1 General / safety information
In accordance with DIN 1886, tools are required to open the unit. Wait for the
fan to reach standstill (2 minutes wait). 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.
Make 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.
Even when the unit has been shut down, voltage will still be present at terminals
and connections of the EC fans. 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 CRL / CRL evo max ventilation units are designed to heat and filter normal
air. Max. Max. air intake temperature: +40 °C. The use of these units in wet
rooms or rooms with explosive atmospheres is not permissible. Handling very
dusty or aggressive media is not permissible.
Any onsite modification or improper use of the unit is not permissible and WOLF
GmbH accepts no liability for any damage caused as a result.
Ventilation units intended for internal installation must be placed in rooms that
meet the requirements of VDI 2050 (VDI 2050, Requirements for technical
equipment rooms - Planning and execution).
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. 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 level of pollutants that could be released in a fire is minimal.
Removal and disabling of safety and monitoring equipment is prohibited.
The system must only be operated if it is in perfect technical condition. Ensure
that any faults or damage that may impact on safety are rectified immediately.
The ventilation unit is designed for air intake temperatures between -20 °C
and +40 °C. 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.
