Hydraulic Installation
PTO pump pre-startup
•
Fill the hydraulic tank. (ISO VG 46 (by ISO 3448). Or, 32 for Arctic climate.) See detailed specifi cations.
•
Remove the pump drain blank or hose from pump to ensure the oil has reached pump)
•
Re-fi t drain blank or hose in PTO pump port, or at the gauge on accumulator block.
•
PTO1: Start engine1 and watch pressure gauge for standby pressure of 10-30 bar. (Monitor oil level)
(NB: Gauge at PVG valves for th stabilizer system. For stabilizer only pressure reading on system status page in the stabilizer control panel.)
•
PTO2: Start engine2 and watch pressure gauge for standby pressure of 10-30 bar. (Monitor oil level)
(NB: If no pressure, confi rm pump rotation.)
•
Check for leaks between tank and pump that is running
•
Shut down engine(s) and check the oil level in the tank. Refi ll if required. (Refi ll oil only after the accumulator tank is de-pressurized to avoid
flooding the tank later on.)
PTO pump pressure adjustment
Most stabilizer systems come with pre-set PTO-pump(s) from Sleipner. The pump has a tag on the drive shaft telling actual pressure setting if this tag
is not present, or other settings are required the pump pressure must be checked and adjusted if necessary.
(NB: System pressure will always be directly related to the actual system load at the time. Lack of system pressure is more often caused by open
bleed/bypass/dump valve or other system related problems than incorrect pump setting.)
When the above issues are excluded and pump pressure is confi rmed incorrect contact Side-Power for pump adjustment instructions. Please have
system serial number and pump model data available for correct instructions.

IMPORTANT
Before fi lling the system oil tank, prime the pump(s) through their upper drain port. Stabilizer system must not be activated. Check pump
feed line from the tank (Dimension/routing) for good gravity feed.

IMPORTANT
Electric operated decouple valve (coil nut) to be re-torqued to 6.8-9.5 Nm (5-7
Ft-lbs) Over torque of the coil nut will damage the valve function.

WARNING
If the valve is unlocked and opened be aware of unexpected movement of fins and
cylinders. Especially if the boat is afloat !
