user's manual

Disconnect the fan from power mains prior to any connection, servicing and repair operations. Mounting and
maintenance are allowed for duly qualified electricians with valid electrical work permit for electric operations
at the units up to 1000 V after careful study of the user's manual.
The single-phase power mains must comply with the acting local electrical norms and standards.
The fixed electrical wiring must be equipped with an automatic circuit breaker. The fan must be connected to
power mains through an automatic circuit breaker QF integrated into the fixed wiring system with the gap
between the breaker contacts on all poles not less than 3 mm.
Check the fan for any visible damages of the impeller and the casing before starting installation. The casing
must be free of any foreign objects that could damage the impeller blades. Misuse of the device or any
unauthorized modifications are not allowed.
The fan 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 product operation by
the person(s) responsible for their safety. Do not leave children unattended and do not let them play with the
product.
Take steps to prevent ingress of smoke, carbon monoxide and other combustion products into the room
through open chimney flues or other fire-protection devices. Sufficient air supply must be provided for proper
combustion and exhaust of gases through the chimney of fuel burning equipment to prevent back drafting.
Transported medium must not contain any dust or other solid impurities, sticky substances or fibrous materials.
Do not use the fan in the environment containing hazardous or explosive materials and vapours, i.e. spirits,
gasoline, insecticides, etc. Do not close or block the fan intake or extract vents in order to ensure the most
effective air passage.

OPERATION GUIDELINES
The fan is designed for connection to AC single-phase 220...240 V, 50/60 Hz power mains. The fans
models VK 315 / VKS 315 are designed for connection to 220...240 V, 50 Hz power mains.
The fan is designed for continuous operation always connected to power mains.
The fan is rated for operation at the ambient temperature ranging from +1 °C up to +45 °C.
Air flow direction in the system must match the pointer direction on the fan casing.
Ingress protection rating against access to hazardous parts and water ingress- IP X4.
Transported air temperature:
- VK 100/ VK 100 Q/ VK 125/ VK 125 Q/ VK 150: from -25 °C up to +55 °C;
- VK 200/ VK 250/ VK 250 Q/ VK 315: from -25 °C up to +50 °C;
- VKS 200/ VKS 315: from -25°C up to +45 °C.
The fan requires no grounding.
ELECTRONICS OPERATING LOGIC
The VK U (U1) model, fig. 11 is equipped with an electronic speed controller with electronic thermostat
TSC for automatic speed control (air flow regulation) depending on air temperature.
-temperature-based control logic (VK U): to maintain air temperature with accuracy to within 2 °C. The fan
changes its speed rarely. As air temperature rises up to the set thermostat point, the fan switches to high
speed. As air temperature drops down 2 °C below the set thermostat point or if the initial air temperature is
The terminal compartment incorporates 2 control knobs:
- for setting the motor speed;
- for setting the electronic thermostat set point.
The thermostat operation light indicator is located on the fan cover.
To set the thermostat threshold rotate the thermostat control knob clockwise to increase or counter-
clockwise to decrease the temperature set point.
To set the fan speed (air capacity) rotate the speed control knob in the same way.
The fan has a temperature-based and timer-based control logic.

- timer-based control logic (VK U1): to maintain air temperature with high accuracy. The fan changes its
speed more often as compared to the previous control logic, but the minimum operating time at one speed
is not less than 5 minutes. As air temperature rises up to the set point, the fan switches to maximum speed.
Synchronously, the speed switch delay timer is activated for 5 minutes. As air temperature drops down
below the set point, but only after 5 minutes countdown after switching to high speed, the fan switches to
lower set speed.
If the initial temperature is below the set temperature point, the fan operates at low set speed from the start.
The fan VK P (fig. 12) is equipped with a speed controller that enables switching the fan on/off, smooth
speed (air flow) control from minimum to maximum value.
MOUNTING
The fan is designed for both horizontal and top installation and may be mounted on the floor or attached to
the wall or to the ceiling, fig. 2. While mounting the fan provide extra protection against water ingress.
The protection examples are shown in fig. 2:
1. For the top mounting position: install a protecting hood above.
2. For any mounting position: connect a straight air duct section at least 1 m long on both sides of the fan.
The fan mounting sequence is shown in fig. 3-8.
The fan wiring diagrams are shown in fig. 9.
