Run the compressor untill the crankcase oil is at its stable operating tempera-
ture:
i.1 The lubricating oil pressure difference should be according to Sec-
ción 1.3.6.2, Página 26.
i.2
After the initial run the oil pressure difference should be slightly higher.
Determine the oil pressure difference (difference between the oil pressure
gauge and the suction pressure gauge).
Remove the cap nut of oil pressure regulator if the pressure needs to be re-
-adjusted.
Turn the slotted pin with a screwdriver clockwise or counter clockwise for a
higher or lower oil pressure respectively, until the required lubricating oil pres-
sure difference has been achieved.
Replace cap nut and sealing ring.
El regulador de presión del aceite se ajusta durante el funcionamiento, pero es posible que este ajuste se
deba corregir durante el funcionamiento inicial y también si el valor es <1,5 o >2,5 bar. El procedimiento
de reajuste aparece en la sección Reajuste del regulador de presión del aceite.
