Installation

Connect the Fluid Hose (continued)

5.Insert the hose (Y) into the hose ferrule housing

(79).See Fig. 5.

6.Push the hose firmly through the fluid inlet tube

(75)until the o-rings on the hose barbed fitting are seated and the hose bottoms out.

7.Tighten the hose ferrule (77) firmly with a wrench to about 50 in-lb (5.6 NSm). Pull back on the hose to make sure it is secure. If not, disconnect the hose and inspect it for damage. Check the hose connection periodically for signs that the hose is loosening.

CAUTION

If the hose comes loose from the fitting, fluid leakage will occur. Make sure the hose ferrule (77) is tight and that nothing will pull or catch on the hose during operation.

8.Connect the other end of the hose to the isolated fluid supply as instructed in the voltage isolation system manual. See Fig. 6.
