Warning
The polycarbonate bowl must not be allowed to come into
contact with aggressive chemicals.
Examples of chemicals which attack bowls of polycarbonate
Acetone, benzol, brake fluid, glycerine, some synthetic oil,
chloroform, carbon tetrachloride (and similar solvents), carbon
disulphide, methyl alcohol, perchloroethylene, toluene,
trichloroethylene, xylene (nitrocellulose, thinner), acetic acid.
Important
– Temperature range ±0°C to +50°C.
– Max. working pressure (e) = 16 bar = 1.6 MPa at +50°C with metal
bowl. With polycarbonate bowl max. 16 bar at +25°C and max. 10
bar = 1.0 MPa at +50°C.
Installation
– Remove any foreign matter or impurities from the air line by
blowing it clean with compressed air.
– The filter/regulator must be installed as close as possible to the
equipment which is to be driven by the compressed air.
– If an oil-fog lubricator MIDI DIM 15C or a direct lubricator DOS 15B
is to be installed in the air line, it must be sited after the
filter/regulator.
– The filter/regulator must be installed with the bowl vertical and the
drain valve (45/51) downwards.
– The pressure gauge can be installed as desired on either of the two
connections on the filter/regulator housing. Block the connection
which is not used with the plug supplied.
Note the arrow indicating the flow direction.
– Condensate drained off the filter bowl might be conveyed via a
flexible plastic hose with an inside diameter of 6 mm, which can be
attached to the drain valve (45), instead of the plastic hose (50).
Assembling of bowl guard (55)
– Pull the tab on the lock ring (43) in the arrow direction and turn the
bayonet ring (44) counter-clockwise to stop.
– Hold the bayonet ring so that the bowl remains in bottom position.
Disassemble the lock ring from the bayonet ring. A small
screwdriver (flat edge) could be entered behind the tabs on the lock
ring to ease disassembly.
– Remove the bayonet ring (44) from the plastic bowl (40).
– Assemble the bayonet ring (57) to the bowl guard (56). Enter the
plastic bowl in the bayonet ring. Hold the bayonet ring so that the
bowl and the bowl guard remain in the bottom position.
– Assemble the lock ring (43). The arrow marked tab should fit in the
groove of the bayonet ring.
Assembling of wall mounting bracket (60)
– Remove on both sides of the filter/regulator the small pre-punched
covers in cover (32/33)
– Enter screws (62).
– The bracket (61) could be mounted either with wall screws below
filter/regulator housing or above.
Assembling of two MIDI 15C units
For the assembling an assembly kit (63) should be used.
– Remove the black cover plate on the outlet side of the first unit in
the flow direction (note the flow direction arrows on the housings)
and the cover plate on inlet side of the second unit. The yellow
cover plates should not be removed.
– Put one of the units on a table so the connection surface is
horizontal and turned upwards. Locate the O-ring (64) in the recess
around the flow port. Position the two nuts (67) in corresponding
recesses.
Note – Check that a nut corner meets the shaped nut corner in the
housing.
– Position the other unit so the two units meet surface to surface and
the complete unit forms a straight line with regard to the yellow
front covers.
– Hold the units together and locate the clamps (65). Screw in one of
the screws (66) half-ways. Screw in the other one and tighten to
bottom position. Finally, tighten the first one to bottom position.

Environment care
Wrapping material and used parts should be handled according to
local authorities directions in the country where the product is
installed.
Setting
– Pull the setting knob (2) out and turn it counter-clockwise as far as
it goes.
– Turn on the compressed air supply.
– Set the secondary pressure:
statically (no air flow) or dynamically (while air consuming
equipment is operating).
– Turn the knob clockwise until the wanted secondary pressure is
obtained.
– Setting at lower secondary pressure : turn the knob
counter-clockwise – this causes secondary air relief through the
diaphragm assembly (13) to the atmosphere.
– Relock the setting knob by pressing it in when the pressure setting
has been finally adjusted.
Attendance
The filter/regulator requires a minimum of maintenance apart from
emptying and cleaning. If leakage occurs in consequence of fouling,
the regulating valve (19) and the diaphragm assembly (13) should be
removed for cleaning.
Draining of the filter unit
Type -A
The water is automatically drained off when the float of the drain
valve (51) is lifted to a certain height.
The valve can also be opened manually by turning its knurled
outlet pipe counter-clockwise.
Type -B
The bowl is drained automatically when the pressure in it falls
below 0.2 bar. If the water reaches up to the indicated maximum
level the bowl must be emptied manually by pressing the tabs of
the drain grip (48) together.
Type -C
The water must not reach beyond the indicated maximum level.
Drain off the collected water at regular intervals – appropriately
every day or as found suitable by experience – by pressing the
tabs of the drain grip (48) together.
Type -D
The water must not reach beyond the upper sight glass window.
Drain off the collected water at regular intervals – appropriately
every day or as found suitable by experience – by pressing the
tabs of the drain grip (48) together.
Cleaning the filter unit
The bowl and filter element (27/28) must be cleaned at regular
intervals to avoid loss of efficiency. The filter unit should be washed in
petrol or the like and then blown dry from the inside. The bowl should
be washed with water to which a little detergent has been added.
Dismantling for cleaning of bowl and filter element
Note – There is no need to remove the filter/regulator from the
compressed-air line.
– Vent the air line.
– Pull the tab on the lock ring (43) in the arrow direction and turn the
bayonet ring (44) counter-clockwise to stop.
– Pull down the complete bowl.
– Turn the separator disk (26) 90° counter-clockwise. Pull out the
disk and the filter element (27/28).
– Remove and check the condition of O-ring (30). Replace if
damaged or deformed.
Assembly after the bowl and filter element have been cleaned
– Smear the O-ring (30) with grease and fit it in place.
– Push in the filter element. Position the separator disk and turn it 90°
clockwise.
– Push the bowl and the bayonet ring into the housing with the
bayonet tabs fitting in corresponding recesses. Turn the bayonet
ring clockwise until the arrow marked tab on lock ring (43) snaps
into locked position.
– Check that the bayonet ring is locked by trying to turn it
counter-clockwise.
