INSTALLING THE HYDRAULIC OIL COOLER
1. Position the oil cooler so it is protected from impact and excessive
vibration. The cooler must be placed in series in the return to tank
line and as close to the reservoir as possible.
2. Bolt the cooler onto the frame or appliance. Leave at least 9 in. of
clearance in the front and rear of the oil cooler to allow for air flow
and to decrease the noise it may create.
3. Fill the cooler with hydraulic oil prior to attaching the hoses.
4. Either port on the oil cooler can be used as the inlet or outlet.
4.1 Add a thread sealant to the fittings to prevent leaks.
4.2 Use two wrenches when connecting the hoses to the cooler,
one on the cooler inlet/outlet port and one on the hose
fitting. Apply equal force on both wrenches to prevent the
oil cooler body from bending or twisting when the hose
is tightened.
5. Wire the fan to a 12 volt power source. Incorporate both an ON/
OFF switch and a fuse as listed in the Recommended Fuse Size
(see Specifications).
6. Check all fittings to make sure they are tight before starting the
hydraulic system.
7. Run the hydraulic system for 1 to 2 minutes then shut off and top
up the reservoir with oil if necessary.
8. install a bypass circuit to avoid damaging the oil cooler if
the ambient temperature will be below 40°F (4.4°C). At low
temperatures, the oil will thicken and could cause a rupture due
to backpressure when the oil is forced through the cooler’s small
passages. Please install the bypass circuit according to Figure 3.
