GENERAL WARNINGS.

Operators who install and service the
appliance must wear the personal pro-
tective equipment (PPE) required by
applicable law.
The list of possible PPE is not complete
as they are indicated by the employer.
Before performing any maintenance
operation, make sure:
- you have disconnected the power to
the appliance;
- you have discharged the pressure from
the system and domestic hot water
circuit.
Supply of spare parts
The device's warranty shall be rendered null and void
if unapproved or unsuitable parts are used for main-
tenance or repairs. These will also compromise the product's
compliance, and the said product may no longer be valid and
fail to meet the current regulations. in regard to the above, only
use original Immergas spare parts when replacing components.
If additional documentation needs to be consulted for
extraordinary maintenance, contact the Authorised
After-Sales Service.
The appliance operates with R32 refrig-
erant gas.
This gas is ODOURLESS.
Pay the utmost attention.
Strictly follow the instruction handbook of the
outdoor condensing unit before installation
and any type of operation on the cooling line.
R32 refrigerant gas belongs to the low
flammability refrigerant category: class
A2L according to standard ISO 817. It
guarantees high performance with low
environmental impact. The new gas reduces
the potential environmental impact by one
third compared to R410A, having less effect
on global warning (GWP 675).
