- 3-

1 GENERAL

The unit 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 unit 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 unit 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°C (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 unit is rated as 8KW/12KW/16KW. The Material/components are chosen to provide a long

service life and to fully withstand harsh outdoor conditions.

The unit 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.

- 4-

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. 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 Sitting 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 neighbors’.

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.

- 5-

3.1-4 Controller

The unit 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 unit has an integrated electronic outlet water temperature sensor that limits the outlet

temperature up to 60°C.

3.2 Installation design

The unit can be installed in several different ways.

The safety equipment must be installed in accordance with current regulations for all installation

options.

When connecting with the unit, 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

- 6-

B) Space Heating/Cooling Mode Only

C) 2x8/12/16 Installation. Space Heating/Cooling + DHW

- 7-

D）3x8/12/16 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.

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 unit is not running) to prevent

any possible damage due to freezing. Even when in standby mode, the circulation pump is

controlled directly from the unit, 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 unit 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 unit 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.
