Pre-start guidelines (Power OFF)
Power OFF checks are performed with the main circuit breaker between the
WhisperGen
TM
and the battery bank in the OFF position.
The pre-start (Power OFF) process consists of the below procedures:
Installation check
(check that the installation has been completed as per
the Installation checklist in the DC Installation Manual)
Visual check
Checking and adjusting nitrogen pressure
Determining battery type and capacity
Checking Battery Bank Connections
Checking the Fuel
Checking the Coolant
Visual check
It is important to visually check the overall heating and electrical system into
which the WhisperGen
TM
has been installed. If the wider system does not
meet the design and component specifications defined in the Installation
Manual, then there could be risks to the safety of operators and to the
performance and reliability of the unit.
Only begin the commissioning if you are satisfied that the installation has
been carried out as described in the DC Installation Manual. The key areas
to check are highlighted in the Installation checklist at the back of the DC
Installation Manual, which should be signed and dated.
Request to see the completed installation checklist and installer declaration
from the WhisperGen
TM
DC Installation Manual. The installer should have
completed this checklist, certified installation according to the Installation
Manual and accepted liability for re-installation costs.

Pre-start guidelines (Power OFF) Checking and adjusting nitrogen pressure
5
Checking and adjusting nitrogen pressure
Overview The Nitrogen pressure at cold (before running), should be 24 bar, as set in
the factory. This should be checked, and the pressure topped up or
reduced if it is more than 2 bar from the target level. Ambient temperature
will vary nitrogen pressure. The Nitrogen pressure when hot (running at
preset Block temperature), should be 28 bar. You should check the
Nitrogen pressure both when cold and when hot.
Procedure
Checking Nitrogen pressure:
1. With the engine cover removed, remove the cap from the nitrogen
filling point located on the right-hand side of engine.
2. Ensure the valves on the hose assembly are closed.
3. Fit the hose (secondary valve end) to the regulator on the nitrogen
bottle.
4. Fit the running nut of the hose to the nitrogen filling point on the
WhisperGen
TM
as shown below:
5. Open the secondary valve and check the pressure on the gauge.
6. Close the secondary valve.
Adjusting Nitrogen pressure:
1. Fit the hose (secondary valve end) to the regulator on the nitrogen
bottle.
2. Open the isolating valve on the nitrogen bottle and set the regulator to
the desired charge pressure.
3. Open the secondary valve and check the pressure on the gauge.
Adjust the regulator if necessary.
4. Open the primary valve. The WhisperGen
TM
starts to pressurise. Allow
the pressure gauge to stabilise.
Introduce Nitrogen slowly. Add Nitrogen at a rate of 1 bar /
minute. Adding Nitrogen too quickly damages WhisperGen
TM
seals.

Determining battery type and capacity Pre-start guidelines (Power OFF)
6
5. Check the pressure.
6. Close the secondary valve and close the nitrogen bottle isolating valve.
7. Once the pressure is checked and confirmed to be at the correct level,
leave the pressure gauge attached to the WhisperGen
TM
as it will be
required again later in the commissioning process.
8. Remove the hose assembly from the WhisperGen
TM
charging point
and refit the cap to the charge point.
Determining battery type and capacity
Knowing the battery bank capacity is important as it affects the charging
characteristics and control parameters in the WhisperGen
TM
.
Because of the WhisperGen
TM
automatic battery monitoring functionality
the minimum battery bank capacity is 200Ah @ 12V and 100Ah @ 24V.
The WhisperGen
TM
is capable of charging a larger battery bank, such as a
1000Ah @ 12V or a 500Ah @ 24V battery bank.
A WhisperGen
TM
can reduce the need for a very large battery bank capacity
by regularly recharging a battery bank. Typically, battery bank capacity can
be half of that in more traditional installations.
The type and capacity of the battery bank can be determined from the
manufacturers' labels. If the labels are obscured from view, then obtain
documentation from the installer confirming the battery bank type and
capacity.
Incorrect capacity settings will result in incomplete charging and
may also damage the battery bank.
The figures and settings outlined in this guide relate to new
batteries or batteries that have been tested and can be demonstrated to be
in good condition.
Older batteries may have different or reduced charging
characteristics, so settings have to be modified to suit. Worn out batteries
take longer to charge and may never reach full capacity.

Pre-start guidelines (Power OFF) Checking Battery Bank Connections
7
Checking Battery Bank Connections
Overview
Power flows between the WhisperGen
TM
and battery bank via two power
cables connected to the terminals of the battery bank. The WhisperGen
TM
also monitors the battery bank voltage, current, and temperature via
electrical wires connected to the battery bank. The WhisperGen
TM
should
not be running when you check the connections.
If an electrical fault or warning occurs, electrical connections may need to be
checked – refer to the User Manual troubleshooting section.
Procedure
To check the battery bank connections:
1. Access the battery bank managed by the WhisperGen
TM
, and ensure
that the battery bank connections, as shown below, are intact and

Checking the Fuel Pre-start guidelines (Power OFF)
8
Checking the Fuel
Overview
The fuel level should be checked regularly to ensure a constant fuel supply to
the WhisperGen
TM
. How often the fuel needs to be checked and replenished
depends on the operating conditions of the WhisperGen
TM
and the size of the
fuel tank.
In general, the WhisperGen
TM
consumes 0.5 to 0.85 litres of fuel per hour of
operation. This applies to machines using either diesel or kerosene fuel.
Use only good quality automotive diesel (EN590 or BS2869: 2000
burner fuel class A2, D, minimum flash point, closed 56°C). Do not use other
fuel types such as bio diesel, heating oil, petrol, aviation fuel, and LPG.
Procedure
To check the fuel level:
1. Remove the fuel tank cap. The fuel tank is located outside the
WhisperGen
TM
and is typically within five metres of it.
2. Ensure that the fuel level is adequate. The fuel level must be higher than
the fuel outlet point at all times.

