Section 2.0 - Getting Started 

 

 

Before unpacking/uncrating your new dryer, inspect the carton/crate 
for damage.  Note any damage on the freight bill.  File notice of 
concealed damage if: 
 

(a)

 

there are any dents in the cabinets 

(b)

 

the air and drain pipes are not straight 

(c)

 

there is any sign of oil on the skid or floor 

(d)

 

the refrigerant gauges show NO pressure 

 

File these claims with the carrier immediately! 

 
Otherwise, proceed with unpacking/uncrating the unit. 
 
 
Environmental & Location Considerations 
 

Following these guidelines will help insure that your new dryer will provide safe and 
reliable service. 

 

ƒ

 

Unless supplied for special conditions, air cooled dryers must be located in an 

area with an ambient temperature between 50…95ºF (10…35ºC) and free 
from explosive and corrosive fumes.  Three (3) feet (92cm) of space must 

be allowed between all open grills, walls, or other objects. 

 

ƒ

 

Where ambient temperatures may periodically fall into the 35…50

ºF 

(1.6…10ºC) range, dryers are equipped with a low ambient fan control.

 

 

ƒ

 

Dryers for below freezing (31º, -5ºC) 

ambient temperatures

 are available with an 

optional additional refrigeration condenser bypass valve.

 

 

 

 

           

If the dryer is installed in a confined area, an exhaust system must be      

provided to eliminate recirculation of hot atmospheric air. 

 

 

ƒ

 

High ambient temperatures affect the outlet dew point of the dryer.  For 
every 10º of ambient temperature over 95ºF (35ºC) a decrease of 9% of 

dryer performance is encountered with air cooled dryers.  The unit must not 
operate in an ambient of over 115ºF (46ºC).  If ambient temperature 

conditions are over 95ºF (35º), water cooled dryers are recommended.
