COMMISSIONING AND MAINTENANCE
16 DEVICE CLEANING AND MAINTENANCE
9
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 Service.
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
Use a dry rag to clean the insulation and the solar regulator dis-
play (if present) to remove any dust.

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
9
Remove the circulator when system has cooled down.
Before removing circulator (C):
− Cut power off to the solar station and to the connected
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 pro-
tect them against any leakage of heat transfer fluid
− Close valves (VR) and (VM) by turning handle clockwise by
90°
− 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
ABS (acrylonitrile-butadiene-
styrene)
solar regulator housing
EPP (polypropylene foam) insulation
electrical and electronic
components
cables and wiring, solar
regulator, 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.
