3 System overview

3.1 Heat pump system design

5 - 11 kW

15 - 19 kW

The heat pump system consists of the following components,
as a minimum:

– Air/brine collector(s)
– Heat pump
– System controller

The heat pump system generates heat in heating installa­tions and in hot water generation by extracting the thermal
energy from a heat source circuit and releasing this into
the heating circuit via the internal refrigeration circuit. At the
same time, there is an opportunity for active cooling to take
place via circulation reversal. For this, the heat pump is con­nected to the air/brine collector(s). The air/brine collector is
used to exchange heat between the brine circuit and the out­side air.

5.3 Selecting the installation site

Caution.
Risk of material damage caused by corro-

sion.

Caustic vapours may cause corrosion dam­age on the product. The extracted air must be
free from ammonia, methane gas and other
corrosive elements.

▶ Do not install the product close to stables

and manure pits.

▶ Set up the product outdoors away from rooms. Depend-

ing on the weather, condensate may form and appear
under the collector.

– Maximum installation height: 2000 m above normal

sea level

▶ Ensure that there is a sufficiently stable, frost-proof, hori-

zontal foundation that meets local requirements and com­plies with the rules of structural engineering.

▶ For efficiency reasons, the clearance between the heat

pump and the air/brine collector should be kept as small
as possible.

– Total length of the connection line, cold brine and hot

brine: 2 x 30 m

▶ If the clearance between the product and the building

falls below 3 m, position the product in such a way that
the outlet side does not point towards the building.

▶ Assess the installation site to ensure that no persons can

be at risk at the outlet side. No public roads/pathways
should run through the area of the outlet side.

▶ Install the product with the intake side towards the wall

(recommended installation).

▶ Comply with the local and statutory minimum clearances

with regards to:

– Vegetation
– Walls
– Awnings
– Open fire or embers
– Children's toys

▶ When selecting the installation site, take into consider-

ation the fact that, during full load mode in winter, noise
(depending on the current output requirement, up to ap­prox. 66 dB(A) sound power level) is emitted from the
product, and this noise may be amplified by reverberative
surfaces.

▶ Observe the national regulations regarding noise.

LWA= 54 dB(A) – 10 lg (628)

LWA= 54 dB(A) – 28

LWA= 26 dB(A)

▶ Choose the installation site so that the legally required

emissions values for noise outside of buildings can be
complied with, without having to use the heat pump sys­tem's noise reduction function, if possible.

▶ In certain weather conditions, take into consideration

the possibility of black ice forming directly in front of the
product's outlet side; if condensate escapes, the black
ice may form all around the product.

5.7 Hydraulics installation

5.7.1 Routing the connection lines

Caution.
Risk of material damage caused by

ground lifting up as a result of frozen
ground.

At operating temperatures close to freezing
level, the ground in the area of the PE pipes
may freeze and therefore damage the struc­ture as a result of the ground lifting up.

▶ Insulate all of the PE lines that are to be

routed under buildings, terraces, path­ways, etc. so that they are vapour-diffu­sion-tight.

▶ If possible, route PE pipes in the ground

with a clearance of 70 cm from each other
and from adjacent supply lines (except for
electrical lines).

The total length (connection lines from the heat pump to the
product and from the product to the heat pump) must be no
greater than 60 m.

▶ Keep the clearance between the product and the heat

pump as short as possible and minimise the use of el­bows and angles. This is because each additional pres­sure loss that is caused by the use of these reduces effi­ciency.

▶ Route the PE pipes in accordance with the applicable

technical directives.

▶ For a total line length of between ≥ 20 m and 60 m, use

a PE pipe with DN 50 (e.g. PE 80/100, outer diameter
50 mm, wall thickness 4.6 mm). Up to a total line length
of ≤ 20 m, you can also use a PE pipe with DN 40
(e.g. PE 80/100, outer diameter 40 mm, wall thickness

3.7 mm).

▶ When using more than eight PE elbows, use an extra

2 m of pipeline for each elbow.

▶ When using copper pipes, use only copper pipes that

have a cross-section of ≥ 35 mm. If you use a smaller
cross-section (e.g. copper 28 mm), this will result in pres­sure losses (2 m copper 28 = 8 m copper 35).

Note

If the prescribed line cross-sections are not
complied with, this results in efficiency losses
and reduced annual operating figures.

▶ If required, when routing the PE pipes above-ground,

ensure that they are protected against UV radiation.

▶ Connect the air/brine collector in accordance with the

Tichelmann principle. This means that the air/brine col­lector with the shorter flow has the longest return.

Caution.
Risk of material damage caused by a leak.

When tightening screwed connections,
ensure that O-rings are inserted correctly
as, otherwise, they may pop out or become
jammed, become damaged, or cause leaks.

