Product Description
Use
The Combi Blueline is a combined ventilation unit and
domestic water heat pump which can be used for:
• Air Heating
• Domestic hotwater;
• Ventilation with heat recovery;
• Air cooling both passively using the built in bypass and
actively using the heatpump
Description
The Combi Blueline is a unit that comes ready to connect
and consists of several important components, including
the cabinet, tank, refrigerant, ventilation unit, heatpump
as well as a control unit. The Combi is provided with a heat
exchanger built in to the domestic hotwater cylinder with
an area of 0.75 m2, enabling connection to external heat
sources such as a solar heating system. By using residual
heat in the extracted air, the Combi Blueline heat pump
can heat the supply air or produce domestic hot water.
Throughout the year, the Combi Blueline unit can provide
a family's hot water needs by heating domestic water.
The tank has a built-in immersion heater, and sensors
placed at the bottom and in the middle of the tank used
for temperature regulation in the tank.

5
DHW capacity
The Combi Blueline unit has the capacity to heat 185 litres
of domestic water to a temperature of 52°C within 8 hours,
but this may vary depending on factors such as the temper-
ature of the heat source, cold water and DHW tapping pat-
tern. To handle peak loads, an integrated electric immersion
heater with a 1 kW output is available. Compared to a di-
rectly heated tank, the Combi Blueline unit consumes only
about 30% of the electric energy.
The control unit (Optima 314) activates the compressor as
soon as hot water is used and the bottom of the tank cools
down, and it runs until the sensors detect that the entire
tank has reached the set temperature. The Combi Blueline
unit is capable of satisfying the hot water needs of an en-
tire family. In case of insufficient hot water production, the
immersion heater can be manually activated via the control
unit to produce double the amount of hot water. However,
using the immersion heater consumes more energy than the
compressor, so it should only be used during peak loads.
Heatpump process
The coolant circuit of the Combi Blueline is hermetically
sealed and uses R134a coolant as an energy carrier. The
heating module functions by removing heat from the air and
transferring it to the coolant via the condenser. The coolant
is compressed by the compressor and transported to the
domestic water heater and/or the supply air duct. The com-
pressor transfers energy into the coolant, which then heats
either the water or the air that requires heating. The cool-
ant then condenses and reverts to a fluid state.
Defrosting
When the temperature difference between the temperature
prior to the cooling coil and the temperature of the cooling
coil itself becomes too large, which occurs when there is ice
formed on the cooling surface, the unit will begin to defrost.
The supply air ventilator and the electric heating coils will
disengage. The discharge air ventilator will continue to run
together with the compressor, which will send hot gas direct-
ly into the evaporator until the ice melts and the cooling coil
reaches a temperature of around 5 °C, depending on the tem-
perature setpoint in the Optima314 controller. When the de-
frosting process has finished the supply air fan and the elec-
tric heating coil will re-engage balanced deicing mode where
the supply air fans run simultaneously with the extract air
fan is also possible but will increase the defrosting process.

