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 pump.

Safety Valve

The safety valve limits the maximum operating pressure to 335 Bar. If the maximum operating pressure exceeds the specified limit due to closing of the spray handle or due to nozzle clogging, 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 which has not been emptied completely of water.

To protect the machine against frost it must be stored free of water. Please empty the filter from animator and use compressed air (max 8bar) at the pump entrance.

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)
Maximum oil level from the high-pressure pump is on the top mark of the oil dip stick or in the middle of the window.
Do not overfill the pump with oil.
Electrical mains voltage/frequency should be the same with the electrical data of the machine. Recommended ship-side breaker: 25A, class D or K.
Check 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.

The high pressure flat or rotor nozzle must under no circumstances touch the surface for any manual cleaning or chipping/scrapping purposes!
High pressure nozzles and lances are not designed for such purpose and damaged components will create safety risk.

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.
Minimum input feed water requirement is an average of 16 liters/minute or 960 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 24.

Electrical connection

The voltage shown on the motor plate should correspond to the source.

380 V/50 Hz/3 ph – max 25 A, class D or K. (suitable for motor starter)
440 V/60 Hz/3 ph – max 25 A, class D or K. (suitable for motor starter)

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 4mm2.

Operation

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

Connect the 4pin plug 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.
Push the green start button, the machine will start.
In case the machine stops after 2-3 seconds it means water supply is poor. Please ensure input feed water requirement is 16 liters/minute or more.
Activate spray handle trigger. The pump at first empties the machine from air and particles. After a while, water comes out of the spray lance. Hold firmly the handle until a steady amount 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 300+ is now ready for operation at 300 bar.

Stopping

Close spray handle.
Push the red stop button.
Shut off water supply.
Pull spray handle trigger to release the line from remaining pressure.
Disconnect the machine’s electric plug 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
The machine should not run on standby mode for more than 20 minutes.
If the machine is no longer in use it must be switched off.

When spray handle is closed, machine is running in circulation-by pass mode. If in this working condition the water temperature exceeds 55°C the thermal valve opens, releases small amounts of hot water.
This is a safety component and should not activate in daily base.

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!

Weekly inspection – Testing

First oil change of high-pressure pump after 50 hours or 5 working days (8-10 hour shift) and then every 500 hours or 50 working days (8-10 hour shift).
Checking of oil level of high-pressure pump.
Checking of oil quality.
Replacing of water filter.

6-Month inspection

Inspect pump oil appearance and change oil after every 50 hours or 50 working days (8-10 hour shift), after the first change.
Check electrical board screws and tight in case of loose screws.

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 supplied water quality. In case of poor water quality and existence of particles and soil, the filter change should be done frequently – maybe even daily.

**** Disposal of oil from pump crankcase and disposal of parts and components of the machine should be done according to local regulations.