▶ Insert the O-rings properly and untwisted

into the cap nuts for the air/brine collect­or's brine connections.

▶ Screw the cap nuts to the connection adaptors on the

"hot brine" and "cold brine" brine lines in the brine circuit
(cross-reference) on the mounting base.

▶ To purge each individual air/brine collector, install

two shut-off units.

5.7.2 Transporting the product

Caution.
Risk of material damage caused by incor-

rect transport.

▶ Do not transport the product using a hand

truck.

▶ If required, remove the louvred grill to prevent damage.

5.7.3 Installing the product

1. Place the product on the base that is available as an
accessory.

2. Connect the brine lines to the product as shown.

* One way

1. Install the brine lines between the product and the heat
pump within the building and using all of the associated
components in accordance with the applicable technical
directives.

Note

Do not install dirt filters in the brine circuit for
a prolonged period of time. The brine fluid is
cleaned during the filling process.

2. Reduce the pre-charge pressure of the brine diaphragm
expansion tank (which is available as an accessory)
from 0.25 MPa (2.5 bar) to 0.10 MPa (1.0 bar).

3. Insulate all of the brine lines and the connections for
the heat pump and product so that they are vapour­diffusion-tight.

Note

Vaillant recommends that you install the
Vaillant heat pump brine filling unit. By do­ing this, it is then possible to carry out a pre­paratory partial bleed of the brine circuit, e. g.
the flow and return of the brine circuit to the
product.

5.8 Filling and purging the brine circuit

5.8.1 Calculating the required volume of brine

fluid

▶ Use the information in the following table to calculate the

required volume of brine fluid.

▶ Plan an allowance of 10 l for the calculated volume in

order to facilitate the rinsing process.

▶ Label the vessel for the remaining volume with informa-

tion about the type and concentration of brine fluid and,
after start-up, pass the vessel on to the operator so that
they have brine fluid available for when the tank needs to
be topped up.

5.8.4 Purge the brine circuit

1. Position a second person at the air/brine collector(s).

Note

The entire purging/filling process should last
at least 30 minutes. During this time, the pur­ging valves for the air/brine collector(s) must
be opened and closed every five minutes.
We recommend the brine purging support set
for the air/brine collector as this makes the
purging process significantly easier if it is to
be carried out by one person.

2. Remove the protective caps, which are attached and
transparent in their as-delivered condition, from the
purging valves on the air/brine collector and dispose
of these. These are no longer required.

3. Open the purging valves (69) on the air/brine
collector(s).

4. Start up the filling pump (67) in order to fill and rinse the
brine circuit.

5. Allow the filling pump (67) to run.

6. Close the purging valves on the air/brine collector(s)
as soon as brine fluid escapes from the purging valves
(69).

7. If required, open all of the other stop valves that are not
shown in the illustrations.

8. Open and close the purging valves (69) on the air/brine
collector(s) every five minutes consistently until air is no
longer escaping.

9. Open the stop valve (63) so that air in the pipeline
between the stop valves (61) and (62) can escape.

10. Close the stop valve (61).

11. Build up pressure in the system, as described in the

installation instructions for the heat pump.

5.9 Electrical installation

Danger!
Risk of death from electric shock caused

by a residual-current circuit breaker.

In certain cases, residual-current circuit
breakers may not work.

▶ If, to ensure that people are protected

properly and fire is prevented, residual­current circuit breakers are required, use
type A pulse-current-sensitive residual­current circuit breakers or type B univer­sal-current-sensitive residual-current cir­cuit breakers.

▶ Observe the technical connection conditions for connect-

ing to the power supply network operator's low-voltage
network.

▶ Use the values for the maximum rated power that are

specified in the technical data to determine the required
line cross-sections.

▶ In each case, take into consideration the on-site installa-

tion conditions.

▶ Connect the product using a fixed connection and a parti-

tion with a contact opening of at least 3 mm (e.g. fuses or
power switches).

▶ For the electricity supply, connect the product to a three-

phase 400 V AC network with a neutral line and an earth
line.

▶ Fuse this connection using the exact values that are spe-

cified in the technical data.

▶ At lengths of 10 m or more, supply lines must be laid sep-

arately from sensor or bus lines. Minimum clearance for
the extra-low voltage and mains voltage line at a line
length of > 10 m: 25 cm. If this is not possible, use shiel­ded lines. Lay the shielding on one side of the sheet for
the product's electronics box.

▶ Connect each air/brine collector to a three-phase 400 V

AC network with a neutral line and an earth line.

▶ Strip the voltage supply line by approximately 80 mm.

Shorten all of the conductors, except for PE, to 60 mm.
Remove the insulation by a maximum of 8 mm. If these
lengths are exceeded, there is a risk of a short circuit.

