OPERATION INSTRUCTION
The motor complies with the provisions of the Directive 94/9/EC (Atex 95a).
The impeller and casing are made of materials with a reduced risk of generating heat or sparks, if
there should be an operational problem.
Store fan in its original packing at a dry place and protect it against the weather. If stored for a long
period, check the impeller bearings move freely by turning it by hand.
Please ensure no foreign matter e.g. paint particles get into the airflow and causes damage to the
impeller.
Use protective grilles to prevent foreign particles from getting into the suction and exhaust holes.
Do not deform the fans by improper fastening.
Be careful not to damage the casing or any moving parts.
The gap between impeller and casing is properly set when the fan was manufactured.
When working at the fan (like assembly, operation, maintenance and repair) ensure gap is the same
all the way around with a minimum distance between these parts of at least 1% of the greatest contact
diameter.
Prior to operation, blow out the air hose and connect it to the plug cock.
The power turbine must not be lubricated. Do not fill any oil in the hose (do not use line oilers).
Repair of the fan should only be performed by qualified and skilled workers. Instructions and
directives have to be kept.
Bearing clearance too large?
Lubricant on the bearing?
Unusual
noise?
The grease packed in the bearings is sufficient to at least approx. 5000 working hours. After
this time dismantle, clean and fill 1/3 to 1/2 with high quality antifriction grease. Replace damaged
bearings. Ensure fans are mounted by competent, trained personnel.
