2.3 Installation instructions
1. Install the dryer where the ambient air is as clean as possible
and where the temperature of the air will never exceed or
drop below the temperature limits (see section 7). Keep
the ventilation gratings of the dryer free.
2. Connect the compressed air lines to the marked inlet and
outlet pipes of the dryer; if required, via valves and
preferably a by-pass valve. Apply a sealing medium to the
threaded connections.
3. Fit manual condensate drain valve (2-Fig. 8) onto the
condensate drain pipe.
Lay out the condensate drain hose (3-Fig. 8) via a funnel
towards a drain collector to allow visual inspection. The
hose must pitch downwards, away from the dryer and the
open end must never dip into the water of the drain collector.
If the condensate drain has been led down outside the
compressor room where the pipe may be exposed to freezing
temperatures, the pipe must be insulated.
