Preparation For Commissioning - Parker Zander WVM Series Operating Manual


Operate the dryer only within the permitted limits. Operation of the dryer
under conditions for which it is not designed may lead to malfunctions.

On no account should the factory settings of the control programme and the
frequency converter be altered without consulting the manufacturer.

The higher the capacity of the dryer, the more noise it produces during
operation. The operator must therefore provide suitable protective equipment
(e.g. earmuffs).

Depending on the size of the dryer, the compressed air network and the
respective legal requirements in your country, it may be necessary to perform
initialisation according to the directive for pressure equipment.

Check the dryer for visible damage and faults at regular intervals.
Immediately report changes, also those regarding operational behaviour, to
the institution or person in charge.

In the event of an emergency or if safety-relevant malfunctions are observed,
immediately switch off the dryer. The dryer may only be restarted after the
malfunction has been eliminated.

Preparation for commissioning

For the commissioning of the dryer, follow the instructions as set out below.
Pressurisation of unit
► Check the stop valves at the vessel pressure gauges to ensure that they
are opened (see page 17).
► Check the valves at the inlet and outlet for the compressed air (provided by
operator) and ensure that they are closed (see also example of installation
on page 33).
► Ensure that the compressed air system in front of the dryer is pressurised.
Adjust pressure, if necessary. Switch on compressor.
Slowly open compressed air inlet valve!
Avoid abrupt pressure increase! Rapid pressurisation may lead to serious
damage to the dryer! Therefore, open compressed air inlet valve slowly
and with caution!
► Slowly open compressed air inlet
valve leading to the dryer.
► Monitor the pressure increase at the
vessel pressure gauge (see page 17):
In one of the vessels, the pressure
must be increased until it reaches the
operating pressure.
