CTC EcoZenith C 530 l 510 

For the property owner

4.  Operation and maintenance

When your new CTC EcoZenith C 530 or 510 has been installed, you should, 
together with the installation technician, ensure that the installation is optimal. 
Let the technician show you how it works and should be maintained. Purge  
the radiators after about three day’s operation and add water as necessary.

4.1 

Safety valve for the tank and 

radiator system

Check regularly that the valve is working properly by manually turning the 
valve knob. Check that water comes out of the overflow pipe. The overflow 
pipe outlet must always be open. Hot water can drip from the safety valve.

4.2 

Draining the tank

There must be no electrical supply to the tank during drainage. The drain 
valve is packaged separately and can be connected directly onto one of the 
lower connections, if one is free, or to a low lying pipe. When draining the 
whole system, fully open the mixing valve, i.e. turn it as far as possible anti-
clockwise. Air must be applied to a closed system.

4.3 

Operation stop

If there is a risk of the water freezing when the system is not in use, all the 
water must be drained from the tank and radiator system. The hot water 
coils, which contain about eleven litres, are emptied by feeding a hose all 
the way down inside the coils into the cold water connections and then 
siphoning out the water.

4.4 

Noise problems

Sudden changes in pressure in the tap water system may cause noise. This 
is due to pressure surges which occur when, for instance, an older type of 
instant closing mixer is turned off quickly. The fault is not in CTC EcoZenith 
C 530, and the problem can be easily rectified by replacing the mixer with 
a soft-closing one. In the case of noise from hard closing dishwashers and 
washing machines, this can be rectified with a pressure surge damper, which 
is also a viable alternative to soft closing taps/mixers. Minimizing pressure 
surge benefits the whole of the tap water system generally. 

If pouring sounds come from the unit, check that it is well purged. Turn 
the boiler safety valve to evacuate any air in the system. If the problem is 
repeated, have a specialist check the cause.
