COMMISSIONING AND MAINTENANCE

16  DEVICE CLEANING AND 

MAINTENANCE

Service the system at least once a year and carry out 

the inspections specified in the relevant manual.

The following operations must be exclusively performed by 

Technical Assistance Centre.

16 1 Checking the seals

After commissioning, check hydraulic fitting sealing. Make 

sure there is no leakage close to electric components to 

avoid short-circuits.

16 2 External cleaning

If the insulation get dusty, clean it with a dry rag.

Do not use abrasive products, petrol or triethylene.

17  INTERVENTIONS ON THE 

HYDRAULIC SYSTEM

17 1 Draining the system

-  Connect a rubber hose to taps (A) and (B)

-  Connect the opposite end to a vessel

-  Open system drain taps and allow full drainage

-  Close system drain taps and remove the rubber hose

-  The exhausted heat transfer fluid must be disposed 

of according to the prevailing regulations, pursuant 

to the instructions provided in the safety data sheet 

supplied with the glycol.

17 2 Disassembling the circulator

Remove the circulator when system has cooled down.

Before removing circulator (C):

-  Cut power off to the solar station and to the connect-

ed integration system, by setting the system's main 

switch and the device's main switch to OFF

-  Disconnect circulator power by removing connectors 

(D) and (E)

-  Move away any wiring and electric devices below to 

protect them against any leakage of heat transfer fluid

-  Close the valve (VR) by turning the handle 90° clock-

wise

-  Open taps (A) and (B) and drain the solar circuit

-  Loosen ring nuts (H1) and (H2) and remove circulator 

(C).

18  RECYCLING AND DISPOSAL

The device is primarily composed of:

Material

Component

metal materials

tubes, circulator

PPE (polypropylene foam)

insulation

electrical and electronic 

components

cable and wiring, circulator

At the end of the device's useful life, these components 

must be separated and disposed of according to current 

regulations in the country of installation.
