Hydmaster 40
THE USE OF THE MACHINE
Before beginning the work check the channel network with Lifa DuctTruck
(accessory). There may be air volume controllers, noise silencers, fire dampers etc.
that can be damaged during the work.
In large rectangular ducts, there might be supporter poles inside the duct. Use extra
care, when dealing with ducts equipped with supporters. When cleaning large
rectangular or round ducts the use of Lifa Centring device (Accessory) is highly
recommended.
Choose a right sized brush (depending in the size of the duct). Make sure that the
brush isn’t too small or big for the duct that is going to be cleaned. Nylon grease
/Tynex brushes are meant for cleaning the grease ducts. The combination brushes
are meant to use only in grease duct cleaning
Adjust the rotating speed of the brush. Note that when cleaning “soft” ducts the
rotating speed should be much lower than in normal ducts. Too fast rotation speed
may damage the ventilation duct channel. Only softest brushes may be used.
Make sure that the working area is cleared and there are no extra personnel.
Ensure that all the employees performing the work have adequate protective
equipment.
Make sure that there is enough low pressure in the channel network and that Lifa
HepaClean or AirClean is installed correctly.
Connect the machine in to an electrical network with grounding.
Place the brush inside the ventilation duct that is going to be cleaned.
Connect the machine into a current from the protective switch for motor.
When the shaft is being pushed to the duct avoid sharp angles and screws etc.
which can damage the shaft, especially sharp edges of duct opening.
When the operator who is feeding the shaft in to the duct gives a permission to start
the machine, the machine can be started.
The brush can be rotated to clockwise and counter clockwise. Use both rotating
directions in order to make sure the best possible cleaning result. In rectangular
ducts it may be required to clean one side first (with rotating the brush in one
direction only) and after that another side.
Feed the shaft steadily (slowly) in to the duct without excessive force. The use of
excessive force may harm the duct, machine or brush and influence to the cleaning
result.
