alnor HRU-WALL-WI-150-60 Heat Recovery Units

General information

Description of the unit
HRU-WALL is a single alternate flow decentralized (single point) residential heat recovery unit, also called «push&pull» unit, designed to ensure adequate ventilation in enclosed environments without energy losses. It is recommended that two units are installed in pair: when one unit is pulling, the other is pushing. Pair of units can be installed in the same room or in different rooms (i.e. livingroom and bedroom). The unit is suitable for installation on an outside wall. The unit should operate continuously, and only stopped for maintenance or service. When heat exchange is not useful (for example in mid-seasons 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.

Safety

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 or damp hands/feet.
• This appliance can be used by children aged from 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 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 made by children without supervision.
• Do not use the product in the presence of inflammable vapours, 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, in accordance with 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 in order 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 in order 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 HAQCS 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.

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.
