Mono bloc Unit In case of a power supply failure or pump operating failure, drain the system (as suggested in the figure below). When water is idle inside the system, freezing up is very likely to happen which could damage the system. • 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 mono bloc unit so that the snow does not cover the air inlet and air outlet vents. H

• Clean the external filter at least once a year. Failure to do so may cause the filter to clog up, which may lead to system breakdown. Consult an authorised dealer.

• In order to ensure optimal performance of the units, seasonal inspections on the units, external filter and field wiring have to be carried out at regular intervals. Consult an authorised dealer about maintenance.

• Clear any obstruction on the air inlet and outlet vents of the mono bloc unit.

Disconnect the power supply then please consult an authorised dealer under the following conditions:

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

For extended non-use

• Do not switch off the power supply. Switching off the power supply will stop the automatic water pump operation and will cause jamming in the water pump.

The following symptoms do not indicate malfunction. Symptom Cause

System is hard to heat up.

System does not heat up instantly.

• Condensation or evaporation occurring in the pipes.

• It is caused by defrost operation in the heat exchanger. • It is caused by the protection control of the system when outdoor temperature is out of the operating range. • It is caused by the protection control of the system. When the water inlet temperature is lower than 10 °C, the compressor stops and the backup heater power turns on. • When the panel and the floor are heated simultaneously, warm water temperature may decrease, which may reduce the heating ability of the system. • When the outdoor air temperature is low, the system may need longer time to heat up. • Discharge outlet or intake inlet in the mono bloc unit is blocked by some obstacle, such as a pile of snow. • When the preset water outlet temperature is low, the system may need longer time to heat up. • System will take some time to heat up the water if it starts to operate at cold water temperature. • It is caused by the protection control of the unit heat exchanger.
