2. SAFETY
>> The heat generator may only be worked on by contractors.
>> In accordance with VDE 0105 Part 1, work on electrical components may only be carried out by qualied electricians.
2.1 Intended use
Solid Air CPL ventilation units are designed to heat and lter normal air. The maximum air intake temperature is
+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 modication or improper use of the unit is not permissible and Solid Air GmbH accepts no liability for any
damage caused as a result.
If additional protective equipotential bonding is required due to structural requirements, this should be provided
onsite. The user or the certied electrician is obliged to ensure correct earthing of the appliances in accordance with the
applicable national and local electrical and installation regulations.
A conductive or non-conductive connection can be established between modules depending on the appliance
conguration. Modules with electrical equipment must always be connected with the earth conductor.
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). A contractor is dened as a qualied and
properly trained installer, electrician, etc.
The user is dened as somebody who has been trained to use the heat generator by a specialist.
The appliance may only be used up to an elevation of 2000 m above sea level.
The cables used in the unit are silicone-free and cadmium-free. They meet re safety standards of class Eca (DIN 60332-2).
2.2 Safety measures
Never remove, bypass or otherwise disable any safety or monitoring equipment. Only operate the heat generator if it is in
perfect technical condition. Any faults or damage that impact or might impact safety must be remedied immediately by a
qualied contractor.
>> All faulty components must be replaced with original Solid Air spare parts.
It may only be used for handling air. This air must not contain any harmful, combustible, explosive, aggressive, corrosive or
otherwise dangerous substances, as these would be distributed throughout the duct system or building, where they could
cause a risk to the health of, or even kill the occupants, animals or plants living there.
2.2.1 What to do in the event of a re
The unit does not present a direct risk of re. The small numbers of seals tted inside the unit can burn away if subjected
to external inuences.
>> If there is a re, disconnect the appliance from the power supply using the onsite smoke detector.
>> Wear respiratory equipment if you ght a re.
>> Use standard extinguishing agents such as water, extinguishing foam or extinguishing powder..

>> Wait until the fan comes to a stop.
>> Open the inspection doors carefully.
>> Notify an approved contractor.
2.4 Handover to operator
>> Provide these instructions and the other applicable documents to the operator.
>> Instruct the operator on how to operate the system.
>> Make the operator aware of the following:
•Annual inspections and maintenance must be performed by a contractor.
•Solid Air recommends concluding an inspection and maintenance contract with a contractor.
•Repair work must be performed by a contractor.
•Use only genuine Solid Air spare parts.
•Do not make any technical changes to the appliance or control components.

5. PLANNING
5.1 Siting the internal unit
• The installation site must be level and suciently load-bearing (at least 450 kg).
• The installation site must be able to bear the load of the ventilation unit without vibrations on a long term basis.
• Site the appliance in a room that is free from the risk of frost.
>> A clearance of at least 750mm for the CPL-1400 and 950mm for the CPL-2400, CPL-3300, CPL-4700 and CPL-6100 is
required in front of the appliance to be able to open the inspection doors. Approx. 700mm clearance is necessary
above the unit for air duct connections.
>> Level the unit horizontally (align using the adjustable feet).
>> Provide drain outlet for draining o the condensate.
5.1.1 Minimum clearance between outdoor air intake and exhaust air discharge to prevent an air short circuit

5.2 Siting the external unit (weatherproof)
Fig. 5.2 Siting the CPL-A external unit
Weatherproof units must not be used for any load-bearing building functions or as a replacement for
any part of the roof (VDI38035.1/DINEN130536.2).
5.2.1 Connecting the condensate drain pipe and PWW heat exchanger
•With weatherproof units sited outdoors, keep the condensate drain and DHW coil free of frost;
provide suitable protection if required.

6.4 Installing the outdoor unit
• Weatherproof units must not be used for any load-bearing building functions or as a replacement for any
part of the roof (VDI38035.1/DINEN130536.2).
>> The outdoor unit must be placed on a level horizontal surface with adequate load bearing capacity.
>> Base frames must be levelled horizontally (check with a spirit level).
• To prevent the inspection doors from jamming, the entire base frame must sit on the foundation.
Point loads are not permitted!
>> Provide permanently elastic noise insulation in the form of insulation strips between the installation
surface and the base frame. (This provides insulation against structure-born noise.)
