4) The pump is running
◎
Exit condition (only need to meet any one of the below conditions)
1) When the heat pump is performing cooling mode / hot water mode;
2) When there is no demand for hot water or constant temperature control;
3) The water tank temperature sensor has a fault alarm;
◎
When it is under defrosting / forced defrosting / secondary antifreeze , the electric heating
is forced to turn on;
◎
When there is high-pressure failure / low-pressure failure / exhaust temperature sense
failure / excessive exhaust protection stop,and if compressor is locked and cannot be
started, then the electric heating will be started instead of the compressor after 5 minutes.

General Operating Guide
Initial Start-up Precautions
Fi
rst boot-strap and Running state checks
1. To ensure the power same as the product nameplate required power.
2. Unit electrical connections: Check if power supply wire track and connection is ok; if ground wire
is properly connected; Check if water pump and other chain device is properly connected
3. Water pipe and pipe: water pipe and pipe must be washed two and three times, ensure clean and
no any pollution.
4. Check water system: If the water is enough and no any air, ensure no leakage
5. First boot-strap or starting up again after long time stop, ensure power on ahead and heating at
least 12 hours for crankcase (local loop temp. is zero). Water pump start up first, last a while, fan
start up, compressor start up, unit regular work.
