• The electrical equipment of the dehumidifier must be checked re-
gularly. Repair loose connections and damaged cables immedia-
tely.
• The control cabinet must be kept locked at all times. Access is
only allowed to authorised personnel with a key or a tool.
• If work on live parts is necessary, a second person must be in
attendance to turn off the main switch in case of emergency.
Service, maintenance and troubleshooting
• The prescribed adjustment, maintenance and inspection work must
be carried out at the specified intervals.
• Operating personnel must be informed before commencement of
the maintenance and service work.
• All plant parts upstream and downstream of the dehumidfier and
operating media such as steam must be secured against unintenti-
onal switching on.
• Switch off the dehumidifier and secure it against being switched on
again for all service, inspection and repair work.
• Attach a warning sign to prevent switching on again.
• Larger subassemblies should be attached and carefully secured to
lifting devices when exchanging them.
• Check loosened screwed connections for tightness.
• Check the function of safety devices after completion of the mainte-
nance work.
Structural modifications to the dehumidifier
• The dehumidifier may not be modified or converted, nor may additio-
nal parts be attached without the manufacturer’s permission. This
also applies to welding on load-bearing parts.
• All conversion work requires the confirmation of Trotec GmbH.
• Machine parts that are not in perfect working order must be repla-
ced immediately.
• Only original spare and wearing parts are to be used.
• In the case of parts procured from third parties, it cannot be gua-
ranteed that these have been designed and manufactured to meet
the load and safety requirements.
Cleaning and disposal of the dehumidifier
• Handle and dispose of used substances and materials with care, in
particular
- when working on lubrication systems and devices
- when cleaning with solvents.
02. Transport and installation
Transport
The dehumidifier may only be tilted very slightly during transport. On
arrival at the building site, the appliance must be checked for com-
pleteness and correlation to the delivery note as well as for possible
transport damage.
Handling with a fork lift truck
Make sure that the forks are long enough to take up the entire length
of the appliance, as otherwise the housing of the appliance could be
damaged.
Handling with a crane
The appliance should be lifted by the lifting eyes. The tube ends or the
throttle flaps may not be used as lifting points.
Installation of the dehumidifier
The following points are to be considered when installing the dehu-
midifier:
• The appliance must not be exposed directly to the weather.
• Ensure that the lifting device can take the weight of the appliance.
• Ensure that the intended installation surface is even and can take
the operating weight of the dehumidifier. A foundation is not neces-
sary for the dehumidifier.
• A space of at least 800 mm must be kept free in front of the ope-
rating side and the inspection panels of the dehumidifier for possib-
le maintenance work. Furthermore a space of at least the same
width as the appliance must be kept free in the rotor area for ex-
change.
• The dehumidifier is a compact unit. The customer has to make the
air, (steam) and electrical connections.
• Refer to the technical data sheet for the dimensions and weight of
the dehumidifier.
• The connecting cables are fed through the cable glands into the
switchbox and connected to the appropriate terminals.
• The electrical connection must consist of L1, L2, L3, N and protecti-
ve earth. Refer to the circuit diagram in the technical appendix of
this operating manual for the connections. Local regulations must
thereby be observed.
• The dehumidifier has been designed such that both the air ducts
and the electrical connections can be installed simply.
• The following types of installation are possible:
A. In the room to be dehumidified: The appliance operates in air circulati-
on mode; the regeneration air outlet is to be fed to the outside.
B. Outside the room to be dehumidified: The appliance can be operated
in air circulation or flow-through mode. The dry air must in this case be
connected to the room to be dehumidified..
In both cases it is important to ensure that the humid air outlet is installed
as far away from the process air inlet as possible.
The piping system must naturally be designed to cope with the
available static pressure of the fans. Adjustable throttle flaps at the
process and regeneration air outlets allow for optimum operation.
Throttled process air results in lower humidity of the dry air. Thrott-
ling the regeneration air is useful in the case of lower moisture levels.
