This installation manual concerns VEF 1, VEF 2, VEF 4 manufactured by Systemair UAB.

The cupboard fans are delivered with potentiometer, 0-10 V. The integrated potentiometer is factory preset to 10 V.

This value can be changed manually to obtain a different motor rpm/fan performance. An external potentiometer can

be connected if necessary. If so the internal potentiometer needs to be disconnected from the connection terminals.

This manual consists of basic information and recommendations concerning the design, installation, start-up and opera-

tion, to ensure a proper fail-free operation of the unit. The key to proper and safe operating of the unit is to read this

manual thoroughly, use the unit according to given guidelines and follow all safety requirements.

Cupboard fans are intended for transportation of air in air handling systems. The fans are meant for use in ducted sys-

tems and should always be duct connected on the inlet side. No moving parts shall be accessible after installation. Cup-

board fans are adapted to continuous operation.
