START-UP

Follow the procedure below to start your dryer. Failure to follow the prescribed start-up  

procedure will invalidate the warranty. If problems arise during start-up, call your dis-  

tributor. 

1. Turn the dryer ON/OFF switch to OFF. 

2. Turn on the main electrical power to the dryer.     

3. Don’t turn the power switch to ON directly! Refer to the below. 

To start dryer :

1.  Turn the power switch to ON. The refrigerant compressor will turn on. 

2.  Confirm that condensate is discharging from the drain valve. 

3.  Check drain valve timing. See Electronic Drain Valve section for drain valve adjust- 

ment procedure. 

4.  Check that the main electrical supply voltage matches the voltage specified on the 

dryer data plate. 

5.  Check proper connection and support of compressed air lines to the dryer; check 

bypass valve system, if installed. 

6.  Ensure adequate ventilation for air-cooled dryers. 

7.  Confirm that the inlet air temperature, pressure and airflow to the to the dryer meet the 

specified requirements (see Table 4 & 5) 

8.  confirm that the condensate lines from the drain valve discharge into a collection tank 

or an environmentally-approved disposal system. 

9.  If the refrigerant Suction Pressure Gauge is out of range, refer to the Field Service 

Guide for information or contact your local distributor. 

The dryer is designed to run continuously. Let the dryer run even when the demand for   

compressed air is interrupted; the dryer will not freeze up. 

IMPORTANT 

  Energize dryer for 4 hours before refrigeration compressor is started! Never use the 

disconnect switch to shutdown the dryer for an extended period of time (except for 

repair). Failure to follow these instructions may result in a non-warrantable compressor 

failure.
