Fresh Air Boxes – ALB EC
Installation and Operating Instructions
2
• Wear protective gloves/footwear when unpacking the unit.
• Ensure the suitable load capacity and properties of the mounting surface and
use suitable mounting material.
• The operator is responsible for observing all plant-related safety regulations!
• Abnormally frequent activation/deactivation is not permissible.
• Once the rotating parts come to a standstill, a waiting time of 5 min. must be
observed, as dangerous voltages may be present due to internal capacitors
even after disconnection from the mains.
• Protection against contact for the impeller must be ensured pursuant to DIN
EN 13857.
• The planner and operator must ensure easy access for inspection and cleaning
work!
• A uniform inflow and free outlet must be ensured.
• When using vented fire places in a ventilated room, there must be sufficient supply
air for all operating conditions (consult chimney sweep).
1 .3 Area of application
– Normal use
The ALB EC fresh air box is designed specifically for direct installation in ventilation channel/duct systems and for ver-
satile commercial applications. The units are suitable for the use in dry interior rooms at temperatures from +5 °C to
+40 °C. They are suitable for moving clean air without dust, grease, chemical evaporation and other pollution.
- Max. relative humidity: 80 %
- Electrical protection category: IP20
- Max. intake tempe40 °C
The units are designed only for installation in frost-protected rooms. Frost and water damages may occur if installed
outdoors.
– Reasonably foreseeable misuse
The ALB EC fresh air box is not suitable for operation under difficult conditions, such as high levels of humidity, aggres-
sive media, heavy contamination, excessive loads due to climatic, technical or electronic influences. It is not intended
for use in a mobile unit (e.g. motor vehicles, aircraft, ships, etc.).
– Improper, prohibited use
Outdoor installation or in direct contact with water. Conveyance of explosive gas mixtures/media. Installation in an ex-
plosive area/atmosphere. Operation without standardised safety devices (e.g. protective grille). Conveyance of solids or
liquids. Conveyance of abrasive and/or fan material-corrosive media. Conveyance of conveyed medium containing fat.
1 .4 Boundaries
Spatial
A straight, flat pipe section of 500 mm must be ensured before and after the unit. When using a pipeline at the start,
the air inlets must be equipped with a damper RSKK, RSK, RVS (accessories). When using a pipeline at the end, a
protection grille must be used on the outlet side.
The outlet-side environment must not be accessible to unauthorised persons and obstructed.
The fan must be easily accessible for cleaning and maintenance purposes, particularly the terminal box.
Power supply interface
Connection only with permanently installed lines according to wiring diagram.
1 .5 Protection against contact
The generally applicable safety at work and accident prevention regulations must be observed for installation!
The operator is responsible for observing these regulations!
– Contact with rotating parts must be avoided.
– Protection against contact may be necessary on the suction side depending on the installation conditions.
Appropriate protection grilles are available.
– Fans which are protected by their installation method (e.g. installation in ventilation ducts or closed assemblies) do not
require protection guards if the plant provides the necessary level of safety. Please note that the operator is respon-
sible for complying with the current standard (DIN EN 13857) and can be held liable for accidents as a consequence
of missing protection systems.
1 .6 Personnel qualification
– All electrical work, commissioning, installation, servicing and maintenance must only be carried out by qualified elec-
tricians
– The unit can be used by children over the age of 8 as well as persons with physical, sensory, or mental disabilities or
lack of experience and knowledge, if they are supervised or instructed with regard to the safe use of the unit and they
understand the resulting risks. Children must not play with the unit. Cleaning or user maintenance must not be carried
out by unsupervised children.
