4 Installation

See Fig. 5 at the front of these operating and maintenance instructions.
4.1 a
ssemblIng the accessorIes
• The KA 2800 M are complete with a variable, fan-shaped nozzle-head (23) with a factory-installed
nozzle.
• For all other versions, fixed fan-shaped spray nozzle (27) must be assembled on the nozzle-head (24).
Make sure it is secured tightly using a 14mm pipe key (not supplied). Operation A in fig. 5.
• Screw the end of the high-pressure pipe (30) (the end without the quick coupling) onto the thread of
the cleaner gun (19) and tighten using two 22 mm keys (not supplied). Operation B in fig. 5.
• For the KA EXCEL versions, provided with the standard pipe reel, (11), the coupling (34) for the high-
pressure pipe (30) is connected to the coupling of the water outlet (15) in the factory.
4.2 c
ontrols and connectIon to the maIns water supply
CAUTION
• The water supply must be able to guarantee the adequate delivery of water flow to the high pressure
cleaner; refer to the table of technical specifications.
• In case of doubt, contact a Skilled Technician.
• Do not supply the high-pressure cleaner with water at a temperature in excess of 50°C/122°F or below
5°C/41°F.
• The pressure of the water supply must not be in excess of 8 bar/116 psi.
• Do not operate the high pressure cleaner with a priming depth in excess of 1.5m / 4.9 ft.
• Do not operate the high pressure cleaner if it is not connected to a water supply.
• Do not supply the high pressure cleaner with salt water or water containing impurities. In this event,
run the high pressure cleaner for a few minutes with clean water.
WARNING
• Follow current regulations for connection to the mains water supply in the country where the high-pressure
cleaner is installed.
4.3 c
ontrols and connectIon to the maIns electrIcIty supply
WARNING
• A Skilled Technician must check that the electrical supply complies with the data indicated on the
identification label on the high pressure cleaner (see Fig. 4). It is especially important that the supply
voltage does not differ more than ± 5% from that indicated on the label.
• All connections to mains electricity must be carried out by a Qualified Eletrician according to IEC 60364-1
regulations or the equivalent standard in the country where the high pressure cleaner is to be used. It is
especially important that the current outlet where the high pressure cleaner is connected is provided with
an earth conductor and a suitable fuse (according to the size indicated on the identification label and
in the table of technical specifications), and must be protected by a magneto-thermal differential circuit
breaker, whose sensitivity is not in excess of 30 mA.
• If the power supply cable is too short, an extension cord can be used provided it is not longer than
10 m / 32.8 ft, the section of the wires is at least 2.5mm² and the plug and the socket are waterproof.
Contact a Qualified Eletrician so that all these requirements are followed.
The use of unsuitable extension cords can be dangerous.