Minimum Inadequate
Outlet Outlet
Fuel Fuel
3. Replenish fuel if necessary, taking care not to spill any on or in the
vicinity of the WhisperGen
TM
.
4. Replace the fuel tank cap.
If the fuel tank was empty and a fuel-related error message is displayed on
the control panel, you will need to bleed the fuel line before the
WhisperGen
TM
can be operated normally again.
If you need to bleed the fuel line then see bleed the fuel system on page 13.

Pre-start guidelines (Power OFF) Checking the Coolant
9
Checking the Coolant
Overview
The coolant level should be checked regularly to ensure a constant
circulation of coolant through the WhisperGen
TM
. How often the coolant
needs to be checked and replenished depends on the size of the coolant
header tank and the coolant circuit.
Use clean distilled water and high quality marine-grade corrosion inhibitor,
suitable for use with aluminium and any other metals that may be
encountered in the system (i.e. steel, copper).
If freezing conditions are expected, a marine-grade anti-freeze and
corrosion inhibitor is to be used. All additives must be pre-mixed. Follow the
dilution recommendation of the manufacturer.
The cooling system of the WhisperGen
TM
is vital to its
performance. If the coolant level is not maintained correctly, damage may
occur.
Glycol can be harmful if swallowed or inhaled. Do not store it in
open or unlabelled containers. Wash your hands thoroughly after handling
them.
Using an incorrect type of coolant can cause serious corrosion in
the WhisperGen
TM
- use only the recommended coolant.
Ensure that the coolant is free of particulate contaminants.
Foreign particles in the coolant can obstruct coolant passages in the engine,
resulting in damage to the WhisperGen
TM
.
Do not connect the boat's main engine cooling system to the
same circuit as the WhisperGen
TM
, as cast iron contaminants may damage
critical internal components.
If the coolant system is used to heat the vessel potable water
system, a compatible non-toxic corrosion inhibitor (and anti-freeze if
required) must be used.
Procedure
To check the coolant level:
1. Remove the coolant header tank cap.
The WhisperGen
TM
coolant header tank is typically located
outside and above the WhisperGen
TM
.
2. Ensure that the coolant level is adequate. The coolant level must be
between the maximum (1) and minimum (2) levels at all times.
12
3. Replenish coolant if necessary.
4. Replace the coolant header tank cap.

Fill and bleed the primary coolant system Pre-start guidelines (Power ON)
10
Pre-start guidelines (Power ON)
Power ON checks and settings are made with the main circuit breaker
between the WhisperGen
TM
and the battery bank in the ON position. Do not
attempt to start the WhisperGen
TM
at this point.
The pre-start (Power ON) process consists of the below procedures:
Fill and bleed the primary coolant system
Bleed the secondary cooling system
Bleed the fuel system
Connect and check Micromon
Set variables with Micromon
These tasks require power from the battery bank to be connected to the
WhisperGen
TM
. Provided the installation is correct, this should simply
require switching on the main circuit breaker.
Fill and bleed the primary coolant system
Overview The primary coolant system must be filled and then the pump operated via
the WhisperGen control panel to bleed air from the system.
Use only the specified coolant. Use of incorrect coolant will
result in corrosion to the WhisperGen.
Procedure When the coolant system is complete, the battery bank is installed and all
electrical wiring and connections have been made, the coolant system can
be filled and bled as follows:
1. Remove the engine enclosure. See Remove and re-fit the enclosure.

Battery charging overview Pre-start guidelines (Power ON)
14
Battery charging overview
Battery charging cycles
Every time the WhisperGen
TM
is operated, it charges the battery bank and
is in one of these three charging states depending on settings. There are
three states for a typical charging cycle as shown in the diagram below:
User controller settings affect the bulk-charging and auto-charging settings
only. Absorption and float charging are set up via Micromon.
Three stage charging
The default settings used in this manual relate to a standard sized battery
bank of 100Ah for 24V and 200Ah for 12V systems.
The WhisperGen
TM
has a three stage charging cycle.
1. Bulk Charge:
The battery is accepting all the available charging current. Cell voltage
jumps to approximately 2.1V per cell then slowly rises until the first
voltage limit is reached. A deeply discharged battery will accept a high
charge current until it is about 80% charged. This is when the
absorption level of the battery is reached.
2. Absorption Charge:
When the absorption level of the battery is reached charging is limited
to the amount of current that the battery will absorb at the absorption
voltage. During the absorption phase the current will steadily decrease
as the battery reaches its fully charged state.
3. Float Charge:
After the battery has been fully charged it is kept at a lower constant
voltage to compensate for self-discharge to keep the battery fully
charged.