INSTALLATION
Installation
The Combi Blueline unit should only be installed in premises
that are free from frost. The premises must meet certain
prerequisites, including a room temperature between 8 and
35 °C for operation using room air, condensate drainage, no
abnormal dust load in the air, and a solid foundation that
can take the total weight of the Combi Blueline when full of
water (400 kg). To ensure proper operation and allow for
repairs and maintenance, it is recommended to keep a
clearance of 0.6 m in front of the unit.
During installation, remove the packaging material, corner
protectors, and transport mounts from the pallet. Lift the
unit off the pallet and position it, then level it by turning the
adjustable support legs.
When setting up the product careful planning is advised in
relation to the position of any living room to avoid unsatis-
factory noise or vibration, which may occur due to the fans
and/or heat pump combined with unsuitable installation
conditions. It is recommended that the system is not in-
stalled immediately adjacent to a bedroom, and that it be
fastened to a heavy structure such as concrete. To prevent
sound or vibration transmission, anti-vibration materials
and soundproofing may be necessary in the installation
room.
The air used in the Combi Blueline unit should not be pollut-
ed with aggressive substances like ammonia, sulphur, or
chlorine, as these can damage the cooling system compo-
nents.
Connecting to a Water Mains
During installation, to ensure that there is sufficient pres-
sure and water where the water is drawn, take into consid-
eration the pipe dimensions in relation to the existing water
pressure and pressure loss.
The aspects of the installation that have to do with water
must comply with the local water supply regulations. The
water pipes to be used in the hotwater installation must be
approved for drinking water. Take into considera- tion the
corrosive properties of the materials used to avoid damage.
As with all pressurised containers, the tank of the unit must
be fitted with an approved safety valve and an approved
check valve on the supply side (always check the
local requirements).
The inflow of fresh cold water and the outflow of hot water
take place underneath the tank (3/4” RG connection). The
maximum operating pressure is 10 bar, and the maximum
operating temperature is 65 °C.
If necessary, the supply pipe must be fitted with a pressure
reduction valve and possibly with a filter.
When fitting the piping in the dwelling,
avoid contaminating the pipes. If required, flush
the pipes with clean water before connecting the
unit.
When fitting pipes, take care not to
twist the pipe connections. Use a pipe wrench to
apply counter pressure.
If recirculation is not used, make sure that the
recirculation pipe connection is fastened securely.
Due to the efficient cooling capacity of the
Combi Blueline unit , the supply air temperatures
can reach temperatures below the dew point
which in some cases may lead to condesate
forming outside the supply air ducts. It is
advised to insulate the supply air pipework
against condensation and/or to maintain a
suitable level of airflow that prevents the supply
air temperature to drop below the dew point

Connecting to Condensate Drain
A significant amount of condensate will form due to the
cooling of the air that passes through the heat exchanger.
The condensate drain from the supply and the extract air
side of the unit is fitted with hoses that can be looped to
form a condensate watertrap. The end of the hose will have
to be connected to a floor gully or a drainage system.
To ensure proper operation of the Combi unit, ensure that
the the two watertraps hold at lease 100 mm watercolum.
Ensure that the hose drops at least 1 % downward to the
drain to ensure sufficient draining of condensate.
Depending on air humidity, the amount of condensate
formed can reach 1 l/h.

Ducting System
To build an airtight and durable ducting system, we recom-
mend that the ducting system be made from spirally
flanged pipes using fittings with a rubber ring seal.
To keep the noise level from the unit satisfactorily low,
always mount silencers on the supply air and extract air
ducting systems between the unit and the first air intake
and extract valves.
To prevent the air intake and extract valves from generating
any noise, it is recommended that air speeds in the ducting
be kept sufficiently low.
Insulation of Ducts in Cold Spaces
To take advantage of the high heat recovery potential of the
unit (efficiency), it is necessary to insulate the ducts
properly.
Supply Air and Extract Air Ducts
To minimise heat loss from the ducting system in cold lofts,
insulate the supply air and extract air ducts with a minimum
of 100 mm insulation. If insulation form alternative (A) is
used, it is recommended that it takes the form of two lay-
ers of 50 mm lamella mats with paper or foil externally and
staggered joints between the two layers. If the ducts are
laid on the rafter foot, alternative B may be used. The insu-
lation must always be tightly packed around the ducts.
Fresh Air and Discharge Air Ducts
It is recommended that fresh air and discharge air ducts be
insulated with a minimum of 50 mm insulation followed by
aluminium foil. The fresh air duct is insulated to prevent
warm air in the loft from heating up the fresh air in the
summer.
To avoid condensation damage, make sure that the place
where the discharge air duct passes through the roof or the
gable end is sealed well.
When placing outdoor air and exhaust air hoods/gratings,
care must be taken not to short-circuit the two airflows,
thus causing exhaust air to avoid being sucked back in. It is
recommended that gratings be placed on the north or east
side of the house for optimal comfort in homes/ apart-
ments. Minimum distance: 3 or 1 meter depending on
orientation of the grates Ensure that the fresh air intake is
not affected by sun heating of roof and fresh air intake..
Please refer to drawing
Refer to your local distributor for guidance on national
insulation directives.

