that is built to the highest possible 
quality standards using state of the 
art technology.
• Please check the items delivered, 

to ensure that they are complete 
and match your order. Inspect 
for any transport damage that 
may have occurred, if necessary 
re-porting it to your Installer or 
nearest Customer Service Centre. 
Complaints made later cannot be 
accepted due to insurance ar-
rangements. 

•  For a correct installation, pay at-

tention to laws currently in force, 
plus any regulations and stan-
dards, in particular regulations laid 
down by the relevant utility compa-
ny. In case of queries, please con-
sult your installer or your nearest 
Hoval Customer Ser-vice Centre. 

•  Before start-up, the installation 

must be inspected and released 
for use by the installer.

trouble free operation, only use 
your Hoval heat pump in accor-
dance with these operating instruc-
tions.

built, and for which it has been ap-
proved by Hoval.

•  Do not make any modifications to 

the equipment, as this will result in 
invalidating all legal claims. Con-
version kits must be installed by, 
and obtained from, the licensed 
installer or Hoval Customer Ser-
vices.

• 

In the event of damage or mal-
function, find out about the repairs

uct you also have the protection of a
