2.4 CONNECTION TO THE COMPRESSED AIR SYSTEM
Operations to be performed by qualified personnel. Never perform maintenance with unit under pressure.
The user is responsible to ensure that the dryer will never be operated with pressure exceeding the
nominal values. Eventual over-pressure could be dangerous both for the operator and the machine.
The temperature and the amount of air entering the dryer must comply with the limits reported on the data plate.
The cross section of the connecting piping, which must be free from dust, rust, chips and other impurities, must be
consistent with the flow-rate of the dryer. For maintenance operations a by-pass is system is recommended
Particular measures have been taken in order to limit the vibration, which could occur during the operation. Therefore we
recommend using connecting pipes that insulate the dryer from possible vibrations originating from the line (flexible
hoses, vibration damping fittings, etc.).
2.5 CONNECTION TO POWER SUPPLY
Qualified personnel should carry out the connection to the power supply and the safety systems must comply with
local regulations. Before connecting the unit to the electric power, verify that the voltage and the frequency
available on the mains correspond to the data reported on the data plate of the dryer. In terms of voltage, a ±5%
tolerance is allowed. The dryer comes with a main connecting cable already installed and ending with a plug.
The main socket must be provided with a
magneto-thermal differential breaker
(I
n=0.03A),
adjusted on the basis of the consumption of the dryer (see the nominal values on the data plate of the dryer).
The cross section of the power supply cables must comply with the consumption of the dryer, while maintaining
ambient temperature, the conditions of the main installation, the length of the cables,
and the requirements enforced by the local Power Provider. Ensure the dryer is properly grounded.
Do not use adapters on the main socket. If necessary, have the plug replaced by qualified personnel.
2.6 CONDENSATE DRAIN
The condensate is discharged at the same pressure of the air entering the dryer.
Never point the condensate drain outlet towards a person.
The dryer comes already fitted with tubing in flexible plastic (6mm in diameter and 1500 long) for the connection
to the collection plant.
Condensate drainage occurs by means of two separate circuits. The first removes the condensate through a 5-
micron filter at the outlet of the aftercooler and the drainage is by an automatic system. The other circuit collects
the condensate from the demister separator filters it and then expels it by means of a solenoid valve controlled by
the Air Dry Controller.
•
Connect and properly fasten the condensate drain to a collecting container.
•
The drain cannot be connected to pressurised systems.
•
The condensate collected in the dryer contains oil particles released in the air by the compressor.
•
Dispose of the condensate in compliance with the local regulations.
•
We suggest installing a water-oil separator to remove all the condensate coming from compressors, dryers,
tanks, etc.
3.1 PRELIMINARY OPERATION
Verify that the operating parameters match the nominal values reported on the data plate of the dryer (voltage,
frequency, air pressure, air temperature, ambient temperature, etc.).
Before delivery, each dryer is submitted to accurate tests simulating real operating conditions. Nevertheless, the unit
could be damaged during transportation. We suggest checking the integrity of the dryer upon arrival and to keep it under
control during the first hours of operation.
Qualified personnel must perform the start-up.
Never operate the dryer if the panels are not in place.
