- Do not press or hit the glass cover with hard, pointed objects. This may damage the unit.

- Ensure that the water pressure is between 0.05 to 0.2MPa.

- In case the water pressure is out of the above range, please consult authorized dealer.

INDOOR UNIT & CONTROL PANEL

• Do not splash water directly.
• Wipe the unit gently with a soft, dry cloth.

EXTERNAL FILTER

- Please clean the external filter at least once a year. Fail to do so might cause filter clogged, consequent system breakdown. Please consult authorized dealer.

OUTDOOR UNIT

• Do not obstruct the air inlet and air outlet vents, it may cause low performance or breakdown. Please remove obstacles to assure the ventilation.
• During winter, please clean and remove the snow near outdoor unit so that the snow does no cover the air inlet and air outlet vents.

INSPECTION

• In order to ensure optimal performance of the unit, seasonal inspections on the unit, external filter and field wiring have to be carried out at regular intervals. This maintenance should be carried out by authorized dealer.
• Clear any obstruction at the air inlet and air outlet vents of outdoor unit.

FOR EXTENDED NON-USE

- Turn off the power supply.

NON SERVICEABLE CRITERIAS

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

• Abnormal noise during operation.
• Water/foreign particles have entered the control panel.

• Power cord becomes unnaturally warm.

TROUBLESHOOTING

The following symptoms do not indicate malfunction.

SYMPTOM

Flowing sound during operation.

Operation is delayed a few minutes after restart.

Outdoor unit emits water/steam.

Outdoor unit emits steam during heating mode.

Outdoor unit does not operate.

Air-to-Water Heatpump system operation will turn off.

System difficult to heat-up.

System cannot get warm instantly.

Operation starts after power resumes.

CAUSE

Refrigerant flow inside the unit.

The delay is a protection to the unit's compressor.

Condensation or evaporation occurs on pipes.

This is due to defrost operation happens at the heat exchanger.

When the outdoor temperature is out of the operation condition range, the heatpump system enter protection control.

If indoor unit water inlet temperature is lower than 20°C.Backup heater power will turn on to heat up the water.

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.

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.

Unit is operates under auto restart function.

Check the following before calling for servicing.

SYMPTOM

Heating operation is not working efficiently.

Noisy during operation.

The unit does not work.

Operation LED is no lit or control panel display is blank.

CHECK

Set the temperature correctly.Is the panel heater valve closed.Clear any obstruction at the air inlet and air outlet vents of outdoor unit.

Check if the unit has been installed at an incline or the cover is not closed properly.

Check if the circuit breaker is tripped.Is the power supply off or power failure.

The operation LED blinks and error code appear on control panel display.
