2 RECEIVINGThis shipment has been thoroughly checked, packed and inspected before leaving our was received in good condition by the carrier and was so for Visible Loss or this shipment shows evidence of loss or damage at time of delivery to you, insist that a notation of this loss or damage be madeon the delivery receipt by the carrier s UNPACKINGC heck for Concealed Loss or a shipment has been delivered to you in apparent good order, but concealed damage is found upon unpacking, notify thecarrier immediately and insist on his agent inspecting the damage claims are not our responsibility as our terms are point of MOVING In moving or transporting dryer , do not tip dryer onto its STORAGEIMPORTANT - Do not store dryer in temperatures above 130 F, C.

3 GENERAL SAFETY INFORMATIONFor Sales & Service contact: CENTRAIR Air Systems & Supplies 705-722-5747 typical placement in a COMPRESSED air system, compressor intake - Locate air compressor so thatcontaminants potentially harmful to the dryer ( ammonia)are not drawn into the air air flow - Do not block either side of the 12 inches (305 mm) on each side of cabinet for freeair flow. Standard units are designed to operate inambients from 35 to 110 F (2 to 43 C). in altitudes above 4500 feet (1370 meters) - dryer is adjusted to operate in altitudes up to 4500 feet(1370 meters). If dryer is installed in an altitude above this, and has notbeen preset at the factory for this altitude, contactmanufacturer s Service SEPARATOR OIL RECEIVER REMOVAL FILTER AFTERCOOLER AUTOMATIC dryer DRAIN TYPICAL COMPRESSED AIR SYSTEM155 and 10 )INSTRUCTIONTAGSERIAL NUMBER TAGIMPORTANT:READ PRIOR TO STARTING THIS EQUIPMENTNOTEO utdoor installation- Standard units are designed for indoorinstallation.

Keyhole slots are also provided in the cabinet as an optional mounting Base mounting - dryer may be installed on a suitable shelf or floor Piping connectionsA. Air Inlet - Connect COMPRESSED air line from air source to air inlet. WARNING Refer to Serial Number Tag for maximum working pressure. Do not exceed dryer 's Maximum Working PressureNOTEI nstall dryer in air system at highest pressure possible ( beforepressure reducing valves)NOTEI nstall dryer at coolest COMPRESSED air temperature possible.

5 Maximuminlet COMPRESSED air temperature: 120 F (49 C). If inlet air exceedsthis temperature, precool the air with an Air Outlet - Connect air outlet to downstream air If servicing the dryer without interrupting the air supply is desired, piping should include inlet and outlet valves and an air by-pass air by-pass valve, if ordered with dryer , has been shippedseparately in carton for field mounting.

Maximum inlet air pressure: refer to unit serial number tagB. Minimum inlet air pressure: 20 psig ( bar)C. Maximum inlet air temperature: 120 F (49 C)D. Maximum ambient temperature: 110 F (43 C)E. Minimum ambient temperature: 35 F (2 C) Start-up Energize dryer . Power-on light will Operating check points Check the following on a periodic basis:A. Green power-on light is Red high air temperature warning light is out. The high air temperature warning light will illuminate when dryer is energized. Light should go out approximately 15 minutes after start-up.
