Hot water connections
Hot
water connections may be made to the thermostat
housing (outlet) and the circulation pump (inlet). The
unions supplied by Volvo Penta are intended for hoses
with and inner diameter of 16 mm (5/8”).
Install the auxiliary hot water circuit so that its highest
point is at least 50 mm (2") (A) lower than the fluid level
in the expansion tank. If this is not possible, a separate
expansion tank must be installed.
Shut-off valves
Volvo Penta recommends that shut-off valves be
installed on both the inlet and outlet sides of the auxil-
iary circuit. Locate the valves as close to the engine as
possible.
