2. Safety and regulations
2.4 Installation /
commissioning
- AccordingtoEN50110-1,onlyqualiedelectriciansmaycarryout
the installation and commissioning of the air handling control unit and
connected accessories.
- Observe all regulations stipulated by your local power supply utility and all
VDE or local regulations.
- DIN VDE 0100 Regulations regarding the installation of high voltage
systems up to 1000 V
- DIN VDE 0105-100 Operation of electrical installations
Where the system is not commissioned by Wolf, check all inputs and outputs
for correct wiring and function. For example:
- frost protection function
- fan rotational direction
- outdoor air dampers rotational direction
- plausibility of sensor values
- checking motor currents
- overload relay (thermal contacts / positor)
- airowmonitor
- ltermonitor
- function of heat recovery dampers (rotational direction)
- mixer air dampers (rotational direction)
- actuators, heating / cooling
- heating circuit pump / cooling circuit pump
- aswellasallothersystem-specicfunctions
The Wolf warranty will be void if the function test is not carried out correctly.
Danger due to live electrical components.
Please note: Turn off the ON/OFF switch before removing the casing.
Never touch electrical components or contacts when the ON/OFF switch is
in the ON position. This carries a risk of electrocution that could lead to injury
or death.
The supply terminals are 'live' even when the ON/OFF switch is in the OFF
position.
"Safety instructions" are instructions with which you must comply exactly, to
prevent risks and injuries to individuals and material losses.
The following symbols are used in these instructions. This important
information concerns personal as well as operational safety.
2.3 Symbols and warnings
"Please note" indicates technical instructions that must be observed to
prevent material losses and appliance malfunctions.

fIntended use
The Wolf KLM air handling and ventilation module is designed exclusively for
use in conjunction with Wolf appliances and Wolf accessories.
The Wolf KLM air handling and ventilation module is designed for the control
of air handling and ventilation systems.
It is normally matched to the system at the factory.
The BMK air handling programming module is designed for display and
operation of the KLM-XL air handling and ventilation module. The BMK is
available for mounting into the front of control panel doors (part no. 2744742)
and for wall mounting (part no. 2744743). Up to 2 programming modules can
be connected to one control unit.
The BMK- F remote control unit (part no. 2744751) is designed to start/
stop the system and to correct the fan speed, temperature and the fresh air
proportion. Furthermore, utilisation time extension and peak ventilation may
be activated. System faults are displayed on the remote control unit.
fImproper use
Any use other than the intended use is not permissible. Any other use or
changestotheproductatanytimeincludingduringttingandinstallation
invalidate all warranty claims. The user has sole liability for such use.
This appliance is not designed to be used by persons (including children)
withlimitedphysical,sensoryormentalcapabilitiesorwithinsufcient
experience and/or knowledge, unless they are supervised by someone
responsible for their safety or instructed by that person in the use of the
appliance.
