HANDLING METHOD AND STRUCTURE
Manifold gauge
The manifold gauge is used to measure the operating pressure accurately in the high pressure and low pressure lines of the refrigerating system. The high pressure gauge measures from -101.3 kPa (-1,013 mbar, -760 mmHg, -29.92 inHg) to 2,942 kPa (29.4 bar, 30 kg/cm², 427 psi), and the low pressure gauge measures generally from -101.3 kPa (-1,013 mbar, -760 mmHg, -29.92 inHg) to 1,471 kPa (14.7 bar, 15 kg/cm², 213 psi).
CAUTION
When installing the gauge to the refrigerating system, use utmost care not to mistake high pressure and low pressure line connections. (Wrong connections will lead to a damaged gauge.)
Before evacuating, confirm that the gauge has a negative pressure scale. (If not, the gauge will be damaged.)
