Instructions
Reference Description
1 The inlet grids and ventilation fan should be installed in such way that any recirculation of
the cooling air is avoided. The maximum air velocity through the grids is 5 m/s (16.5 ft/s).
The maximum allowable pressure drop over the cooling air ducts is 30 Pa (0.12 in wc).
When 30 Pa is exceeded a ventilation fan should be installed at the outlet of the cooling
air ducts.
2 Make sure all free water is removed from the compressed air before it enters the dryer.
The water separator and drain system of the dryer are not designed to handle the water
formed in the aftercooler of the compressor.
3 Make sure that no dirt particles (e.g. coming from corrosion in the compressed air network)
can enter the dryer. These particles may be harmful to the dryer's heat exchanger and the
condensate drain.
4 It is recommended to install bypass pipes over the dryer with bypass valves in order to
isolate the dryer during service operations, without disturbing the compressed air delivery.
5 Power supply cable to be sized and installed by a qualified electrician.
6 The condensate drain pipes from the dryer to the collection point must not become
submerged in the collected condensate.
Do not allow untreated condensate to enter the draining system.
7 The refrigerant dryer should be installed on a level floor suitable for taking the weight of
the dryer.
• All pipes to be installed stress-free to the dryer. Do not use the dryer as support for
external pipes.
• Avoid installation of the dryer in corrosive atmosphere.
• The dryer is not designed for outdoor use.
•
Install a safety valve on the connection pipe between the compressor and the dryer!
