3.3 Specifications for cooling mode
!CAUTION - Observe the following points
when using the heat pump for room cooling.
Failure to comply poses a risk of damage due
to moisture in building elements (due to con-
densation).
–If the temperature falls below the dew point tem-
perature in the cooling system (lines, cooling sur-
face, buffer tank), water precipitates out of the air.
Condensation forms on the cooled system parts.
–The system must have insulation suitable for coo-
ling (=diffusion-resistant).
–Take particular care when using carbon steel -
risk of external corrosion
–Use room control with humidity sensor, e.g.
SOLARFOCUS Art. 26610. This regulates the
cooling flow temperature, taking the room tem-
perature and room humidity into account, and pre-
vents the temperature falling below the dew point.
–If room control with humidity sensor is not used:
Position the dew-point sensor on the lines.
–For further information, see Heat pump planning
document, DR-0302
–Standards
–ISO 12241 - Thermal insulation for building equipment
and industrial installations - Calculation rules
–DIN 4140 - Insulation work on industrial installations and
building equipment - Execution of thermal and cold insu-
lations
3.4 Installation location, installation posi-
tion
–Outdoor installation only
–The ground must be seepable (due to condensate
discharge > 6) and local regulations and con-
ditions must be observed.
–The heat pump is weatherproof and requires no
additional protective measures (roofing, ...).
Exception: In the event of a risk of roof avalan-
ches, mechanical protection for the heat pump
must be provided, e.g. protective roof).
–The air flow through the evaporator must not be
impaired on the air intake and exhaust side (e.g.
by shrubs, walls,...).
–Do not install the heat pump with the air outlet
side against the main wind direction. Preferred
installation is on a wall, with minimum distance,
see foundation plan > 38.
–Take noise development into consideration (do
not place in front of the bedroom window, next to
the terrace, near neighbours ...).
–Ensure free accessibility (e.g. for service work).
–Installation in a sink is not permitted (lack of air
exchange due to sinking, cold air).
–The sucked air must not be contain ammonia.
The use of exhaust air from animal stables is the-
refore not permitted.
–When using heat pumps near the sea, the high
salt content of the air can lead to increased cor-
rosion (invalidation of warranty if ignored). The
use of heat pumps is harmless from a distance of
12 km to the sea.

3.5 Foundation for the heat pump
Requirements for the foundation
The foundation for the heat pump must fulfil the fol-
lowing requirements:
–Horizontal orientation
–Weatherproof, frost-proof
–Sufficient load-bearing capacity
–Seals the heat pump at the bottom (prevents
sound output; prevents the ingress of rodents)
–Vibration-resistant
Concrete foundation
–In the case of a primary circuit connection from
below > 24 provide the required feed-throughs in
the concrete foundation.
–Position the heat pump directly on the concrete
foundation (affix the supplied sealing tape to the
underside of the heat pump base > 18)
–Screwing the heat pump to the concrete foun-
dation is not required
–Insulate the heat pump laterally with moisture-resi-
stant XPS panels (do not use EPS panels)
–Optional: For easy preparation of the concrete
foundation see article Insulating brick for foun-
dation (Art. No. 25350, Instructions DR-0132).
This XPS-shaped block allows fast, convenient
formation of the foundation, including the precise
placement of the heat pump pipe.
Condensate discharge
iWhen defrosting the evaporator, condensate
accumulation of up to 50 litres per 24 h is pos-
sible, even over a longer period. This quantity
of fluid must be reliably discharged.
2 methods of discharging:
Drain into the ground: If sufficient water-permeable
earth layers are present, it is sufficient to lay the drain
pipe in gravel fill to a depth of 90 cm (frost-free) > 38 ff
!CAUTION - When placing the heat pump
close to the building, it must be ensured that
the condensation does not damage the buil-
ding.
!CAUTION - Use a perforated version ("drai-
nage pipe") as on-site drain pipe > 22.
Discharge into the sewage system: Outdoors is pos-
sible, or to frost-free depth indoors (basement, ...) is
possible. In both cases provide sufficient slope and
trap (siphon) If a part of the drainage hose can not be
laid frost-free, it must be heated by a heating cable.
►Connect the condensate drain line > 22
Permissible installation types
–On continuous concrete foundation
–On concrete flat roof
Impermissible installation types
–On pad or strip foundation
–On structures that can oscillate (e.g. supporting
frames made of wood or metal, terraces, light-
weight ceilings)
–On wall/facade (e.g. with metal support bracket)
3.6 Line routing, connection
Protect lines against frost
–Lay the heat pump pipe (with heating flow and
return line) at frost-free depth.
–Lay the outlet of the condensate drain hose > 6 to
frost-free depth.
Observe heat pump pipe connection

