Page 4: Safe Electrical Working Practices
Safe Electrical Working Practices Remove Power cord, Fuse or Switch off the circuit breaker. Always check appliance with multimeter to ensure the supply power is disconnected. Use only insulated tools & equipment. Wear insulated shoes. No water on the floor or working space. Reduce the amount of exposed skin, by covering your arms and legs. -
Page 5: Capacitor Discharge
Capacitor Discharge Discharge the capacitors located on the outdoor main PCB assembly. Note: Even if the power supply has been disconnected, high voltage power can be stored in these capacitors. Discharge the capacitors with the use of a 25 or 40-Watt incandescent globe. As illustrated below. Electrolytic Capacitors Bulb (25-40W) Page 5 KSSSI113... -
Page 6: Led Flash Code Sequence Description
LED Flash Code Sequence Description (Indoor Display PCB) # In the event of a complete shutdown or an operational control adjustment the Standby, Heating or Cooling LED’s on the indoor display PCB flash to indicate this sequence. Note: The LED’s flash at a 1 second rate for the required number of flashes, and then a 2 second pause before repeating the 1 second rate sequence. -
Page 7: Led Flash Code Sequence Description
LED Flash Code Sequence Description (Outdoor PCB) # In the event of a complete shutdown or an operational control adjustment the outdoor PCB Green, Yellow & Red LED’s flash to indicate this sequence. Note: The LED’s flash at a 1 second rate for the required number of flashes, then a 2 second pause before repeating the 1 second rate sequence. -
Page 8: Not Operating
Not Operating: # Check the wiring configuration from the outdoor unit to the indoor unit. Is it wired up correctly in accordance to the wiring diagrams provided on both indoor & outdoor units? (Refer pages 29 to 31) # While the unit is in “standby” mode, check if the red stand by light is on? # Try operating the unit by the forced operations button: By pressing the button once, the unit should activate in Auto mode. -
Page 9: Not Operating
Not Operating Continues # Check for supply voltage at the following connection points: From the isolation switch to the Active-In & Neutral connector points located on the indoor PCB. If supply power is available at the above connector points, yet the unit can still not be operated by the remote control or the forced operation button, replace the indoor PCB. -
Page 10: Diagnostic Display Mode Description
Diagnostic Display Mode Description: Built into the software for models: KSV26HRC & KSV35HRC are two different diagnostic methods: (Fault Codes & Condition Codes) that can be used to help diagnose various faults. These two diagnostic types are described in the following pages. - Page 11 Fault Code Description Continues: E8, Indoor Unit. (Delayed) Indoor Standby LED, flash 8 times. (Delayed) Red LED, Outdoor unit flashing 3 times. (Anti-High Temperature Protection) # Check the indoor coil for airflow obstructions. # Check the indoor fan motor for correct operation. H1, Indoor unit.
- Page 12 Condition Code Description: D1, Indoor unit - (Condition Code) DRED (Demand Response Electrical Device) # Compressor off. D2, Indoor unit - (Condition Code) DRED (Demand Response Electrical Device) # Output capacity limited to 50%. D3, Indoor unit - (Condition Code) DRED (Demand Response Electrical Device) # Output capacity limited to 75%.