Insulation of Ducts in Heated Spaces
Genvex recommends, as follows:
Supply Air and Extract Air Ducts
If the loft is warm, insulate the supply air and extract air
ducts with 50 mm of insulation followed by aluminium foil.
Supply air and extract air ducts passing through heated
spaces in dwellings do not require insulation unless cooling,
a bypass or an earth heat exchanger is used. In this case,
the supply air duct must be insulated.
Fresh Air and Discharge Air Ducts
Insulate the fresh air and discharge air ducts in warm lofts
and heated rooms in dwellings with a minimum of 50 mm
insulation. Also cover the insulation externally with plastic
film or aluminium foil to avoid formation of condensate in
the insulation. Refer to your local distributor for guidance
on national insulation directives.
We recommend 100 mm of insulation on the fresh air duct
when an earth heat exchangeror precooling/brine coil is
used.
Water Connection
The following connections are located at the bottom of the
hotwater cylinder:
• 3/4” RG branch pipe for: Cold water/Recirculation/Hot water
Optional Connection of Heating Coil
The tank is fitted with a 0,75-mheating coil with 3/4" RG
connections.
The heatexchanger is enamelled externally.
The tank connections are 3/4” RG. A sensor controlling
external heat sources such as solar heating panels, an oil
burner or a wood burning boiler can also be mounted in the
free sensor pocket at the bottom of the tank. The maximum
diameter of the sensor is 6 mm.
Circulation
Solar collector output Solar collector input
Hot water Cold water

12
Electric Water Heater/Sensor/Anode/
Thermostat
These are placed on the bottom front of the unit, behind the
front cover and underneath a steel plate.
The electric backup immersion heater will ensure that
additional heating capacity can be applied if required.
This could be beneficial for example if the full capacity
of the Combi unit is dedicated to room heating or cooling.
The activation of the electrical backup heater in this case
will ensure that domestic hotwater can be produced
simultaneously.
The safety thermostat will trip at 80 °C and ensure that the
electrical water heater will not activate until the safety
thermostat has been reset. Resetting the thermostat is
done by pressing the small button on the thermostat.
The anode protects the domestic hotwater cylinder against
corrosion and should be checked every 2 years to ensure
that sufficient protection is present.
To check if the anode protection is intact, remove the
ground connection of the domestic hotwater cylinder and
use a multimeter to check if the anode current is greater
than 0,3 mA by measuring directly on the anode and the
ground connector.
Between the anode and electrical immersion heater, a
sensor pocket for the temperature sensor switching the
electrical heater on and off is located. Do not remove the
temperature sensor in the sensor pocket as this will
prevent the Combi controller from shutting down the
electrical heater if the temperature in the cylinder is
sufficient.

The unit may only be operated with a full tank.
The unit must always be disconnected from the
electrical power source before the front hatch is dis-
mantled. Once the unit has been disconnected from
the mains, wait until the fan has come to a standstill
before opening the hatch.
Do not drill any holes in the unit.
Electrical Installation
The connection to the mains must be performed by a
certified electrician. (See the enclosed electrical diagram).
On the top of the unit it is possible to connect an internet
connection for the connectivity features of the Combi.
Furthermore a Optima Touch display can be connected.
If the pre-installed 1.8 metre cable for the Optima Touch
display is not long enough, it is possible to replace this with
a 4-core 0.25 mm2twisted pair cable with a length of up to
50 metres.
System Inspection and Fine-Tuning
To ensure optimal operation of the system, fine-tune it first
using professional air-measuring equipment.
Check the following points, while keeping in mind that the
system can be put into operation before the fine-tuning.
1. Check that the system has been mounted correctly and
that all ducting has been insulated in accordance with the
instructions.
2. Check that the various hatches can be opened so that it
is possible to service and maintain the unit.
3. Check that the filters are clean (they can be dirty after
installation), and replace if necessary before fine-tuning.
4. Check that the condensation drainage is mounted cor-
rectly with a water trap and that this is protected against
frost.
5. Pour 1 l of water into each of the condensate trays and
check that the condensate flows away efficiently into
the drain. Ensure that both of the watertraps contain
100 mm watercolumn.
Default setting if the system is started up prior to
fine-tuning:
• Adjust all supply air valves so that the valve which is
closest to the unit is open at 3 turns from the closed
position, while the one furthest away is open at 8 turns
from the closed position.
• Then open the valves in between at 4 to 7 turns depending
on how close they are to the unit.
Filters can be replaced by removing the two top screws from the filterlid.
the filterlid can then be opened to access the filters inside the Combi unit.

