2 Safety
This section provides an overview of all important safety aspects to ensure optimum protection of personnel as well as safe
and trouble-free operation. In addition to the safety instructions in these operating instructions, the valid safety, accident pre-
vention and environmental protection regulations must be observed for the area of use of the unit. It is the duty of the oper-
ator to ensure that instructions relating to maintenance (e.g. relating to hygiene) are complied with.
2.1 Correct use
The units are only intended to be used for heating and cooling air in frost-free and dry rooms. Within the room, the unit
needs to be connected to the building's heating/cooling/ventilation system and to the building's waste water and power net-
work. The operating limits and limits of use described in Chapter 2.2 [}6] must be observed.
IMPORTANT NOTE!
Only use the unique after completion of the complete building and system. Site heating is not deemed to be
correct and proper use.
Intended use of the unit also includes adherence to these instructions.
Information in accordance with EN60335-1
This unit can be used by children aged 8 years or more and also by people with reduced physical, sensory or mental cap-
abilities or a lack of experience and knowledge, if they are supervised or have been instructed in the safe use of the unit
and the resulting dangers. Do not allow children to play with the unit. Do not allow children to clean and maintain the
unit without supervision.
The unit is not intended for operation above 2,000 m.a. s.l.
This unit is not intended for permanent connection to the drinking water supply system.

IMPORTANT NOTE!
Danger of frost in cooling mode!
There is a risk of the heat exchanger freezing when used in unheated rooms.
Make sure that the unit is equipped with a frost protection sensor and/or thermostat in this case.
IMPORTANT NOTE!
Warning of misuse!
In the event of misuse, as itemised below, there is a danger of limited or failing operation of the unit. En-
sure that the airflow can circulate freely.
Never operate the unit in humid areas, such as swimming pools, wet areas etc.
Never operate the unit in rooms with an explosive atmosphere.
Never operate the unit in aggressive or corrosive atmospheres (e.g. sea air).
Never operate the unit above electrical equipment (such as switch cabinets, computers or other electrical
units, or contacts that are not drip-proof).
Never use the unit as a construction site heater.
Never operate the unit in areas with a high dust content.
IMPORTANT NOTE!
Energy losses due to misuse!
Operating the unit with open windows (or other room openings) can result in significant energy losses.
Heating and cooling modes (particularly when operating different units) need to be coordinated with
each other.
2.3 Risk from electrocution!
DANGER!
Risk of fatal injury from electrocution!
Contact with live parts will lead to fatal injury from electrocution. Damage to the insulation or individual
components can lead to a fatal injury.
Only permit qualified electricians to work on the electrical system.
Immediately disconnect the system from the power supply and repair it in the event of damage to the in-
sulation.
Keep live parts away from moisture. This can cause a short circuit.
Properly earth the unit.

5.2 Brief description
Venkon XL are decentralised units for the heating, cooling and filtering of air, for use in hotels, offices and business premises,
among others. Secondary air is drawn in filtered by the fan and passed through the copper/aluminium heat exchanger. Here
the air is either heated or cooling depending on the temperature of the water in the heat exchanger. The heated or cooled air
is discharged into the room through the optional connection unit for circular pipes.

6.4 Installation
2 people are needed to install the unit.
CAUTION!
Risk of injury from sharp metal housing!
The inner metal of the casing can have sharp edges.
Wear suitable protective gloves.
IMPORTANT NOTE!
Horizontal installation of units!
When installing the units, ensure that they are completely horizontal to ensure proper operation.
IMPORTANT NOTE!
Avoid draughts!
Consider the occupied zone when installing/suspending the units. Do not expose people to the direct air
flow. Position the unit accordingly and adjust the air outlet if required.

6.4.1 Installation of basic unit
Note the Venkon minimum clearances when installing the basic units!
Highlight the dimensions and clearances of the key holes on the wall or ceiling as per the table, drill the holes and use
appropriate fixing materials to install the basic unit.
Align the basic unit for correct operation. Install the basic unit with a gradient on the condensation discharge side should
condensation be produced.
Once the basic unit has been aligned, prevent the fixing material from coming loose.
Venkon XL are fixed per unit at 4 points on the ceiling or on a construction provided by the customer. For this purpose, the
devices are suspended from the suspension brackets, e.g. from threaded rods (M8).
