Cooling Tower Water Conditioning - Installation and Operation Instructions:

Installation: The installation of AQUA CORRECT system is performed into the water supply pipe. The AQUA CORRECT capacity type shall be selected for full conditioning of the maximum water flow. There is no demand to flow direction, horizontal or vertical installation. The draining outlet pipe from the cooling tower must be connected to the lowest point of the water tank and the size of the pipe must secure effective removal of impurities, (min. 1 1/4" pipe) with fall toward ground.

The draining shall be valve controlled by the installation of a conductivity sensor connected to an automatic processor (range: 0 to approx. 2000 m Siemens/cm) with upper and lower output limits.

Operation instructions: The draining of upconcentrated mineral salts and impurities is an integrated part of the treatment procedure and performance guarantee. It is depending on the amount of evaporated water and the water hardness. The conductivity in the water shall normaly not exeed the value of 1200 m Siemens/cm (approx. 37 0dH = 660 ppm).

In accordance with the American CTI-standard (USA) and the equal German VDI-DIN 1947- recommandations shall, in relation to evaporated water (Wwo), a constant sufficient draining of the upconcentrated minerals (Wwa) follow and be replaced by new conditioned water (Wwz). The recommended values are:

-Wwo: 0,15 x K (cooling area) x V (amount of water) /100 = m³/h for open circuits.

-Wwo: 3,60 x Q (cooling effect kW) /2500 = m³/h for closed circuits.

-Wwa: = Wwo (max. standard value, but depending on the concentration velocity)

-Wwz: Wwa+ Wwo = m³/h (generel, + or ^- % local depending)

IMPORTANT!

The physical AQUA CORRECT conditioning of the water supply replaces the use of all softening units and previously chemical dossage. In case of chemical use for removal of algea, the dosage may be reduced in accordance with the 8-10% reduced water surface tension. If using chemicals, any reactions, disposals or corrosion is the responsibility of the supplier of the chemicals only. Replace all water and use only AQUA CORRECT system conditioned water at first time start up!

Static voltage tension potencials, f. inst. frictional electricity by the use of PVC tubes, may cause lime disposals in all systems and are excluded from the treatment guarantee.

WORKING CONDITIONS

During the disolving of existing disposals it shall be expected that loosen substances, which can not pass through nozzles, repeated must be removed manualy. Dissolved substances may increase the pH values and form impurities on the conductivity sensor electrodes. Regular control of the electrodes and the draining function is required according to local conditions.

GUARANTEE

The performance guarantee is related to above conditions being followed. The AQUA CORRECT guarantee is valid for the described function for a period of 6 month, provided duly payment of the AQUA CORRECT system supplied. The material substaining guarantee is 5 years.
