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 N
m). 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.
