Use / Version

The fully electrical water heater Thermo DC operates independently of 
the vehicle engine and is connected to the  vehicle’s cooling and 
electrical systems.

The electrical heater can be used in a depot for pre-heating purposes. 
For this it is connected stably to the depot 690 VDC power supply. 
Further more the heater also can be used in electric driven buses or 
hybrid buses where a 690 VDC power supply is provided, in association 
with the vehicle‘s own heating system:

– to heat the passenger cabin, and
– for pre-heating.

Deviating installation / use must be agreed in advance with the Valeo 
product support.

The heaters are approved for horizontal installation only (see Figure 10).

The heater Thermo DC is approved for heating the diesel engine 
and the passenger cabin of buses, but not for use in vehicles 
subjected to the Directive 94/55/EC (ADR, TRS).

General Information / Safety

Check the information given on the rating plate of your heater / in the 
technical data and compare this with your mains voltage!

In addition to the statutory regulations the specific connection conditions 
of local electricity companies are to be observed.

No alterations to the electrical installation may be undertaken.

The installation and commissioning may only be carried out by a quali-
fied electrician.

Only have any work on the appliance carried out by a specialist 
company or a qualified person.

The installation instructions are to be considered.

 

Under no circumstances touch the heat exchanger and the water 
hoses during operation, in particular when they are overheated due 
to lack of water.

Ensure an adequate distance to all surrounding parts and a sufficient 
ventilation during installation.
Alternately use fire resistant materials or heat shields (see Statutory 
Regulations governing installation, para. 5.3.2.2).

Danger to life and health!

Warning!

Hot surfaces!
