1 General
1.1 About these instructions
These instructions ensure the safe and efficient handling of this equipment. These instructions form an integral part of the
equipment and have to be kept in the direct vicinity of the equipment and available to personnel at all times.
All personnel must have carefully read through these instructions prior to commencing all work on the equipment. A funda-
mental prerequisite for safe working is compliance with all the stated safety instructions and other instructions contained in
this manual.
In addition all local occupational health and safety at work regulations apply, as do general safety provisions governing the
use of the equipment.
Illustrations in this guide are intended to provide a basic understanding and may differ from the actual model.
Ongoing tests and further developments may result in small variations between the unit supplied and the instructions.

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.
Any use beyond or other than the stated intended use is considered as misuse.
Any change to the unit or use of non-original spare parts will cause the expiry of the warranty and the manufacturer’s liabil-
ity.
Information in accordance with UL60335-1
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. This unit is intended for perman-
ent connection to a heating water circuit, and may not be connected using hose sets.
The water network needs to include safety measures to prevent the danger of overpressure.
This unit is not intended to be accessible to the general public. The water network needs to include safety measures to
prevent the danger of overpressure.

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).
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
Wall HK are decentralised units for heating, cooling and filtering 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 dis-
charged into the room through the air outlet grille.
