1. Introduction
Congratulations - you have purchased one of the most durable and reliable
high pressure cleaners available on the market. Its balanced ratio of water flow
and working pressure perfectly meets all cleaning requirements. The high
pressure cleaner conforms to all European safety regulations which is
guaranteed by the CE symbol.
This manual to be made available to the operating personnel and to be
read completely before start-up. We point out that we cannot be held
responsible for any damage or malfunctions as a result of ignoring this
manual.

2. Safety Instructions
The following instructions to be followed before, during and after work:
This instruction manual to be read completely before initial start-up. If strictly followed,
no danger should occur.
This machine must only be run by qualified adult persons who are fully familiar with
possible dangers. Relevant national safety rules to be followed.
The machine is not suitable for unattended operation and must be operated according
to specification. Protective clothing to be worn.
The water jet emerging from the spray pistol has a dangerous cutting effect. Therefore the water jet must never be directed onto persons, animals or electrical installations. It must never be used for cleaning of clothes, footwear and the like. Be aware of
torque and recoil. Ensure stable foothold.
The max. allowed pressure which is stated on the type plate must not be exceeded.
The unloader valve opens, if the max. operating pressure is exceeded by more than
10 % and returns the water into the suction side of the high pressure pump. The
unloader valve is workshop-set and sealed. Adjustment must not be changed.
Unsuitable respectively defective high pressure hoses often cause severe accidents
during operation. Therefore high pressure hoses to be carefully inspected before
start-up and replaced by original equipment in case of damage. Use of other than
original equipment which has not expressively been approved by the manufacturer,
results in expiration of the CE Declaration of Conformity, as well as product liability
and warranty.
Used or damaged high pressure hoses must never be repaired and reused but to be
replaced by original hoses.
Spray pistols with delayed closing mechanism must not be used because of risk of
injuries.
Lever of pistol in open position must never be blocked or fixed in any way.
The use of spray wands shorter than 750 mm is prohibited.
The machine must not be run in areas jeopardized by fire or explosions. During
operation at filling stations “Technical Rules for flammable Liquids” (TfbF) to be
observed.
Consumables like detergents or lubricants to be handled thoroughly according to
technical rules and safety and environmental regulations to be observed.
Machine must not be started, if power cable, plug, switches, etc. are damaged or
defective.
Only extension cables designed according to IEC to be used. Extension cables on
reels to be completely reeled off during operation in order to avoid overheating of the
cable. Plug, couplings to be watertight. A faulty current protection switch to be
foreseen in electricity supply.

Before opening the machine in case of malfunction or emergency, switch off by
means of the ON/OFF switch and disconnect it from electric power source.
Electric power can cause severe injuries or death. All symptoms of faulty electric
components to be taken seriously and possible causes for accidents to be eliminated
immediately. All repair work only to be carried out by qualified service personnel.
Make sure that the machine cannot move. The unit is equipped with a parking brake
which must be set during working.
During loading hoisting device to be fastened properly at jack rings. Ensure balanced
load.
Repair work in the high pressure section of the machine (pump, hoses, piping) only to
be carried out by qualified personnel.
After work the machine to be locked and secured against unauthorized/accidental
operation by means of the pistol lever safety lock.
Use of equipment and/or consumables which is/are not delivered or
expressively approved by the manufacturer results in expiration of the CE
Declaration of Conformity, as well as product liability and warranty.

3. Configuration, Operation, Illustration
The cold water machines of this series mainly comprise of a low speed high
pressure inline plunger pump, which is directly flanged to and driven by a
100 % duty electric motor.
The supply water is directed with the required minimum pressure via a prefilter to the high pressure pump which – in connection with the required spray
nozzle – boosts it to the stated/adjusted working pressure. In order to protect
the pump against cavitation due to poor water flow, a low water cut-out is
arranged which stops the machine as soon as the flow pressure drops below
1 bar.
Downstreams of the high pressure pump a locked and sealed unloader valve
is installed which opens as soon as the operating pressure is exceeded by
more than 10 % and returns the water, which cannot be taken by the nozzle,
back into the suction line of the pump.
Model HPCExtreme 330 only: By opening of the rotary handle of the double
lance the working pressure can be adjusted as required.
The machine is equipped with a circulation shut-off system and additionally
with a thermo valve in order to protect the pump against overheating. After
closing the spray pistol the unloader valve opens, and returns the circulating
water back into the suction line. If during that procedure the water temperature
exceeds 60 °C, the thermo valve opens, releases a small amount of hot water,
and cold water can enter the pump. Re-starting and immediate generation of
required/adjusted working pressure is achieved by opening the spray pistol
again, allowing to continue the cleaning task without delay.
The range of applications can be extended by a variety of accessories
available. Contact your local UNITOR representative.
