Product catalog summary
Purpose of the Device
The air curtain is designed for moderate and cold climates, maintaining indoor temperatures between -10 to +40°C. It prevents heat loss in winter and blocks hot air and pollutants in summer. It is suitable for large spaces like supermarkets and showrooms, with a required mounting height of 4 meters.
Basic Technical Parameters
Noise levels are specified at a 3-meter distance in open spaces.
Heat Output Ranges
There are two types of air curtains: those with water heaters (GUARD 100-150-200 W) and those with electric heaters (GUARD 100-150-200 E). Electric heaters use PTC coils, offering benefits like lower coil temperatures, automatic heat control, and reduced energy consumption.
General and Safety Principles
The air curtains comply with quality and safety standards. Key safety instructions include avoiding use in flammable environments, ensuring proper grounding, and disconnecting power before maintenance. Installation must be performed by a qualified electrician.
Installation
Installation considerations include ease of access for servicing and proximity to water and electricity supplies. The curtain can be mounted horizontally or vertically, ensuring no blockage of inlets and outlets. Proper leveling is crucial to avoid damage.
Control Panel
The COMFORT control panel manages airflow and temperature. It should be installed outside the airflow zone and can control up to two curtains.
GUARD Door Switch
This optional component allows the curtain to switch on/off based on door movement. It includes a relay cabinet and reed relay for indoor installation.
Diagrams of Electrical Connections
Electrical connections must comply with building codes and be performed by qualified personnel. The document provides diagrams for connecting single and multiple curtains to the COMFORT panel, detailing power supply requirements and control panel connections.
Connection and Operation
The GUARD air curtain can be used in cold curtain mode by switching off the electric heater. This requires a simple power cut-off installation using an on/off switch between the Comfort Panel and the GUARD curtain. The BMS communication module allows monitoring and control of the curtain via digital signals, enabling integration with any BMS master protocol.
Maintenance
The engine and fan are maintenance-free, but regular check-ups are recommended. The heat exchanger should be cleaned systematically, especially before the heating period, using compressed air. Anti-freeze liquid must be added to the water system if temperatures drop below 0°C.
Troubleshooting
Common issues include no heating or fan operation due to power supply problems, fan damage, or switch issues. Solutions involve checking power connections, replacing damaged components, and ensuring proper sealing of the heating system.
Guarantee Terms
The warranty covers material defects for 24 months from delivery. It excludes damages from improper use, installation errors, and natural disasters. Warranty services must be conducted by qualified personnel and documented in the Guarantee Card.
Complaint Procedure
Complaints should be lodged with the Distributor, and repairs are conducted on-site. Necessary documents include a complaint form, Guarantee Card, and proof of purchase. Costs for unjustified complaints will be charged to the customer.
