3 Installation & Commissioning
Only competent personnel trained, qualified, and approved by domnick hunter should perform installation, commissioning
and service procedures.
Warning

3.1 Recommended system layout

The dryer should be installed with the correct pre-filtration and condensate management equipment to meet both the specification and local
environmental requirements.
Referring to diagram A4 in Annex A, the following equipment is recommended to meet these requirements:
Ref Description
1 Compressor
2 Wet air receiver
3 Bypass Line
4 Isolation Valves
5 AA Filter
The use of a bypass line will allow wet untreated air into the system. It should therefore only be used in extreme
circumstances.

3.2 Locating the equipment

Identify a suitable location for the equipment taking into consideration the minimum space requirements for maintenance and lifting equipment.
When considering the final location of the equipment take into account the noise generated when in use.
The dryer can be free standing or secured to the floor via the fastener points provided in the base..

3.3 Mechanical Installation

Once the dryer has been located into position install the piping and filtration for connection to the inlet and outlet manifold. AA grade filter is
required at the dryer inlet and a AR grade filter at the outlet as shown in diagram A5 of Annex A.
Ensure that each filter condensate drain is suitably piped away and any effluent is disposed of in accordance with local regulations.
Ref Description
1 AA grade filter
2 AR grade filter
3 By-pass line
The Dewpoint Dependent Switching (DDS) system requires a sampling point to be inserted into the piping between the AR grade outlet filter
and the isolation valve as shown in diagram A5. This sampling point should be linked to the 4mm push in connector of the DDS system using
P.T.F.E tubing.
It is important to ensure that all piping materials are suitable for the application, clean and debris free. The diameter of the pipes must be
sufficient to allow unrestricted inlet air supply to the equipment and outlet gas / air supply to the application.
When routing the pipes ensure that they are adequately supported to prevent damage and leaks in the system.
All components used within the system must be rated to at least the maximum operating pressure of the equipment. It is recommended that the
system be protected with suitably rated pressure relief valves.
A by-pass line may be installed into the system to provide a constant air supply during maintenance.
The by-pass line will allow untreated air to pass to the application and should only be used when the dryer has been shut
down.
