The Vallox Delico PTD AC control hood is suited to controlling AC roof fans and AC ventilation units.
The cooker hood is designed to be used above the cooker top, as a general extraction valve in the kitchen, and as a ventilation system control panel.

VENTILATION CONTROL

Apartment-specific ventilation units allows residents to adjust the ventilation efficiency. Ventilation is controlled based on the need e.g. through the cooker hood, ventilation control panel, or a separate control centre.
Away
The ventilation efficiency can be temporarily reduced when the apartment is unoccupied.
At home
Ventilation must be continuous, i.e. the air inside the building must be replaced at least once every two hours.
Boost
Cooking, sauna, bathing, drying of clothes, excessive heat, and other similar situations can require that ventilationbe increased from the standard setting.
In such a situation, ventilation must be increased.

USING THE COOKER HOOD

The cooker hood has a sliding part that can be pulled out of the cooker hood. Pull the sliding part out of the cooker hood for maximal extraction capacity.
Front panel buttons
The front panel of the cooker hood has four buttons and four signal lights. Position of the damper
The damper is opened by pressing the damper button (light turns on). The damper is closed (light turns off) by pressing the damper button or automatically after one hour (without a timer or 45-120 min when programmed). 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
when the load in the kitchen is exceptional e.g. due to the use of strong detergents or the presence of a large number of people.

It is recommended that ventilation be left turned on during long holidays also. This keeps the indoor air fresh and prevents humidity from condensing in the ventilation ducts and structures. It also reduces the riskof moisture damage.
CAUTION

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 air flow into the room if the cooker hood and non-electric devices are used simultaneously.

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 until the brightness is adequate.
Ventilation modes
Select the ventilation mode by pressing the ventilation mode button repeatedly until the signal light indicates the desired mode:
Away
At home
Boost
Selection button
The selection button is roughly 3 cm to the left from the damper button. The selection button is not marked on the front panel.

Other functions

Guard function
The cooker hood has 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, all signal lights and the LED light of the cooker hood will flash, the controlled fan or ventilation unit turns off, and the damper closes. If this kind of alarm is noticed before fire damage, it can be acknowledged by pressing any of the cooker hood buttons.
Pre-selection of light brightness
To modify the pre-selection of light brightness:

Turn on the light, close the damper, and set the ventilation to the Away profile.
Press the selection button for 10 seconds until the setting mode signal light starts to flash.
Adjust the brightness of the light by pressing the light button until the brightness is adequate.
To save the setting, press the selection button for roughly 3 seconds until the setting mode signal light stops to flash.

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.

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 (6.7 W). If the light is not working, contact a servicing company.
Removing and mounting the grease filter

VALLOX Delico PTD AC Control Hood - mounting

Pull the sliding part out of the cooker hood.
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

VALLOX Delico PTD AC Control Hood - INSTALLATION

Install the right mounting strip similarly to the left. Where needed, install a cover strip behind the cooker hood to cover the opening. VALLOX Delico PTD
AC Control Hood - behind VALLOX Delico PTD AC Control
Hood - limiter Adjust the glass of the front panel to be level with the front surface of the cabinet door by using the limiter screws behind the sliding part.
CAUTION
The cooker hood must not be connected to a flue that is used for removing combustion gases (e.g. from awood- or gas-burning fireplace, cooker, or stove).
CAUTION
Regulations on leading extraction air outdoors must be observed.
CAUTION
The minimum distance of the bottom edge of the hood to an electric cooker is 400 mm andto a gas cooker 650 mm.

SETTING VENTILATION MODES

As the default factory setting, the following voltages have been set for the cooker hood:

Away 70 V
At home 135 V
Boost 230 V

To change these values, move the transformer wires to more suitable connectors (see the wiring diagrams).
CAUTION
Control voltages must only be modified by an electrician. VALLOX Delico PTD

MEASURING AND ADJUSTING THE AIR FLOWS

Standard 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.
Adjustment:
Cover the required number of holes in the damper with the magnetic strip that is delivered with the cooker hood.

Boost ventilation
The volume flow rate of the air inside the cooker hood is measured with the damper open based on the static pressure loss and the performance scheme of the cooker hood.

Measure the static pressure loss of the cooker hood. The measuring point must be located 2 times the duct diameter above the outlet collar of the cooker hood (see figure).
Determine the volume air flow based on the measured pressure and the performance scheme (with the damper open).
