Engineer Training Cooler TJ8300 / TJ8500 Confidential 2 Introduction

Engineer Training Cooler TJ8300 / TJ8500 Confidential 3 Location Located inside the collecting table

Engineer Training Cooler TJ8300 / TJ8500 Confidential 4 General Description  The cooler is located inside the collecting table.  The cooler’s function is to cool the water that flows through the UV lamp head.  The ambient temperature should be 15°C - 35°C.  The water circulates through the UV lamp head and the cooler.  The water flow pressure is bar.  Within the cooler, the distilled water flows from the water container, through the radiator, which cools it, and then is pumped towards the UV lamp head.

Engineer Training Cooler TJ8300 / TJ8500 Confidential 5 General description (Cont.)  The fan in the cooler removes the heat.  The water temperature must be below 70°C. Otherwise, the lamp will be turned off.

Engineer Training Cooler TJ8300 / TJ8500 Confidential 6 Cooler Unit Components The cooler unit includes:  Water container  Two Radiators  Water pump  Water pipes  Temperature sensor  Water filter  Cooler panel

Engineer Training Cooler TJ8300 / TJ8500 Confidential 8 Water Container (Cont.)  The water container contains 50 liters of distilled water with 0.5% of corrosion inhibitor and 1 unit of microtreat.  The water circulates through the cooler and the UV lamp head.  The purpose of the water (float) sensor is to alert the system if the water level is low.  If the water reaches the low (threshold) level, the system turns off the lamp power. Corrosion inhibitor

Engineer Training Cooler TJ8300 / TJ8500 Confidential 9 Radiators  The purpose of the radiators is to cool down the warm water that returns from the UV lamp head.  The fan removes the heat from the cooler unit.

Engineer Training Cooler TJ8300 / TJ8500 Confidential 11 Water Pump (Cont.)  The pump circulates the water through the UV lamp head and the container, via the two radiators.  The thermal switch is set to 70°C and protects the system against high temperatures. If the temperature of the inlet water (into the radiators) reaches 70°C, the system turns off the UV lamp.  The water flow pressure is bar.

Engineer Training Cooler TJ8300 / TJ8500 Confidential 12 Water Tubes Two water tubes are connected between the UV lamp head and the cooler unit. Red mark: The tube carries heated water from the UV lamp head to the cooler unit. Blue mark: The tube carries cold water from the cooler unit to the UV lamp head.