▶ If the energy supply company requires that the heat

pump is controlled using a blocking signal, also connect
the air/brine collector to the heat pump via the electricity
meter so that a block by the energy supply company can
be switched off for both products at the same time.

▶ Connect the eBUS connection X3 to the eBUS connec-

tion on the heat pump. Use a ground connection that is
suitable for laying cables underground and that has a
cross-section of at least 2 x 1.5 mm².

Conditions: Installing two air/brine collectors

▶ Place a junction box close to the heat pump and connect

the eBUS lines to this.

▶ Set the eBUS address switch for the first air/brine col-

lector to 1 and the eBUS address switch for the second
air/brine collector to 2.

5.9.4 Circuit breaker for the air/brine collector

A circuit breaker is used to secure the air/brine collector
against short circuits. If the circuit breaker has been
triggered, the air/brine collector remains switched off until the
short circuit has been rectified and the circuit breaker in the
connection box has been manually reset.

The fault message F.708 or F.782 is shown in the heat pump
display.

5.9.5 Resetting the circuit breaker for the

air/brine collector

1. Check the supply line to the mains connection PCB in
the air/brine collector's electronics box.

2. Check that the air/brine collector's mains connection
PCB is working correctly.

3. Check the supply lines for the air/brine collector.

4. Check that the de-icer is working correctly.

5. Rectify the short circuit.

6. Reset the circuit breaker in the connection box.

6 Start-up

6.1 Start-up

1. Ensure that the heat pump and system controller are
installed correctly.

2. Switch the fuses on so that the heat pump and air/brine
collector(s) are supplied with power.

◁ As soon as the heat pump is supplied with power

during the initial start-up, the software initialisation
starts in the heat pump and in the system controller.

3. Implement the other settings with the help of the install­ation instructions for the heat pump and for the system
controller.

6.2 Handing the product over to the operator

▶ When you have finished the installation, affix the en-

closed sticker (which requests that the user reads the
instructions) to the front of the product in the operator's
language.

▶ Explain to the operator how the safety devices work and

where they are located.

▶ Inform the operator how to handle the product.
▶ In particular, draw attention to the safety information

which the operator must follow.

▶ Inform the operator of the necessity to have the product

maintained according to the specified intervals.

▶ Pass all of the instructions and documentation for the

product to the operator for safe-keeping.

7 Inspection and maintenance

7.1 Inspection and maintenance interval

Annual inspection/maintenance of the product by a compet­ent person is a prerequisite for ensuring that the system is
constantly ready for operation, reliable and has a long ser­vice life.

The inspection is intended to determine the actual condition
of the product and compare it with the target condition. This
is done by measuring, checking and observing.

Maintenance is required in order to eliminate any deviations
between the actual condition and the target condition. This is
normally done by cleaning, setting and, if necessary, repla­cing individual components that are subject to wear.

Danger!
Risk of death from electric shock!

The air/brine collector has its own, separate
power supply and is not automatically de-en­ergised when the heat pump is disconnected
from the power source.

▶ Always switch off the power supply for

each air/brine collector before carrying out
any inspection or maintenance work.

▶ Secure the power supply against being

switched on again.

Danger!
Risk of death from electric shock!

Due to electrical discharge processes, con­tact with components inside the product may
cause an electric shock.

▶ Do not open the cover for the electronics

box in the product until three minutes after
the all-pole disconnection of the supply
voltage.

▶ Do not remove the louvred grill until at

least three minutes after the all-pole dis­connection of the power supply. Never
try to take hold of the ventilator before the
three minutes have elapsed.

Decommissioning 8

0020217119_01 aroCOLLECT Installation and maintenance instructions 21

7.2 Carrying out inspection and maintenance
work

Note

Due to the fluctuating outside temperature and
air humidity, it is normal for frost to form or for
the heat exchanger to freeze in the product. In
normal mode, the product automatically starts up
a thawing procedure.

▶ Check the product for dirt and, if required, clean it.
▶ Check the condensate discharge for blockages and, if

required, remove any dirt/blockages.

▶ Check the air inlet and outlet to ensure that the supply

and exhaust air is unobstructed and, if required, request
that the operator removes any vegetation or similar (min­imum clearances). (→ Page 9)

▶ Request that, in winter, the operator regularly ensures

that the product is free of snow on the intake and outlet
side.

Application limits for the heat pump: Heating and cooling (heat source = air)

At the same volume flow rates in the heating circuit (ΔT 5K or ΔT 8 K) as for the nominal heat output test under standard
nominal conditions.

Operation of the pump outside the application limits results in the heat pump being switched off by the internal control and
safety devices.
