Maintenance and cleaning
The system requires little maintenance, but to enjoy your system for many years to come, we recommend the following:

• NEVER use a high-pressure cleaner to clean solar shading This may damage the fabric, but it may also damage stronger metal or plastic parts
• If the fabric becomes wet due to an unexpected shower, you may simply roll up the screen, and then unroll it again in better weather to allow it to dry However, make sure not to keep the fabric rolled up wet for more than three days to prevent moulding and stains
• Remove loose dirt first using a brush or vacuum cleaner before washing down You can then remove the remaining dirt after using a cleaning agent and lukewarm water (special cleaning products are available from the installer) Always rinse off the fabric after cleaning Avoid cleaning in bright sunlight: if soapy water dries quickly, it can leave stains on the fabric Do not use any aggressive scouring agents
• Hinged or rotating parts need to be lubricated annually Use a dry lubricant for this (Teflon spray)
• Plastic sliding bushes can be lubricated using a dry lubricant (Teflon spray) after cleaning (remove twigs and leaves)
• As a manufacturer, we recommend a regular technical inspection of your installation by the installer:
  • → Annually for non-residential buildings;
  • → Every 4 years for domestic solar shading
• Always use original spare parts from the manufacturer
• Disconnect the Hirschmann plug inside the cassette when servicing or cleaning the surface behind the solar shading

B Ventilation systems: per residential unit vs collective applications

Ventilation systems per residential unit – which ventilation system do I have?
The capabilities of your ventilation system will depend on the configuration of the system? Please contact your DUCO installer if you do not know which ventilation system you have? A

DUCO Demand-controlled Ventilation System consists of the following:

• Central extract unit
  This unit extracts polluted air when necessary? With MVHR, the unit (DucoBox Energy) also supplies fresh air

• Air duct network

  • Via ventilation ducts to various rooms, polluted air is extracted to the ventilation unit (and fresh air is supplied in the case of MVHR)
  • Note: depending on the configuration of your system, not every room is directly ventilated Rooms in which no exhaust duct is provided are ventilated via transit to other rooms This can be done, for example, with a grille in the inner doors or an air gap underneath

• One or more sensors1
  CO2 and/or humidity sensors monitor air quality and detect presence Sensors can be incorporated into a remote control in the room, into air ducts or into the ventilation unit?

• One or more remote controls
  For manual operation of the ventilation system

• Window ventilators (Mechanical Extract Ventilation only)
  Fresh air is supplied via window ventilators integrated in the windows, window frames, sliding doors or façade Your ventilation system may include manual and/or Tronic (= electronically controlled) window ventilators Manual window ventilators require to be opened and shut by the user Tronic window ventilators are electronically controlled window ventilators which open and shut automatically as the system sees fit

You will need to leave manual window ventilators at least partially open in order to guarantee automatic system operation

Ventilation systems – collective applications
The only part here that needs regular maintenance (for better efficiency and longer life) is the Duco RoofFan

Duco RoofFan

Safety instructions and maintenance tips

• Do not carry out any maintenance work with the fan running Always disconnect the motor from the power supply first and secure it against being switched on again?
• Only trained personnel should carry out repair work
• Defects found must be rectified immediately If there is any acute danger, the system must not be used in the defective condition
• Wear safety clothing, safety shoes and cut-resistant safety gloves while working
• Observe the safety and working regulations (EN 50 110, IEC 364)
• Fuses should only be replaced and not repaired or bridged The data for the maximum fuse must always be observed (see Technical Data Sheet) Provide only the fuses planned in the electrical diagram Keep the ducts to the Roof Fan free of objects: danger from objects flying out
• Ensure vibration-free running
• Observe the limit values specified in ISO 14694 and, if these limits are exceeded, take measures to stop this (such as balancing by qualified personnel)
• The running wheel is subject to natural wear and tear Deposits on the running wheel can lead to imbalance and thus damage, such as tears, cracks and fractures Repair of the running wheel by e.g welding is prohibited
• Aggressive substances in the exhaust air can lead to corrosion and impeller breakage Corroded running wheels should be replaced immediately
• Deposits on the motor and in particular on the cooling ribs and in the recesses on the rotor can result in reduced cooling and the motor shutting down prematurely Therefore, remove deposits immediately
• The expected service life of the ball bearings integrated in the motor, determined according to the standard calculation procedure, is determined to a large extent by the service life of the grease F10h and amounts to approx 30,000-40,000 operating hours in standard application
• The fan and/or motor is maintenance-free thanks to the use of lubricated-for-life ball bearings The indicated service life of the grease may become shorter compared to the stated theoretical value (F10h) due to operating conditions such as vibrations, moisture or dirt in the bearing, unfavorable types of regulation, etc
• Bearings cannot be replaced In case of problems with the bearings, a completely new rotor must be installed

