1. Carefully pull or push out the appliance and verify that the
Restraining Cable limits the travel of the appliance and
prevents the application of any pull force or bending stress
on the agent Distribution Hose or hose-to-pipe connections.
2. Check the Restraining Cable to verify it is not frayed and is
securely fastened to the appliance and the wall or restrain-
ing location.
3. Check the hose and hose fittings and verify that the hose
remains in a vertical natural loop with no noticeable fatigue
at hose end couplings, no hose twists, no hose kinking or
sharp bends. See Figure 4-31.

ing, tears, or wear. If any of these signs are observed,
replace the hose.

check the hose and hose fittings to verify that the hose does
not have sharp bends, and is not kinked, twisted, or caught
on anything behind the appliance. If any of these conditions
exist, the hose and/or hose connections will require installa-
tion modifications.
6. With the appliance in its normal operating position, check
the hose bend to make certain the bend is not less than a
3 in. (76 mm) bend radius (6 in. (152 mm) diameter). If less,
replace hose.

location. Failure to do so may result in undue stress and
fatigue of the hose and hose connections.
