Blauberg Box-I EC Inline Centrifugal Fan User Manual

Safety Requirements

⚠ IMPORTANT SAFETY INFORMATION ⚠

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.

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 use of the appliance in a safe way and understand the hazards involved.

Cleaning and user maintenance shall not be done by children without supervision. Children shall not play with the appliance.

Connection to the mains must be made through a disconnecting device, which is integrated into the fixed wiring system in accordance with the wiring rules for design of electrical units, and has a contact separation in all poles that allows for full disconnection under overvoltage category III conditions.

If the supply cord is damaged, it must be replaced by the manufacturer, its service agent, or similarly qualified persons to avoid a safety hazard.

Ensure that the unit is switched off from the supply mains before removing the guard.

WARNING: If there are any unusual oscillating movements, immediately stop using the unit and contact the manufacturer, its service agent, or suitably qualified persons.

The replacement of parts of the safety suspension system device shall be performed by the manufacturer, its service agent, or suitably qualified persons.

Precautions must be taken to avoid the back-flow of gases into the room from the open flue of gas or other fuel-burning appliances. The appliance may adversely affect the safe operation of appliances burning gas or other fuels (including those in other rooms) due to back flow of combustion gases. These gases can potentially result in carbon monoxide poisoning. After installation of the unit, the operation of flued gas appliances should be tested by a competent person to ensure that back flow of combustion gases does not occur.

Fixing means for attachment to the ceiling such as hooks or other devices shall be fixed with sufficient strength to withstand 4 times the weight of the appliance. The mounting of the suspension system shall be performed by the manufacturer, its service agent, or suitably qualified persons.

The appliance is to be installed so that the blades are more than 2.3m (2.1m AU) above the floor.

General Operations and Precautions

All operations described in this manual must be performed by qualified personnel only, properly trained and qualified to install, make electrical connections, and maintain ventilation units. Do not attempt to install the product, connect it to the mains, or perform maintenance yourself; this is unsafe and impossible without special knowledge.

Disconnect the power supply prior to any operations with the unit.

All user's manual requirements, as well as the provisions of all applicable local and national construction, electrical, and technical norms and standards, must be observed when installing and operating the unit.

Disconnect the unit from the power supply prior to any connection, servicing, maintenance, and repair operations.

Connection of the unit to power mains is allowed by a qualified electrician with a work permit for electric units up to 1000 V after careful reading of this user's manual.

Check the unit for any visible damage of the impeller, the casing, and the grille before starting installation. The casing internals must be free of any foreign objects that can damage the impeller blades.

While mounting the unit, avoid compression of the casing. Deformation of the casing may result in motor jam and excessive noise.

Misuse of the unit and any unauthorized modifications are not allowed.

Transported air must not contain any dust or other solid impurities, sticky substances, or fibrous materials.

Do not use the unit in a hazardous or explosive environment containing spirits, gasoline, insecticides, etc.

Do not close or block the intake or extract vents to ensure efficient air flow.

Do not sit on the unit and do not put objects on it.

Never touch the unit with wet or damp hands. Never touch the unit when barefoot.

BEFORE INSTALLING ADDITIONAL EXTERNAL DEVICES, READ THE RELEVANT USER MANUALS.

The installation site of the fan must have protective elements that prevent foreign objects from entering the fan.

When starting, setting up, and operating the fan, the exhaust and supply spigots must be protected to prevent injury from the rotating parts of the fan.

Disposal: The product must be disposed of separately at the end of its service life. Do not dispose of the unit as unsorted domestic waste.

Purpose

Mounting and Set-up

⚠ BEFORE MOUNTING ⚠

Make sure the casing does not contain any foreign objects (e.g., foil, paper).

Ensure convenient access for subsequent maintenance and repair.

Check the fan power cables for integrity and ensure the impeller has smooth rotation prior to mounting.

Models Box-I EC 30x15 to 50x30: These fans are mounted between rectangular air ducts and do not require special fastening if connected directly to them. Connect the fan to air ducts with M8 bolts and nuts.

Models Box-I EC 60x30 and larger: These fans are attached to the ceiling on anchors/studs or suspension brackets.

The fan may be installed in any position, considering the air flow direction (indicated by the arrow on the fan casing). Access for fan maintenance shall be provided. The casing is equipped with a removable access cover for maintenance purposes.

Connection to Power Mains

⚠ SAFETY FIRST ⚠

Disconnect the power supply prior to any operations with the unit.

Connection of the unit to power mains is allowed by a qualified electrician with a work permit for electric units up to 1000 V after careful reading of this user's manual.

The rated electrical parameters of the unit are given on the manufacturer's label.

The unit is rated for connection to 1~230 V/50 (60) Hz or 3~400 V/50 (60) Hz power mains according to the wiring diagram.

Connection must be made using durable, insulated, and heat-resistant conductors (cables, wires). The actual wire cross-section selection must be based on the maximum load current, maximum conductor temperature, wire type, insulation, length, and installation method.

The external power input must be equipped with an automatic circuit breaker (QF) built into the stationary wiring to open the circuit in the event of overload or short-circuit. The position of the circuit breaker must ensure free access for quick power-off. The trip current of the circuit breaker must exceed the maximum current consumption of the unit (refer to "Technical data" or unit label). It is recommended to select the nominal current of the circuit breaker from standard series, following the maximum current of the connected unit.

The circuit breaker is not included in the delivery set and can be ordered separately.

Technical Maintenance

⚠ DISCONNECT POWER ⚠

Disconnect the unit from power supply before any maintenance operations! Make sure the unit is disconnected from power mains before removing the protection.

Technical maintenance includes periodic cleaning of surfaces from accumulated dust and dirt.

Use a soft brush or compressed air to remove dust from metal surfaces of the fan. Use a vacuum cleaner to remove dust from the sound-insulating surface.

The impeller blades require thorough cleaning once in 6 months. Clean the impeller blades with a soft cloth wetted in mild water detergent solution. Avoid liquid dripping on the motor. Wipe the fan surfaces dry after cleaning.

While cleaning the fan, ensure the balance counterweights are not shifted and the impeller is not misaligned.
