Water cooling
When attaching the water cooling unit to the
TURBOVAC
35 LS, 35 LS2 and
50, remove the pump foot and then bolt the cooling unit to the bottom of the
pump. The mounting bolts are provided with the water cooling unit.
Connect the coolant hoses to the hose nipples and secure with hose clamps.
If the coolant flow is turned on and off by means of a solenoid valve, make
the electrical connection in such a way that coolant flow will be started and
stopped together with the pump itself.
