  • Page 15   Symptom  : In HEAT Mode, indoor unit is blowing cold air instead of heating.  Reason   : Missing wire connection, defective reversing valve actuator.  Solution  : Otherwise, assure that the YELLOW wire is attached to terminal #3 on the outdoor unit. Also  check  that  the  same  yellow  wire  is  either  connected  to  the  #3  terminal  on  the  indoor  unit  (009,  012,  018  models) or the white plug at the end of the cable at the indoor side is plugged with the matching white plug on  the  indoor  unit  properly  (for  024  models  only).  While  in  Heat  Mode:  Check  for  voltage  between  #3  and  N  terminals on 115V models and assure it reads 115V or check between #3 and L2 terminals on 230V models and ...
  • Page 16 Symptom  : Water dripping from the indoor unit.  Reason   : Misaligned installation leveling, blocked drain tube, frozen coil.  Solution  : Check that the indoor unit is installed in a perfectly horizontal position. Check that the end of  the drain hose is dripping water properly on the outside. Check that the drain tubes are not kinked, blocked or  siphoned.  Assure  that  the  drain  hose  stays  as  low  as  possible  in  the  wall  hole  and  has  a  continual  proper  declination in its level. Check the evaporator coil if frozen. This can be the indication of refrigerant loss from the  system.  Check  and  assure  correct  operating  pressures.  Check  for  kinks  in  copper  lines.  Always  close  all  open  windows and doors to avoid excessive humidity entering the room. ...
  • Page 17 Symptom  : System does not automatically restart after a power failure.  Reason   : Auto Restart Function has been turned OFF.  Solution  : Turn OFF the breaker, Press and hold the emergency restart button and turn the breaker ON  while  still  holding  the  button  pressed  for  10  more  seconds.  5  beeps  indicate  activation  of  the  Auto  Restart  function. Repeat the procedure for tuning OFF the auto restart function in not desired (Indicated by 3 beeps).    Symptom  : Indoor unit blows smelly air.  Reason   : Dirty filters and/or evaporator coil.  Solution  : Clean the filters. If the coil is dirty have the evaporator professionally cleaned. Run the unit for  several hours in FAN ONLY mode to dry it before preparing to leave the system OFF for long periods of time.    Symptom  : Uncomfortably wide temperature swings in the room.  Reason   : Indoor unit installed too high, filters dirty, Room temperature sensor deficiency.  Solution  : Higher locations in the room will have warmer temperatures and the system will measure the  temperature at the height the indoor unit is installed. User can compensate for this by setting the temperature ...
