16 DEVICE CLEANING AND
MAINTENANCE
b
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
b
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).
