Manifold Gauge Instructions
Purpose and use
The manifold have been designed especially to measure pressure in refrigeration equipment. The manifold may only be used by trained technicians The manifold must not be used for other than refrigeration applications in connection with refrigerants. The manifold is not suitable for other liquids or gases than those indicated on the gauge.
The manifold must not be used with pressure higher than the pressure scale Indicated on the high pressure gauge of the manifold.
The manifold can in no case be used as a pressure regulator.
Safety gaggles and gloves must be worn at all time during the use of the manifold.
Technical deception
The 2-way manifold is a high precision instrument. Both gauges, high and ow pressure can be readjusted to the zero point. The manifold gauges are marked with temperature and pressure scales or are equipped with interchangeable refrigerant scales.
Changeable piston type valves ensure prefect sealing, Glycerine – oli filled gauges are equipped with a safety pressure relif in case of a pressure build up to the hose anchors on the side and at the front of the T-style for storage during non use. This Protects the hoses against contamination or damage.
Use of manifold Preparing
Before use ensure that the temperature scales on the manifold gauges match the refrigerants used in the system.
Adjust the gauge with the zero adjusting screw to zero. Position of the hand may vary and might not point to zero depending on the atmospheric pressure.
Readjusting the gauge might therefore be necessary before each use of the manifold. The zero adjusting screw is positioned either at the top or through the front lens depending on the type of manifold.
