up to 25°C engine oil SAE 10-40
over 25°C and continuous duty:
gear oil SAE 80W-90
quantity 0,36 liter = mid sight glass
initial oil change
after 50 hours, then
Every 300 operating hours at the latest or once a
year. Earlier when the oil gets a white color by
condensation water.
Service pressure regulation valve.
Maintenance is limited to cleaning and silicone
grease lubrication after 12-24 months.
The O-ring (5) has only to be changed in case of
leakage.
To take the pressure pin out of the valve body,
unscrew the adjusting knob (1). Then take off
the spring (2) with pressure disk (3). Now you
see the pressure (4) pin with a M3 tapped hole
and pull it out by screwing in a M3 screw.
Note: The drinking water production changes according to the salinity, the temperature of the
seawater and the age of the R.O. membrane. The data regarding the fresh water production apply to a
salinity of 35 grams/liter at a temperature of 25ºCelsius (77°Fahrenheit) at the new membrane.
A discrepancy up to 10% +/- is within the usual range. At current consumption, discrepancies of up to
5% +, especially in the first 50 hours of operation, are usual.
