1 bottle will treat around 10 radiators.
No, you leave CG1 in the system, topping up if any water is lost from the system.
Yes, once you have reached the time limit, drain the system fully to remove all system water, debris/sludge and CG3 contained within the system.
No, but the clean that CG3 has carried out will not be as effective as if the cleaner was removed in 3-4 weeks after having dosed the system.
The clean will not be effective and problems may occur in future, as the contaminants have not been removed.
Most systems. Not recommend for use in direct or primatic systems.
Yes, CG3 will help to remove potentially harmful installation debris.
Drain down fully and refill 3 times (drain, fill, drain, fill, drain, fill).
Yes. Doubling the dosage will increase the concentration of the chemical and make for a quicker clean.
Where a system is dirty and requires cleaning, CG3 should be used to remove deposits and build ups in the system, which can do damage to the inside of a central heating system and its components.
After cleaning a system, CG1 should be added as protection for the system.
Products can be introduced to a central heating system via an F&E tank, if the system is an ‘open’ system. Enough water should be removed so that the central heating system requires a refill, which will draw water from the tank and circulate it.
For a ‘sealed’ system, add wherever you can access the system (towel rail, radiator, filling loop using an adaptor).
A clean should be carried out if a system is dirty – this will become clear as you will be experiencing problems like cold radiators, or a noisy central heating system.
CG1 be topped up yearly, when water is taken out of the system, or any new fresh water is introduced to the system. The UK guidelines, BS7593, also recommend the system be cleaned, drained and refilled, using CG1 Protector, every 5 years, whether water has been added/removed to the overall system or not.
No, overdosing the system is unlikely.
