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.

3.2 Installation site

While preparing a proper site for the installation of the dryer, please take into account the following requirements
The machine must be protected from atmospheric agents and not directly exposed to sun light.
A seating base flat and capable to hold the weight of the machine.
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.
3.3 Installation
Before attempting any installation operation, make sure that
No parts of the air system are under pressure.
No parts of the system are electrically powered.
Tubing to be connected to the dryer are free of impurities.
All interconnecting piping has been tightened.
After having verified the points listed above, you can proceed to the installation of the machine.
1. Connect the dryer to the compressed air lines. If not already existing, we suggest to install a by-pass allowing to
isolate the machine from the plant, thus to facilitate eventual maintenance operations.
2. Perform the electrical connection in accordance with any local laws and regulations after reviewing the dryer
electrical specifications and wiring diagram.
3. Check the condensate drainage assembly, and connect the drain flexible hose to the draining line, keeping in
mind that the condensate separated by the dryer may contain oil, therefore, in order to dispose of it in
compliance with the local rules in force, we suggest installing a water-oil separator having adequate
capacity.
4. Power the dryer after having checked that the nominal voltage and line frequency are constant and matching the
nominal values of the machine. The user must provide the installation with an adequate line protection
and a ground terminal complying with the electrical rules locally in force.
In order to optimise the use of the dryer, we suggest to place it in such a way that all the control instruments of the
machine will result easily visible.
A suitably sized prefilter must be installed before the dryer. Failure to install and maintain a proper prefilter will
void the dryer warranty. The rating for this filter must be at least 10 micron.
