Page 4: Product Features
Touch sensor application Breaking away from traditional button applications, the Iguassu CT II has a built- in touch sensor ap- plication. This addition has been integrated into the already stellar system with customer convenience in mind. The easy-to-use sensor application allows for effortless and enjoyable drinking water. - Page 5 Function operations are designed as simply as possible in order to maximize convenience. Environment friendly coolant The Iguassu CT II has adopted an environmentally friendly cooling system in the new R-134a, a cool- ant that will not add to the problems of ozone layer destruction and global warming.

Page 17: System Malfunction Diagnosis & Repair Procedure
System Malfunction Diagnosis & Repair Procedure Table of Contents... - Page 18 11-1 POWER MALFUNCTION Symptom In case of LED display off although power connected. Detach top cover and right side cover, then find fuse holder. Check fuse inside the fuse holder if it is opened. > Replace fuse if it is faulty. Find transformer located at base plate of the unit then check its IN/OUT connection and voltage.
- Page 19 11-2 FILTRATION MALFUNCTION Check OLC and filtration process works properly. Check if there is water membrane on top of Mesh- OLC-S1 and medium filter area on the water tank. Check Membrane Check water supply valve is opened. Check wire connection of OLC and water level in the tube.
- Page 20 11-3 WATER DISPENSING (SOL V/V MALFUNCTION) Faulty water dispensing solenoid Valve (Hot/Cold/ Ambient) causes water dispensing malfunction. Check hot/cold/ambient water dispensing solenoid valves. - Check its voltage is DC24V supplies to Sol V/V at terminal when dispensing. > If not, replace Sol V/V - Check if there is leak of each Sol V/V.
- Page 21 11-4 HOT WATER MALFUNCTION If hot water overheated, ambient tank’s temperature goes up then it could causes overflow. Check electric resistance of hot water temp-sensor and manual bimetal. Hot water temp-sensor : Check electric resistance. (Refer page 25) Manual Bimetal : 105N (Off when 105°C) Check if hot temp-sensor is affixed properly onto hot water tank’s surface.
