INTRODUCTION
1.1 GENERAL
This manual applies to the installation of Mastervolt
Whisper 3,5 generating set in vehicles.
Special attention has to be given to the
chapter on safety that is in the users
manual.
A warning symbol draws attention to
warnings and instructions or procedures
which, if not strictly observed, may result in
damage or destruction of equipment,
severe personal injury or loss of life.
This warning symbol refers to electric
danger and draws attention to special
warnings, instructions or procedures
which, if not strictly observed, may result in
electrical shock which will result in severe
personal injury or loss of life.

GENERATING SETS FOR VEHICLES
1.2.1
Marine and mobile generators
Whisper Generators originate from the marine sector. But
there are also specially designed Whispers available for
mobile applications, suitable for supplying power on
board of vehicles to use professional apparatus and
equipment, strong lightning and air conditioning etc.
The cooling system and exhaust system on vehicles is
completely different from standard marine systems.
Standard marine generators are cooled by seawater that
nowhere exceeds 30° Celsius and is seldom warmer
than 20° Celsius in the northern territories. Cold
seawater is pumped through the alternator, through the
heat exchanger and is injected in the exhaust. The
exhaust gasses are therefore cooled and rubber exhaust
hose can be used.
On vehicles the engine and alternator are individually
cooled by radiator with an electric (12V/24V or 230V)
driven fan. The radiators can be fitted below, on top or in
the side of the vehicle.
The exhaust is of the dry type and includes a stainless
flexible bellow and high quality mufflers.
Never use rubber exhaust hose, neither
fibreglass nor plastic exhaust parts in a dry
exhaust system as applied on vehicles.
1.2.2
Why two radiators:
The Whisper 3,5 engine is cooled by oil. The optimal
engine operating temperature is 87° up to 92° Celsius.
The radiator cools the temperature of the oil in the engine
only 5° to 12° down. The returning “cold” oil therefore has
a minimum temperature of 75° Celsius.
