2.4 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.
The pipes to be connected to the dryer does not weigh on the device.
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.
It is necessary for the user to install a protective device (a safety accessory) to protect the equipment under
pressure from the risk of exceeding the maximum allowable pressure (PS); it is necessary to install a protective
device to protect the equipment at high temperature from the risk of exceeding the maximum allowable
temperature.

3.1 BEFORE START UP

Before starting the machine, make sure that all operating parameters correspond to the nominal data.
The dryer is supplied already tested and preset for normal operation, and it doesn't require any calibration.
Nevertheless, it's necessary to check the operating performances during the first working hours.

3.2 START UP

The operations specified below must be performed after the first start up and at each start up after a prolonged
inactive period of time due to maintenance operations, or any other reason.
1. Make sure that all instructions contained in chapters INSTALLATION SITE and INSTALLATION have
been observed.
2. Ensure dryer by-pass is open and air inlet/outlet valves closed. (if existing).
3. Activate power supply and press the ON/OFF switch on the control panel for at least 1 second.
4. Wait 5 to 10 minutes until machine has achieved its standard operating parameters.
5. Slowly open the air outlet valve and successively open the air inlet valve.
6. If existent, close the air by-pass valve.
7. Check if the condensate drain is working properly.
8. Check if all connecting pipes are properly tightened and fixed.
Before disconnecting the dryer from electrical power supply, use ON/OFF switch to stop the dryer.
Otherwise wait 10 minutes before switching the dryer on again, in order to allow freon pressure to
rebalance.
