Page 3: General
1. GENERAL The AH9/11/16 model is an air source heat pump for space heating and sanitary water heater for houses, apartment blocks and small industrial premises. Outdoor air is used as a heat source creating free energy to heat your home. - Page 4 3.1-4: Controller: The AH9/11/16 is equipped with an external electronic controller that handles all functions necessary for heat pump operations. Defrosting, stop at max/min temperature, connection of the compressor heater as well as enabling the aux electrical heater, monitoring of motor protection and pressure switches are all controlled.
- Page 5 The safety equipment must be installed in accordance with current regulations for all installation options. When connecting with the AH9/11/16, the total water volume in the heat pump pipe system and buffer tank must be at least 10 liters per KW of output.

- Page 7 Solar Application 3 (Most saving to use solar for space heating and DHW) Pipe Connection 28mm pipe is recommended. The pipe work must be flushed before the heat pump is connected, so that any contaminants do not damage the components parts. The heating/cooling water inlet and outlet direction must be connected according to the marked areas on the heat pump.
- Page 8 AH9/11/16, which takes the outdoor temperature and temperature in pipe into consideration to decide whether to circulate water within the system. Shut-off valves and drain valves are fitted so that AH9/11/16 can be emptied in the event of prolonged power failures.

Fill the system slowly ensuring bleed valves are open (if not automatic). 3.5-2: Inspection Before Start up Mechanical Inspection: a. Check the cabinet and inside pipe system for possible damage during transportation. b. Check that the heating water circuit is filled and well vented. Check the pipe system for leaks. c. - Page 12 When parameter P27= 0, E2 is AC heating control port, When parameter P27 = 1, E2 is 2 heat source control port d) DHW Auxiliary Electric Heater E1 When parameter P27 = ―1‖, When E2 not start, E1 will work as normal DHW assistant heater.

Page 23: Maintenance
Maintenance Maintenance and Cleaning for User It is good practice to inspect your heat pump regularly. Maintenance should be carried out at least annually to maintain a good lifespan of your heat pump. 1. Regularly clean the Y type filters every 6 months to ensure that the system is clean and to avoid blockage to the system. -
Page 24: How To Get The Most Out Of Your Heat Pump
How To Get The Most Out Of Your Heat Pump It is important to understand that you should operate heat pumps differently to conventional heating systems such as gas boilers. Below are some points you should be aware of: Since heat pumps produce water at a lower temperature (than gas boilers), it is important to remember the heat up time of your property is slower.
