Radiator Cooling - Whisper Power W-SQ 6 Installation Manual

INSTALLATION
3 FUEL PIPES
When the tank is above the generating set (figure 11) we
recommend ending the return line on the top of the tank.
When the return is on the top - in case of a leakage the
return line cannot overflow because of siphoning. One will
only need a fuel cock in the fuel supply line. When the tank
is below the generating set we recommend ending the
return line on the bottom of the tank (A) below the inlet of
the supply line.
Both supply and return fuel pipe lines should be
appropriate material and 8 mm outer diameter tubing. The
quality of the tubing of fuel pipes could be submitted to
local regulations depending on the application of the
vehicle.
The fuel pipes can be plumbed to the flexible hoses which
are on the generating set and have a connection to fit to 8
mm pipe. This fuel line fulfils CE standards and is in
accordance with ISO 7840 A2.
It is important to avoid bends in the pipes, as they could
trap air bubbles. The return pipe should never be
connected to the suction pipe. The return line should be of
8 mm diameter and go straight back via the top to the
bottom of the tank. When the return is too narrow, has too
many bends and goes back to the bottom of the fuel tank,
the back-pressure could be too high. This results in
irregular running of the engine. When the engine runs
irregular, one can check if back-pressure is the problem by
disconnecting the return line just outside the canopy and
draining it in a canister. When the engine runs smooth
now, the return piping has to be changed. It could also
help to install a second (electrical 12V) fuel lift pump in the
supply line to increase the pressure.
4 FUEL FILTERS
A fine fuel filter is installed which requires maintenance.
WhisperPower advises to install an extra fuel filter/ water
fuel separator near the fuel tank.
Before starting your generating set for the first time follow
the fuel system bleeding procedure in the user's manual.

Radiator cooling

2.5.2.1 TopCool radiator system
Where a roof-mounted cooling system is chosen,
WhisperPower offers the TopCool system for optimum
ease of installation,. This is an integrated system holding
two radiators, one radiator for the diesel engine and the
other one for cooling the AC alternator. Integrated in the
system, the expansion tanks are always positioned at the
right altitude. The TopCool can be mounted in two
directions as shown below.

Detailed installation instructions are provided with these
systems.
2.5.2.2 Other radiator cooling systems
1 GENERAL INSTRUCTIONS
The radiators can be mounted below the floor, in the side
or on the roof of the vehicle. Wherever the radiators are
mounted the well-functioning of the system depends on
the circulation of the coolant. Roof mounted radiators bring
the most risk for circulation problems, because air trapped
in the radiators or a low level of the coolant, will
immediately affect the cooling capacity of the radiators. It
is recommended to keep the radiators as close as possible
to the unit. The piping should be fitted as direct as
possible.
When the radiators are above the engine, the piping
should be fitted below the top of the radiators! (refer to
