Information from the producer
AeroMaster FP air-handling units are produced
according to valid czech and european technical
regulations and technical standards. Units can only be
installed and used according to this documentation.
Installation and service instructions must be accessible
to service attendance and therefore it is useful to place
it close to the unit.
Application and working conditions
AeroMaster FP air-handling units are intended for com-
fortable air-handling and air-conditioning of smaller
rooms. They are manufactured in two dimensional ran-
ges, FP 2.7 and FP 4.0, for air ow ranges from
500 m3/h to 4,500 m3/h at air pressure deference of the
fan of up to 1200 Pa. AeroMaster FP air-handling units
are designed to transport air without solid, brous, stic-
ky, aggressive, respectively explosive impurities. The
transported air must be free of corrosive chemicals or
chemicals aggressive to zinc and steel, respectively
aluminium. When designing the air-handling assembly,
it is necessary to take into account the temperature and
humidity of the inlet and outlet air in relation to the am-
bient temperature and humidity. It is especially necessa-
ry to analyze the relation of the unit's casing classica-
tion pursuant to EN 1886 and the risk of condensation
respectively, ice build-up. AeroMaster FP air-handling
units can be used in normal rooms (IEC 60364-5-51,
resp. ČSN 332000-5-51 ed.2, ČSN 332000-1 ed.2) and
in rooms with extended ambient temperature range ran-
ging from -30 °C to +40 °C without additional measures.
Degree of protection - IP 40. The unit's accessories
(M&C) are not included - they must be assessed sepa-
rately.
Construction of air handling unit
Unit construction is sectional, modular. Casing is com-
posed of panels and connecting bars between them.
Panels are attached to connecting bars and by thread-
ed joints between each other. For cases of regular
maintenance or inside checks (change of ltration
inserts, cleaning etc.), the sections are equipped with
service panels which have the same construction as
stationary panels but they are equipped with handles
and xed by turning thrust latches.
All panels have sandwich construction with total width
of lateral insulation of 40 mm, upper and bottom of 25
mm with quality anticorrosive treatment. Panels are pro-
vided with PE seal sticked to panel surfaces of contact.
Complete air handling unit Viking FP is composed of
sections. The sections are (mechanically) separate
while the lateral panel of the section is compact (panel
without bars). The section is functionally dened by a
casette.
Unit labelling
Every section (except the frame) is provided with type
(production) label of section, with following data:
producer name
type, size and code identication of the section
order number /year of production
weight
wiring (electric system)
electric protection
The label also includes technical parameters of given
section. The user must make sure, that all labels on the
machine are readable and undamaged during whole
operation time. In case of damage of label conserning
safe use, repair it at once.
Informative and safety labels
FP units and separate sections are further provided with
informative labels showing the function of the device,
wiring schemes, media inlets and outlets and producer
labelling.

Service access to units
Unit construction provides
combinations of sides of ener-
gy connection and service
accesses. Connection side is
always given according to the
direction of air ow. (picture 1)

Warning symbol „Other danger“ is placed on the outside of
the unit on the service door and it calls attention to hazard
of interception with moving objects.