Cleaning

• Always disconnect the motor from the power supply first and secure it against being switched on again
• Clean the flow area of the fan
• Do not use aggressive, paint-dissolving cleaning agents
• Make sure that no water gets inside the motor and into the electronics (e.g through direct contact with seals or motor openings) Keep to the type of protection (IP)?
• Check the condensate drain holes (if present) matching the installation position for free passage
• In the event of improper cleaning procedures, no guarantee will be given in respect of corrosion / paint damage on unpainted / painted fans
• In order to prevent moisture accumulation in the motor, the fan should be driven for at least 1 hour at 80 to 100% of its maximum speed before the cleaning process!
• After the cleaning process, the motor should be driven for at least 2 hours at 80 to 100% of its maximum speed to dry it!

Gaining access to the rotor

1 De-energise the roof exhaust fan by turning the emergency load switch from the ON to the OFF position Ensure that the power cannot be switched back on by, for example, providing a mechanical lock on the emergency load switch| 2 Remove the lid of the roof exhaust fan by unscrewing the 4 Allen bolts
---|---
3 Remove the motor plate with rotor and control unit from the middle injection molding by unscrewing the 4 plastic screws| 4 Turn the motor plate with rotor and control unit 180° and place it on the middle injection molding Screw the motor plate back to the middle injection molding with at least 2 plastic screws to avoid shifting (and damage) during cleaning

Ventilation systems (per residential unit): overview maintenance

according to type of ventilation system

Always ensure that before maintenance work begins, the device is isolated from the mains supply by removing the power cord from the wall socket or by switching off the fuse Check by measurement that this is actually the case

A Mechanical Extract Ventilation systems (natural ventilation)

Maintenance frequency
RESIDENT INSTALLER

• Before (possibly) proceeding to clean your extract unit, as a resident, you need to inspect it to establish whether it is necessary
• Your central extract unit needs to be cleaned by an accredited installer
• In a newbuild home, the DucoBox needs to be cleaned completely, i.e including Box Sensors and Control valves (if present), after 6 months
• After these 6 months, you will need to repeat this operation every 3 – 4 years, depending on the degree of fouling
• If the central extract unit is used in combination with an extractor hood, then maintenance will be required more frequently than indicated above This will require additional maintenance, such as cleaning / replacing filters, the motor and the Box sensors plus Control valves, if present
• Technical maintenance of the DucoBox is not necessary

Filters

RESIDENT

• The filters of your DucoBox Energy should be replaced at least every six months
• NOTE: The filters require to be replaced within 3 months after initial commissioning in order to remove building dust and so on, even if the unit is not indicating it Failure to clean (sufficiently) or replace filters (on time) can lead to a poorly functioning ventilation system with unnecessarily high consumption, increased noise and unhealthy air for residents

Warranty on the unit will be void if:

• components not supplied by the manufacturer are used
•  the unit is used without filters

Cleaning the filters
In general, DUCO recommends cleaning the filters every 3 months If after 3 months it would appear that the filters are already too dirty, cleaning can be scheduled at shorter intervals
Navigate via the display to FILTER -> CLEAN FILTER and follow the steps described:

1. Remove the filter caps
2. Clean filters
3. Use a vacuum cleaner and move in the direction of the filter folds
4. Make sure that the filters are pushed back into the device in the same position
5. Close filter caps
6. Press enter ( )

Make sure that the filters are not rotated when they are removed for inspection or cleaning

Replacing filters
Replace filter indication
The system indicates that the filters need to be replaced by means of an alert on the DucoBox Energy display:

• Alert on display: “REPLACE FILTERS”, display stays lit up until the user takes action? This alert appears once?
• Alert on display, when the previous alert has been deleted by the user: alert symbol at the top of the display + filter indication shows 0%?

