3. Standards and regulations
According to DIN 1886, tools must be used to open the unit. Wait for the fan to
come to a standstill (2 minutes). When the doors are opened, negative pressure
may draw in loose objects, which could destroy the fan or even cause a risk to
life if items of clothing are drawn in.
Implement the electrical connection in accordance with local regulations.
Once electrical connection work is complete, the installation must be subjected
to a safety test in accordance with VDE 0701-0702 and VDE 0700 part 500,
as otherwise there would be a risk of electric shock that could result in injury
or death.
Before working on the unit, shut it down via the isolator (accessories).
According to the Machinery Directive (2006/42/EC), this unit requires an isolator
to be installed on site in the power cable.
The isolator must be
- lockable
- capable of interrupting all poles of the supply voltage
- designed as a supply disconnect device to EN 60204-1.
Voltage is still present at terminals and connections of the EC fans even when
the unit has been shut down. This means there is a risk of electric shock that
could result in injury or death.
Do not touch the EC fans for five minutes after disconnecting the power across
all poles.
Wolf CFL-WRG compact ventilation units are designed to heat and filter normal
air. Use of these units in rooms with explosive atmospheres is not permissible.
Handling very dusty or corrosive media is not permissible. Air intake temperatures
from -20 °C to +40 °C
The ventilation units, which are intended for indoor installation, must be placed
in rooms that meet the requirements of VDI 2050. (VDI 2050, Requirements
for technical equipment rooms - Planning and execution.)
These requirements include:
- For safety reasons, the room temperature in technical equipment rooms
must not fall below 5 °C (risk of frost) or exceed 40 °C.
- The unit should be operated in room conditions of between 22 °C and
28 °C at approx. 55 % relative humidity.
- Adequately sized maintenance areas must be provided.
Any on-site modification or improper use of the unit is not permissible and
Wolf GmbH accepts no liability for any damage caused as a result.
The unit does not present a direct risk of fire. The small numbers of seals fitted
inside the unit can burn away if subjected to external influences. If there is a fire,
disconnect the unit from the power supply, for example via an on-site smoke
detector. Wear respiratory equipment if you fight a fire. The usual extinguishing
agents such as water, extinguishing foam or extinguishing powder can be used
to extinguish fires. As there are only a small number of flammable seals, the
amount of noxious substances that could be released in a fire is minimal.
