3.1 Water connection
The water input is connected at the back of the machine. The machine can be connected directly to the mains water supply, or it can work as a self- priming unit*).
For direct water connection the inlet hose must be at least 6 m long, and the water temperature must not exceed 85°C. Please note that connection to the public water supply may entail mounting of a fl oat chamber.
If there is sand or other impurities in the water, it is advisable to provide an external water fi lter in ad- dition to the internal fi lter situated behind the quick coupling.
For connection of air motor, see section 9.0.
*) With cold water (up to 8°C) the cleaner will oper- ate satisfactorily with up to a 5 metre difference of level between cleaner and water supply.
The pump and the inlet hose must be connected to the water supply before starting up. When working with hot water (85°C) the cleaner must be below or on a level with the point of water supply. Working with hot water and connected to high pressure hoses longer than 10 m or inlet hoses shorter than 6 m, the cleaner must be equipped with a
float chamber. The same applies if the outlet of the cleaner is connected to a tube system.
4.0 Standard equipment
The cleaner is delivered with a double lance and a spray handle together with high pressure hose as standard equipment. The low pressure tube is equipped with a fl at jet nozzle 6530 and the high pressure hose with a fl at jet nozzle 1506.
The fi rst two fi gures of the nozzle reference number indicate the spray angle in degrees and the last two indicate the water fl ow in I/min. at a pressure of 20 bar and a temperature of 20°C. The equivalent hole diameters for nozzle 1506 is
1.6mm and for nozzle 6530 is 3.6 mm. Do not replace with nozzles of a smaller diameter. The maximum working pressure and temperature are printed on the standard high pressure hose. Only use Nilfi
The thrust on the nozzle is for: |

2603KLU | 31N | (3.2 kp) |
As the thrust forms an angle with the spray lance, the spray handle is subject to torque.
As standard equipment the cleaner is delivered with chemical injector for addition of detergents.
