Operating and
service instructions

General Information

Dear Valeo Customer,
We assume that the operation and function of your new heater will have been explained to

you properly and to your complete satisfaction by the installing workshop / service outlet.
This owner's handbook is designed to give you a brief summary of how to use the Thermo
Plus 230/300/350 heaters.

The heater operation is unlimited without a change of the CO adjustment up to an altitude
of 1500 m above MSL and up to 2000 m above MSL if that is a short stay in such conditions
(pass crossing, break).

In case of a permanent heater operation above 1500m the CO setting must be readjusted
by Valeo trained personnel, due to a change of the exhaust gas values depending on
environmental conditions.

Service and safety instructions

For the heater exist type approvals according to ECE Regulations R122 (Heater) and
R10 (EMC).

The heaters must be installed as described in the attached installation instructions. The
installation must be checked pursuant to the statutory regulations governing installation
work. Further details are given in the installation instructions.

The year in which the heater is used for the first time must be permanently marked on the
heater's model plate by removing the inapplicable year numbers.

Ensure that the existing shut-off devices in the fuel return line are open prior to starting the
heater.

When the coolant used in the vehicle's engine is renewed, after bleeding the vehicle's
cooling system, pay attention to bleeding the heater carefully. Top up the coolant as
described in the instructions supplied by the vehicle manufacturer.

Check the openings of the combustion air intake and exhaust outlet and clean them if
necessary.

WARNING!

Risk of fire, explosion, poisoning

and asphyxiation!

The heater must not be operated:

n at filling stations and other refueling points.
n if the heater or its exhaust outlet is in locations where inflammable vapors or dust may

form (e.g. close to fuel, plastic, coal, wood dust or cereal storage facilities).

n if the heater or its exhaust outlet is located close to inflammable materials for example

dry grass and leaves, cartons, paper etc.

n in enclosed areas (e.g. garages, hall without a suck off facility), not even if the pre-

selection timer or Tele Start is used.

n if the exhaust outlet of the heater is partial or fully obstructed (e.g. by soil or snow, as it

may occur while move the vehicle backwards).

The heater must:

n be shut down and the fuse shall be removed in the event of extensive smoke

development, unusual combustion noises or fuel odors. The heater must not be used
again until personnel trained by Spheros have examined it.

ATTENTION:

The heater must not:

n be exposed to temperatures exceeding 110°C (storage temperature). Exceeding this

temperature may result in permanent damages.

n be operated without at least 30% of a brand name anti-freeze in the heating system

water. An up-to-date list of anti-freeze approved by Valeo can be found on the Valeo
website.

The heater must:

n with a diesel fuel approved by Valeo in accordance with DIN EN 590 (see TI's Fuels on

the Valeo website for more information) and the rated voltage shown on the model
plate.

n be operated at least once per month for 10 minutes when the engine is cold.

At the latest when the cold weather season starts the heater must be inspected by an
expert.

Liability claims

Failure to follow the installation instructions and the notes contained therein will lead to
all liability being refused by Valeo. The same applies if repairs are carried out incorrectly
or with the use of parts other than genuine spare parts.
This will result in the expiry of the ECE type approval of the heater and thus the general
operating permit.

Liability claims can only be made if the claimant has verifiably considered all the servicing
and safety instructions.
