General Information

Unit installation

Read this instruction manual thoroughly before starting installation.

• This unit complies with the low-voltage (EEC/73/23) and electromagnetic compatibility (EEC/ 89/336) directives.

• The installation should be carried out by a qualified installer.

• Follow all current national safety code requirements.

In particular ensure that a properly sized and connected ground wire is in place.

• Check that the voltage and frequency of the mains power supply are as required for the unit to be installed; the available power source must be adeguate to operate all other appliances connected to the same line. Also ensure that national safety code requirements have been followed for the main supply circuit.

• Where necessary, use field-supplied 25 mm I.D. PVC pipe of appropriate length and with the correct thermal insulation for the condensate drain extension.

• After installation thoroughly test system operation and explain all system functions to the owner.

• Use this unit only for factory approved applications: the unit cannot be used in laundry or steam pressing premises.

Choosing the installation site

Positions to avoid:

• Exposure to direct sunlight.

• Areas close to heat sources.

• On damp walls or in positions that may be exposed to water

hazard.

• Where curtains or furniture may obstruct free air circulation.

Recommendations:

• Choose an area free from obstructions which may cause uneven air distribution and/or return.

• Consider using an area where installation is easy.

• Choose a position that allows for the clearances required.

• Look for a position in the room which ensures the best possible air

distribution.

• Install unit in a position where condensate can easily be piped to an appropriate drain.

WARNING: Disconnect the mains power supply switch before servicing the system or handling any internal parts of the unit.

• The manufacturer declines any liability for damage resulting from modifications or errors in the electrical or water connections. Failure to observe the installation instructions, or use of the unit under conditions other than those indicated in Table "Operating limits" of the unit installation manual, will immediately invalidate the unit warranty.

• Failure to observe electric safety codes may cause a fire hazard in the event of short circuits.

• Inspect equipment for damage during transport. In case of damage file an immediate claim with the shipping company. Do not install or use damaged units.

• In case of malfunction turn the unit off, disconnect the mains power supply and contact a qualified service engineer.

• Maintenance must only be carried out by qualified personnel.

• All of the manufacturing and packaging materials used for

this appliance are biodegradable and recyclable.

• Dispose of the packaging material in accordance with local requiremements.

Avoid...

MAX 3 m

... any obstruction of the unit air intake or supply grilles.

ENGLISH

MAX 3 m

... exposure to direct sunshine, when the unit is operating in the cooling mode; always use shutters or shades. ... positions too close to heating sources which may damage the unit.

... exposure to oil vapours.

... installation in areas with high frequency waves. ... only partial insulation of the piping.

MAX. 200 mm

... connecting condensate piping to sewage system drain without appropriate trap. Trap height must be calculated according to the unit discharge head in order to allow sufficient and continuous water evacuation.

Non-level installation which will cause condensate dripping.

... ascending sections of condensate drain piping. These may only be used near the unit with a maximum height difference of 200 mm from the top of the unit.

... horizontal sections or curves of condensate drain piping with less than 2% slope.
