DocumentDocumentMANUAL Manual Model Vallox Capto KTC A Type 279842 Document D3903 Valid from 1.1.2019 Updated 13.10.2021 The Vallox Capto KTC A cooker hood is designed to be used above the cooker top, or as a general extraction valve in the kitchen. The hood has a timer damper and a guard function. MANUAL VENTILATION CONTROL The removal of cooking smells can be enhanced by using the adjustment damper of the hood. Potential-free contact data and 230 V 4 A supply voltage are provided of the position of the damper. When Vallox Capto KTC A is connected to the joint extraction system of a multi-storey building, a Vallox Smoke Limiter must also be installed. WARNING! The unit is not intended for use by children under 8 or by persons with reduced sensory, physical or mental capabilities, or whose lack of knowledge and experience do not ensure safe operation of the unit. Such persons can use the unit under supervision, or by following the instructions of someone who is responsible for their safety. Do not let children play with the unit or to clean or maintain it without supervision. PLEASE NOTE! · Neglecting the cleaning of the grease filter can cause a fire hazard. · The outer surfaces of the hood can become hot when the cooker or the oven is turned on. · Flaming is forbidden underneath the cooker hood. · Always follow the instructions provided on adjusting the efficiency of ventilation. · Enable a sufficient supply airflow into the room if the cooker hood and non-electric devices are used simultaneously. USING THE COOKER HOOD The cooker hood has a sliding glass that can be pulled out of the cooker hood. It is recommended that the sliding glass be pushed or pulled from the aluminum strip on its front edge. Pull the glass out of the cooker hood for maximal extraction capacity. Front panel buttons The front panel of the cooker hood has three buttons. Position of the damper In normal circumstances, the damper must be closed (the signal light is off), which boosts the extract air flow from other premises. The damper must be open (the signal light is turned on) when the user wants to increase the extract air flow from the cooker hood e.g. · when the cooker top or the oven is used for cooking or · the load in the kitchen is exceptional due to the use of strong detergents, presence of a large number of people, or similar. Touch the button on the damper to open it and to start the timer. The damper will close automatically within 60 minutes. Other functions Guard function The cooker hood is equipped with a guard function that is activated when the temperature of the cooker hood exceeds 60°C or after a sudden increase in temperature (> 8°C/min). In such a case, the damper of the cooker hood closes and all signal lights of the cooker hood and the LED light will flash. If this kind of alarm is noticed before fire damage, it can be acknowledged by pressing any of the cooker hood buttons. Pre-setting of light brightness To modify the pre-setting of light brightness: 1. Turn on the light, close the damper. 2. Press the settings button for roughly 3 seconds until the setting mode signal light starts to flash. 3. Adjust the brightness of the light by pressing the light button until the brightness is adequate. 4. To save the setting, press the settings button for roughly 3 seconds until the setting mode signal light stops to flash. To read about the other functions of the settings button, go to our website, www.vallox.com. Cooker hood light Turn the light on or off by pressing the light switch. The light is dimmable. Adjust the brightness by pressing the light switch when the light is turned off until the brightness is adequate. Settings button The settings button is roughly 2 cm to the left from the light switch. 2 MANUAL MAINTENANCE Keep the cooker hood clean. Wipe outer surfaces regularly with water containing a small amount of a mild detergent. Clean off any grease stains immediately. Do not use abrasive or corrosive detergents or tools. Keep the grease filter clean to ensure an adequate extract air flow. The grease filter must be washed with warm water and detergent at least 1-2 times a month. Light The cooker hood has a long-lasting LED lighting module. If the light is not working, contact a servicing company. Removing and mounting the grease filter Removing the filter Mounting the filter · Pull the locking device of the grease filter towards the front edge of the cooker hood while pulling the grease filter downwards until it comes off. · Wash the grease filter and leave to dry. · Mount the grease filter back in place. Push the front edge of the filter into the pins on the cooker hood, and click the rear edge in place. NOTE! Ensure that the locking device points downwards. INSTALLATION In the example, the bottom of the sides and the rear of the cooker hood are level with the bottom of the top cabinets (see figures 1-2). In this case, a specially made cover panel is needed to hide the hood. The height of the cover panel is roughly 210 mm. The hood can also be installed higher, even so that it touches the frame of the spice cabinet. In this case, rear corners need to be sawn off from the spice cabinet frame (see figure 3). In this mounting method, the height of the hood cover panel is 100 mm. When the lowest possible mounting height is used, the bottom edge of the sliding glass, when pushed inside the hood, is level with the bottom of the top cabinet frames (see figure 4). The L strip is mounted on the wall as shown in figure 5. In this mounting method, the height of the hood cover panel is roughly 248 mm. Figure 1. Remove the spice cabinet. Mount the L strip on the wall so that it is level. The L strip fully covers the gap between the hood and the wall and also makes it easier to balance the hood in place during mounting. If the top cabinet frames are less than 305 mm deep, the longer edge of the L strip is mounted on the wall. The perforations on the lower surface of the L strip can be covered using white plastic studs. Figure 2. Place the hood on top of the L strip so that it is level and fasten the hood on the top cabinet frames with four screws. It is vital that the hood is both vertically and horizontally level. The front panel of the hood must be at the same depth as the outer surface of the top cabinet doors. Figure 3. If the highest possible hood mounting height is used, saw off diagonal pieces measuring at least 20x50 mm from the spice cabinet frame. Figure 4. The cooker hood when the lowest possible mounting height is used. PLEASE NOTE! The minimum distance of the bottom edge of the hood to an electric cooker is 426 mm and to a gas cooker 650 mm. Figure 5. Location of the L strip when the lowest hood mounting height is used. 1 2 3 4 5 min. 426mm / 650mm 50mm 38 mm 20mm PLEASE NOTE! · The cooker hood must not be connected to a flue that is used for removing combustion gases (e.g. from a wood- or gas-burning fireplace, cooker, or stove). · Regulations on leading extraction air outdoors must be observed. PLEASE NOTE! · The power outlet used for the cooker hood must be easy to access. 3 © Vallox Oy - All rights reserved MANUAL External electrical connection CONTACT DATA: GUARD FUNCTION: NORMAL SITUATION = OPEN ACTIVATED = CLOSED HOUSE AUTOMATION: NORMAL SITUATION = OPEN ERROR SITUATION (HOOD OR VENTILATION UNIT) = CLOSED ACTIVATED GUARD FUNCTION = FLASHING POSITION OF THE DAMPER: DAMPER CLOSED = CONTACT OPEN DAMPER OPEN = CONTACT CLOSED 3 POTENTIAL FREE CONTACT DATA 24VDC/5A RS 485 A B GND IN OUT IN OUT IN OUT + - ALARM FIRE ALARM MODE DAMP PIEZO TACHO GND 0-11V DAMPER LIGHT FAN PE N L 1 2 3 N L N L External feed based on the position of the hood damper. 230VAC/4A Terminal box on top of the hood L*LA LN GUARD FUNCTION HOUSE AUTOMATION POSITION OF THE DAMPER Measuring and adjusting performance values Standard ventilation Boost ventilation The volume flow rate of the air inside the cooker hood is measured with the damper closed and, where required, adjusted based on the static pressure loss and the performance scheme of the cooker hood. · Measure the static pressure loss of the cooker hood by pushing the probe through the hole in the damper (see the figure). · Determine the volume flow rate from the performance scheme based on the measured pressure and the number of open holes in the damper.
