Notes:
(a) A pressure control valve regulates main lube oil supply pressure to 241 kPag (35 psig) when
unit is at normal operating temperature.
(b) Prevailing winds must be considered to prevent the lube oil cooler from exhausting into the
engine air inlet system or to take air in from the engine exhaust system. No airflow
backpressure is allowed at the lube oil cooler face.
(c) The maximum total design pressure drop of the off skid oil cooler loop including supply and
return lines shall not exceed 50 psid (345 kpad) at the design flow rate and an oil viscosity of
60 ssu (10.5 centistokes). No check valves are allowed in the oil cooler loop. This is
recommended for all applications (but mandatory for units in cold climates), oil cooler supply,
return and optional vent lines must slope from the oil cooler to the turbine package to
facilitate draining when the unit is not operating.
(d) The heater is mandatory if unit ambient temperature is less than 10°C (50°F).
(e) The lube oil tank immersion heater ensures the lube oil tank temperature remains above
10°C (50°F) for starting in cold temperatures.
(f) The flame arrestor must be installed vertically at the end of the lube tank vent piping.
(g) Start-up strainers must be inspected after 100 hours of operation.
(h) An additional 246 L (65 gal) is required for package filters and piping. Additional oil will also
be required to fill any offskid oil piping and vessels (if applicable).
