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 closed the gas isolation valve;
– you have discharged the pressure from the system and domestic hot water circuit (if the stor-
age tank unit is present).
Risk of material damage after using sprays and liquids to search for leaks
Leak sprays and liquids clog the reference hole P.Ref. (Fig. 55) of the gas valve, damaging it irreparably.
During installation and maintenance, do not use spray or liquids in the upper area of the gas valve (electric connections side).
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.
