Failure to comply can result in personal injury and/or system damage.  \nWARNING: The OMB/C operates by using a strong magnetic sensor. It is important to keep the control free of any steel or iron particles which could accumulate on it during installation. These may hamper or prevent the control from operating.  \n1. Read installation instructions thoroughly. Failure to follow instructions may result in product failure, system damage, or personal injury.  \n2. Do not open system under pressure.  \n3. Ensure supply voltage is within specified OMB/C limits.  \n4. Disconnect supply voltage from system/OMB/C before installation/ service. Comply with local electrical regulations when wiring OMB/C.  \n5. Do not exceed maximum working pressure.  \n6. Keep temperature within nominal limits.  \n7. Work should be performed by qualified service personnel or a licensed contractor.  \n\n| SPECIFICATIONS | OMB | OMC | OMC NH3 | OMC CO2 |\n| --- | --- | --- | --- | --- |\n| Maximum Working Pressure (MWP) | 870 psig |  |  | 1885 psig |\n| Solenoid min/max OPD | 0/350 psig |  |  | 0/1450 psig |\n| Supply Voltage | 24V, 50/60 Hz | 120V, 220-240V,\u003Cbr>50/60 Hz | 24V, 120V, 220-240V\u003Cbr>50/60Hz |  |\n| Solenoid Coil | EMF |  |  |  |\n| Current Consumption | 0.6 Amp (24V) | 0.15 Amp (120V),\u003Cbr>0.07 Amp (220-240V) | 0.6 Amp (24V), 0.15 Amp\u003Cbr>(120V), 0.07 Amp (220-\u003Cbr>240V) |  |\n| Time Delay for Low Level Signal | 10 seconds |  |  |  |\n| Time Delay After Setpoint Recovery | 5 seconds |  |  |  |\n| Alarm Delay Time (Including Alarm Contact) | 120 seconds |  |  |  |\n| Alarm Switch | SPDT |  |  |  |\n| Alarm Contact Rating | 10A @ 120VAC 50/60 Hz, 5A @ 250VAC 50/60 Hz, 3A @ 30VDC |  |  |  |\n| Refrigerant Compatibility | Class A1 (incl. subcritical CO2) |  | Ammonia | Transcritical\u003Cbr>CO2 |\n| Refrigerant Temperature | -40° to 180°F Maximum |  |  |  |\n| Ambient Temperature-Storage | -40° to 120°F Maximum |  |  |  |\n| Ambient Temperature-Intermittent Duty | -40° to 120°F Maximum |  |  |  |\n| Oil Supply Fitting | 1/4\" Male SAE |  |  |  |\n|  | (Brass) |  | (Stainless\u003Cbr>Steel) | (Brass) |\n\nINSTALLATION INSTRUCTIONS  \n1.

See adapter kit instruction sheet (PA-00316) for choosing proper adapter and installation instructions.  \n3. O-ring replacement kit (KS-30368) can be used on the OMB, OMCand W-OLC controls.  \n4. If replacement of OMB or OMC is required, replace like for like.  \nOMC  \nINSTRUCTIONS FOR FIELD CHANGEOUT OF  \nOMB OR OMC OIL CONTROL  \nThis instruction has been developed to minimize down time based upon actual field experience. Read through the entire instruction before proceeding with the change-out.  \nIMPORTANT: Do not remove the control box from the valve body for any reason. This will damage the control and cause the Hall-effect sensor to lose calibration. Do not use the control as a step. The solenoid coil is not replaceable; the entire control must be replaced.  \nTools Recommended: 7/16\" nut driver; 7/16\" open-end wrench; adjustable wrench; slotted screwdriver; wire stripper; manifold gauge set; refrigeration valve wrench (Additional items which may be required depending on applicati","cbCaisCnDHwqtEeE","https://ap.wps.com/l/cbCaisCnDHwqtEeE","pdf",498702,"English","# FEATURES\n# SAFETY INSTRUCTIONS\n# SPECIFICATIONS\n## OMB\n## OMC\n## OMC NH3\n## OMC CO2\n# INSTALLATION INSTRUCTIONS\n## Tools Recommended\n## Field Changeout of OMB or OMC Oil Control","[{\"question\":\"What safety precautions are required before opening or servicing the system?\",\"answer\":\"Ensure system pressure is brought to and remains at atmospheric pressure.
