• Before the heater is installed again in another vehicle, rinse
the heater parts carrying water with clear water.
• When carrying out electric welding on the vehicle, the
plus pole cable at the battery should be disconnected and
placed at ground to protect the controller.
• The heater must not be operated where there is a risk of
an accumulation of flammable vapours or dust, for example
close to:
– fuel depot
– coal depot
– wood depot
– grain depots etc.
• The heater must be switched off when refuelling.
• When the heater is mounted in a safety housing etc., the
installation compartment of the heater is not a stowage
compartment and must be kept clear.
In particular fuel canisters, oil cans, spray cans, gas
cartridges, fire extinguishers, cleaning rags, items of
clothing, paper etc. must not be stored or transported on or
next to the heater.
• Defect fuses must only be replaced by fuses with the
prescribed rating.
• If fuel leaks from the heater fuel system, arrange for the
damage to be repaired immediately by a JE service partner.
• When topping up the coolant, only use the coolant
permitted by the vehicle manufacturer, see the vehicle
operating manual. Any blending with unpermitted coolant
can cause damage to the engine and heater.
• After-running of the heater must not be interrupted
prematurely e.g. by pressing the battery disconnecting
switch, apart from in the case of an emergency stop.
The fitting of a diesel heater in a petrol engine boat is
permitted with the following provisios:
• The heater must not be mounted in the engine
compartment.
• RCD 94/25EC or ISO 100088:2001 are followed.
• The combustion air pipe must be taken from a vented to
atmosphere area.
• The exhaust system must be routed as recommended in
our Marine Installation Manual (Section 5).
• Heating intake air must be taken from a clean dry
environment.
Accident prevention
General accident prevention regulations and the corresponding
workshop and operation safety instructions are to be observed.
Please read carefully the following instructions, these have
been compiled to assist you with every aspect of installing your
heater. Special attention is required to the Safety or Caution
areas, which are found at the end of each section.
To ensure maximum performance from your heater and for your
own safety, please adhere to the following instructions closely,
being aware that in the unlikely event of a heater failure during
the warranty period, that warranty may be rejected if the heater
is not installed in accordance with these instructions.
Additional operational, technical and safety information,
specific to the model of heater you are installing, are provided
in the heater technical description and operating instructions
manuals that are included within the heater packaging. Please
ensure you have this for reference before and during your
installation.
When installing the heater, for your own safety, please use
all necessary personal protection/safety equipment where
required.
Before you begin, we advise that you take some time to plan
the installation.
Planning your installation
Where and how you install your system will depend on various
limitations of both your boat design and construction as well
as the technical specification of the heater. Because of this we
have endeavoured to give helpful advice within the different
sections of this manual, we advise that each section is read
fully before commencing the installation.
As a general guide before you begin, be aware of the location
of the boat’s fuel and water tanks, the batteries and any cold
box, fridge or cooker that may prohibit the routing of the water
hoses or affect the installation.
Before installing the heater into the boat, ensure that in doing
so you are not infringing upon, or contravening any legal
requirements of the boats use or construction. For instance,
if the boat is to be used for hire purposes, it may require
additional systems or warning labels to be installed, which may
not be mentioned in this manual. Similarly, advice from the
boat manufacturer may be required if you plan to cut through
bulkheads that may be structurally important to the boat design.
Regulations that could affect the installation of the heater may
be different in each country, so please check.
