Safety Installations

Description and Function of the Safety Installations

• Unloader Valve for Bypass Mode
  • The high-pressure valve limits the operating pressure. When the maximum operating pressure is exceeded or the handle is closed, the unloader valve administrates the water over a bypass connector back to the water tank through the water diffuser.
• Safety Valve
  • The safety valve limits the maximum operating pressure to 550 Bar. If the maximum operating pressure exceeds the specified limit due to the closing of the spray handle the unloader valve receives a switching surge and channels the water through its bypass.
  • In case of excessive pressure more than the permittable limit for any other reason, the safety valve is activated and allows to leak through it, thus reducing the pressure.
• Protection against freezing
  • Freeze can destroy equipment that has not been emptied of water.
  • To protect the machine against frost it must be stored with antifreeze fluid filled inside the water tank. Fill approximately 4lt into the water tank and run the machine without high-pressure hose to fill the pump with antifreeze liquid.
  • To reach the antifreeze in all the parts please start the machine 2-3 times, till the antifreeze comes out of the high-pressure outlet.

Operating the machine

• Check points before start-up
  • Place the high-pressure cleaner on a plain and secure it against rolling.
  • Check the oil level of the high-pressure pump. If it is too low, refill oil. (Pump oil specification: SAE 15W40 ISO VG100 DIN 51524)
  • The maximum oil level from the high-pressure pump is on the top mark of the oil dipstick or in the middle of the window.
  • Do not overfill the pump with oil.
  • The electrical mains voltage/frequency should be the same with the electrical data of the machine. Recommended ship-side breaker: 50A, class D or K.
  • Check the general condition of the machine and accessories to be in good order (cable, power & water connectors, hoses, handle, lance, nozzle etc.)
  • Attention: Use only original nozzles with the machine.
• Water connections
  • Connect the water intake hose on the high-pressure cleaner.
  • Connection installed ¾’’ with GEKA coupling.
  • Always secure sufficient water supply, keep it well above the operational water flow. The minimum input feed water requirement is an average of 22 liters/minute or 1320 liters/hour
  • Insufficient water supply will cause machine to stop.
• Connection of high-pressure hose
  • Screw the female M22 coupling to the high-pressure outlet of the machine, use two spanner size 27 to fasten. The male 3/8” coupling must be screw to the inlet swivel of the spray handle, use one spanner size 22 and one 24.
• Electrical connection
  • The voltage shown on the motor plate should correspond to the source.
  1. 380 V/50 Hz/3 ph – max 50 A
  2. 440 V/60 Hz/3 ph – max 50 A
  • Use the correct dimension of electric cable wire in case you connect an extension cable. For cable extension lengths up to 50mtr, the cross section of the wire to be used is 6mm2.

Operation

The electrical system is equipped with direct online (DOL) starter.

• Connect the cable to the appropriate power supply.
• Connect the water supply hose to the ¾” GEKA coupling.
• Ensure that the lance is connected to the high-pressure hose without a nozzle.
• Open supply water tab and fill the water tank (air will bleed out of the filter through the water tank and overfill drain).
• Push the green start button, the machine will start.
• In case the machine stops after 2-3 seconds it means there is low water level in the tank.
• Activate spray handle trigger. The pump at first empties the machine from air. After a while, water comes out of the spray lance. Hold firmly the handle until a steady jet of water is ejected.
• Release the spray handle trigger and switch off machine by pressing the red stop button.
• Connect the nozzle into the spray lance.
• Push the green start button and the machine will start.
• Your Unitor™ HPCE Dynamis+ is now ready for operation at 500 bar.

HPCE Dynamis 500+ is a zero-pressure system in the bypass or power-off mode. When the machine is started the first time in each operation, there is a few seconds delay in the water jetting operation getting started. ALWAYS TARGET THE SPRAY LANCE TO A SAFE LOCATION ON THE GROUND EVEN IF THE WATER JETTING ACTION IS DELAYED BY FEW SECONDS (20-25s).

Stopping

• Close spray handle.
• Push the red stop button.
• Shut off water supply.
• Disconnect the machine’s electric cable from the electric power source.
• Store the machine and its accessories in a safe, frost protected and dry area away from harsh, corrosive environment.

Danger – Caution

• In case you stop work for more than 30 minutes, machine must be stopped.
• When handle is closed, machine is running in circulation mode. If in this working condition the water temperature exceeds 55°C the tank thermo valve opens, releases small amounts of hot water and same amount of cold water will enters.

Maintenance Plan

In order achieve a long and trouble-free service life the machine requires a minimum amount of care and maintenance. Maintenance works must be carried out only with stopped motor, disconnected power supply and pressure-free hoses. Danger of injury!

Daily inspection – Testing

For the safety of the machine and operator please check following points:

• Oil level at the pump.
• Visual inspection of the machine and its equipment/accessories (hoses, handle, lance, fittings, electrical components, other equipment).
• Inspection for proper air ventilation from the back of the motor.
• High pressure pump.
• Pressure gauges.
• High pressure hoses.
• High pressure handle.
• Electric cable.
• Function of Emergency stop button.
• Water filter, check and replace if contaminated or differential pressure exceeds 1bar.
• Check for leakages.

Weekly inspection – Testing

• First oil change of high-pressure pump after 50 working hours (hour meter is installed inside the electrical cabinet) and then every 500 working hours.
• Checking of oil level of high-pressure pump.
• Checking of oil quality.
• Replacing of water filter.
• Inspecting and cleaning of water tank mesh filter.
• After 30 operating hours, check electrical board screws and tight in case of loose screws.

6-Month inspection

• Inspect pump oil appearance and change oil after every 500 hours, after the first change.
• Check electrical board screws and tight in case of loose screws.
• Water tank to be drained and cleaned from inside.

12-Month inspection

• Pump oil seals and valves should be replaced at least once a year as a part of preventive maintenance for efficient machine performance.

Replacement of Water Filter

• Unscrew the plastic transparent cover of the filter housing with the included tool/spanner.
• Remove the old dirty filter and insert the new original 7” cartridge filter.
• Screw back filters housing with the supplied filter tool/spanner.

Time interval for replacing the filter depends on the supplied water quality. In case of poor water quality and the existence of particles and soil, the filter change should be done frequently – may be even daily. Disposal of the oil of the pump crankcase and disposal of parts and components of the machine should be done according to regulations.