14
Optimal Fine-Tuning of the System
Use air-measuring equipment. Check that all 5 items in the
section above have been carried out before performing the
fine-tuning. Then put the system into operation.
Set up the system for basic ventilation, i.e. speed 2. To
reduce energy consumption as much as possible, first
adjust the overall atmospheric volume to the desired level
by changing the speed settings in the Service Menu.
Then fine-tune the supply air and extract air valves with the
air-measuring equipment. Remember to lock the valves
when performing the fine-tuning and to turn the conducting
plate on the supply air valves so that air blows in the right
direction.
Finally, recheck and fine-tune the overall atmospheric vol-
ume by adjusting the speeds for Step 2 in the Service Menu.
Then adjust Step 1 and Step 3 to an appropriate interval in
relation to Step 2.
Please be aware that the airflow required during heatpump
operation can differ from when only ventilation is required.
Requirements to the Hot Water Circuit
The following materials can be used for the hot water in-
stallation:
• Copper
• Stainless steel
• Brass
• Synthetic materials
This naturally depends on the materials that have already
been used in the water circuit (of the dwelling). Incorrect
material combinations may result in corrosion damage.
This requires particular attention when
galvanised components and
components containing aluminium are used.
Initial Operation of the Water Circuit
• Fill the tank via the connector spigot and then air it out by
leaving one of the uppermost hot water spigots open until
no more air comes out.
• Recheck the entire water circuit for leaks.
• Connect the unit to the mains.
Inspect all connections of the water circuit for leaks after
start-up.
Cooling Circuit
The unit is delivered as a preassembled unit. No work needs
to be done on the cooling circuit. The control unit will
automati- cally assume control of all functions and start up
the compressor, fan, etc. in order to maintain the set water
temperature.

Heat Exchanger Operation
Heating Boiler
Heat exchanger operation is used if you, for example, only
want to heat water via an external heating boiler in the
winter (an oil burner, for example). Set the Combi unit to
the lowest acceptable water temperature, and it will then
function as an emergency back-up. Afterwards, it will be
the thermostat of the oil burner that will determine the
heating of the water.
This mode of operation requires the installation of an extra
sensor in the tank for controlling the boiler. The maximum
water temperature must be limited to 65 °C. The tempera-
ture can be exceeded for short periods of time, for exam-
ple, in connection with disinfection.
If the boiler is to function as an extra heat source for the
unit, the temperature of the thermostat of the boiler
should be set about 5 °C lower than the thermostat of the
unit itself. This will ensure that the boiler is only operating
when water consumption cannot be covered by the unit.
When the unit is put into operation, it is necessary to
ensure that sensor values are set as desired.
Wood burner or solar collector
This optional operational connection can be used if the
function of the unit is to be supported by a wood burner or
a solar collector installation.
Sensor T9 (see the diagram on the next page) measures the
temperature in the wood burner or the solar collector. If the
temperature is higher than the water temperature in the
tank, it is possible for the control unit to activate a circula-
tion pump which will circulate water through the coil in the
tank, thereby heating the water. Hysteresis can be set up at
0-5 °C. Maximum temperature is 60 °C. Above this tempe-
rature, the control unit will disengage the pump in order to
protect the tank.
Energy-Saving Tips
Do not set the water temperature higher than necessary.
The lower the temperature, the higher the efficiency of the
unit. Only use high temperatures when necessary
Fan Operation Tips
Do not ventilate more than necessary. Over-ventilation
often results in very low humidity inside the dwelling, which
causes discomfort. In addition, it is a waste of energy to
over-ventilate. However, always make sure that there is
compliance with the required minimum atmospheric
volume.
Rechecking
After installation, we recommend that you check that
all connections are water and airtight and that condensed
water will flow off without a hindrance.
