Usage Features
The manual emphasizes several critical usage features and safety precautions:
- Pre-installation: Installers and users must read and understand the entire manual.
- Water Supply: Do not run the pump without water or with liquids containing solid particles. Auxiliary filters are recommended. The water supply pressure must be between 1.5 and 2.5 bar, and the water must be free from impurities. Do not use brackish or non-potable water.
- Temperature Limits: Avoid exposing the machine to freezing temperatures (below 0°C) or water temperatures above 40°C (104°F) or below 5°C (41°F). Complete emptying is recommended for prolonged inactivity in cold conditions.
- Electrical Connection: The electrical system must comply with local laws. A differential circuit breaker (30 mA sensitivity) is recommended. Do not use extension cords or loose plugs. Check the integrity of the electrical cable and equipment regularly. Do not touch the plug with wet hands or feet.
- Operator Training: The machine must be used by a properly trained operator. It should never be left unattended, especially with children around.
- Safety Gear: Operators must wear appropriate protective clothing, including goggles (or a protective mask), anti-slip boots, and safety gloves.
- High-Pressure Jet: Do not direct the jet at electrical sockets, the machine itself, people, or animals. The high-pressure jet can be dangerous if used improperly.
- Detergents: Use only liquid detergents recommended by the manufacturer. Other detergents may compromise safety and machine function. Rinse the circuit with clean water after using detergents. Do not use solvents, petrol, thinners, acetone, combustible oils, or toxic/irritant products.
- Total Stop Models: For models with "TOTAL STOP," the machine automatically stops when the gun trigger is released but remains powered. Do not leave it unsupervised without turning off the main switch, disconnecting the plug, and closing the water tap.
- Burner Operation: When using hot water, cool the machine with cold water for a few minutes before turning it off. The burner exhaust fumes are hot and considered a danger area; do not touch or cover the exhaust.
- By-Pass Operation: Do not leave the machine in by-pass mode for more than three continuous minutes.
- Trial Stage: New machines require a brief trial stage of 5 cycles, each consisting of 1 hour of operation followed by 1 hour of cooling.
Maintenance Features
The manual outlines a detailed maintenance plan, categorized into ordinary and scheduled maintenance, to ensure the machine's safety and efficiency. All maintenance and cleaning operations must be performed with the machine turned off and disconnected from the electrical supply. Only authorized spare parts should be used.
Ordinary Maintenance:

Every 750 hours:
- Replace: Pump oil, in-line fuel filter, fuel pump filter, electrodes, by-pass valve, safety valve, h.p. nozzle, quick couplings, spray gun, inlet water filter.
- Clean: Burner combustion, descaling.
- Adjust/Set: Fuel pressure.
Every 1000 hours:
- Replace: Pump valves, seal packing, oil seals, in-line fuel filter, fuel pump filter, fuel nozzle, electrodes, spark plug, ignition transformer, by-pass valve, safety valve, h.p. nozzle, quick couplings, inlet water filter.
- Clean: Fuel tank, burner combustion.
- Adjust/Set: Fuel pressure.
Specific Maintenance Procedures:
- High-Pressure Pump: Instructions are provided for removing and replacing valve O-rings, sealing gaskets, and ceramic pistons.
- Fuel Pump: Procedures for removing the fuel pump, checking/replacing the plastic drive, and addressing issues like low fuel level, worn electrodes, clogged filters/nozzles, and faulty ignition transformers.
- Heater: Instructions for cleaning soot from the heater cover and coil.
- Heater Adjustment: Guidance on adjusting the burner based on fuel/air temperature and altitude.
- Electrodes and Fuel Nozzle: Detailed steps for replacing electrodes and cleaning/replacing the fuel nozzle filter.
Troubleshooting:
The manual includes extensive troubleshooting tables for both the high-pressure pump and the heater/fuel pump, listing common problems, their causes, and solutions. This covers issues like irregular pressure, pump noise, water in oil, oil leakage, burner not starting, lack of vacuum, and unstable pressure.
Disposal:
The machine's demolition and disposal must be carried out by qualified personnel according to local laws. This involves emptying fuel and lubricating oil, rendering dangerous parts safe, and removing electrical components for recycling.
