Note: Do not over tighten hoses on to manifold gauge set. The most valuable information about the manifold gauge set is it could read a pressure and temperature of refrigerant in a close system. 0000173900 00000 n 0000031052 00000 n 0000194300 00000 n 0000087763 00000 n A refrigeration manifold gauge set is used for measuring the pressure in HVAC units so they can be evaluated or an effective troubleshoot can be conducted. The extra connections that go to nothing also keep the hoses from getting tangled and easy to store away. the. 0000117794 00000 n The low-pressure side goes to the blue port on the gauge. /BaseFont /Times#20New#20Roman Caution: Never open the high side valve on manifold gauge set when the A/C System is operating. A manifold gauge set will have red, blue, and yellow hoses. Search fo shoe. 0000172845 00000 n If you want to join this industry as a technician, now is a good time. The analog (indicator needle) is the most common on the market. All HVAC gauges set read the same way. MANIFOLD GAUGES (°F and °C) RED AND BLUE With 1% accuracy (Class 1) calibration Gauges are completely fi lled with glycerin for maximum protection from pulsation. The red and blue hoses go straight to the red and blue gauges while the center yellow hose is separate. 0000118538 00000 n However, I couldn’t label all of it, so we only see zero to 100 psi in The yellow hose is going to the refrigerant bottle and the red hose going to the unit.
