f) Do not obstruct the dryer air grilles.
g) Avoid recirculation of hot condenser air back into the condenser air inlet.
h) If the system is prone to instantaneous pressure surges which exceed the dryer's
rated capacity, mount a suitably sized receiver near the overpressure source. For
more precise information, contact the manufacturer or distributor.
i) It is necessary to install a pre--- filter (max. 3 micron) on the dryer intake to pre-
vent rust, scale or other pollutants from entering the system and clogging the
condensate drain and heat exchangers, thereby causing severe pressure drops.
This filter must be close to the dryer inlet.
j) Always install a bypass line with shut---off valves (supplied as option) to permit
maintenance or calibration without interrupting the compressed air flow to the
user.
k) Correctly connect the dryer to the air inlet and outlet connections. If the com-
pressed air network is prone to vibrations, use hoses to make the connections.
If the mains is subject to high levels of pulsation, ensure that the connection is
equipped with pulsation dampers.
l) Do not connect condensate drains common to other pressurised drain lines in a
closed circuit. Make sure the outflow from the condensate drains is unimpeded.
Connect the condensate piping in such a way to ensure that sound levels are kept
to a minimum during drainage.
Ensure that all condensate is disposed of in a responsible manner, in accordance
with local norms concerning environmental protection.
m) The ambient air around the dryer and compressor must not contain solid or gas-
eous contaminants. All compressed and condensed gases can generate acids or
chemical products which may damage the compressor or components inside the
dryer.
Take particular care with sulphur, ammonia, chlorine and installations in marine
environments. For further advice or assistance consult the manufacturer.

2.1 Electrical connection (see Fig. 4 / Fig. 9)
Use a cable that complies with regulations in force in the country of installation (con-
nected to terminals "L and N
junction box, with minimum wire sizes: (see machine electrical schematic in Fig. 9).
Install an overcurrent and earth leakage circuit breaker upstream from the
plant (IDn = 0.3A) with a 0.12 inch (3 mm) gap between contacts when open (refer
also to local laws).
2.2 Condensate drain connection
The dryer is supplied either with a timed drain or an electronic level sensing drain.
Refer to the separate manual supplied with the dryer for specific details concerning
the condensate drain.
3 Start---up and operation
3.1

Preliminary checks

Before starting up the dryer, make sure that:
a) the air inlet valves are closed and there is no air flow through the dryer.
b) The mains power supply is commensurate with the dryer voltage.
c) The dryer is installed in compliance with the installation instructions given in
Chapter 2.
