11.0 COMMISSIONING AND TESTING
WATER CONNECTIONS
See Section 8.6: WATER CONNECTIONS
The system should be thoroughly flushed out with cold water without any circulating pumps in position.
Ensure all the valves are open.
Check the system for leaks and repair as necessary. If the system is configured in a sealed arrangement, check the expansion
vessel cushion pressure and pressurisation unit settings.
TEMPERATURE ADJUSTMENT PROCEDURE
Once filled with water, and before use, or if the system has been drained down for a period of time, it is important to check the
operation of the valve – switch on the controller and set the temperature to a high level (temperature altered by raising the set point).
The actuator should slowly rotate until the valve is at the fully diverting position and then stop. Now lower the temperature (below
ambient), and the actuator should rotate anti-clockwise and stop at around the fully open position.
If the actuator does not move, or does not turn full travel, then switch off at the panel, the controller is not functioning correctly and
will need to be investigated further.
