General information

Description of the unit
HRU-WALL is a single alternate flow decentralized (single point) residential heat recovery unit, also called a «push» unit, designed to ensure adequate ventilation in enclosed environments without energy losses. It is recommended that two units are installed in pairs: when one unit is pulling, the other is pushing. A pair of units can be installed in the same room or in different rooms (i.e. living room and bedroom). The unit is suitable for installation on an outside wall.

INFO: The unit should operate continuously, and only stop for maintenance or service. When heat exchange is not useful (for example in mid-season when indoor and outdoor temperatures are similar), or when heat exchange is not recommended (for example with the option “summer free cooling”), it is recommended to set the unit in “extract-only” or “intake-only” mode and NOT to switch it off.

General safety instructions
This product was constructed up to standard and in compliance with regulations relating to electrical equipment and must be installed by technically qualified personnel. The manufacturer assumes no responsibility for damage to persons or property resulting from failure to observe the regulations contained in this manual.

Precautions for installation, use and maintenance

• The device should not be used for applications other than those specified in this manual.
• After removing the product from its packaging, verify its condition. In case of doubt, contact a qualified technician. Do not leave packaging within the reach of small children or people with disabilities.
• Do not touch the appliance with wet hands/feet.
• This appliance can be used by children aged 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning the use of the appliance in a safe way and understand the hazards involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be done by children without supervision.
• Do not use the product in the presence of inflammable vapors, such as alcohol, insecticides, gasoline, etc.
• If any abnormalities in operation are detected, disconnect the device from the mains supply and contact a qualified technician immediately. Use original spare parts only for repairs.
• The electrical system to which the device is connected must comply with regulations.
• Before connecting the product to the power supply or the power outlet, ensure that: the data plate (voltage and frequency) correspond to those of the electrical mains and the electrical power supply/socket is adequate for maximum device power. If not, contact a qualified technician.
• The device should not be used as an activator for water heaters, stoves, etc., nor should it discharge into hot air/fume vent ducts deriving from any type of combustion unit. It must expel air outside via its own special duct.
• Operating temperature: -20°C up to +50°C.
• The device is designed to extract clean air only, i.e. without grease, soot, chemical or corrosive agents, or flammable or explosive mixtures.
• Do not leave the device exposed to atmospheric agents (rain, sun, snow, etc.).
• Do not immerse the device or its parts in water or other liquids.
• Turn off the main switch whenever a malfunction is detected or when cleaning.
• For installation an omnipolar switch should be incorporated in the fixed wiring, by the wiring regulations, to provide a full disconnection under overvoltage category III conditions (contact opening distance equal to or greater than 3mm).
• If the supply cord is damaged, it must be replaced by the manufacturer, its service agent, or similarly qualified persons to avoid a hazard.
• Do not obstruct the fan or exhaust grille to ensure optimum air passage.
• Ensure adequate air return/discharge into/from the room in compliance with existing regulations to ensure proper device operation.
• If the environment in which the product is installed also houses a fuel-operating device (water heater, methane stove, etc., that is not a “sealed chamber” type), it is essential to ensure adequate air intake, to ensure good combustion and proper equipment operation.

Operation

The installation of the app and pairing of the device

Step 1.
Download the WallAIR Remote application from the Google Play or App Store and install it on your Android or iOS device. An app installed on the smartphone allows you to control a single heat recovery unit or a group of heat recovery units within range of the WLAN (Wi-Fi network) (Wi-Fi network).

Step 2.
Make sure all devices are within the router’s range.

Set the jumper in the App position.

Step 3.
When the heat recovery unit is turned on, it creates a Wi-Fi access point called HRU-WALL-150 which does not require a password. Connect the smartphone to this access point. Next, run the application and go to „Settings”.

Step 4.
Then select „Connect a new device”.

Step 5.
Select your Wi-Fi network and enter the password (to which the HRU-WALL-WI and smartphone/tablet will be connected).

Step 6.
Your smartphone should be reconnected to your Wi-Fi network. If this condition is met, the application will proceed to the next screen.

Step 7.
Select the room in which the device is installed. You can also add a new group.

Step 8.
Turn off the power to the heat recovery unit and set the jumper to RUN mode.

Step 9.
It is necessary to repeat the above steps for all HRU-WALL-WI-150-60 units.

Synchronization

• Synchronization of two or more units is done by adding these units to the same room in the application (see chapter 4. step 7.)
• You can change the synchronization options by clicking “Settings” in the application and changing the room selection.

Jumper positioning

• The integral jumper set in position A (Fig. 19A) means “extract-only” mode.
• The integral jumper set in position B (Fig. 19B) means “supply-only” mode.

The jumper position defines both the air-flow direction when the unit is activated for the first time (for the synchronisation) and the air-flow direction of the free-cooling mode.

Maintenance and service

• Maintenance can be carried out by the user as indicated at page 22.
• Service must be performed only by technically qualified personnel by local rules and regulations. Make sure that the main supply to the unit is disconnected (page 23).
• Cleaning of the heat exchanger can be performed from outside as well.

Disposal and recycling

• Information on disposal of units at the end of life. This product complies with EU Directive 2002/96/EC. The symbol of the crossed-out dustbin indicates that this product must be collected separately from other waste at the end of its life. The user must, therefore, dispose of the product in question at suitable electronic and electro-technical waste disposal collection centers, or else send the product back to the retailer when purchasing a new, equivalent type device.
• Separate collection of decommissioned equipment for recycling, treatment, and environmentally compatible disposal helps to prevent negative effects on the environment and on health and promotes the recycling of the materials that make up the equipment.
• Improper disposal of the product by the user may result in administrative sanctions as provided by law.
