7.
Connect the compressed air to be treated to
the drier inlet (lower port) with pipes which do
not place stresses and strains on the appliance.
8.
The compressed air to be treated must be taken
from the upper part of the tanks to reduce the
risk of transporting liquid phase water or
particles. This will extend the service life of the
appliance.
9.
Connect the treated compressed air to the
exhaust side of the drier with pipes which do not
place stresses and strains on the appliance.
10. If the compressed air production system is not
fitted with a safety device (valve or pressure
switch) you must fit a safety valve to each tank
They must act directly on the tank with no
intermediate position and possess a discharge
capacity higher than the quantity of air inlet to
the tanks, calibrated and sealed at the safety
pressure of your network which must always be
under 20 bars.
11. Check all connections for leaks.
12. Connect the drier and filter purge lines to your
condensate treatment system (water/oil
separation). Unless otherwise stipulated by
applicable legislation, do not drain wastes to
sewers without prior treatment.
* see ISO standard 8573-1
For air dryer inlet and outlet connexion's tightening, be sure not to use too much screwing tight power
which would damage the evaporator coil piping of the thermal mass.

Electric connection
Risk of electric shock: the circuit must be wired by a qualified electrician in compliance with applicable
legislation and the specifications of the appliances to be connected.
Check that voltage and frequency comply with the values shown on the manufacturer's plate on the
machine and that they are within the tolerances shown on the electrical circuit diagram.
Check that the electrical installation complies with laws and regulations current in the place where the drier
will be installed. Only use the electric cable provided with the machine or equivalent.
At the entry of the electric cable, a safety device must be installed for:
•
Protection from short-circuits and voltage surges;
•
Protection from the indirect contacts on the machine (short-circuit between phase and equipotential
safety circuit) by automatically power supply cut-off as stipulated in IEC standard 364 - HD384 IEC 64-8;
•
Protection from the failure of one phase in a three-phase electric installation.
For safety circuit dimensions, refer to the data shown in the electric diagram (maximum current, peak current,
cable cross-section).
