WARNING
1.1 The mainfold has been designed specially to measure pressure in refrigeration
equipment. The mainfold may only be used by trained technicians.
1.2 It must not be used for other than refrigeration applications. The manifold is not
suitable for liquids or gases other than those indicated on the gauge.
1.3 It must not be used with pressures higher than the pressure scale indicated on
the high-pressure gauge of the manifold.
1.4 Safe goggles and gloves must be worn at all time during the use of the mainfold.
1.5 The gauges are correctly calibrated at the factory before shipment. If calibration is
required, remove the plastic plug on a sight glass and insert a small flat
screwdriver into the opening to adjusting screw for calibration.
1.6 Clean up the connection interfaces in order to prevent contamination entering to
refrigeration system.
1.7 The charging hoses must be checked with oil residue cleaned off before each
use. A visible check is also necessary to ensure that the hoses and the
connection are undamaged and tight.
1.8 Do not contact refrigerant directly as it may cause personal injury.
1.9 Do not vent refrigerant into the atmosphere.
1.1 o The seals and gaskets of the manifold gauges are parts subject to the wear and
tear of use, and must therefore be replaced from time to time. The manifold is to
be tested regularly to ensure the valves are still tight.
1.11 Make sure to use the right pressure gauge.
1.12 Mainfolds are high precision measuring instruments. After use, disconnect all
hoses from the system and open valves and then store the mainfold always in the
carrying case.
1.13 Dispose of the used manifold gauges according to the local rules and
regulations.
