VKV, VKH, VKV EC, VKH EC, VKMK, VKMKp, VOK, VOK The centrifugal fan VKH/VKH EC (fig. ) consists of the pan connected through a net to the base with the fixed electric motor and impeller on it. The VKH EC fan is equipped with a EC motor. The cover that protects the electric motor against weather factors is fixed to the base. The terminal box for connection of the fan to single- or three-phase power mains and placement of the operating capacitor is fixed to the upper casing part. The centrifugal roof fan VKMK/VKMKp (fig. ) consists of the casing and the flange. The impeller and the electric motor are placed inside the fan casing. The cover is attached to the casing with self-tapping screws. The terminal box for connection of the fan to single- or three-phase power mains and placement of the operating capacitor is fixed to the upper casing part. The axial fan VOK/VOK (fig. ) consists of the casing with a square flange (VKMK modification) or a plate (VKMKp modification). The impeller and the electric motor are placed inside the axial fan casing. The cover is attached to the casing with self-tapping screws. The terminal box for connection of the fan to single- or three-phase power mains and placement of the operating capacitor is fixed to the upper casing part. SAFETY REQUIREMENTS All electric connection, adjustment, servicing and repair operations must be done with the fan disconnected from power supply. Electric connection works must be done by a duly qualified electrician with a valid electrical work permit for operation up to 000 V units. Read this manual before starting any electrical works. Make sure of no visible damages of impeller, casing, grille and no foreign objects inside the casing that can damage the impeller blades. Misuse of the fan and any unauthorized modifications are not allowed. The unit is not to be used by children and persons with reduced physical, mental or sensory capacities, without proper practical experience or expertise, unless they are controlled or instructed on the unit operation by the person(s) responsible for their safety. The fans are not designed for operation in the environment containing flammable substances or vapours like alcohol, gasoline, etc. The fans are powered by single-phase 0 V/ 50 Hz (VKMK and VKMKp 0 V/ 50 Hz, 60 Hz) alternating current or by three-phase 00 V/ 50 Hz alternating current.
VKV, VKH, VKV EC, VKH EC, VKMK, VKMKp, VOK, VOK INSTAATION AND OPERATION GUIDEINES The fan is designed for mounting on a roof directly above a ventilation shaft or air duct. Installation procedure and mounting sequence are shown in fig. 5, 6, 7, 8, 9, 0. To prevent water and snow ingress inside a ventilation shaft the fan can be mounted on a roof curb. A roof fan can be connected to a ventilation shaft with an intake flange that is fixed directly to the fan base. The fan base has holes for fastening bolts for connection of the fan to the level surface or to the roof curb. The roof curb, intake flange and fastening bolts are not included into delivery set and are available upon separate order. Power supply to the fan is effected with an external terminal box or a terminal block integrated into the motor casing. The fan must be grounded. The terminal must be connected to the ground loop. Due to the constant improvements the design of some models may slightly differ from those described in this manual.

Connection to power supply must be done by a duly qualified electrician. The rated electrical parameters are shown on the rating plate. Any tampering with the internal connection is prohibited and will void warranty. Depending on the modification the fans are powered by single-phase 0 V / 50 Hz or 60 Hz or 00 V / 50 Hz alternating current. The fan must be connected through insulated durable and thermal-resistant wires (cables). The automatic circuit breaker incorporated into the fixed power network that breaks all the phases must be installed at the external electric input 0 V / 50 Hz or 60 Hz or 00 V / 50 Hz. The external circuit breaker location must provide free and unhampered access to the fan for quick switching off in case of need. The overcurrent protection must match the rated current consumption Of the fan.
7 VKV, VKH, VKV EC, VKH EC, VKMK, VKMKp, VOK, VOK The recommended automatic circuit breaker rated current and the cable cross sections for various fan types are stated in the table. The above cross sections are for reference only. The actual cross section depends on the cable type, maximum heating value. The fans with EC-motors are connected to power mains through the terminal block located inside the external or integrated terminal block in compliance with the wiring diagram and the terminal designation, see fig. 7 for VKV/VKH 50 0 EC; fig. 8 for VKV/VKH 55...560 EC. The terminal designations are shown on the sticker inside the terminal box. The recommended wiring diagram with motor overheating protection for singlephase motor is shown in fig. and for three-phase motor is shown in fig.. TW and TW terminals are the electrical leads of the normally closed contact of the motor overheating protection. This contact must be connected in series to the power circuit of the coil of the magnetic starter KM that starts the motor after pressing the button S. The contact is broken in case of motor overheating and it switches the starter coil off to cut power supply to the motor off. The automatic circuit breaker, magnetic starter KM, control buttons S and S are not included into the delivery set and are designed to be installed by the user.
