4 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 and valves). 2

10 BUTTON EXPLANATION Before switching on the unit press this button for 5 seconds to turn on the user s setting function. Press this button for 10 seconds to turn on the manufacture parameter setting function. After switching on the unit. Press this button for 5 seconds to set heater manually or heater automatically just press transienctly to select heater consumption. Press shortly to switch water tank temperature setting and room temperature setting. The room symbol will appear on the screen when enter room temperature setting. Press for 5 seconds to get into manually protection against legionella flashes on the screen function it can get into the consulting for current running status checking press for 5 seconds to enter manual defrosting function 8

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 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 12
