HDK-CNG_EN_03_2016
Installation
All work at the pipelines and on the electrical components must be carried
out by authorised and suitably qualified technical personnel.
As soon as the dryer has been set up at its installation location, you can install
the compressed air inlet and outlet lines and make the electrical connection.
Requirements for installation
For a correct installation of the the dryer following preconditions must be met on
the part of the owner.
Connections and lines for the inlet and outlet as well as disposal of the natural
gas must be in place.
The operator must install a natural gas inlet valve, an outlet valve and a
recuperation valve, thereby enabling the dryer to be installed and maintained in
a depressurised condition.
All pipes, couplings, and connections must have the correct diameter and
match the operating pressure.
Connect the outlets from the regeneration gas safety valves to the line used to
evacuate escaping gas.
The disposal line on the regeneration gas safety valves must not include any
shutdown valves.
Hazard caused by exceeding the limit values!
The following safety devices must be installed.
One safety device to prevent operating pressure from exceeding its
maximum permitted limit, and fluid from exceeding its maximum
permitted temperature
One safety device to monitor hazardous gas concentrations and to
protect against escaping natural gas.
The data required to meet these preconditions are contained in the technical
documentation attached in the annex.
Attention!
If the above preconditions are not complied with, a safe operation of the
dryer cannot be assured. Also, the functionality of the dryer may be
detrimentally affected.
Hazard caused by unearthed/ungrounded dryer!
The electrical conductivity of the dryer in the on-site potential
compensation system must be assured during installation. Assure the
presence of appropriate connection points at the installation location.
