    NOTE • The pressure drop in the duct will decrease the air flow rate, which will reduce the capacity of the unit. • Condensation may form on the outer surface of the ducts, harder in the exhaust air one. Be aware of this condition. We strongly recommend using thermally insulated ducts or thermally insulating the installed ducts.
  • Page 17 NOTE • The resistance of duct will decrease air-flow-rate, which will lead to capacity of unit decreased. • For the case of unit with duct, the duct total length should be no more than 5m , and the quantity of bending should be no more than 3.

    Depending on the degree of humidity in the air you can get up to 0,25l/h of condensation. The evacuation of condensate should not been made directly to sew water because of possible corrosive gasses damaging the exchanger fins and water heater parts. WARNING Do not block off the safety valve drainage pipe.

  • Page 37: Trouble Shooting

    8. TROUBLE SHOOTING Non-error tips Q: Why can’t compressor start immediately after setting? A: The unit will wait for 3 minutes to balance the pressure of system before starting compressor again. It's a self protection logic of unit. Q: Why dose the temperature shown on the display panel decreased sometimes while unit is running? A: When the upper tank temperature is much higher than the bottom part, upper part hot water will be mixed by the bottom cold water which is continually flow from inlet pipe so that will decrease the upper part temperature.
