This upgraded version of the original CF30 incorporates two dump valves, so that fresh water can be forced at high velocity in either direction during the dumping process, purging contaminated water through the dump hoses to waste.

By this means, all parts of the system can be scoured by high velocity turbulent water, improving the efficiency of power flushing and reducing the job time. One single man can power flush a heating system in less than four hours, solving circulation and noise problems resulting from corrosion and sludge deposits.

The powerful flow, combined with an instantaneous flow reversing device, will dislodge and mobilise deposits and corrosion which resist traditional system cleaning methods. Radiators may be individually flushed in sequence, and the progress of the the power flushing process can be clearly seen at all times through the translucent tank.

With POWER FLUSH FX2 flushing and descaling liquid, the CLEARFLOW® DDV will completely flush and clean a system in just one service visit, with no need for an initial visit to pre-treat the system.

NOTE: The CLEARFLOW® CF30 pump is designed to allow hard flushing of a heating system with minimal dismantling. Generally, it is only necessary to remove either the system circulator pump, or alternatively one radiator for attachment of the CF30 to the heating system, although there are other possible attachment methods.Radiators may be individually flushed without removing or disconnecting them from the system.

The unit may be used with any commercially available chemicals currently in use for flushing and descaling heating systems, including strong acids or alkalis. Pumps with 220 volt motors are single phase, and may be used on a standard domestic 13 amp supply.

A 5 ampere fuse should be fitted in the plug top. We recommend the use of a residual current circuit breaker plug or adapter for extra protection.
