INTRODUCTION The user’s manual consisting of the technical details, operating instructions and technical specification applies to the installation and mounting of the sound-insulated fan VENTS KSB (hereinafter referred to as «the unit»). PURPOSE The fan is intended for supply and exhaust ventilation of household, public and industrial spaces with stringent noise generation restrictions and limited installation space.
DESIGNATION KEY Vents KSB 100 S M U1 R K1 Insulation _ - PU foam insulation. K1 - mineral wool insulation. Connection to power mains _ - equipped with a terminal box. R - equipped with a power cord with IEC C14 plug.
DESIGN AND OPERATING LOGIC Impeller Terminal block Sound insulating material Electronic control unit (option) Electric lead-in Mounting bracket Casing Fig. 2 The fan casing is made of galvanized steel sheets internally lined with heat- and sound-insulation layer. The round spigots are rubber sealed for airtight connection to the air ducts, Fig. 2. The fan is equipped with a bipolar asynchronous motor with an external rotor and a centrifugal impeller with backward curved blades.
www.ventilation-system.com MOUNTING AND SETUP The inline fan KSB is designed for direct connection to round air ducts. The casing has mounting brackets to facilitate the fan installation. In case the fan is mounted on flexible joints attach the fan to a structural unit by means of supports, suspension links or brackets.
CONNECTION TO POWER MAINS DISCONNECT THE FAN FROM POWER SUPPLY PRIOR TO ANY ELECTRIC INSTALLATION OPERATIONS. INSTALLATION SHALL ONLY BE PERFORMED BY A PROFESSIONAL ELECTRICIAN QUALIFIED FOR UNASSISTED OPERATIONS WITH ELECTRICAL INSTALLATIONS UP TO 1000 V AFTER CAREFUL STUDY OF THE PRESENT USER’S MANUAL. THE RATED ELECTRICAL PARAMETERS ARE STATED ON THE RATING PLATE.

CONTROL Depending on the configuration the fan may be equipped with an electronic temperature and speed control unit, Fig. 6. KSB fan is a perfect solution for ventilation of premises requiring permanent temperature control (i.e. greenhouses). The fan is equipped with an electronic temperature and speed control unit and automatically changes the impeller speed (air flow rate) with respect to the temperature in the ventilation duct or in the premise.
www.ventilation-system.com Example of the temperature sensor feedback delay: Initial Conditions: Rated rotation speed is 60 % of the maximum speed. Set temperature point is +25 °C. Air duct temperature is +20 °C. Fan impeller rotation speed is 60 %. Air duct temperature increases. Fan impeller rotation speed is 60 %.
Air duct temperature increases, reaches +25°C and continues to grow After the timer stops, the motor switches to the high speed 100%. After the speed switch the timer starts 5 minutes countdown. Thus, in the timer delay pattern the delay timer activates each time the fan speed changes. TECHNICAL MAINTENANCE Disconnect the fan from power mains prior to any maintenance and repair operations.
