Connect the heating coil(s) into the engine cooling
curcuit with flexible rubber hose of the type used on cab heaters
on lorries. Hep20 push fit pipework is recommended for the hot
and cold water connections.

SAFETY: C-WARM OFFERS QUADRUPLE PROTECTION
Marine pressurised water systems are not vented
to atmosphere. C-Warm storage heaters are protected against
excessive internal pressure by a TEMPERATURE AND PRESSURE RELIEF
VALVE pre-set to lift at a pressure well below the test pressure
of the heater (see Specification, page 20), and at a temperature
of 90 deg C.
Water pressure is not in itself dangerous. But
excessive water pressure due to overheating is potentially dangerous,
because it could lead to the sudden release of large amounts
of scalding water and steam into a confined space Overheating
from the engine cooling circuit is not a hazard: the engine
itself would overheat and would have to be shut down before
the water stored in the C-Warm heater could reach boiling point.
Failure of the thermostatic cut-out in an a.c.electric
immersion heater could potentially cause the stored water to
boil, generating excessive pressure. An ordinary pressure relief
valve would eventually lift, but would release scalding water
and steam under pressure. Every C-Warm storage heater is supplied
with a TEMPERATURE AND PRESSURE RELIEF VALVE, so that the water
cannot reach boiling temperature.
To guard against the possible risk of thermostat
failure in the a.c. immersion heater, you are strongly advised
to fit a C-Warm DOUBLE-PROTECTED IMMERSION HEATER, with an additional
high temperature cut-out. The main thermostat resets itself
automatically when the stored water temperature fails below
the cut-in temperature. The high temperature cut-out has to
be reset manually after it has cut off the electric supply.
Hep2O push-fit pipework is recommended for the hot and cold
water connections.
