f) Avoid recirculation of hot condenser air back into the condenser air inlet.
g) 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.
h) Installing a by---pass line with shut---off valves (supplied as option) is suggested
to permit maintenance or calibration without interrupting the compressed air
flow to the user.
Pay attention when you by---pass the aftercooler section, as this will cause hot air
to flow through the compressed air network.
i) 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.
j) 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.
k) 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.
2.2 Electrical connection (see Fig. 5 / Fig. 10)
The dryer is supplied with a 3 x AWG16 power cable complete with plug.
Install an overcurrent and earth leakage circuit breaker upstream from the
plant (IDn = 0.03A) with a 0.12 inch (3 mm) gap between contacts when open (refer
also to local laws).

Condensate drain

The dryer is supplied either with a float drain (see Fig. 9), a timed drain or an elec-
tronic level sensing drain.
For timed and electronic drains: refer to 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.
3.2

Starting the dryer

a) Use the switch to start the dryer.
b) Always start up the dryer before activating the air compressor.
c) Wait about 5 minutes until the dryer is running at the correct operating tempera-
tures and pressures.
d) Slowly open the air inlet valve to pressurise the dryer.
e) Slowly open the air outlet valve. The dryer is now operating (drying).
f) Always leave the dryer running while the air compressor is operating.
g)
After stopping the dryer wait at least 3 minutes before starting it again.
3.3

Stopping the dryer

a) Use the switch to stop the dryer.
