INSTALLATION CHECK LIST:
1. Verify and record voltage
2. Verify drain is not reduced or obstructed.
3.Drain tubing size and approximate length of run
4. Duct work should not be added to dryer unless proper ventilation/booster fan is added. Dryer ducted? Yes___ No____
5. CFM/HP of compressors supplying air dryer
6. Any external control wiring to the dryer? Remote start/stop auto restart etc. If so, please note:

THE FOLLOWING INSTRUCTIONS SHOULD ONLY BE COMPLETED AFTER INSTALLATION AND INITIAL INSPECTION CHECK LIST.
1. Apply power but do not start the dryer for 4 hours allowing the crankcase heater to heat up any liquid that has migrated to the compressor.

3. Allow 10 minutes for pre cooling then start flowing compressed air to the dryer
4. Confirm drain operation by pressing the TEST button

5. Record the following:

Air Inlet Temperature  

 

Ambient Temperature

 

Refrigerant Suction Presssure

 

Refrigerant Discharge Pressure

 

Dewpoint on Temp Readout

 

Compressed Air Pressure

 

 

6. Confirm fan is cycling on/off as designed and that the return line to the compressor is cool. If possible record refrigerant compressor inlet temperature 

7. If Air dryer is water cooled be sure to set the water regulating valve to 150 PSI discharge pressure. Then record the following
