(If the electric heating element is turned on)
There are 7 models for Alto ALH/S series(EVI-Enhanced vapour injection
technology) heat pump range. They are AHH-R075/ALH, AHH-R100/ALH,
AHH-R120/ALH,AHH-R140/ALH, AHH-R160/ALH, AHH-R220/ALH,
AHH-R280/ALH. Heat is distributed throughout the house over a hydronic
heating system with outlet water temperature of 65℃. Most of the heating
demand is taken care of by the heat pump.

Phase protection
1.Change the locating of any two phase
2.Check the voltage between phase wire
Check the refrigerant system
1.
2.Check the venting valve and venting valve seal ring
3.Check the main circulation pump
4.Open the venting valve to exhaust air
5.Check the main circulation pump be sure the pump is
operating well
Make sure there is no air in water circulation system
1.Check the water tank to make sure it’s full of water
2.Make sure the venting valve is sealed and no air in
the water tank

of heat pump
2.See that the thermostats are open in the radiators or
the floor heating. More than the half of them must be open
to the whole position.
3.Check the filter(water) and clean it if it some dust in it.
4. Check if it is air in the water system. remove from the vessels.
Check the temperature difference between inlet and outlet
1.Check whether there is any ice around the heat pump
2.Check whether the fan of heat pump is working
