Chapter 5: Startup, Shutdown & Operation

5-1 Pre-Startup Checks

;Check the process and return hoses for tight connections.

;Check that all companion equipment, such as the drying hopper, loading system and aftercooler are ready for operation.

;Check the dryer electrical connections.

Note: Clean the rust-preventive oil from inside the drying hopper. Failure to clean the hopper will cause fouling of the desiccant in the dryer, and will void the warranty.

5-2 Startup

Close the slidegate at the bottom of the drying hopper.

1.Fill the drying hopper with material.

2.Turn on (energize) the disconnect switch in your power drop, then turn on the one on the dryer.

3.Flip the on/off switch to "ON."

4.Press the stop/start button.The blowers should start, and the proper control panel indicators should light.

5.Make sure both blowers are turning the right direction. Verify rotation direction is correct. If one or both blowers do not start:

•Check to see if an overload on the blower motor starter has tripped. If so, set it properly and reset. Check the blower fuses, too.

•If one of the optional Valve Position Error lights is lit, the blowers will not start. Make sure the valve arm has tripped the proper limit switch. If the electric actuator is not fully extended or retracted, check the line fuse (8FU) near the actuator's 24 VDC power supply.

The valve actuator has built-in limit switches to shut off its motor.

It must fully extend and retract to prevent the motor from burning out.

•If a blower failure light is lit after the blower has run for a few seconds and shut down, the blower pressure switch will need to be adjusted until the failure light goes out.

The pressure switches at the rear of the dryer were adjusted during factory-testing. Pressure changes in the drying system as installed may make some adjustment to these necessary during initial startup.
