PRODUCTS DESCRIPTION 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. ALTO 1.Outdoor unit Evaporator Fan and fan motor Handle valve 2.Indoor unit EVI scroll compressor EVI plate heat exchanger Expansion valve Water pump Pressure balance valve Handle valve Auxiliary electric heater Safety equipment for refrigerant system Electric components (If the electric heating element is turned on)
until If the water temperature is not acchieved after heat pump heating for 30 minutes, electric heater is turned on to assist the heating till the targeted temperature is reached
There are two sets 5 metre copper pipes in the accessary kits to connect the outdoor and indoor unit. 4
Venting venting valve
Open the pump electric cover by screwing, fix the terminals according to the schematic symbols.

Phase protection
1.Change the locating of any two phase 2.Check the voltage between phase wire
Er09
System malfunction protection
Check the refrigerant system
Er10
Whole system Flow lack or flow switch problem
1.Make sure there is no air in water circulation system 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
Er11
Tank Flow lack or flow switch problem
Er12
High pressure protection
Er13
Low pressure protection
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 1.Check the temperature difference between inlet and outlet 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. 1.Check whether there is any ice around the heat pump 2.Check whether the fan of heat pump is working
