9DTX10 - DTX80 USER GUIDE5. Start UpPlease read and understand the entire manual before operating the dryer.Check and read over wiring diagrams that pertain to your unit and make sure the correct power supply is connected,but do not energize circuit at this time. Provide proper short circuit protection. Follow all applicable codes.If you do NOT want the dryer to cycle automatically when energized, close the control air isolation valve. If thesystem has already been pressurized, bleed off the control air pressure by opening the knob on the bottom of thecontrol air filter and reclosing.Before starting the dryer your compressor should be running, your air system pressurized and the dryer bypassedand not yet pressurized.SLOWLY open the inlet isolation valve admitting compressed air to the dryer. It is important to pressurize the dryerslowly to prevent fluidization of the desiccant bed. The dryer outlet isolation valve should be closed at this time.SLOWLY open dryer outlet isolation valve. At this point all valves are in “normal” positions; air is flowing throughboth towers and downstream.Close the dryer bypass valve. Bypass valves must be bubble tight to prevent moisture from migrating around thedryer and contaminating the dry air outlet.It is required that the dryer be started without the mufflers installed. This will expedite removal of excess desiccantdust and prevent premature clogging of the exhaust mufflers.CAUTION: USE EAR AND EYE PROTECTION WHEN OPERATING DRYER WITHOUT MUFFLERS. EXCESSIVENOISE WILL BE CREATED. DUST AND PARTICLES FROM THE SURROUNDING AREA MAY BECOMEAIRBORNE. OPERATION WITHOUT MUFFLERS EXCEEDS OSHA LIMITS.Check the Variable Cycle Control setting. It should normally be set at the standard 10 minute, 100% load.Energize the electrical circuit. If the control air valve is open the dryer will begin to cycle.If the control air valve is closed, open it to begin the dryer cycle. At this point one tower will exhaust its air toatmosphere. See “CAUTION” statement above.Check and adjust the setting of the purge pressure indicator or purge flow meter in accordance with thespecifications for your dryer. Normally, purge flow is approximately 15% of design flow for the dryer. Note that evenif you are operating under a light load the purge can not be reduced if you are operating in the DDS or CycleLocmodes, or a fixed timed cycle other than the standard 10 minute, 100% load cycle.
