F. Installation of the PRV to HPV Tube Assembly
(1) Remove the protective covers from the hose tube assembly (45), the fittings on the valves (40) and (60) and the tube assembly (20).
CAUTION : APPLY ONLY A THIN LAYER OF (CP5063) SILICON LUBRICANT TO
_______ THE THREADS OF THE HOSE TUBE ASSEMBLY COUPLING NUTS AND FITTING ON THE VALVES, AND REMOVE UNWANTED LUBRICANT. KEEP LUBRICANT FROM GOING INTO THE HOSE TUBE ASSEMBLY AND VALVES. IF TOO MUCH LUBRICANT IS USED, THEN LUBRICANT MAY CLOG THE HOSE TUBE ASSEMBLY AND ENTER THE VALVES AND DAMAGE THOSE COMPONENTS.
(2) Lubricate the threads of the coupling nuts and the fittings with silicon lubricant (Material No. CP5063).