The estimated remaining service life of the filter is indicated in two ways:

• At the top right of the display is the filter indicator:
• FILTER: 20%
  • → 100% = new filter
  • → 0% = replace filter
• The estimated remaining life of the filter (expressed in days) can be read in the menu FILTER –> FILTER STATUS

Postponing filter replacement

• The alert symbol ( ) will remain visible at the top of the display by way of a reminder; furthermore, this filter indication will show 0%

You will not receive a new notification; you must take action yourself to replace the filters

Ordering filters
Filters can be ordered from your DUCO dealer There is a choice between the following sets:

0000-4742

The filtersets for the DucoBox Energy contain the following filters:
For supply air (SUP): choice between Coarse 65% (≈ G4) or ePM1 55% filter (≈ F7)? The ePM1 55 % filter allows fewer fine particles through, which has a positive influence on air quality (e?g? for people who may have allergies)?
For extract air (ETA): Coarse 65% filter (≈ G4)

Replacing filters

1. Step 1: order NEW filters
   To guarantee the unit’s correct operation and a healthy indoor climate, you are strongly advised against re-using contaminated filters (e?g? after vacuum- cleaning them)? This can result in a breeding-ground for bacteria and an unhealthy indoor climate!

2. Step 2: order the CORRECT filters
   Press enter ( ) when the message “REPLACE FILTERS” is visible and select YES, or navigate to the menu FILTER -> REPLACE FILTER?

When an “ePM1 (≈ F7)” filter is used, it must be used in the supply air flow (SUP)?

Depending on the version, the supply is at the following location:

• With a DucoBox Energy Premium:
• With a DucoBox Energy Comfort (Plus):
  The SUP position depends on the version: Left (L) or Right (R):

Version L or R can be consulted via the display: INFO -> DEVICE INFO Also make sure the filter is fitted correctly “L” and “R” on the filter must match the “L” and “R” on the front plate of the ventilation unit!

Step 3: Follow the instructions on the display when replacing the filters

1. Remove the filter caps
2. Replace the filters
3. Close the filter caps
4. Confirm using enter ( )

Ventilation ducts

INSTALLER

A Maintenance frequency

• Your ventilation ducts need to be cleaned by an accredited installer
• The contamination of the existing ventilation ducts can sometimes take on serious forms It is therefore necessary to clean the ducts on a regular basis, namely every 5-6 years for the supply air and about every 8 years for the exhaust air ductwork This can of course differ from situation to situation, depending on the extent of fouling

B How to clean

1. Remove the vents
2. Check the air ducts visually for contamination Dust and/or grease can adhere to the first section of the duct
3.  Clean the ducts with a damp cloth and use a bio-degreaser or soap water as appropriate Do not use solvents!

Control components and user controllers

RESIDENT INSTALLER

A Maintenance frequency

• Operating and control components require no maintenance during their service life However, operation may be impaired by air slot fouling Therefore, as a resident, regularly remove the dust from the casing with a dry duster or with a vacuum cleaner if necessary
• DUCO recommends a 3-yearly maintenance of its ventilation system control components by an accredited installer

B Battery-powered control

• The battery in a battery-powered controller lasts 3 to 5 years in normal use Battery type: CR2430 – 3 V
• Unscrew the user controller from the wall and unscrew the lid at the back to open it in order to replace the battery

Kitchen box

RESIDENT
As a resident, you need to carry out the inspection and cleaning yourself

.A Maintenance frequency
Check the Kitchen box (and vents) regularly (approximately once every 2 months) for fouling

.B How to clean

• Remove the inspection hatch by hand

• Clean the removable inspection hatch with a vacuum cleaner and then with a damp cloth (soap and water (eg a general-purpose cleaner))

• Clean the Kitchen Box with a damp cloth as soon as you notice any fouling
  Caution: the IAV valve is a 24 V powered item

• Take care not to change the setting and position of the vent control mechanism and the throttle valve If more than one vent has been mounted on the Kitchen box, make sure that the vents are not interchanged and that they are therefore placed back in the original ventilation opening in the Kitchen box All this may affect the flow rate and the proper functioning of the ventilation system

• Fouling on the inside, including on the throttle valve of the Kitchen box, is best removed by sucking out or cleaning using a vacuum cleaner, brush or (damp) cloth? Carefully check also for fouling that may have accumulated in the corners If so, remove it as well

• The inside of the duct can be cleaned with a vacuum cleaner

• Put the removable inspection hatch back onto the Kitchen box
