Safety instructions
The present installation manual is only valid for Wolf heat wheel heat exchanger
RWT in split version. This manual has to be read by the personnel instructed with the
particular operations before installation, start up and maintenance.
The requirements stated in this manual have to be met.
Installation work is exclusively permitted to be done by skilled and specialised staff.
The installation and maintenance manual has to be kept accessible as a part of the
unit for future purposes.
Failure to comply with this manual will lead to expiration of the warranty claim to Wolf.
The following symbols and signs are used in this installation manual. Theses
important instructions concern personal security and the technical safety in
operation.
"Security advice" marks the instructions that have to be met exactly to prevent
endangerment and injury of persons and to avoid damages at the unit.
Danger aroused by voltage on electrical parts!
Warning: Before you take off the cover, switch-off engage switch. Never touch
any electrical parts and connections when engage switch is switched on!
An electric shock with health risk or death result might be the danger.
There is also voltage at the connecting terminal when the operating switch is
switched on.
„Advice" marks technical instructions, that have to be kept in mind in order to
NB
avoid damages and malfunction at the unit.
If there is any advice in addition to the installation manual sticked to the unit as a
label, they have to be adhered to in the same way.
For installation, start up and operation of the unit, a sufficiently qualified and briefed
staff has to be employed.
Operations at the electrical installation are only allowed to be carried out by skilled
electricians.
For electrical installations the regulations of the VDE and the public utility (EVU) are
decisive.
The unit is only allowed to be operated within the range of performance set in the
technical documentations of Wolf.
The conventional use of the unit includes the exclusive application for ventilation
purposes. Only air is allowed to be transported.
This must not contain harmful, combustible, explosive, aggressive, corrosion- pro-
motion or in any other way dangerous parts, as otherwise these substances could be
spread in the pipe system of the building and the people, animals and plants living in
the building could be affected in their health or even be killed.
Safety and surveillance installations are not allowed to be removed, bypassed or in
any other way be put out of operation.
The unit is only permitted to be operated in technical sound state. Damages that
affect or might affect the function of the unit have to be rectified immediately by an
expert.
Defective parts and unit components are only allowed to be replaced by original
WOLF spare parts.
The assembly of the heat wheel heat exchanger casing necessarily has to be effec-
NB
ted before the actual unit assembly.
Reason: all-round free accessibility necessary for the assembly of the heat wheel
heat exchanger (the use of a installation gantry is recommended).
For the assembly of the heat wheel heat exchanger a flat, horizontal and sufficiently
stable ground is necessary.
