Important information

To ensure safety and correct operation please read and observe the following instructions carefully before proceeding.
This document is part of the product and should be kept accessible as such. After commissioning, the document must
be handed out to the operator.
1.1

Warning and safety instructions

The adjacent symbol is a safety-relevant prominent warning label. All safety regulations and/or symbols
must be absolutely adhered to, so that any dangerous situations are avoided.
1.2 Warranty – Exclusion of liability
If the preceding instructions are not observed all warranty claims and accommodation treatment are excluded. This
also applies to any liability claims extended to the manufacturer.
The use of accessories not offered or recommended by Helios is not permitted. Potential damages are not liable for
warranty.
1.3

Certificates - Guidelines

If the product is installed correctly and used to its intended purpose, it conforms to all applicable regulations and CE
directives at its date of manufacture.
1.4

Shipping

The unit is packed ex works in such a way that it is protected against normal transport strain. Carry out the shipping
carefully. It is recommended to leave the unit until installation in the original packaging.
Do not transport the fan at connecting cables, terminal box or impeller!
1.5

Receipt

Please check delivery immediately on receipt for accuracy and damage. If damaged, please notify the carrier immedi-
ately.
In case of delayed notification, any possible claim may be void.
1.6

Storage

When storing for a prolonged time the following steps are to be taken to avoid damaging influences: Protection of motor
by dry, air- dustproof packing (plastic bags with drying agent and moisture indicators). The storage place must be water
proof, vibration-free and free of temperature variations. Storage temperature -20 to +40 C°, this limit must not be
exceeded.
When storing for longer than three months or motor standstill, the bearings must be inspected before commissioning.
In this respect, the silent, free movement of the impeller must be checked.
When transhipping (especially over longer distances) check if the packing is adequate for method and manner of trans-
portation.
Damages due to improper transportation, storage or commissioning are not liable for warranty.
1.7

Area of application

Use and operation only according to this installation and operating instructions. Using the fan to move heavily
polluted air or in potential hazardous areas is not allowed!
The MultiVent MV EC.. fans are designed for air ventilation and extraction in rooms and direct installation in duct sys-
®
tems. The fans are suitable for moving medium and small volumes of air against high resistances, at normal temperatu-
res from -20 °C to 60 °C (depending on type) and in the range of their performance characteristic curve. For operation
under difficult conditions i.e. high humidity, longer period of standstill, high pollution, excessive working conditions
through climatic, technical or electronic influences, further inquiry and operation release is necessary as the standard
version might not be suitable. The motors have tropical insulation. It must be ensured that the standardized range of
application is not exceeded.
m
The operational temperature (see rating plate) must not be exceeded!
m
The fan may not be used outdoors and may not come in contact with water during operation!
m
Use in explosive atmospheres is not permitted!!
1.8

Operation as room ventilation device

In order to achieve the desired fan performance a systematic air supply is imperative. When using chimney-dependent
fire-places in ventilated rooms these must have enough supply air no matter which operation conditions.
1.9

Performance data

The unit must be installed correctly to achieve the optimum performance. This applies to the installation of the unit, the
ducting and the supply air system.
– Electrical parameters
The motor rating plate provides information on the electrical data. This data must be examined for its conformity to the
local conditions.
– Air delivery
The fan performances were determined on a test stand according to DIN 24163, part 2; they are valid for the normal
design with free suction and discharge (straight duct section = 2x duct diameter). Diverging execution and adverse
installation- and operation conditions can lead to a reduction of performance.
