2 Important information/Safety regulation
2.1 General safety precautions
Warning Risk of personal injury! Children are not permitted to play with the product.
Warning As the water temperature in Diplomat Optimum G2/G3 and Diplomat Duo Optimum G2/G3 becomes hot (up
to 95°C), a mixer valve must be installed between the cold water and hot water pipes to ensure a lower do-
mestic hot water temperature.
Alternatively the maximum hot water temperature must be reduced in the Service menu.
Caution 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.
Caution This product 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.
Caution The heat pump must be located in a frost-free environment!
Caution The heat pump must be placed in an area with a floor drain.
Caution The heat pump must be located on a stable base. The floor must be able to support the gross weight of the
heat pump with filled hot water tank (see Technical data).
Caution To prevent leaks, ensure that there are no stresses in the connecting pipes!
Caution It is important that the heating system is bled after installation.
Caution Bleed valves must be installed where necessary.
Caution The hot water tank must be equipped with an approved safety valve.
Installation Guide Domestic heat pumps
VMGFP202 Thermia Värmepumpar

Caution Heating systems with closed expansion tanks must also be supplied with approved pressure gauges and safe-
ty valves.
Caution Cold and hot water pipes and overflow pipes from safety valves must be made of heat resistant and corro-
sion-resistant material, for example copper. The safety valve overflow pipes must have an open connection to
the drain and visibly flow into this in a frost-free environment.
Caution 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.
N
If there is any risk of groundwater infiltration at wall lead-ins for brine pipes, watertight grommets must be
used.
N
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.
2.2 Refrigerant
2.2.1 Refrigerant
Caution 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.
2.2.2 Fire risk
The refrigerant is not combustible or explosive in normal conditions.
2.2.3 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.
Warning Risk of personal injury! Spaces in which heavy vapour can collect below the level of the air must be well venti-
lated.
Refrigerant vapour is heavier than air and, in enclosed spaces below the level of a door for example, and in the event of leakage, concen-
trations can arise with a resultant risk of suffocation due to a lack of oxygen.
Warning Risk of personal injury! 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.
Installation Guide Domestic heat pumps
Thermia Värmepumpar VMGFP202 7

2.2.4 Work on the refrigerant circuit
Caution When repairing the refrigerant circuit, the refrigerant must not be released from the heat pump, it must trea-
ted in the appropriate way.
Draining and refilling must only be carried out using new refrigerant (for the amount and type of refrigerant see manufacturer’s plate)
through the service valves.
Caution All warranties from Thermia are void if, when filling with refrigerant other than Thermia Värme AB specified
refrigerant, if there has not been written notification that the new refrigerant is an approved replacement re-
frigerant together with other remedies.
2.2.5 Scrapping
Caution When the heat pump is to be scrapped the refrigerant must be extracted for disposal. Local rules and regula-
tions related to the disposal of refrigerant must be followed.
2.3 Electrical connection
Warning Hazardous electrical voltage! The terminal blocks are live and can be highly dangerous due to the risk of elec-
tric shock. All power supplies must be isolated before electrical installation is started. The heat pump is con-
nected internally at the factory, for this reason electrical installation consists mainly of the connection of the
power supply.
Caution Electrical installation may only be carried out by an authorized electrician and must follow applicable local
and national regulations.
Caution 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).
2.4 Water quality
Caution A normal heating system always contains a certain amount of corrosion particulates (rust) and sludge prod-
ucts from calcium oxide. This comes from acid that is naturally occurring in the fresh water that the system is
filled with. It is not good practice to have to fill the heating system regularly which is why any leakage in the
heating system should be repaired immediately. Normal filling should occur only once or twice a year. The
water in the heating system should be as clean as possible, always position the dirt filter on the return line
from the heating system to the heat pump, as close to the heat pump as possible.
Caution Hard water; Normally it is not a problem installing a heat pump in areas with hard water because the normal
operating temperature for the hot water does not exceed 60°C. In areas where there are exceptional prevail-
ing conditions with the water one can install a softening filter, which softens the water, cleans any impurities
and prevents the build up of calcification.

2.5 Commissioning
Caution The installation may only be commissioned if the heating system and brine system have been filled and bled.
Otherwise the circulation pumps can be damaged.
Caution If the installation is only to be driven by the immersion heater during the installation, ensure that the heating
system is filled and the brine pump and compressor cannot be started. This is carried out by setting the oper-
ating mode to AUX. HEATER.

