DIMENSIONAL DRAWING
INSTRUCTIONS
This product is to be utilized with clean fresh water, even slightly additivated with normal detergents. For use involving
different or corrosive liquids, contact the PA Technical department. Appropriate filtration should be installed when using
unclean liquids. Choose the gun in line with the data of nominal running (system rated pressure, max flow and max
temperature). In any case, the pressure of the machine should not exceed the permissible pressure rate imprinted on the
gun.
INSTALLATION
This gun was designed to operate with
hot water
(in compliance with the technical specs). Provide the plant generating
hot water
with an equipment limiting the incidental increase of the fluid temperature.
Always
fit a safety valve to protect the delivery conduct when the latter is under pressure.
Choose a suitable nozzle and ad just the valve mounted in the front of the gun, thus obtaining a constant supply and
avoiding unpleasant pressure spike when closing the system.
If the nozzle wears out, the pressure falls. When you install a new nozzle, adjust the system back to the original
pressure.
OPERATIONS
The gun opens and closes a high pressure conduct by means of a piston acting on a seat; the return is controlled by a
spring which releases the trigger
:
ATTENTION: this gun is equipped with a retarder closing device in order to limit
the pressure spikes on the pump and in particular conditions during the starting of the pump a pressure spout
may arise for a few seconds even with the gun closed. In order to prevent injuries or damage see illustrated
chart nr 10.9113.00 attached to the article.
WATER HOSE FEED
By high or very unsteady pressure values on delivery, it is necessary to mount a pressure reducer , both to level the flow
rate on delivery and to protect the system components.
