SYMPTOM

LIKELY CAUSE

POSSIBLE SOLUTION

Presence of oil on the discharge of the 

safety valve.

Opening of the valve due to failure of 

the protective devices to operate.

Check that the high pressure switches 

are working and, if necessary, replace 

them.

The valve must be replaced.

Opening of the valve due to overtem-

perature.

Replace the valve and restore the 

charge.
