The Fernox Injector has been designed to reduce the time involved in the introduction of treatments to both sealed and open vented domestic central heating systems.

With sealed systems the use of the Injector provides a quick and simple method of treatment not previously available.

With open vented systems, the main advantage of using the injector is to avoid continual access to the feed and expansion tank.

Application and Dosage

Treatment should be carried out when the heating system is off, i.e. cold and non-circulating. In order to treat a complete system, it is necessary to dose only one radiator.

Open vented systems are best treated by injecting into an upper floor radiator to minimise the opposing static head pressure.

Care should be taken to ensure that when the heating system has reached normal operating temperature there is sufficient capacity in the header tank to accept the additional treatment without causing overflowing.

It is recommended that a small quantity of Protector is added to the header tank after dosing, to provide sufficient biocide protection against bacterial contamination, slimes etc, in the tank.

Sealed systems must be treated in an un-pressurised condition, and if filled, provision must first be made by draining off an amount equivalent to the volume which is to be injected.

Always read the instructions supplied with the additive CAREFULLY before proceeding.
