and  the  radiator  fan  sucking  exhaust  gasses  into  the 

radiators. 

The generator and other parts should be protected against 

the influences of the weather and splashing water (with dirt 

and  salt)  below  the  vehicle.  Refer  to  the  installation 

manual  for  instructions  but  remember  these  are  for 

guidance only as many factors influence the installation of 

a generator. The ultimate responsibility will always be with 

the owner to ensure a safe and compliant installation. If in 

doubt ask!  

 

Example 2: Misuse: 

Long term running with no load or too little load can cause 

the  exhaust  to  get  choked  with  soot  or  carbon.  Cleaning 

the exhaust is not covered by guarantee.  

 

Example 3: Neglect 

Whisper  generators  have  an  option  for  an  auto  start/stop 

mode or interval mode.  

Whisper  Power

  cannot  be  held  responsible  for  damage 

caused by the unattended running generator. 

 

Guarantee  means  that  faulty  parts  are  repaired  or 

replaced free of charge. If necessary the whole generator 

unit  will  be  exchanged.  Labour  necessary  to  complete 

repairs  on  board  a  vessel  executed  by  an  authorized 

service engineer is covered, but is limited to a reasonable 

number  of  hours  and  reasonable  rates  in  relation  to  the 

actual repair work that has to be done.  

Travel  expenses  and  travel  hours  are  not  covered.  Also 

not covered is the labour required to take a generator out 

of  a  vehicle  or  for  reinstallation.  There  is  no  cover  for 

labour needed to get access to the generator, for example 

to remove equipment or parts of the vehicle body etc.  

 

Goods  to  be  delivered  under  guarantee  will  be  invoiced. 

Only after the faulty goods are returned will the invoice be 

credited.  Payment  in  advance  may  be  required  or 

guaranteed  by  credit  card.  If  after  the  faulty  goods  are 

returned, it is indicated that the failure was not covered by 

guarantee  a  credit  will  not  be  issued.  For  example  if  a 

Printed  Circuit  Board  is  returned  with  clear  damage 

caused by water, guarantee will be refused.  

Freight costs to deliver spares by normal mail or carriers is 

covered  under  guarantee.  Special  services  like  express 

mail, overnight delivery etc. are not covered. Taxes and  

duties are not covered. For shipments to remote areas any 

additional  costs  incurred  over  normal  carriage  will  be 

invoiced to the customer.  

The  cost  for  returning  faulty  goods  is  not  covered  under 

guarantee.  

 

If any problem arises which could be subject of guarantee, 

procedures  should  be  followed  as  described  in  the 

guarantee  conditions,  unauthorised  repairs  could  lead  to 

further damage and violate the guarantee conditions.  

 

Should  work  take  place,  which  is  not  in 

accordance  with  the  guidelines,  instructions 

and  specifications  contained  in  this  user’s 

manual  and  the  supplementary  installation 

manual,  then  damage  may  occur  and  the 

generating set may not fulfil its specifications. 

In all these cases the guarantee may become 

invalid. Use original spareparts only! 

 

 

1.4 

LIABILITY 

Whisper Power

 does not accept responsibility for damage, 

injuries  or  casualties  which  are  the  result  of  operation  of 

the  generating  set  in  specific  conditions  which  brings 

dangers which could not be foreseen, or could be avoided 

by  additional  measures. 

Whisper  Power

  does  not  accept 

liability  for  damage  due  to  use  of  the  generator,  possible 

errors in the manuals and the results thereof.  

 

Automatic start/stop  

Whisper  Power

  cannot  be  held  responsible  for 

damage  caused  by  the  unattended  running  generator 

using the auto-start/stop mode or interval mode.  

 

1.5 

IDENTIFICATION  

1.5.1 

General  

Before  using  this  generating  set  it  is  very  important  to 

identify  the  set  correctly.  To  communicate  for  service  or 

ordering  parts  it  is  also  essential  to  correctly  identify  the 

generating set. Also for the daily operation of the genera-

ting set it is necessary that the operator knows the correct 

specifications.
