General safety instructions
•Always operate the product properly, for its intended purpose and within the
parameters specified in the technical data. Do not use any force.
•Do not commission the instrument if there are signs of damage on the
housing.
•Dangers may also arise from the systems being measured or the measuring
environment: Make sure you comply with the locally valid safety regulations
when carrying out measurements.
•Do not expose the product to temperatures above 50 °C (122 °F).
•Do not store the product together with solvents. Do not use any desiccants.
•Only maintenance and repair work that is described in the documentation
may be carried out on this instrument. Follow the prescribed steps exactly
when doing the work. Only use original spare parts from Testo.
Built-in rechargeable battery
DANGER
Risk of death!
The built-in rechargeable battery can explode if it gets too hot.
-Do not expose the product to ambient temperatures above 50°C.
•Battery cover must always be closed while operating.
•Improper use of batteries may cause destruction of the batteries, injuries due
to current surges, fire or the escape of chemicals.
•Do not deform batteries. Batteries must not be squashed, drilled, dismantled,
pierced, modified or damaged in any other way. This may lead to the
leakage of battery acid, to the escape of gases and/or to an explosion.
•Do not heat batteries above the permitted temperature or burn them. If a
battery is heated, this may lead to the leakage of battery acid and/or to an
explosion. Lithium batteries can, for instance, react very strongly in
combination with fire. This may involve battery components being emitted
with considerable power.
•Do not consume the battery; risk of burns due to hazardous substances.
Keep new and used batteries away from children.

2 Safety and disposal
7
•In principle, contact with escaping battery components may present a risk to
health and to the environment. Adequate body and respiratory protection is
therefore required when in contact with batteries that exhibit abnormalities
(escaping contents, deformations, discolourations, dents or the like).
•Batteries must be disposed of in accordance with the local and country-
specific regulations. In order to prevent short circuits and the associated
heating, lithium batteries must never be stored unprotected in bulk.
Appropriate measures against short circuits are, for instance, inserting the
batteries into the original packaging or a plastic bag, masking the poles or
embedding them in dry sand.
•Lithium batteries must be transported and shipped in accordance with the
local and country-specific regulations.
•If there is any contact with the skin or eyes, the areas must be rinsed with
water for at least 15 minutes. If there is any contact with the eyes, a doctor
must be contacted in addition to the rinsing.
•If burns are caused, these must be treated appropriately. You are also
strongly advised to contact a doctor.
•Airways: leave the room immediately when smoke development or gas
release is acute. Consult a doctor when amounts are larger and airways are
irritated.
•Swallowing: rinse out mouth and surrounding area with water. Get medical
assistance immediately.
2.1 Product-specific information
ACHTUNG
The measuring instrument being dropped or any other comparable
mechanical stress may cause breakage of the pipe pieces in the
refrigerant hoses. The valve positioners may also suffer damage,
causing further damage inside the measuring instrument that is not
necessarily visible externally.
-Therefore, always replace the refrigerant hoses with new ones after
the measuring instrument is dropped or after any comparable
mechanical stress.
-For your own safety, you should return the measuring instrument to
the Testo Customer Service for technical inspection.
ACHTUNG
Electrostatic charging may destroy the instrument.
-Integrate all the components (system, manifold's valve block,
refrigerant bottle, etc.) into the potential bonding (earthing).
-Please see the safety instructions for the system and the refrigerant
used.

VORSICHT
Refrigerant gases can harm the environment.
-Please note the applicable environmental regulations.
Explosion hazard when using A2, A2L and A3 refrigerants
During maintenance and repair work on refrigeration systems with flammable
refrigerants (e.g. category A2L, A2 and A3 of ISO 817), a hazardous and
explosive atmosphere must always be expected in the immediate vicinity of the
system. The testo 570s may only be operated outside of designated,
recognizable or assumed explosion hazard zones (acc. to IEC 60079-10-1).
The following occupational safety measures must be observed to avoid a
hazardous explosive atmosphere (see also: TRBS 1112, TRBS 2152 and VDMA
24020-3):
•Wear protective goggles and gloves.
•Before applying pressure to the measuring instrument: Always attach the
measuring instrument to the suspension device to prevent it from falling
down (risk of breakage).
•Before each measurement, check that the refrigerant hoses are intact and
correctly connected.
Do not use any tools to connect the hoses, only hand-tighten the hoses
(max. torque 5.0 N∙m / 3.7 ft∙lb).
•Adhere to the permissible measuring range (-1...60 bar/-14.7...870 psi).
Pay particular attention to this for systems with refrigerant R744, as these
are often operated at higher pressures!
•Open and close valves on the unit in the correct sequence to prevent any
leakage of refrigerant from the system throughout the commissioning,
maintenance and repair period.

2.2 Disposal
•Dispose of faulty/spent batteries in accordance with the valid legal
specifications.
WEEE Reg. Nr. DE 75334352
•At the end of its useful life, deliver the product to the separate collection
point for electric and electronic devices (observe local regulations) or return
the product to Testo for disposal.
3 Product-specific approvals
For the relevant country approvals, please refer to the printed quick reference
guides or short instructions enclosed with the products.
4 Intended use
The measuring instrument testo 570s is a digital manifold for maintenance and
service work on refrigeration systems that are set up, maintained and operated
in accordance with the provisions of EN 378:2021-06 Part 1-4. It may only be
used by qualified personnel.
The safety instructions in the operating manual of the refrigeration system, the
refrigerant manufacturer and the measuring device must be followed.
The functions of the instrument testo 570s mean it can replace mechanical
manifolds, thermometers and pressure/temperature charts. Pressures and
temperatures can be applied, adapted, tested and monitored.
With its integrated logging function the device can be left on the system and
logging can be done without being on site.
The combination of rechargeable battery and exchangeable batteries allows
dual power operation.
The instrument testo 570s is compatible with most non-corrosive refrigerants,
water and glycol. The instrument testo 570s is not compatible with refrigerants
containing ammonia.
The testo 570s must not be used out of specified pressure and/or operation
temperature range.
The product must not be used in potentially explosive atmospheres!
WARNUNG
Under no circumstances should the manifold be used as a pressure
reducing valve, especially when nitrogen N2is used.
