Installation
Tank Installation
•
Place the tank in a position where you have access to connections and inspection points. Ensure that there is enough space to remove and
replace the fi lters.
(NB: Ensure room for access to the oil fi lling point.)
•
Place the tank high enough to get the oil level above the hydraulic pump. The system requires overpressure/gravity feed in the pump feed lines.
•
Secure the tank assembly properly.
•
Ground the tank electrically to the boat’s bonding system.
•
Ensure that the tank and other components are thoroughly clean before you start the installation of fi ttings and hoses. Also, make sure that the
fi ttings and hoses are thoroughly clean (avoid ingress of dirt, water and other contamination).
•
Ensure to plan and install the cooling system in accordance with the Hydraulic system manual.
Pump Installation
•
Check that the power source drive direction is in accordance with pump rotation!
•
Pump direction is decided as described in Hydraulic system manual, facing the pump shaft, i.e the pump direction will be the opposite of engine /
PTO /generator. (NB: Please see (PTO) pump nameplate L=CCW and R=CW)
•
Ensure that the power source and connection point can handle the torque and load from the hydraulic pump.
•
As soon as the pump is connected to the power source, it is very important NOT to run the power source before the installation is complete and
the pump is pre-fi lled with hydraulic oil.
Hydraulic Hoses
Each thruster system is calculated and correctly set up individually by Sleipner. Please see the unique system drawings in the provided system
manual for hose/tube/fi ttings dimensions. Hoses and fi ttings must be installed by trained professionals only. Make sure to clean the hoses internally
before assembly, all hoses MUST be cleaned with jet pellets or flushed before they are fi tted
(NB: Cleanliness requirement according to: Required
cleanliness class ISO 4406-1999 21/19/16)
.
To ensure easy and trouble-free connection, apply a small amount of oil to threads and mating faces before connecting. Different fi ttings will require
different tightening torque to avoid leakage. If in doubt, please contact a skilled professional to get the best results. It may be required to check and
re-tighten all hose connections after start-up and sea trial.
Oil fi lling
Before fi lling the tank, prime the pump(s) through their upper drain port. Use only oil quality as specifi ed. Fill the tank with correct hydraulic oil through
the fi ller/breather unit. It is recommended to use a fi ller trolley with fi lter (10 micron). Use only new mineral based hydraulic oil, ISO VG46. Use ISO
VG32 oil on systems without stabilizers when the vessel will operate in arctic conditions.
Oil to be according to ISO 11158 Class HV/DIN 51524 Part 3 Class HVLP. The oil level in the tank should be approximately 3/4 full, or at the middle of
the upper indicator of the sight glass. Because vessels heel and the fact that we have an air breathing fi lter in the oil fi ller cap, avoid higher oil level
than what the sight glass can indicate. Always check oil level and refi ll during start-up and air purging.
