Changing Piston and Cylinder
This Ventilator is furnished with a 5 cc piston and cylinder installed. A 30 cc cylinder and
piston is also supplied for users that require larger tidal volumes.
Note: It is extremely important when changing piston and cylinders that they
be aligned to be concentric and in line with the piston shaft.
The cylinder is fastened to the 4 port vertical slide valve by means of two screws located
between the “room air inlet” port and the “to animal” port on the front of the slide valve.
For ease of mounting, there is an alignment bracket located below the valve body. When re-
attaching a valve to the 683 Ventilator, the cut-out in the valve should sit square and parallel
with the corner of the alignment bracket. This should ensure that the valve and piston shaft
are in line with each other.
The vertical slide valve is fastened to the black 1/4" aluminum sub base by four screws locat-
ed on the opposite side from the printed label. After mounting a valve; if coupling does not
engage piston shaft, loosen cylinder mounting screws and adjust cylinder position until piston
shaft enters coupling with ease.
