Description And Use; Installation - Vortice VHD Notice D'emploi Et D'entretien

ENGLISH
• The appliance must be installed by a professionally qualified electrician.
• The electrical system to which the product is connected must be in compliance
with applicable regulations.
• An omnipolar switch with a contact opening distance of 3 mm or higher should be
provided for installation, enabling complete disconnection under overvoltage
category III conditions.
• Products equipped with three-phase wiring (T) engines ALWAYS require
connection to 380-415V (or only 400V where required) three-phase lines, or also
220-240V (or only 230V where required).
• Any kind of modification shall be considered as product tampering and shall nullify
the relative warranty.
Duct and window - wall fan units
Precautions must be taken to prevent gas coming from the gas flue pipe or from
other fuel combustion units from entering into the room.

Description and Use

The requirements and characteristics of each fan model are determined in each case by the rules and regulations
established either locally or in general depending on the application in particular. Therefore in some cases
determinate units of a model may not be suitable for certain applications and can be modified in order to meet the
special characteristics of its purpose. For example, the units aimed to be installed in explosive or fire risk
environments must comply with the ATEX 2014/34/EU regulation and therefore must incorporate some sort of
protection system established by the law. The units aimed for the ventilation of emergency services in case of fire
must be homologated according to the UNE EN12101- 3/2002 regulation and comply with the CTE- Regulation
305/2011/CE (CPR). Also other common characteristics such as: high working temperature, corrosive environments,
etc. can also require a special modification in order to guarantee the correct functioning.
NOTE: The label of the fan will always specify any specific modificaion or purpose. Otherwise please contact Vortice.
The chosen model fan can never be used to convey another gas with different composition or temperature other than
Vortice specifications, nor work in different environment conditions than the specified.

Installation

In fans that are directly installed on the roof or wall, or those which use a supporting system or any additional
structure, should be levelled correctly horizontally and vertically. In horizontal bases such base should be flat and
levelled, and in cases where there is a concrete base it should be perfectly flat. In addition all the supports should
be checked so they are the most suitable ones and have enough strength to hold the weight of the fan as well as its
inertia when starting up. In the case of VHCDTE roof fans, special attention should be placed on reinforcing the
charging point of the fan and make sure that the waterproof property is not affected by the vibrations. The normal
vibrations caused while functioning depend mainly on the rigidness degree of the structural element where the fan
is placed. In this sense, it is highly recommended that in those models that there is this possibility, elastic shock
absorbers should be installed (either made with rubber or springs) to avoid transmission of vibrations and noises,
keeping the fan in a floating position. To complete correctly this insulation with the rest of the conducting installation,
elastic joints should be placed in the suctioning inlet and outlet of the fan. With this system the unit should be isolated
correctly, but always making sure such elements may not affect the compliance of security regulations. For rigid
instalments on concrete bases or walls that are not correctly aligned, never force the fan´ structure by tightening the
screws. Beforehand small strips of aluminium sheets, washers, or fast cement should be placed in the gaps to fill the
space ensuring the correct support of the fan.
