2.1 ACCEPTANCE  AND HANDLING 

Upon receiving your OMI air dryer, please inspect the unit closely. If rough handling is detected, please note it on your delivery receipt, 
especially if the dryer will not be uncrated immediately. Then obtain the freight carrier's signed agreement to any noted damages:  this 
is a precondition for any insurance claims by the customer. 

It is mandatory to keep the dryer always in vertical position, as indicated by the symbols present on the packaging. For handling, use 
devices having sufficient capacity for the weight of the machine. 

Remove the packaging after having positioned the dryer in the installation site. For unpacking, refer to section 2.3. 

Under no circumstances should any person attempt to lift heavy objects without proper lifting equipment (i.e., crane, hoist, slings or fork 
truck). Lifting any unit without proper lifting equipment, may cause serious injury. Use fork lift channels where provided. 

2.2 STORAGE AND INSTALLATION LOCATION 

If not in use, the dryer can be stored in its packaging in a dust free and protected site between 32°F (0°C) and 120 °F (50 °C), and a 
specific humidity not exceeding 90 %. Should the stocking time exceed 12 months, please contact your local OMI authorized distributor.

Ambient temperature complying with the nominal data of the dryer. 

 

The dryer should be located in a clean area, without forced air draft that can affect the fan control system. 

 

Make sure to leave sufficient clearance (20 inches, 500 mm) around the dryer in order to allow an adequate cooling 
of the machine and for maintenance and/or control operations. 

 

The incoming air must be free from smoke or flammable vapours which could lead to explosion or fire risks.
