equipped with a safety pressure relief in case of a pressure build up inside the gauge
due to a defect. The hoses can be hooked up to the hose anchors on the side and at the
front of the t-style for storage. 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 refri-
gerants 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.
