then endanger the life of the user and could cause the ignition of an explosive atmosphere. Consequently, Artidor as
the manufacturer will waive any responsibility.
2. Description
The window air conditioning system consists of a combined outdoor unit and indoor unit with remote control. In function
the system refrigerates air. The air conditioning system provides a continuous flow of cold fluid which decreases the
temperature of the heat exchanger, which in its turn absorbs the energy of the air, resulting in a room air temperature
decrease. The remote control enables the user to operate the indoor unit.
The part of the air conditioning system situated on the outside consists of a sheet steel enclosure and contains a heat
exchanger, a hermetically sealed compressor, one pressure regulated valve for controlling the refrigerant and NTC
temperature sensors. The sheet steel enclosure is partly part of the protection degree against ignition applied.
The part of the air conditioning system situated on the inside consists of a heat exchanger and NTC temperature
sensors all covered by a non-metallic hood. The electronically driven fan provides air flow on both sides of the system.
The infra-red remote control contains electronics (PCB) with a display and membrane pushbuttons all housed in a non-
metallic housing containing two (2) 1,5 V DC AAA dry cell batteries.
The ambient temperature allowed for the apparatus is -20 °C to +45 °C.
3. Characteristics
The characteristics can be summarized as follows:
Equipped with a H07 RN-F 3 x 1,5 mm² connection cable, length 5 meter
Manufactured on the basis of European Directive 2014/34/EU (ATEX 114);
Suitable for use in gas hazardous areas classified as zone 2;
Explosion safety category and protection against ignition applied: II 3 G Ex ic nAC h IIC T3 Gc;
Protection degree against ingress of water and dust IP54;
4. CE - Marking
The modification of the equipment to explosion-safe does not affect the conformity to the European Directives as
declared by the original equipment manufacturer in the original Declaration of Conformity.
With regard to explosion safety the air conditioning unit has been designed and manufactured on the basis of the
essential health and safety requirements of European Directive 2014/34/EU (ATEX 114) relating to Group II Category
3 G. Harmonized European construction standards have been applied fulfilling the essential requirements of the
directive. Please refer to paragraph 6 “Technical Data” and the Declaration of Conformity in the back of this user
manual for the applicable directives.
