DISMANTLING AND ASSEMBLING THE FILTER COMPONENTS
Opening the filter and disassembling its inner components is necessary for changing screens, periodic maintenance
and repairs.
Prior to opening the filter, it is recommended to initiate a flushing cycle by pressing the "TEST" push button.
Before beginning any maintenance procedure, carefully read the safety instructions in chapter 2 of this document
and make sure that all the workers at the filtration site are fully aware of and comply with, these and any other
local safety instructions.
Dismantling:
1.
Disconnect the electrical power and lock the main switch.
2.
Close off the water and drain the filter housing.
3.
Disconnect the compressed air supply, lock the main switch and release the residual pressure.
4.
Unscrew the bolts of the exhaust valve, disconnect the air pressure tubes and remove the valve.
5.
Unscrew bolts (26) and remove the drive unit (25). Put the drive unit on a dry and protected surface near
the filter. If the electric cable is not long enough, disconnect it from the motor.
6.
Pull out the split pin (19) from the connecting pin (18) then pull out the connecting pin. If the connecting
pin is not facing one of the shaft housing windows, turn the drive shaft (3 on page 23) a little. Use 17mm
or 11/16 spanners.
7.
Turn the drive shaft (3 on page 23) counter clockwise so that it will be separated from the suction scanner
shaft (2 on page 24).
8.
Unscrew bolts (10 on page 23) and remove the limit switches sling (9 on page 23) without disconnecting
and changing the limit switches position.
9.
Unscrew bolts (20) connecting the shaft housing (17) to the filter lid (12).
10.
Pull up the shaft housing. Put it near the filter, make sure not to damage the limit switches electric wires.
If necessary, disconnect the wires from the connecting box (48). (Do not forget to mark all wires for
proper reconnections).
11.
Unscrew the housing bolts (13) and pull the lid using a crane or other lifting device, make sure that it is
located exactly above the lid center. Make sure that the lifting device is a standard device, operated by
an authorized operator in accordance to all relevant safety standards. Never lift any filter component
above people or equipment.
Note: the lid must be lifted vertically while maintaining its horizontal position; this prevents damage to
the suction scanner and the upper bearing seals.
12.
Pull the scanner (8) and the screen (7) (including screen seals 6); make sure that extracting the screen
is done according to the following description.
Extracting the Screen
Before handling the screen, carefully read the safety instructions chapter of this document and make sure that all
the workers at the filtration site are fully aware of and comply with, these and any other local safety instructions.
Please note that the screen is heavy and in order to avoid damage and injury it should be lifted only with Amiad’s
standard Extractor and a standard lifting device operated by an authorized operator.
1.
Clean and dry the rubber pads on the Extractor
