    Warranty card ....................................31 This manual is designed for qualified professionals performing installation works on an AirVents AVS CFP ventilation unit. Persons that have sufficient professional experience and knowledge on ventilation systems, their installation, as well as are qualified in electric security requirements and can work without causing collateral danger to others and the evnironment are considered qualified professionals.

  • Page 3: Safety Requirements

    SAFETY REQUIREMENTS This unit is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the unit by a person responsible for their safety. Children should be supervised to ensure that they do not play with the unit.
  • Page 4 AirVents AVS CFP Carefully read this manual before installing the unit. Ventilation units can only be installed by a qualified professional in accordance with the present user's manual as well as the provisions of all the applicable legal codes and security requirements.

  • Page 5: Unit Types And Sizes

    UNIT TYPES AND SIZES The unit’s main purpose is high-quality indoor ventilation. The ventilation unit extracts stale air from the room, along with the carbon dioxide accumulated in it, allergens, and dust, while also replacing it with fresh supply air purified by filtering. Since supply air is often colder or warmer than indoor air, the heat exchanger that is built in the unit takes heat from the extract air and recovers most of it to the supply air.

  • Page 7: Accessories

    ACCESSORIES Coolers and heaters Two cooling options are available with water or freon direct evaporative heat exchangers. Due to condensation that is formed as the air cools down, a drain pan is installed under the heat exchanger. If the air velocity in the ventilation unit is too high( >2 m/s), a droplet separator is installed that prevents condentsate from penetrating through other sections of the unit or air ducting system.

  • Page 8: Air Dampers

    AirVents AVS CFP Air dampers Air dampers are installed outside of the unit and attached with screws. Air dampers are designed to isolate and protect the unit from collateral air flows and drafts, when the unit is not operating. Moving plates of the air dampers are opened / closed using an actuator, whose power and torque are selected depending on the size of the air damper.

  • Page 11: Mounting

    MOUNTING Unit mounting site requirements AVS CFP ventilation units are designed for ventilation of large and medium-sized commercial and industrial premises (e.g. shops, offices, hotels etc.) where rated temperatures and humidity are maintained. The units are not designed to transfer airborne particulate matter. The standard air handling units are installed indoors.

  • Page 12: Space For Maintenance

    AirVents AVS CFP SPACE FOR MAINTENANCE The ventilation units may be mounted indoors. It is crucial to determine the right place to hang ceiling mounted units. Do not hang such units above stairs or too high, otherwise it will be impossible to reach them without special equipment.

  • Page 13: Connection Of Accessories

    CONNECTION OF ACCESSORIES The ventilation units are designed as monoblock units with additional accessories: heating, cooling, noise reduction, additional filtration. If, for some reason, the unit sections were disassembled while installing in the operational location, the unit's airtightness may not correspond to the data specified in the documents (unless the unit was assembled by the manufacturer’s qualified professional).

  • Page 14: Preheater Installation

    AirVents AVS CFP PREHEATER INSTALLATION Depending on the configuration, AVS CFP ventilation units may include different types of preheaters: water and electric heaters. Usually, heat exchangers are installed in separate sections along with preliminary filters, which are connected on the air intake side of the unit.

  • Page 15: Connecting The Heater And Cooler Sections

    CONNECTING THE HEATER AND COOLER SECTIONS All hydraulic system mounting operations, as well as connection to power mains must be performed by qualified personnel only. The circulation pump must be grounded. Avoid contact between the power cable and the pipes or pump. The flow direction of heat transfer and cooling media must be opposite to that of air flow.

  • Page 16: Connecting The Drain Pipe

    AirVents AVS CFP CONNECTING THE DRAIN PIPE When operating units equipped with counter-flow plate heat exchanger, with a heat recovery unit that uses an intermediate heat transfer medium, and units with cooling heat exchangers, condensation occurs, which is accumulated in purposefully designed drain pans.

    AirVents AVS CFP TRIAL RUN Only the accordingly trained and qualified personnel is authorized to carry out preparation, as well as the trial run of the unit. Proper functioning of the air dampers must be ensured before running the fans.

  • Page 19: Maintenance

    MAINTENANCE Air handling units are rated for continuous operation. Operation of the unit requires regular inspection, dry cleaning of internal components, checking and replacement of air filters in case of clogging. After the first 3-6 months of operation, a service technician should visit the unit for scheduled maintenance.
