DUAL ONBOARD AIR SYSTEM DUAL AIR COMPRESSOR INSTALLATION (CONT’D) Guidelines for Selecting Mounting Location: The selection of proper mounting location for your air compressor will help ensure a long and trouble free compressor service life. Please pay close attention to the following: - Select a FLAT, UPRIGHT & SECURE LOCATION where the compressor can be mounted.
DUAL ONBOARD AIR SYSTEM OPERATING INSTRUCTIONS IMPORTANT: The compressors have a maximum working pressure of 150 PSI (P/Ns 20011, 20015, 20016 & 20017) or 200 PSI (P/Ns 20013, 20014, 20019 & 20020). Always operate the compressor at or below the MAXIMUM PRESSURE RATING of the compressor. Operation exceeding maximum pressure ratings and or duty cycle will result in damage to air compressor. 1. Your air compressor is equipped with an AUTOMATIC THERMAL OVERLOAD PROTECTOR.
DUAL ONBOARD AIR SYSTEM DASH PANEL GAUGE INSTALLATION Your VIAIR Onboard Air System comes complete with a Dash Panel Gauge to monitor the pressure of your VIAIR air tank. Additionally, the Dash Panel Gauge has an ON/OFF switch preinstalled that will allow you to turn the system off by cutting power to the pressure switch with relay that you have already installed.
