[. . . ] If the machine is connected to a pipeline with 2 users, the machine will automatically adjust the numbers of pumps to run. The nozzle size can be read from the data plate on the machine. 4. 1. 6 Application of detergents (external) If you want to apply detergents or disinfectants these should be dosed to the water through an injector. In conjunction with the injector it may be advantageous to use a wall rack on which spray lances, 2 pcs. of 25 l containers as well as 10 m high pressure hose can be placed. Below you will find various types of outlet points with injectors. Outlet point with detachable injector To be attached to the quick coupling of the high pressure cock. Dosage 1-8%. Outlet point with detachable foam injector To be attached to the quick coupling of the high pressure cock. To be used in conjunction with foam lance for application of high-foaming detergents or disinfectants. Outlet point with cleaning trolley and foam injector To be attached to the quick coupling of the high pressure cock. To be used in the same way as "Outlet point with detachable foam injector". 12 4. 1. 7 Application of detergents (internal) 2 This kind of detergent addition is an option. If the machine is mounted on a pipeline, detergent will come out of all outlet points. The pH value MUST be between 5. 5 and 8. 5. A 1 4. 2 Starting up 1. Check on the pressure gauge (5) that a pressure is being built up in the system. If a pressure is not being built up, vent the machine as described in section 3. 7 Venting. 0 1 5 3 2 S 4. 3 Operation automatic start/stop Always hold the spray lance with both hands!The machine is automatically activated when the trigger (1) of the spray handle is activated. When the trigger is released, the machine automatically stops after 20 seconds. When the machine is not in use, the trigger should be locked with locking device (see arrow). It can be restarted by pushing the green button (3). 1 13 4. 4 Double spray lance, pressure regulation The spray lance features 2 nozzles, a high pressure nozzle and a low pressure nozzle. 1 High pressure mode When the pressure reducing valve (1) is completely closed (turned clockwise - B), only the high pressure nozzle is used high pressure mode. Low pressure mode When the reducing valve (1) is completely opened (turned counterclockwise - A), both spray lances are used - low pressure mode / possibility of dosing detergents. The pressure may be regulated between these positions. 4. 5 Stop Danger of scalding!Never detach high pressure hoses at a water temperature above 50°C. 0 1 Never detach the high pressue hose while the machine is in operation. Close the shut-off cock of the water inlet and activate the spray lance or open the high pressure cock to relieve the pipeline / high pressure hose of pressure. 14 4. 6 Frost protection The machine should be installed in a frost-free room. [. . . ] If that does not solve the problem, the water supply for the machine > Oil shortage in pump DUO BOOSTER: > Water temperature too high (red lamp is on) Fuses blow > Installation does not correspond to the ampere consumption of the machine Working pressure too low > Nozzle worn > Wrong spray lance > Reduction valve of spray lance not adjusted to max. > Nozzle partly clogged up Working pressure fluctuating > Water temperature too high > Insufficient water supply 20 Symptom Reason Action Working pressure fluctuating (continued) is insufficient. > High pressure hoses too long · Dismount high pressure extension hoses and retry. · Repair leak. > Wrong nozzle > Air in the system > Water inlet filter clogged up No working pressure > Nozzle clogged up > No inlet water > High pressure cock of outlet point open.
