Putting It Into Service - Innova 3in1 5M Installer Manual

3�1 Preliminary warnings
The initial start-up of the heat pump must be carried out
by the Service Centre.
The customer must be present when the appliance is test-
ed and informed of the contents of the manual and proce-
dures. After commissioning, the manual and the warranty
certificate must be handed over to the customer.
Before start-up, all work (electrical and plumbing connec-
tions, filling and venting of air from the plant) must be
completed.
Remove any dirt or debris from the inside of the appliance,
especially chips, wire pieces and screws.
The unit can be supplied with factory-fitted configuration
accessories. For instructions on these accessories, see sec-
tion "Configuration accessories" p. 46.
Make sure that:
• all safety conditions have been met
• the minimum technical clearances have been respected
• the hydraulic connections have been made according to
the instructions in the manual
• the hydraulic plant has been filled and vented

ueduct should always be carefully analysed. If necessary,
condition with appropriate treatment systems.
If a softener is installed, in addition to following the man-
ufacturer's instructions, adjust the outlet water hardness
to not less than 5 °F (by performing pH and salinity tests)
and check the outlet chloride concentration after adjust-
ing the resins.
