Stopping Operation - bar Comet AX Series Assembly, Operation And Maintenance Instructions

CAUTION
• To permit fast pump priming, proceed as indicated at point a) every time the pump has to be primed again.
• During the first hours of operation, it is best to check the oil level and, if necessary, top up the level, following
the instructions in the
• In the case of models with built-in regulation valve (pumps marked by K preceded by a dash and
series AX and BX) and of all those applications where the pressure unloader/regulation valve bypass is
connected to pump suction, do not keep the delivery line closed for more than five minutes (e.g., with
spray gun closed), so as to prevent the water recirculating in the head from overheating with consequent
seal damage.
• Do not operate the pump if it is too noisy and/or water or oil is dripping from it: in this case have it checked
by a Skilled Technician.
WARNING
• Follow the instructions contained in the manual of the machine in which the pump is integrated.
• The pump has been designed to be used with the detergents recommended by the Manufacturer. The use of
different detergents or chemical products could cause safety problems. In particular, never suck up liquids
containing solvents, petrol, thinners, acetone and fuel oils, because the nebulized product is highly inflammable,
explosive and toxic.
• Carefully read the instructions and safety precautions on the detergent packs, so as to be able to implement
the necessary measures in case of hazards threatening individuals and the environment. In particular, never
exceed the maximum recommended concentrations and only prepare the quantity of product needed to prevent
it spreading on the ground and in waters.
• Store the detergents in a safe place out of reach of children.
• In case of contact with the eyes, wash immediately with water. In case of ingestion, do not provoke vomiting:
immediately contact a doctor and show him/her the detergent pack. Avoid inhaling any produced gases.
The detergent suction option is standard only for a number of models of the LW, ZW, AX and BX series.
To learn how to use the detergent, refer to the detergent pack label, with special attention to doses.
Perform the steps relating to operation with detergent shown in the manual of the machine integrating
the pump; unless otherwise indicated, in relation to the pump, the following should be remembered.
a) Reduce the pressure of the pump to below 30 bar/435 psi (e.g., in the case of a high pressure cleaner, by
moving the nozzle head to low-pressure position).
b) If the detergent suction adjustment option is provided, adjust the knob (16): turn it clockwise to reduce the
flow of detergent suctioned and anticlockwise to increase such flow.
CAUTION
• To prevent scale and/or deposits, after using with detergent, it is best to wash the flow ducts by sucking up
some water.
By closing the delivery line, the pump switches to bypass operation and remains in this condition until the
delivery line is opened again.
CAUTION
• Never leave the pump in bypass for more than five minutes, and avoid the water re-circulating in the pump
head from overheating, with consequent damage to seals.
