To install the cooling jacket
1. Install the O-rings in the grooves of the cooling jacket.
2. Lubricate the O-rings with soapy water or a light oil to
ease assembly of the cooling jacket onto the cylinder.
3. Slide the cooling jacket onto the cylinder using a twisting
motion.
Note
It is important that the cooling jacket be installed with the locking
set screw away from the cylinder cap.
CAUTION
Be careful not to damage the O-rings when pushing them over
the threads of the cylinder.
Reassembling the pump
1. Place the cylinder/cooling jacket assembly over the piston
and push rod assembly.
2. Screw the assembly into the cylinder housing until the cylinder
no longer turns. This indicates that it is snug against
the piston.
3. Unscrew the cylinder a minimum of 1 2 turn.
4. Line the inlet and outlet cylinder cap ports up as you had
them before. Turn the cooling jacket ports to the desired
location and lock the cooling jacket to the cylinder by tightening
the cooling jacket lock set screw.
5. Lock the cylinder by tightening the cylinder locking screw.
6. Replace the front cover and adjust both covers so they are
flush with the cylinder housing.
7. Reinstall tubing.
8. Reconnect the pump pressure transducer cable.
Note
Anytime you adjust fittings on the cylinder cap you should
re-zero your pump’s pressure transducer. See section 3.5.8.
The pump’s pressure transducer is a very sensitive strain gage
which can be offset as much as 17.2 bar by tightening fittings.
