If you encounter any unexpected noise or rough motor operation, disconnect the equipment from the power
supply and check its state. Repairs shall be given to authorized IN-ECO service centers.
6.2 M
AINTENANCE
Disconnect the equipment from the power supply to avoid electric shock. Ensure the equipment will not re-
peatedly start upon reconnection to the power supply. Do not perform maintenance work if the equipment is
heated up to operating temperature.
Check and replace the following regularly:
>
air filter in the intervals specified by the supplier,
>
bearings* in the equipment.
*) The minimum service life of bearings is 15,000 operating hours, providing the operating conditions are
respected. The replacement of bearings shall be given to authorized IN-ECO service centers. Keep the report
from the bearings replacement.
When disconnecting the equipment from the pipes, close the suction and discharge branch with a plastic co-
ver, which was supplied or in some other manner. During maintenance, prevent any objects from entering the
blower or pipes.
After maintenance, or repair, prior to start-up, proceed according to the instructions in section 5.1 Start-up.
6.3 S
TORAGE
Keep the INW blowers/pumps in a dry environment with normal air humidity. For a relative humidity of 80% or
higher, store in a closed package with a drying agent.
7 S
ERVICE
Repairs shall only be carried out by an authorized IN-ECO service center during the warranty period. All war-
ranty rights are forfeited if the equipment is tampered with during the warranty period. Have an authorized IN-
ECO service center service INW ring blowers / vacuum pumps after the warranty has expired.
8 Accessories
Use original accessories with INW blowers/pumps with side channel. Contact the authorized IN-ECO service
center for the specifications and supplies of accessories (for example: air filters, safety valves, manometers,
backflow valves, flowmeters).
8.1 A
IR FILTER
The air filter should be installed as close to the suction branch as possible to protect the equipment against
solid objects, dust, cellulose, etc. Do not start the equipment without an air filter. The filter should not let parti-
cles larger than 40 μm through.
Use a filter with sufficient capacity so the pressure loss is adequate.
Original air filter
The air filter (filtration insert) must be cleaned no later than after 250 operating hours and the filtration insert replaced no
later than after 3,000 operating hours. The authorized IN-ECO service center will supply the filtration insert.
Removal:
a) blower filter / unscrew the wing nut. Remove the protective cover and take out the filtration insert.
b) pump filter / release the closing pins of the filter lid. Remove the filter lid and take out the filtration insert.
Clean the filtration insert (blow and manually dust) and replace if necessary.
Assembly: in reverse order.
The filtration insert of the air filter must be cleaned or replaced more frequently depending on the level of medium impuri-
ty. Performance becomes impaired with insufficient maintenance of the air filter and with it the service lift is shortened.
8.2 S
AFETY VALVE
Install a safety valve to prevent from overloading the equipment and subsequently shortening its service life.
The safety valve must be configured for the maximum working pressure. This way the equipment will be pro-