3 Transport, unpacking and setting-up
3.1 Transporting the heat pump
Caution During transportation or lifting of the entire heat pump, the front panel must always be installed as it locks
the other panels construction.
Caution The heat pump must always be transported and stored in a dry area. Secure the heat pump so that it cannot
tip over during transportation.
Caution The heat pump must always be transported and stored standing and in a dry environment. If the heat pump is
laid on the incorrect side it may become seriously damaged as the oil in the compressor can run out in the
pressure pipe and therefore prevent normal function.
When transporting indoors to the installation location it may be necessary to place the heat pump on its back. The time that the heat
pump is transported on its back should be as short as possible. After the heat pump has been lifted up again it must stand upright for at
least an hour before commissioning.
3.2 Unpacking
3.2.1 Unpack the heat pump
1. Check that there is no transport damage.
2. Remove the packaging.

3.3 Setting-up the heat pump
3.3.1 Recommended location
Caution To avoid condensation problems for the brine lines, as short a brine line as possible is recommended indoors.
The heat pump should be located on a stable floor, preferably made of concrete. When locating the heat pump on a wooden floor this
should be reinforced to take the weight of the heat pump including a filled water heater, see technical data for relevant heat pump. One
solution is to place a thick metal plate, at least 6mm, under the heat pump. The metal plate should cover several joists spreading the
weight of the heat pump over a larger area. If the heat pump is being installed in a newly-built house, this has normally been taken into
account during construction, and the joists where the heat pump will be located have been reinforced. Always check that this has been
carried out when installing into a newly-built house.
Avoid positioning the heat pump in a corner as the surrounding walls may amplify its noise. It is also important to adjust the heat pump
using the adjustable feet so that it is horizontal to the base.
3.3.2 Space requirement
Caution The heat pump must not be enclosed as the temperature inside the cabinet becomes extremely high.
To facilitate the fitting, installation and subsequent testing and maintenance there must be sufficient free space around the heat pump
in accordance with the following dimensions:
300 mm

3.3.3 Setting up
N
The heat pump has feet that can be adjusted to compensate for irregularities in the surface on which it is
sitting. If the surface is so irregular that the feet cannot compensate for it, the installation engineer must rem-
edy this.
N
It is recommended that the condensation drain is installed from the drip tray’s drain pipe by lying the heat
pump down. The drain pipe opens through a hole in the base plate and has a Ø10 mm hose connection.
N
If the heat pump has been laid down it is recommended that it stands upright for at least an hour before
commissioning.
3.3.4 Removing the front cover

er is removed!
1. Press against the front cover and turn the catch 90° degrees anti-clockwise to release the front
cover.
2. Tilt the front cover outwards.
3. Lift the front cover upwards to remove it from the heat pump.
3.4 Setting-up the outdoor unit
3.4.1 Recommended location
When positioning the outdoor unit, note the following:
Caution When the outdoor unit is defrosting, water will drip straight down under the unit. The area around the out-
door unit must therefore be properly drained in order to take the water (approximately 6 litres per defrost).
Caution The outdoor unit must be positioned on a secure base such as wooden sleepers, paving slabs or cast footings.
N
The outdoor unit does not have to be positioned in any specific direction.
N
Position the outdoor unit to reduce noise disturbance in your own home as well as to any neighbours.

5 Piping installation
Warning As the water temperature in Diplomat Optimum G2/G3 and Diplomat Duo Optimum G2/G3 becomes hot (up
to 95°C), a mixer valve must be installed between the cold water and hot water pipes to ensure a lower do-
mestic hot water temperature.
Alternatively the maximum hot water temperature must be reduced in the Service menu.
Caution Piping installation must be carried out in accordance with applicable local rules and regulations. The hot wa-
ter tank must be equipped with an approved safety valve.
Caution To prevent leaks, ensure that there are no stresses in the connecting pipes!
Caution It is important that the heating system is bled after installation. Bleed valves must be installed where necessa-
ry.
N
Ensure that the pipe installation is carried out in accordance with the dimensions and connection diagrams.
N
Configure the heat pump for the desired system solution in the SERVICE\ADD. HEATER\EXTERNAL ADDITION
menu.
5.1 Safety valves
Warning Radiator systems with a closed expansion tank must also be equipped with an approved manometer and
safety valve, minimum DN 20, 1.5 bar opening pressure, or according to country specific requirements.
Warning Cold and hot water pipes and overflow pipes from safety valves must be made of heat resistant and corro-
sion-resistant material, e.g. copper. The safety valve overflow pipes must have an open connection to the
drain and visibly flow into this in a frost-free environment.
Warning 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.
