  INSTRUCTIONS FOR MAINTENANCE AND INITIAL CHECK

  3.1 

GENERAL  RECOMMENDATIONS

Operators who install and service the appliance must wear the personal protective equipment 
(PPE) required by applicable law.
The list of possible PPE is not complete as they are indicated by the employer.

Before carrying out any maintenance work, make sure that:
–  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 maintenance 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 refrigerant gas.
This gas is ODOURLESS.
Pay the utmost attention
Strictly follow the instruction handbook of the Audax Pro V2 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).

INITIAL  CHECK

To commission the package, you must:

-  check connection to a 230V-50Hz power mains, correct L-N polarity and the earthing connection;
-  make sure the central heating system is filled with water and the indoor unit pressure gauge reads a pressure of 1-1.2 bar;
-  make sure the chiller circuit has been filled according to what is described in the outdoor unit instructions booklet;
-  check the activation of the main switch located upstream of the indoor unit;
-  ensure activation of all adjustment devices;
-  check the production of DHW (if paired with a storage tank unit);
-  check the tightness of the hydraulic circuits;
