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 (40 inches, 1 m) 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. Ensure there is no spreaded glycol and clean carefully if any.
5. 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.

4.0 START-UP

•
Make sure that intake and outtake valves are closed, switch on the devices (1S1).
•
TO START THE DRYER IT IS NECESSARY TO PRESS AND HOLD THE ON/OFF BUTTON FOR AT LEAST FOR 3 SECONDS
•
THERE IS A DELAY BEFORE THE DRYER WILL START AFTER THE DRYER IS TURNED ON, IN ORDER TO WARM UP COMPRESSOR OIL.
•
IF THE UNIT FAILS TO START MAKE SURE THAT PHASES ARE CONNECTED CORRECTLY.
•
Allow some minutes for the dryer to run at full speed, i.e. until the displayed value on the temperature display is within the field of good operation
(about 3° C).
•
Now open the outlet air valve and then open gradually the intake air valve. In this way, the plant is gradually pressurized.
•
If the plant is overloaded over the max. use limits (see technical data), the dryer's performance will be remarkably lower but safety will not be in
danger.

5.0 MAINTENANCE

5.1 Weekly

Check visually if the condensate is properly drained.

5.2 Monthly

Clean prefilter to remove any possible dirt on the inner filtering element.
Perform the following after stopping the compressed air flow by closing the intake and outtake valves.

5.3 After 6 months

Isolate the machine before performing the following.
According to the room temperature quality and when summertime begins, clean the condenser with a low pressure air jet and clean the fins of the unit to
remove possible scales or deposits the might decrease its performance.
Check that the compressor power consumption values fall within the range detailed on the machine plate (see compressor product label).
