INTERVENTIONS ON THE HYDRAULIC
SYSTEM
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.
Disassembling the circulator
b
Remove the circulator when system has cooled down.
Before removing circulator (C):

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 valves (VR) and (VM) by turning handle clock-
wise by 90°
- Open taps (A) and (B) and drain the solar circuit
