Warranty 

 
Your LE-450 turbine from Leading Edge Turbines (LET) carries a two-year warranty, as supported by 
a  retailer’s  receipt.  The  warranty  starts  from  the  date  of  installation  or  ninety  (90)  days  after 
shipment from the LET factory, whichever comes first. 
 
LET will supply ‘non-wearing’ parts at no cost. For minor component failures, replacements may be 
sent directly to the customer / dealer for replacement by them. For more serious defects we may 
suggest a ‘return-to-base’ arrangement for replacement or repair. 
 
In  these  cases,  the  purchaser  will  be  responsible  for  taking  the  turbine  off  the  tower/mast  and 
paying the return carriage costs.  
 
Where  a  turbine  is  to  be  replaced,  it  must  be  returned  to  LET  before  the  replacement  unit  is 
despatched.  Should  the  product  prove  to  be  irreparable,  LET  reserves  the  right  to  substitute  an 
equivalent product, if available. 
 
This warranty does not extend to servicing a faulty turbine on location. 
 
In  all  cases  LET  will  take  reasonable  action  to  ensure  customer  satisfaction.  You  should  always 
receive a warm, courteous service in or out of your warranty period. 
 
Your  turbine  must  be  installed  and  operated  in  accordance  with  the  guide.  Failure  to  do  so  will 
result  in  this  warranty  becoming  null  and  void.  Any  unauthorised  modifications  to  the  turbine 
design will void the warranty and may compromise the safety of the machine. 
 
What is not covered by your warranty? 
 

 

Damage  caused  by  unsatisfactory  installation  of  the  turbine,  tower  and/or  control 
equipment. 

 

Damage  caused  by  the  neglect  of  periodic  maintenance  in  the  manner  recommended  in 
the installation manual. 

 

Damage caused by repair or maintenance performed using methods not specified by LET 
or by non-authorised dealers of LET products.

lubricants in or on the turbine, tower or control equipment. 

 

Damage  caused  by  operating  the  turbine  in  conditions  outside  of  those  specified  in  the 
Owner’s  Guide  –  including,  but  not  limited  to,  allowing  the  turbine  to  run  while 
disconnected  from  the  batteries  or  not  configuring  the  Tristar  charge  controller  for 
diversion mode. 

 

Damage caused by modifications to the turbine, tower or control equipment not approved 
by LET. 

 

Damage  caused  to  the  turbine,  tower  and  control  equipment  by  improper  storage  or 
transport. 

 

Damage caused by lightning strikes, flooding, fire, etc. 

 

Damage due to extremely high winds and storm conditions (18m/s, 40mph) and locations 
off-shore. 

 

Damage caused by flying debris. 

 

Damage  to  batteries  due  to  excessive  deep  discharge,  short-circuiting,  excessively  high 
load,  over  charging,  loss  of  electrolyte,  or  any  condition  outside  of  the  manufacturer's 
specification for battery use.
