This warranty applies to Mitsubishi Electric Ventilation Products, Controllers, Accessories and Peripherals sold by 
Black Diamond Technologies Limited in New Zealand.

installation/third party components nor does it cover design or airflow 
calculations which are the responsibility of the third party contractor.

is applicable to the original purchaser. Equipment defects covered 
by this warranty will be repaired or replaced at the discretion of Black 
Diamond Technologies Limited without cost to the owner for parts or 
direct repair labour. A Black Diamond Technologies Limited authorised 
repair company shall carry out the repair or replacement during 
normal business hours.
Any Mitsubishi Electric parts or equipment replaced under the 
warranty will be warranted in accordance with the provisions of this 
warranty for the remainder of the original warranty period or 12 months 
from the completion of the repair, whichever is the greater.

rights given by this warranty, all other warranties and all liability of

Important Installer Responsibilities
BDT places high importance on correct installation and long-term 
serviceability. Therefore:
•	
Installers are responsible for ensuring safe, compliant and 
adequate access to the product.
•	
Poor access impacting maintenance, service or repair is not 
considered a manufacturer fault and will not be covered under 
this warranty.
•	
BDT will not cover labour, materials, or equipment costs (such as 
scaffolding, cranes, elevated work platforms, building costs etc.) 
resulting from inaccessible, unsafe or non-compliant installations.
Excluded from Manufacturer 
Warranty Coverage:
•	
Electrical cabling or control wiring
•	
Drainage systems
•	
Ducting
•	
External control devices or accessories not manufactured by 
Mitsubishi Electric
Responsibility for the performance, specification, and installation of 
these components rests solely with the installer, or end user where 
both parties have reached an agreement prior to the installation.
Special Exclusions:
1.	
Any product imported by an individual or distributor other than 
Black Diamond Technologies Limited, is not covered under 
this warranty.
2.	
Any labour costs inflated by difficult access to the unit, and 
any extra costs due to difficult access to equipment. Any 
costs or additional labour associated with gaining acceptable 
service access to equipment installed in restricted or unsafe 
locations. Includes crane, lift platform, hiab costs where access 
necessitates the use of this equipment.

(including system replacement) where systems have been 
incorrectly sized or installed.

All equipment components, installed in corrosive or potentially 
corrosive environments (including but not limited to; coastal, 
geothermal, industrial or chemically contaminated environments, 
or where insufficiently filtered outside air is introduced indoors) 
must be assessed along with microclimatic factors and provided 
with corrosion protection appropriate to the environment prior to 
installation. Failure of components (and/or subsequent resultant 
damage or faults) due to corrosion or rust is not a manufacturing 
defect where corrosion protection has not been correctly 
specified, applied, or maintained. Black Diamond Technologies 
Limited does not control site conditions, aftermarket protection 
methods, or ongoing maintenance practices and therefore 
cannot accept warranty claims for corrosion-related damage, 
even where additional protection has been applied.
