Installation
Only authorized and qualifi ed specialist personnel may carry out work on pipes
and electrical systems.
The electropneumatic switch cabinet in particular must be opened and ser-
viced by an instructed trained electrician only
As soon as the dryer has been set up at its installation location, you can install the com-
pressed air infeed and outlet lines and make the electrical connections.
Requirements for installation
Risk of damage resulting from exceeding the limit values!
A safety device protecting against exceedance of the maximum permissible
operating gauge pressure must be present.
The safety device must be installed so that the dryer is reliably protected from
exceeding the maximum permitted operating pressure even when the tempera-
ture of the compressed gas increases.
Warning!
Safe dryer operation cannot be ensured if the requirements described here are
not met. This can also degrade the dryer's function.
For proper installation, the operator must provide the following:
◊ Connections and lines must be provided for compressed air intake and exit.
◊ The operator must install shut-off valves for compressed air and supply media at the
intakes and exits.
◊ All pipelines, couplings and connections must have the correct diameter and be matched to
the operating pressure.
If the regenerated gas is supplied to and led away from the dryer by ducts or pipelines in-
stalled by the operator, the following instructions must be adhered to:
Avoid any loss of pressure!
A pressure loss in the air inlet and outlet pipelines >20 mbar may signifi cantly
affect the dryer's functionality. The consequences may include the following:
—
Failure to reach the pressure dewpoint
—
The dessicant will become unusable well before expiry of its normal
useful life
It is therefore vital to observe the following points:
—
Do not allow the maximum pressure loss in the air inlet and outlet pipe-
lines to exceed 20 mbar (e.g. maximum 10 m pipline with three bends)!
