The heat pump must be installed by authorised installation
engineers and the installation must follow the applicable local
rules and regulations as well as these installation instructions.
!
This apparatus is not intended for persons (including children)
with reduced physical, sensory or psychological capacity, or
who do not have knowledge or experience, unless supervised
or they have received instructions on how the apparatus
functions from a safety qualified person.
!
Children are not permitted to play with the apparatus.
!
The heat pump must be placed in an area with a floor drain.
!
The heat pump must be located on a stable base.
!
The base must be able to support the gross weight of the heat
pump when filled. (see Technical Specification)
ATTENTION!
Please make sure that all supply
lines are disconnected before attending any work to internal
electrical parts!
NOTE! To prevent leaks ensure that there are no stresses
in the connecting pipes!
NOTE! It is important that the heating system is completely
bled after installation.,
NOTE! Bleed valves must be installed where necessary.
l
Installation must be carried out in accordance with applicable
local rules and regulations. The hot water tank must be equipped
with an approved safety valve (supplied).
l
Radiator systems with a closed expansion tank must also be
equipped with an approved pressure gauge and safety valve,
minimum DN 20, for a maximum 3 bar opening pressure, or
according to country specific requirements.
l
Cold and hot water pipes and overflow pipes from safety valves
must be made of heat resistant and corrosion-resistant material,
e.g. copper.
l
The safety valve overflow pipes must have an open connection to
the drain and visibly flow into this in a frost free environment.
l
The connecting pipe between the expansion tank and the safety
valve must slope continuously upwards. A continuous upwards
slope means that the pipe must not slope downwards from the
horizontal at any point.
l
If there is any risk of groundwater infiltration at brine line lead-
ins, watertight grommets must be used, for more information see
Section 4.
l
In addition to applicable local rules and regulations the installation
should be carried out in a manner that prevents vibrations from
the heat pump being transmitted into the house causing noise.
!
Work on the refrigerant circuit must only be carried
out by a certified engineer!
Although the heat pump cooling system (refrigerant circuit) is filled
with a chlorine-free and environmentally-approved refrigerant that
will not affect the ozone layer, work on this system may only be
carried out by authorized persons.
Fire risk
The refrigerant is not combustible or explosive in normal conditions.
Toxicity
In normal use and normal conditions the refrigerant has low toxicity.
However, although the toxicity of the refrigerant is low, it can cause
injury (or be highly dangerous) in abnormal circumstances or where
deliberately abused. Refrigerant vapour is heavier than air and, in
enclosed spaces below the level of a door for example, and in the
event of leakage, concentrations can arise with a resultant risk of
suffocation due to a lack of oxygen. Spaces in which heavy vapour can
collect below the level of the air must therefore be well ventilated.
Refrigerant exposed to a naked flame creates a poisonous irritating
gas. This gas can be detected by its odour even at concentrations
below its permitted levels. Evacuate the area until it has been
sufficiently ventilated.
Anyone with symptoms of poisoning from the vapour must immediately
move or be moved into the fresh air.
Work on the refrigerant circuit
When repairing the refrigerant circuit, the refrigerant must not be
released from the heat pump – it must be destroyed at a special
plant. Draining and refilling must only be carried out using new
refrigerant (for the amount of refrigerant see manufacturer’s plate)
through the service valves. All warranties from Johnson Controls AS
are void if, when filling with refrigerant other than Johnson Controls
recommended refrigerant, it has not been notified in writing that the
new refrigerant is an approved replacement refrigerant together with
other remedies.
Scrapping
When the heat pump is to be scrapped the refrigerant must be
extracted for destruction. Local rules and regulations related to the
disposal of refrigerant must be followed.
Electrical installation may only be carried out by an authorized
electrician and must follow applicable local and national regulations.
!
The electrical installation must be carried out using permanently
routed cables. It must be possible to isolate the power supply
using an all-pole circuit breaker with a minimum contact gap of 3
mm. (The maximum load for externally connected units is 2A).
!
Electrical current!
The terminal blocks are live and can be
highly dangerous due to the risk of electric shock. The power
supply must be isolated before electrical installation is started.
The heat pump is connected internally at the factory, for this
reason electrical installation consists mainly of the connection
of the power supply.
!
NOTE! The room temperature sensor is connected to
a safety extra-low voltage.
Follow the separate installation instructions for the room
temperature sensor!

1.3 COMMISSIONING
1. IMPORTANT INFORMATION/
SAFETY REGULATIONS
!
The installation may only be commissioned if the heating
system, water heater and brine system have been filled
and bled. Otherwise the circulation pumps can be
damaged.
!
If the installation is only to be run on auxiliary heating, first
ensure that the heating system is filled and that neither the
brine pump nor the compressor can be started. This is
carried out by setting the operating mode to ADD.HEAT.
