Cooling system
Max. freshwater capacity
For freshwater capacities see information in chapter
Extra expansion tank
.
Shut-off valves
Volvo Penta recommends that shut-off valves (2, 3)
are installed in the extra cooling circuit on both the
supply and return sides to be shut off for service and
repair or during warm seasons.
Locate the valves as close to the engine as possible
and with a hoose between.
Mounting
Calorifier, cabin heater etc. may be fitted max. 2.5 m
(8') above MIN level of the expansion tank.
Hot water connections
General
A cabin heater and/or a calorifier can be connected
to the freshwater circuit of the engine. When a cabin
heater is installed, it must always have a manual
venting nipple (4) at its highest point. The system is
vented once pressurized.
In large heating systems, a hose thermostat (5)
should be mounted in the line of the hot water cir-
cuit. This ensures that the engine quickly reaches its
operating temperature. Volvo Penta stocks suitable
thermostats.
The illustrations on the following two pages show
where, on each type of engine, coolant can be
tapped off for the hot water circuit.
