Combiguard

If unchecked, limescale, resulting from hardness salts in the supply water, will cause damage and loss of efficiency in heat exchangers. Scale will build up gradually until the pipework and exchanger become blocked. There may then be difficulty reaching the required hot water temperature and flow to service points. Additionally, washing machines, dishwashers, hot water cylinders and other storage vessels will also suffer. Because the efficiency of the heat exchanger will be impaired, this will inevitably result in extra fuel consumption by the boiler.

The solution is to install Sentinel Combiguard.

Ideal for Use With:

Combination Boilers
Thermal Storage Systems
Unvented Hot Water Systems
Electric Showers
Boilers and Pipework
Multi Point Heaters
Hot Water Cylinders
Washing Machines and Dishwashers

Important Note

To ensure safe, on-going scale protection, the cartridge must be replaced yearly or sooner if the annual usage of water exceeds 120,000 litres.
Sentinel Combiguard is a food grade product.

Location

Note: Installations of the Sentinel Combiguard Scale Inhibitor should comply with Local Water Authority regulations and bylaws. In some areas a non-return valve may be required. The kitchen cold water tap and the outside tap should be left untreated.

The Sentinel Combiguard Scale Inhibitor can be simply installed into horizontal, vertical or any angle copper pipe. There must be a minimum of 450 mm pipe between the outlet of the Sentinel Combiguard and the inlet of a boiler/heat source. The cartridge must always be in the vertical position. Adapters are available to join to other types of tubing. If in doubt consult your supplier. The water flow must be in the direction of the arrow embossed on the body of the tee piece.

A wall bracket plate is built in and should be used where pipework will not adequately support the unit.

Further Technical Installation sheets are available on request.
