2.1. About this document

Use

> Please read this documentation through carefully and

familiarize yourself with the product before putting it to use. Pay particular attention to the safety instructions and warning advice in order to prevent injuries and damage to the products.

> 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.

the equipment may occur. > Implement the specified precautionary

measures.

2.2. Ensure safety

> Do not operate the instrument if there are signs of damage at

the housing, mains unit or feed lines.

> Do not perform contact measurements on non-insulated, live

parts.

> Do not store the product together with solvents. Do not use any

desiccants.

> Carry out only the maintenance and repair work on this

instrument that is described in the documentation. Follow the prescribed steps exactly. Use only original spare parts from Testo.

> The objects to be measured or the measurement environment

may also pose risks: Note the safety regulations valid in your area when performing the measurements.

> If the measuring instrument falls or another comparable

mechanical load occurs, the pipe sections of the refrigerant hoses may break. The valve positioners may also be damaged, whereby further damage to the interior of the measuring instrument may occur that cannot be identified from the outside. The refrigerant hoses must therefore be replaced with new, undamaged refrigerant hoses every time the measuring instrument falls or following any other comparable mechanical load. Send the measuring instrument to Testo Customer Service for a technical check for your own safety.

> Electrostatic charging can destroy the instrument. For online

measurement (instrument connected to PC/laptop) or when using the mains unit in particular, you should therefore integrate all components (system, valve manifold of the manifold gauge, refrigerant bottle, etc.) into the equipotential bonding (earthing system) prior to measurement. Please see the safety instructions for the system and the refrigerant used.

2 Safety and the environment

2.3. Protecting the environment

> Dispose of faulty rechargeable batteries/spent batteries in

accordance with the valid legal specifications.

> At the end of its useful life, send the product to the separate

collection for electric and electronic devices (observe local regulations) or return the product to Testo for disposal.

> Refrigerant gases can harm the environment. Please note the

applicable environmental regulations.

3.1. Use

The testo 570 is a digital manifold for commissioning, maintenance and service work on refrigeration systems and heat pumps. It can be used for fault diagnose and online measurements on refrigeration systems and heat pumps. The testo 570 is only to be used by qualified expert personnel.

With its functions the testo 570 replaces mechanical manifolds, thermometers and pressure/temperature charts. Pressures and temperatures can be applied, adapted, tested and monitored.

Its scope of functions can be considerably extended by means of extensive, separately available accessories, e.g. various temperature sensors, clamp probe, oil pressure probe, PC software.

The testo 570 is compatible with most of the non-corrosive refrigerants, water and glycol. The testo 570 is not compatible with ammoniac refrigerants.
