the tubes away from rotating and hot elements such as ventilators,

radiators, etc.

Do not inhale the steam of the refrigerant gas.

While the device is operating, children and mentally disabled people should keep away.

Before the AC134 eco is connected to an ACD system or to an external tank, make sure that all valves

are closed.

Before turning off the AC134 eco be ensured that the stages are over and that all valves are closed.

Thereby, the leakage of the refrigerant into the outside air is avoided.

Do not change the setting of the safety valves and control systems.

Exclusively use external tanks or other storage tanks that are equipped with safety valves and that

have the necessary standards.

Put the AC134 eco in not-energized modus if it is not used. Before a long time of nonuse or before

servicing always disconnect the power supply

During maintenance, proceed with caution: in the tubes could be refrigerant under pressure.

Do not use the device in an explosive environment. Extraordinary maintenance interventions should

only be done by special personal.

For checking the consistence and pressure in the R134a devices or in the air-conditioning system of

the vehicle do not use compressed air. Some mixtures of air / HCF-134a can burn at high pressure.

Such mixtures are potentially very dangerous and may cause fire or explosions and subsequent

injuries or damages. For more information on safety measures and the protection of persons and

objects ask the manufacturer of coolant.

The device must always be placed in the normal standing position. When moving, the bottle must not

be shaken too much.

Work in a well-lit environment.

Do not inhale oil vapor or steam of the refrigerant. The steams may irritate the eyes and respiratory

tract. To remove residues of R134a on the A/C system only use the special recycling-units for R134a. If

refrigerant gets into the outdoor air, ventilate the working area well before you start working again.

6 / 36

Do not use the device in direct sunlight; sun exposure can cause excessive temperatures and

malfunctioning. The operating temperatures indicated refer to device that is protected from direct

sunlight.

Maintenance on the AC system should only be performed by trained personnel. The liquids required

must be specified by the manufacturer. ATH-Heinl GmbH & Co.KG accepts no responsibility for any

direct or indirect damage caused by incorrect operation.

Warning!

Work far away from open flames and hot surfaces; high temperature causes the decomposition of the

refrigerant so that toxic and irritant substances are emitted. That is harmful to the operator and environment.

Attention!

Make sure that the refrigerant does not get in the environment during the execution of the various operations.

This is in line with international environmental standards. It is avoided that the refrigerant in the room makes it

difficult to locate leaks.

Attention!

The AC134a eco may not be used for air-conditioning that have the R12 as refrigerant.

Introduction

With the advanced technology of the ATH AC134 eco the use in all air conditioners installed in cars, trucks and

industrial vehicles with R134a refrigerant is extremely easy. It is an easy-to-use and reliable air conditioner. The

processor-controlled AC134 eco enables the management of all functions via electronic scales, have electronically

controlled solenoid valves (measured values in weight or minutes and help messages of the selected cycles), via a

control panel with pressure gauges and a LCD display.

The connection of the AC134 eco with an A/C system allows recovering and recycling the refrigerant that is returned

to the system after evacuating.

The amount of oil that was taken during the recovery of the refrigerant of the A/C system can be measured and

subsequently refilled.

The AC134 eco is equipped with a two-stage high vacuum pump and a pressure measurement group (gauge); this

pressure measurement group let you see continuously the ongoing operations. The pressure of the refrigerant tank

is monitored and regulated electronically.

The tightness-test in the air-conditioning system is performed by the pressure gauge and the LCD display

program of the plant itself.

The AC134 eco is equipped with special connectors to avoid the risk of contamination with other units which are using

R12 as refrigerant.
