24. Check the solar pipe work and collector unions for leaks whilst the pump is
operating and the solar circuit is at its working pressure. It is important to
check all of the solar circuit pipe work, including in the roof space and on
the roof.
25. If the procedure to check the solar pipe work for leaks is not complete
before the pump has automatically turned off, then:
ƒ switch off the electrical supply at the isolating switch to the solar
storage tank.
ƒ wait one (1) minute for the operating system to reset to its
commissioning sequence, otherwise the pump may not operate when
the power supply is switched on.
