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.

Explanation
Warning advice, risk level according to the
signal word:
Warning! Serious physical injury may occur.
Caution! Slight physical injury or damage to
the equipment may occur.
> Implement the specified precautionary
measures.
Note: Basic or further information.

Elements of the instrument, the instrument
display or the program interface.
[OK] Control keys of the instrument or buttons of
the program interface.
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.
> Dangers may also arise from the systems being measured or
the measuring environment: 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.
> Make sure that your refrigeration system is properly earthed, as
otherwise the measuring instrument might get damaged.
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
testo 549 and testo 550 are digital manifolds for maintenance and
service work on refrigeration systems and heat pumps. They may
only be used by qualified authorized personnel.
The functions of the testo 549 and testo 550 mean they can replace
mechanical manifolds, thermometers and pressure/temperature
charts. Pressures and temperatures can be applied, adapted,
tested and monitored.

Operating valve positioner
The digital manifold acts like a conventional two-way manifold with
regard to the refrigerant path: The passages are opened by
opening the valves. The adjacent pressure is measured with valves
closed as well as with them open.
> Open valve: Turn valve positioner anticlockwise.
> Close valve: Turn valve positioner clockwise.
