Page 37025 Instruction Manual (Rev. 2)Particular care has been taken in finishing the cylinder inside surface (diamond lapping),to minimize the O-ring wear. The piston fits snugly inside the cylinder and is made airtightby two conveniently spaced O-rings.The slide valve is placed perpendicular to the cylinder to minimize dead space, and isoperated by a crank-link mechanism (4-8, see Figure 1 “Linkage”).The valve is made airtight by an exact fit between the seat and the spindle.2.3 Pump FrameThe backbone of the instrument is a heavy gauge (10 mm) aluminium plate to which allmechanisms are fastened.Figure 1 “Linkage” illustrates the external fittings, namely the valve block (17) the variablestroke disk (7) and its control knob (14).The transformer, the geared motor and the electronic printed circuit board are fastened tothe other side of the plate (see paragraph 7.2-Access to the Inside of the Instrument).The plate is fastened to the left wall (the side of the air ports) by two M4 oval-headscrews. The combination wall/plate forms a solid “T” structure, which glides out from therails of an all welded 4-sided cabinet, by simply removing the six M4 screws indicated.This impeccable design makes all internal and external components totally accessible ina matter of 30 seconds.3 INSTALLATION3.1 Unpacking & Preliminary CheckCheck the contents of the shipment for completeness, packing list to hand, and visuallyinspect the instrument as soon you take it out of the packaging.
