IMPORTANT INFORMATIONE.1
SafetyE.1.1
Never point the gun at yourself or anybody else and hold it with both hands when spraying. A highpressure spray can penetrate the skin causing serious injury.
Before service work, always disconnect the air supply.
When cleaning, it is strongly advisable to use protective goggles, wear protective gloves and protective
clothing.
Never spray electrical equipment or cables unless you are sure that the installation stands high-pressure
cleaning.
Be sure that any part to be tted withstands the pressure.
If the cleaning unit is to be used in a hazardous environment, earthing the equipment will eliminate
static electricity.
Airclean is CE-marked.
LubricationE.1.2
The air motor requires lubricated air. In order to ensure uninterrupted steady operation you must never
let the tted air lubricator run dry. The correct position of the adjustment screw is approx. 1/2-1 turn.
Air operating pressureE.1.3
Do not exceed maximum safe air operating pressure specied in data sheet, enclosure 1.
Frost protectionE.1.4
If frost is expected, the waterside must be emptied to prevent damage by frost. This is simple. Disconnect the water supply and let the unit run some strokes until the pump, hose, spray gun and extension
tube is empty. Or change over the air supply to the water intake and blow the waterside dry.
GuaranteeE.1.5
The guarantee is not valid for damages caused by erroneous usage or if the unit has been disassembled
without written permission from the manufacturer.

DESCRIPTION AND OPERATIONE.2
Pump unitE.2.1
The pump unit comprises a single acting pump powered by a double acting air motor. An air shuttle
valve that changes the air direction when the piston reaches the end positions controls the air motor.
Water inletE.2.2
The connection is marked “Water”. Use a water supply hose with minimum diameter as specied in
enclosure 2 “Dimensioning of water- and air inlet”. It is recommended to connect a low-pressure hose
of minimum 3 meters length to the water inlet of the unit to prevent shock in the water system.
The suction head capacity of the pump is reduced with increasing temperatures. Increased supply pressure may therefore be required when pumping hot water. The suction line must be free from leeks.
Claw couplings are not suitable for suction lines with pressures below atmospheric pressure.
Air inletE.2.3
The air connection is marked “Air”. Use air supply hose with minimum diameter as specied in enclo-
sure E.2 “Dimensioning of water- and air inlet”. Do not t valves, ttings etc. with less diameter than
specied in enclosure E.2. If regulation is required at the unit, it is recommended to t a full-bore ball
valve and use this for throttling the air supply. If you are going to use an air pressure regulator it must
be plentiful dimensioned for the airow.
Chemical dosingE.2.4
A high-pressure injector tted between the high-pressure pump outlet and the high-pressure hose may
dose chemicals. You may need to turn down the water pressure by throttling the air motor to achieve
that the injector will work properly. We recommend to disconnect the injector when not in use because
it “steals” pressure.
Cleaning proceduresE.2.5
Hot water, if available, will always give the best result and reduces the need for chemicals. The following procedures are recommended to get the best result when working with detergents:
Apply the detergent with a wide-angle spray. Start at the bottom and move upwards. The spray -
distance should be approximately 40 cm.
Leave the detergent to work approx. 3 minutes, or according to the manufacturer’s instructions. -
However, do not let detergent dry on the surface.
Start cleaning from the bottom and move upward. This prevents water to run down and dilute detergent below. The spraying distance should be 10 – 30 cm.
When cleaning is completed, wash down from the top to prevent stains. Use water generously.-
