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 the

limits (see section 7). Keep the ventilation gratings of the

dryer free.

If necessary, take action to avoid external influences (wind,

draughts, etc.) through the ventilation gratings of the dryer,

as they may disturb the cooling air flow.

2. Connect the compressed air lines to the marked inlet and

outlet pipes of the dryer (Figs. 6 and 7). Provide an air

inlet valve and outlet valve. If a by-pass pipe and valve are

installed, the dryer can be serviced while by-passing the

dryer.

3. Fit manual condensate drain valve (5-Fig. 7).

Lay out the condensate drain hoses via a funnel towards a

drain collector to allow visual inspection. The hoses must

slope downwards. For draining of pure condensate, install

an oil/water separator; consult Atlas Copco.

If the condensate drain has been led down outside the

compressor room where it may be exposed to freezing

temperatures, it must be insulated.

4. A sticker dealing in short with the operating instructions

and explaining the pictographs is delivered with the

literature set. Affix the sticker next to the control panel.

Make yourself familiar with the instructions and pictographs

explained.

5. Fit the electric plug to the voltage supply cable. Plug in the

dryer.
