Safety notice
Never perform any cleaning operations before switching off the external isolator
Do not modify safety or control devices without consultation with the manufacturer
Do not pull, detach or twist the electrical cables coming from the unit
Do not introduce pointed objects through the grill and into the fan.
Important Notice for Antifreeze to Avoid heat pump broken
1. Water flow switch MUST be installed during installation for heat pump air conditioning side to ensure
proper water flow.
2. Water filter MUST be installed before water go into PLATE HEAT EXCHANGER. The water filter need to
be cleaned at least half an year.
3. Must use enough brine(glycol) in the water system in cold area. if the air temp is lower than -0 ℃, for
the safety, you must use brine(glycol) as the fluid in the heat pump water system instead of pure water.
4. MUST keep the electricity power supply always connected even when you don't use the heat
pumps. Our heat pump has antifreeze function if with electricity connected. So If without enough glycol
(antifreeze liquid) and if the electricity is cut off by accident for more than 30 minutes in winter, you need to
drain out all the inside water to protect the heat pump to be frozen.

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.
2. SYSTEM DESCRIPTION
The AH9/11/16 is a monoblock (single unit) air/water heat pump, specially designed for the
colder climate. There is no need for bore holes and usually the system can be installed within 1
day.
The AH9/11/16 can both heat hot water effectively at high outdoor temperatures and give a
high output to the heating system at low outdoor temperatures. If the outdoor temperature
drops to a level lower than minus 0℃ (factory setting), the auxiliary heater switches on to
ensure the heat pump unit works normally. The unit is also capable of cooling in the summer.
The heat pump controller is an intelligent wired system.
The AH9/11/16 is rated as 9KW/11KW/16KW. The Material/components are chosen to
provide a long service life and to fully withstand harsh outdoor conditions.
AH9/11/16 has two different installation options:
1). Space heating/cooling + DHW (Domestic hot water)
2). Space heating/cooling only or DHW only
3. INSTALLATION
3.1: General points for installation engineer
3.1-1: Transport and storage
The unit should be transported and stored vertically.
3.1-2: Inspection of the installation
Current regulations require the heating installation to be inspected before it is commissioned .
The inspection must be carried out by a suitably qualified person and should be documented.
- 4-
If the heat pump is replaced, the installation must be inspected again. In the event of
installation with unvented (closed) heating systems, G3 unvented guidelines must be
followed during the install. It should be noted that the heat pump provides the first measure of
defense against high pressure/temperatures. A further 2 must be installed to comply with the
G3 unvented procedures.
3.1-3: Siting the heat pump
The unit is placed (securely fixed) outdoors on a firm base, preferably a concrete foundation. It
should not be positioned next to sensitive walls, for example, next to a bedroom. Also ensure
that the placement does not inconvenience any neighbours’.
Large amounts of condensation water as well as de-icing water from defrosting can be
produced. You must provide good drainage at the installation area and make sure the water
cannot run out onto paths or the like during periods that ice can form. Ideally, condensation
water is led off to a water drain or a suitable soak away. The distance between the unit and the
exterior wall must be at least 350 mm. The free space above must be at least one meter. The
unit must not be placed in a position so that air can re-circulate thus lowering the COP.
Care must be exercised so that the heat pump is not scratched during installation.
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.
The number of starts and the operating time can also be read.
The controller is set during installation and can be used during a service.
Under normal operating conditions the home owner does not need to have access to the
controller. The AH9/11/16 has an integrated electronic outlet water temperature sensor that
limits the outlet temperature up to 60℃.
3.2 Installation design
The AH9/11/16 can be installed in several different ways.
- 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.
A) Space Heating/Cooling + DHW
B). Space Heating/Cooling Mode Only
C) .2x 8/16/16 Installation. Space Heating/Cooling + DHW
- 6-
D). 3X8/11/16 Installation. Space Heating/Cooling + DHW.

3.3 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.
- 8-
All outdoor pipes must be thermally insulated with at least 19 mm thick pipe insulation. The
insulation must also be vapor resistant.
The water circulation pump must at all times be operational (even if AH9/11/16 is not running)
to prevent any possible damage due to freezing. Even when in standby mode, the circulation
pump is controlled directly from the 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.
The supplied flexible hoses act as vibration dampers. The flexible hoses are fitted so a slight
bend is created, thus acting as vibration dampening.
Important: Even though the AH9/11/16 has anti-freeze protection, if the circulation pump
fails or there is a problem with the power supply, there is still a risk of damage due to freezing.
During the installation Anti-freeze (Ethylene Glycol) is strongly
recommended. If the air temp is ever lower than 0c, it must use enough
glycol.
3.4 Electrical Connection
Electrical installation and service must be carried out under the supervision of a qualified
electrician. Electrical installation and wiring must be carried out in accordance with the
stipulations in force.
