2. SAFETY
2.1 Intended use
Solid Air CPL-C 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
Solid Air accepts no liability for any damage caused as a result.
2.2 Safety measures
>>
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.
2.2.1 Power supply
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.
