2.3 Information about remaining risks of the equipment

Fire:
This equipment, in accordance to EN-378-2, isn't supplied with freon drain safety valve.
In case of fire it is preferable to use fire extinguishers or extinction systems basically composed of powder or foam or carbon dioxide: it is possible to
cool the equipment thanks to nebulized water.
Avoid the massive use of water because, in case of freon gas leak, the chemical reaction can cause caustic effects, even if small.
In any case it is necessary to cool down the ambient and/or the equipment's temperature and before any intervention wait until the temperature has
been reduced.
Therefore it is preferable to insert this equipment into the Fire Prevention and Factory Safety Plan.
Arrange adequate actions capable to prevent and fight the possible risk.
Dispersion of freon gas in the ambient:
the refrigerant means is toxic only if inhaled at high concentration: it is necessary to provide an adequate ventilation in the room where the equipment
is installed.
In any case check the scheme showing the values and the risk sentences.
Excessive pressure on the compressed air side:
this equipment isn't supplied with safety devices on the compressed air side.
The safety devices on the compressed air side must be carried out by the installer.
Such devices will have to be carried out according to the applicable National Norms and to the limits mentioned in this Manual.
Ozone layer deterioration:
The adoption of HFC freon reduce to the minimum ozone layer deterioration and greenhouse effect.

3.0 INSTALLATION

3.1 Acceptance, unpacking 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. Obtaining the delivery person's signed agreement to any noted damages will
facilitate 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. Dispose the various packaging materials in compliance
with the relevant rules locally in force.
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.
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.
