The live supply to the solar pump MUST be run in series through
terminals 3 and 5 from the solar control to the pump for this to be
operative as the solar TCO.

e Without earthing, life-threatening voltage can reach
the piping and water draw-off points.
- Earth the cylinder.
• The electric immersion heater must be earthed.
• Dismantle the electric immersion heater cover.
• Install a separate electrical power supply for the electric
immersion heater in accordance with current IEE regulations
(BS 7671).
- Use heat-resistant cables (H05BN4-F 1.5 mm² 3 core HOFR
sheathed flexible cable) for the cabling of the electric
immersion heater.
- Use the cable grip (2) to firmly secure the supply cable of the
immersion heater.
- Connect the electric immersion heater to the power mains via
double pole isolating switch with a contact separation of at
least 3 mm in both poles.
- Protect the circuit using a 13 A fuse. Mount the cover for the
electric immersion heater.
Only switch the immersion heater on once the cylinder
is completely full.
With the circuit breaker, the electric immersion heater can be
switched on if the reheating device has malfunctioned.
