Safety instructions Before using the device, please read carefully this user manual. It delivers important information about the device operations, maintenance and storage. 1.1 General warnings about the device · Interior and exterior use. · Respect the measuring ranges of the probes and hoses connected to the device. · This device has been developed and produced to be sold exclusively to trained and qualified HVACR technicians and engineers. Appropriate training might be necessary in order to ensure safe use of this instrument. Sauermann is not responsible for any possible accident during its use. · Please always use the device in accordance with its intended use and within parameters described in the technical features in order not to compromise the protection ensured by the device. · When using the device, the safety of the system integrating the device is the responsibility of the system assembler. · This device can pose a risk for pacemaker wearers. Respect a distance of at least 10 cm (4") between the device and the wearer. · Respect a safety distance with other electronic devices like computers, credit cards, computer or TV screens which could be damaged by the magnetic field of the apparel. · Only the accessories provided with the device or available as an option must be used. · Do not use the device if it is damaged or if it operates abnormally. Inspect the device before every use. In case of doubt, please contact Sauermann's After-sales service. · Do not authorize pressures beyond the device limits. Please refer to the technical features described in this user manual. · The device must not be exposed to rain or any other humid environments (> 85 %RH) without using a proper protection. · Do not use the device next to explosive and corrosives gases, vapours or dust. · Do not place your fingers in movable zones of the device (articulations). · The device must not be used in ATEX zones according to applicable standards. · Do not store the device with solvents. Do not use desiccants. Do not use isopropanol. · During use, keep inspecting the device and accessories for effective operation and your own safety. · Do not give this product to a child. · If the device falls or in case of similar inconveniences, or if an irregular malfunction appears, please send back the device to Sauermann's After-sales service for a technical check and to ensure your own safety. 1.2 Warnings about the manifolds Refrigeration systems using flamable gases (A2L, A2 and A3 categories) are expected to be in hazardous and ex- plosive areas. The manifold must operated outside of designated, recognizable or assumed explosion hazard areas (according to IEC 60079-10-1). Refrigeration system Explosive area Safety instructions Non-explosive area 5 · The manifold should be used in a well ventilated area. · Respect the pressure measuring range (-1 to 60 bar / -14 to 870 psi), especially for systems with refrigerant R744, as these are often operated at higher pressures. · Overload pressure maximum: 65 bar (943 psi). The device must not be used with ammoniac refrigerant gas (NH3 / R717). · Open and close valves on the manifold in the correct sequence to avoid any leakage of refrigerant from the system throughout the commissioning, maintenance and repair period. · This device has been developed to measure simultaneous parameters including pressure, vacuum and temperature measurements. It must not be used in any other purpose. · Always use the hook to attach the manifold to prevent it from falling (risk of breakage) before applying pressure · 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: ??) · The user of the manifold shall be protected against electrostatic discharges and discharge from static electricity from its body by being in contact with grounded metallic object or by using an anti-ESD equipment. · Always wear protective glasses and gloves when using the device in order to protect your eyes and skin when operating refrigerant gases. The vapours of refrigerant gases are extremely cold. Do not expose your skin to these vapours. 1.3 Environment protection Send back the device at its end of working life for waste collection center of electrical and electronic components (according to local regulations), or send it back to Sauermann to ensure a required waste collection in the respect of the environment. Refrigerant gases can harm the environment. Please comply with current legislation on refrigerant gases about environment protection. 1.4 Symbols used For your safety and in order to avoid any damage of the device, please follow the procedure described in this user manual and read carefully the notes preceded by the following symbol: The following symbol will also be used in this user manual: Please read carefully the information notes indicated after this symbol. © 2025 SAUERMANN.
