OTHER CHECKS
15.8.1 RELIEF VALVE
At least once a year, the temperature and pressure relief valve and safety valve should be checked to ensure that
they are in operating condition. To check each valve, lift the lever or turn the screw cap at the end of the valve
several times. The valve should operate freely and seat properly.
If water does not flow, remove and inspect for obstructions or corrosion. Replace with a new valve of the
recommended size as necessary.
15.9
FLUE SYSTEM
Examine the exhaust and ventilation system at least once a year. Points of inspection are as follows:
1.
Check for obstructions and/or deterioration of flue pipe and terminal. Replace immediately where
needed.
2.
Check the terminal for any foreign material and remove as necessary.
3.
Check all flue system connections for leakage and re-seal as required.
4.
Check that ventilation grilles comply with current regulations (where applicable).
15.9.1 CORREX ELECTRICAL ANODE PROTECTION SYSTEM
When the protection system is working correctly, a green light should be visible on the Correx unit. If an error
occurs, this lamp will flash red. Remedial action should be taken as a matter of urgency if such a situation arises.
The Correx system passes and monitors an electrical current flow through the water. If this current flow becomes
too high or too low, a fault is indicated. Factors that may cause incorrect current flow include:
Short-circuiting of the cables between the potentiostat and electrodes.
Poor conductivity between the electrode cables and electrode connection tabs.
Poor conductivity between the electrode connection tabs and electrode PCB.
Poor conductivity between the storage vessel and earth tab.
Poor conductivity between the earth tab and earth cable.
Deposits forming on the electrodes.
