Combimate limescale prevention device & Combiphos starter pack 22mm fittings

Part Number: COM2

Manufacturer: Cistermiser

Tried and tested – Combiphos is a polyphosphate compound specifically developed to provide the most effective limescale prevention in flow-through installations. Polyphosphate dosing has been safely used to treat water throughout the world for many years.

Note: Combiphos does not soften water and its effectiveness may be reduced in water heated to temperatures above 60 degrees, in water with carbonate hardness levels above 360 ppm or at pH levels below 6.5.

Combiphos is 100% food grade material approved by the FAO/WHO and compliant with the European normative standard BS EN 1208, that prevents scale build-up and soft water corrosion in combination boilers and other domestic hot water appliances.

Health and safety – Combiphos is tasteless and odourless and contains a polyphosphate compound which is classified by the WHO as a ‘food-grade’ additive. The quantity, size and hardness of the spheres control the amount of Combiphos released. Typically this is less than 3 ppm (parts per million) of phosphate in treated water and perfectly safe for human consumption.

There are two installations options when fitting Combimate: whole-house supply or single appliance protection.

Whole-house supply – For this installation Combimate should be plumbed in after the stop-valve on the cold water supply to the premises. The white removable divider tray should be removed from inside the Combimate dome in a whole house installation so that the dome can be completely filled with Combiphos (the full 800g bag contents).

Single appliance – Combimate can be used to protect a single appliance by placing it on the cold water supply to that appliance (e.g. a boiler), in which case the red removable divider tray should be left in place and Combiphos should only be put in the top half of the dome. This reduces the amount of Combiphos required for annual topping-up (in this situation, the 800g bag will last two years).

Combimate can be installed in various configurations, allowing maximum flexibility of pipework configurations.

Inlet and outlet connections use 15mm or 22mm compression fittings (depending on the model). There is minimal pressure or flow rate loss through Combimate. Vertical, top and bottom entry pipework can be used which ensures easy retrofit installation. Combimate should be installed at least 0.5 metre from any local sources of heat, such as boilers or hot water pipes.

A protective outer cover is fitted to complete Combimate installation.
