Overview 

 

Warranty 

 

A. Warranty is based on the general terms and conditions of the manufacturer. The warranty is void if the equipment is 
repaired or modified without the written approval of the manufacturer, if the operating limits are exceeded or if the control 
system or the electrical wiring is modified. Damage due to misuse, lack of maintenance or failure to comply with the 
manufacturer’s instructions or recommendations is not covered by the warranty obligation. If the user does not conform 
to the rules of this manual, it may entail cancellation of warranty and liabilities by the manufacturer. 
 
B. Warranty is twelve (12) months as from the date of first start up at installation place or eighteen (18) months after 
delivery at the project or other delivery location indicated by the customer. The date the unit is operated for the first time 
means the date reported in the “1st start up form” contained into the “unit log book”. This form should be filled in and 
sent, within 8 days from the start up, to Trane. 
 
C. The warranty is valid if all the installation and start-up instructions have been adhered to (both those which may have 
come from Trane and those coming from current practice), if the 

“1st start up form” has been filled in and sent to the 

Trane after sales department. 
 
D. The warranty is subject to any faults or defects being reported within eight days from their discovery. The warranty will 
only be applied if and when the purchaser suspends use of the equipment as soon as a defect has been found. 
 
E. The warranty is valid if the first running of the unit is carried out by a Trane authorized assistance center. 
 
F. The warranty is subject to regular maintenance of the unit which is appropriately indicated in the “unit log book” locat-
ed inside the electrical panel. 
 
G. Warranty automatically ends in case of payments not fulfilled, non-performance of the contract and even if the units 
show tampering without TRANE written approvals. 

 

Receiving the unit 

On receiving the unit, it is up to the customer to check that there is no obvious damage or pieces missing. If this is so, an 
immediate complaint must be made to the carrier for damage or for not-delivery and the Receiving Card to be found 
inside the unit electrical panel must be filled in. Photographic evidence must be provided for macroscopic damage. The 
card must be sent to Trane within 8 days of receiving the goods: if it is not sent back or delayed, the complaint will not be 
accepted. 
 

Factory inspection 

Units  are inspected  in  the factory,  in appropriate  areas,  in  accordance  with internal procedures.  Each  performance  test 
carried  out  on  the  unit  is  possible  only  if  the  same  conditions  are  reproduced  and  maintained  (charge  consistency, 
constant  temperature  and  evaporation  -  condensation  and  recovery  capacity,  quality  and  tolerance  of  the  measuring 
instruments etc.) in the test rooms. 

The inspection conditions are those indicated by the customer in the ordering phase: if not otherwise specified, reference 
should be made to the nominal performance indicated in the product catalog in force at the date of the Confirmation of 
the Order. 
 

Improper uses 

The  unit  is  projected  and  built  up  to  grant  the  maximum  safety  in  its  proximity,  as  well  as  to  resist  to  the  aggressive 
environmental conditions. The fans are protected by grilles. Residual risks are indicated with warning labels.
