Installation Procedure 

 

Only Qualified personnel should make electrical and mechanical connections.  
 

Foundation:  

Dryer should be mounted on a suitably structured flat and level floor 

or base that is free from vibration. Special care must be used when 

lifting the dryer to prevent tip-over 

 
Mounting:

 

Bolt dryer to the foundation using the boltholes provided in the frame. 

 

Piping:  

Connect the inlet of the dryer to the moist gas from the 
compressor/receiver/inlet filter. Install the inlet piping and the inlet 

shutoff valve. Install the Outlet piping and the outlet shutoff valve (a 

union with a valve by-pass can be installed at the inlet and outlet 
valves to accommodate isolation of the dryer for maintenance). 

Compressed air piping has to be at least the same size as that of the inlet 
and outlet connections of the dryer. Larger pipe sizes can be used with 

reducers.  

 

Back Pressure regulators:  

Install backpressure regulator to prevent any possibility of fluidization of the 
desiccant bed. When there is a sudden increase in the demand for 

compressed air downstream of the dryer, a huge pressure drop develops and 
can affect the performance of the life of the dryer and the drying material 

(desiccant).  

 

Desiccant:  

Make sure that the dryer towers are filled with desiccant. Larger dryers may 
have desiccant shipped separately 

 in which case, the media has to be filled 

into the pressure vessels from the desiccant fill ports. Care must be taken 
when filling the media and it must be done gradually to prevent powdering.  

 

Muffler:  

In the event that mufflers have been shipped loose, they must be installed 

and secured 

 

By-pass: 

If the dryer is not supplied with optional block and by-pass valve system it is 

highly  recommended  that  a  block  and  by-pass  valve  system  be  installed 
around the dryer and filters. This block and by-pass valve system will permit 

the  dryer  and  filters  to  be  removed  from  the  compressed  air  system  for 

servicing without shutting down the entire compressed air system. Ensure that 
the bypass valves are rated for more than 250 Deg. F.
