Alarm Events and Descriptions The MCH36 Silent Touch dashboard has 55 different alarm states. Each alarm condition has a unique name and associated definition. Alarm names and definitions are factory set. When an alarm event threshold is reached, the button color turns yellow and the system will either (a) sound an alarm, and/or (b) shut down the compressor. - Page 19 MCH36 Silent Touch 1ST STAGE PSI HIHI The first stage pressure is critically high. The system shuts down immediately and sounds an alarm. 1ST STAGE PSI LO The first stage pressure is low and requires evaluation. Alarm sounds. 1ST STAGE PSI LOLO The first stage pressure is critically low.

Page 26: Storing Technical Documentation
Tampering with the safety valve to increase the pressure setting is strictly forbidden. Tampering with the safety valve can seriously damage the compressor, cause serious injury to personnel, and renders the warranty null and void. Should the safety valve fail to work properly, contact Nuvair Technical Support. -
Page 27: Gauge Matrix
The gauge matrix (Figure 17) is described below, from top row—left to right—and the bottom (final pressure) gauge. The compressor front panel has a total of six (6) mechanical gauges. The Nuvair MCH36 Silent Touch model monitors all gauge pressure readings electronically in the Dashboard where alarms and shutdowns are programmed in by the factory. -
Page 28: Presec System
MCH36 Silent Touch 10.4 PRESEC System The PRESEC system's is a visual filter element moisture indicator system. Its wired probe is connected to the compressor's final filter tower and provides visual indicators of the moisture level in the filter element based on electrical conductivity of the moisture. - Page 29 MCH36 Silent Touch During tank refill, those not involved in the refill procedure must maintain a safety distance of at least 9 feet (3 meters). Also, it is forbidden to disconnect the hoses from the fittings or the high-pressure out connection while the machine is under pressure.

100 hours of use or annually, whichever comes first. HP Compressor Lubricant: Only use lubricants rated for use with nitrox, such as Nuvair 455™ or Nuvair 751™. Never mix compressor lubricants. Nuvair compressors are shipped with Nuvair 455 synthetic food grade lubricant (for breathing air use) or Nuvair 751 (for industrial use). -
Page 33: Checking The Oil Level
MCH36 Silent Touch Do not carry out these tasks if the compressor has only just shut down; wait for the compressor to cool. Pressure must be drained before opening LP fill plug. Any oil spilt during the oil/filter change could cause personnel to slip; wear protective garments and anti-slip footwear and remove traces of oil immediately. -
Page 34: Changing The Lubricating Oil And Filter
According to Coltri specifications, a new compressor using synthetic lubricants can operate up to 1000 hours between oil changes. At Nuvair, we prefer to have oil changed every 250 hours (or once per year, whichever interval is less) unless you are taking advantage of an oil analysis program that confirms the oil is still good. -
