Fresh Air Boxes – ALB EC
Installation and Operating Instructions
• Only transport fans using means of transport that are appropriate for the weight,
wear protective gloves during transport!
• 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).
Frost protection information (only ALB EC WW)
ALB EC WW fresh air boxes have a warm water heater battery. In order to avoid
frost damage, heating water must always be available. The heating system must
be always in operation even if the ventilation system is turned off. In order to
guarantee that no cold outside air below +5 °C arrives at the heat exchanger,
an external damper must always be integrated in the ventilation system.
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
+35 °C. They are suitable for moving clean air without dust, grease, chemical evaporation and other pollution.
- Max. relative humidity: 80 %
- Electrical protection class: IP20
- Max. intake temperature without 40 °C
- Max. intake temperature with 20 °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 shutter (RSK, RVM (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.
