About this document

i Please read this documentation through carefully and familiarize yourself with

the product before putting it to use. Keep this document to hand so that you can refer to it when necessary. Hand this documentation on to any subsequent users of the product.

i Pay particular attention to information emphasized by the following symbols:

· With the signal word

Warning!

: Warns against hazards which could result in serious physical injury if the precautionary measures indicated are not taken.

· With the signal word

Caution!

: Warns against hazards which could result in minor physical injury or damage to equipment if the precautionary measures indicated are not taken.

· Important information!

Avoiding personal injury / damage to equipment

i Do not make measurements with the measuring instrument and its sensors

on or near live components unless the instrument is expressly approved for current/voltage measurements!

i Never store the measuring instrument together with solvents and do not use

any desiccants.

i Only operate the measuring instrument properly, for its intended purpose

and within the parameters specified in the technical data. Do not use force.

i Only carry out the maintenance and repair work that is described in the

documentation. Follow the prescribed steps when doing so. Use only OEM spare parts from Testo.

Safety and the environment 5

Warning!

Danger of injury exists if highly pressurized hot, cold and/or toxic refrigerants escape. For this reason, always wear protective glasses and protective gloves when carrying out measurements and other work on the refrigeration system.

If the measuring instrument falls down or is exposed to any other comparable mechanical strain, the end connections of the refrigerant hoses can break off. The valve knobs can also be damaged, which can lead to further damage in the interior of the instrument, which is not visible externally. For this reason, replace the refrigerant hoses after any fall or comparable mechanical strain with new, undamaged refrigerant hoses. For your own safety, send the instrument to Testo customer service for technical testing.

Protecting the environment

i Refrigerant gases can harm the environment. Please note the applicable

environmental regulations.

i Take faulty rechargeable batteries / spent batteries to the collection points

provided for them.

i Send the product back to Testo at the end of its useful life. We will ensure

that it is disposed of in an environmentally friendly manner.

Specifications

Functions and use

testo 556 and testo 560 are refrigeration system analyzers for maintenance and service work on (large) refrigerating systems and heat pumps. The testo 560 furthermore offers a vacuum function for commissioning work. The instruments may only be used by qualified authorized personnel.

With their functions, the testo 556 and the testo 560 replace mechanical manifolds, thermometers and pressure/temperature tables. Pressures and temperatures can be loaded, adjusted, tested and monitored.

The range of functions can be expanded through comprehensive, separately available accessories, e. g.: Various temperature probes (also radio probes), clamp-on probe*, refrigerant scale*, oil pressure probe*, PC software.

testo 556 and testo 560 are compatible with most non-corrosive refrigerants, water and glycol. testo 556-1 and testo 560-1 are not compatible with refrigerants which contain ammonia.

The product must

not

be used in areas at risk of explosion!

* Option not available as standard. Please ask your local Testo subsidiary.
