1. General / safety information
Fire
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.
Recommended temperatures
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.

Electrical connection
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.
Intended use
WOLF CRL ventilation units are designed to heat and filter normal air. 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 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.
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).
According to DIN 1886, tools must be used to open the unit. Wait for the fan to
reach 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.
Removal and disabling of safety and monitoring equipment is prohibited.
Only operate the system in perfect technical condition. Ensure that any faults
or damage that may impact on safety are rectified immediately.
