2.2.2
Setting up the unit
All national and local regulations must be heeded when installing and setting up the unit. The unit
may only be installed in compliance with national installation regulations. Assembly and installation
shall be carried out in accordance with general local building, safety and installation regulations
applicable in the community or mandated by the water and electricity department or other bodies.
The ventilation unit is designed for upright installation and may only be set up on a suitable, load-bearing floor.
The unit may not be subjected to vibrations and the customer shall provide suitable structural acoustic
decoupling between unit and building.
Permissible reasonable maximum lifting capacities of persons and lifting equipment must be noted when
transporting the ventilation unit.
Suitable permanent drainage of condensate arising during operation of the ventilation unit will be required,
including effective odour blocking traps (siphon). Ensure adequate spacing between the base of the unit and
the floor.
Positioning, electrical connections and installation and connection of water, heating and condensate lines shall
be performed by specialists only. To prevent damage to the building, competent connections, tightness of
connecting lines and condensate discharge, including effective drainage and siphoning must be ensured.
Effective condensate drainage must be tested on site prior to commissioning and after servicing the unit.
Components of the ventilation plant, e.g. air ducts with fitted components, optional heating batteries with
accessories which may need to be installed in unheated areas, must be suitably insulated to prevent heat loss
or condensate formation (for temperatures under dewpoint). Suitable measures must be taken to ensure
automatic, reliable and frost-free operation if a risk of frost exists in assemblies and components.
Local building, safety and fire protection provisions, including statutory regulations and standards, must be
complied with. If necessary, appropriate measures should be taken when installing the units on site, e.g. by
including fire shutters in air ducts, etc.
2.2.3
Electrical connections
Electrical connections and work on electrical components of the unit and its accessories shall only
be carried out by authorised electricians and in compliance with national and local regulations.
Before opening the unit for any servicing or repairs etc., isolate the unit from mains (isolate all
poles of the power supply!) and secure against accidental switch-on before work on the unit is
complete.
The ventilation units are designed for a 230 V/50 Hz or 400 V/50 Hz supply (as shown on the nameplate, among
other). Potentially unsafe operations are prohibited. To ensure safe operation, never remove or bypass safety
devices.
The electrical systems of the unit, including their warning and protective functions, shall be regularly checked for
perfect operation. The unit must be shut down immediately in the event of malfunctions or defects such as loose
connections or overheated cables. Only original fuses with the prescribed rated current and dimensions may be
used.
Damaged or faulty power supply cables to the unit must be repaired immediately, to avert potential danger.
The unit may not be operated unless safe operational conditions have been restored.
Fault finding and immediate remediation of electrical defects and malfunctions shall be carried out by
authorised electricians only. All protective systems must be checked (e.g. earth resistance etc.) after
completion of electrical work on the unit.
