NON-SERVICEABLE CRITERIA

TURN OFF POWER SUPPLY, then please consult an authorized dealer under the following conditions:

• Abnormal noise during operation. • Water/foreign particles have entered the control panel. • Water leaks from the indoor unit. • Circuit breaker switches off frequently. • Power cord becomes unnaturally warm.

The following symptoms do not indicate malfunction.

SYMPTOM	CAUSE
Flowing sound during operation.	Refrigerant flow inside the unit.
Operation is delayed a few minutes after restart.	The delay is a protection to the unit's compressor.
Outdoor unit emits water/steam.	Condensation or evaporation occurs on pipes.
Outdoor unit emits steam during heating mode.	This is due to defrost operation happens at the heat exchanger.
Outdoor unit does not operate.	When the outdoor temperature is out of the operation condition range, the heatpump system enter protection control.
Air-to-Water Heatpump system operation will turn off.	If indoor unit water inlet temperature is lower than 20°C. Backup heater power will turn on to heat up the water.
System difficult to heat-up.	When heating is operated by indoor unit together with floor heating or panel heater simultaneously, there may be case where warm water temperature is getting lower and cause floor heating or panel heater heat-up is weaken.When outdoor air temperature is low, it may be difficult to get warm.Is the snow pile blocking the discharge outlet or intake inlet of outdoor unit.When water outlet set temperature is low, it may be difficult to get warm.
System cannot get warm instantly.	Due to the nature of the heatpump system, it may take some time to heat-up the water if the unit is operated from cold-start.
Operation starts after power resumes.	Unit is operates under auto restart function.

Check the following before calling for servicing.

SYMPTOM	CHECK
Heating/cooling operation is not working efficiently.	Set the temperature correctly.Is the panel heater/cooler valve closed.Clear any obstruction at the air inlet and air outlet vents of outdoor unit.
Noisy during operation.	Check if the unit has been installed at an incline or the cover is not closed properly.
The unit does not work.	Check if the circuit breaker is tripped.
Operation LED is no lit or control panel display is blank.	Is the power supply off or power failure.
