Howden wrv163 lube oil pressure

[Tycho]

Thanks RANGER1. The oil in use is LULUBE 1220. I was looking over that manual you posted. Section 6 troubleshooting 6-1 'Low Run Oil Pressure" states "Oil pressure is manifold pressure minus the suction pressure". Thought it was Manifold pressure minus Discharge Pressure for screws?

I think that must be a "typo", on the WRV range it's manifold pressure minus discharge pressure like you say

Ranger, i took the liberty of adding that manual to my shared folder with Howden manuals
