8- FAILURE LOCATION GUIDE EQUIPMENT WITH LOW EFFICIENCY Check: WATER PUMP PERFORMANCE AND ELECTRICAL CONNECTIONS a) Remove the upper cover. b) Remove the water hose from the evaporator. c) Using a container with a cm scale on it, turn on the pump and collect the water for one cycle, which should be between 800 cm (minimum) and 1500 cm3 (maximum). - Page 39 The restriction valve is not clogged and that water flows freely OUTLET CLOGGED (NO RESTRICTION) trough the outlet. The water pump supply voltage is correct: 9.8 V minimum. Important: Measure at the pump's connector with the pump working and the turbo blower at maximum speed. The water pump consumption (Amp) is between the specified values: between 3.7A and 6.0A (with water running through).
- Page 40 If the water collected is above the maximum, check that: (NO RESTRICTION) CLOGGED OUTLET The restriction valve is not clogged and that water returns freely trough the outlet. The switch commanding the water cycle is properly set. (See Water Cycle Setting before) EVAPORATOR ASSESSMENT Manually pull up the evaporator and with the water pump working, check that water is distributed evenly around the evaporator.
- Page 41 Verify that evaporator and air filter are not dirty or lacking wooden chips. Verify that electrical connections are rightly performed. Verify the biturbo blower input voltage: 9.5 V minimum. Important: Measure at the biturbo blower pins and when it is working and the water pump is working.
