Weekly maintenance
Check the installation weekly for:
•
Leaks and loose parts
• Insulation defects; visually inspect for ageing and
damage
•
Soiling of the supply tank
•
Operation of the valves, spray guns, pulsation
dampeners, electrical cabinet
•
Ageing of the hose pack
• Cleaning of the motor cooling vanes [17] .
Maintenance of the Blocksat satellite
• Regularly check the chemical suction hose and the
injector for contamination
[18] . Contamination influences
the operation of the Blocksat. If the venturi does not let
enough litres through (when foaming approx. 8.0 litres of
water per minute must flow through the venturi and when disinfecting approx. 5.5
litres per minute), it probably has an internal blockage. Stop the pump and shut off
the water supply to the installation. Set the lever to the foam position (white) and
depressurise the hose and any mounted reel by operating the pistol until no more
liquid comes out of it. Use a screwdriver to remove the injector(s) which is/are
screwed to the side. The injector(s) can now be removed from the block and cleaned.
Check before reassembly that the O-rings are undamaged and free from dirt; screw
the injector all the way in until it stops.
• Regularly check the non-return valves [19] for
operation. If they are not functioning correctly, there is
a risk that water will enter the air supply network.
•
Water and/or compressed air flowing out of the overflow
valve
[21] is an indication that the non-return valve [20] is broken. Replace of repair
it.
•
If the venturi lets sufficient water through, but does not draw any agent, the
restriction in the suction sleeve must be checked for blockage. Removal: unscrew the