3.7 Heating system fill-up water
In regard to the fill-up water quality, two key points
must be observed (in accordance with Guideline
VDI2035):
–Avoiding scale buildup (limescale)
–Avoiding water-side corrosion (caused by oxygen
in the heating water)
The lowest possible rate of corrosion of the installed
metal materials is primarily achieved when the circula-
tion water is in the correct pH range (8.2 to 9.5), while
at the same time, the electrical conductivity is as low
as possible (50 to 100 µS/cm).
3.7.1 Avoiding scale buildup
What is scale buildup?
Scale buildup is the formation of firmly adhering depo-
sits on water-contacting walls of hot water heating
systems. This can subsequently lead to damage
(stress cracks in metal, leaks).
Causes of scale buildup
The cause of scaling is the presence of calcium carbo-
nate in the water.
The following calculation/table determines the total
permitted hardness of the fill-up water. If the value is
exceeded, the fill-up water must be treated, e.g. sof-
tened.
Calculation of the total permitted hardness of the
fill-up water
To use the table, the specific system volume for the
system must be determined:
System volume divided by total heat output results in
the specific system volume
1166 litres / 25 kW =46.64 l/kW specific system
volume
Table:Total permitted hardness of the fill-up water
Total heat
output
Specific system volume (VDI 2035)
<20
l/kW
≥ 20 <50
l/kW
≥ 50
l/kW
< 50 kW ≤ 16.8°dH ≤ 11.2°dH < 0.11°dH
50 - 200 kW ≤ 11.2°dH ≤ 8.4°dH < 0.11°dH
20 - 600 kW ≤ 8.4°dH < 0.11°dH < 0.11°dH
> 600 kW < 0.11°dH < 0.11°dH < 0.11°dH
In our example: if the total hardness of the fill-up
water is more than 11.2dH, then the fill-up water
must be treated.
3.7.2 Avoiding water-side corrosion
Corrosion is usually triggered by the available oxygen
in the water. This value can be brought into a safe
range with proper planning, design, installation and
maintenance of the heating system. A constant input
of oxygen should be avoided.
Important in this regard:
–Expansion tank > 8: Air must be prevented from
being drawn in when the heating system is coo-
ling down. Ensure:
–Correct planning and implementation of the
expansion tank.
–Regular check of the system pressure, expan-
sion tank pre-pressure.
–Immediate repair of leaks in the heating system.
–In the case of older underfloor heating, ensure
pipes are diffusion resistant > 9
Check the pH of the fill-up water
–The pH value must be between 8.2 and 9.5.
–If this pH value does not self adjust after a week of
operation, it must be raised by adding 10 g/m³ tri-
sodium phosphate (Na3PO4) or 5 g/m³ sodium
hydroxide (NaOH). Allow 2 to 4 weeks of ope-
ration before further corrections.
–Exception: If aluminium materials are used in the
heating system, a pH from 8.2 to 8.5 must be met
(pH> 8.5 increased corrosion tendency).
Resistance of materials to water constituents
Irrespective of legal requirements, the following limit
values in the heating water used for different mate-
rials may not be exceeded or fallen below in order to
ensure safe operation of the heat pump. For this, an
analysis of the water must be carried out before com-
missioning.
If the pre-commissioning water analysis for one indi-
cator shows a "-" or an "o" for two indicators, treat-
ment of fill and make-up water is required.

The water quality should be rechecked after 4 to 6
weeks as it may change due to chemical reactions
during the first few weeks of operation.
Electrical conductivity
The probability of corrosion usually decreases with
decreasing electrical conductivity of the heating
water.
Low salt operation - filling with demineralised
water, see VDI 2035 sheet 2.
Low salt
Electrical conductivity at 25°C < 100 µS/cm
In the case of low-salt operation, feeding with non-
demineralised water can have a significant effect on
the pH value and push it into a critical range.
►Check the pH value regularly.
3.8 Information about the hydraulic
connection
Pressure equalisation through expansion tank
–The expansion tank prevents air from being
drawn in when the system cools down (issue: oxy-
gen input, heating system's fill-up water > 7)
–Dimension the expansion tank with a capacity of
12% of the total hydraulic system volume.
–Secure the expansion tank against shut-off. To do
this, either use the shut-off options on the way to
the expansion tank as cap valves, or unscrew the
hand lever (handwheel) and attach it to the expan-
sion tank with the wire in a clearly visible position.
–Installation of an expansion tank or a pressure
maintenance system is essential. Use of open
expansion tanks is not permitted.
–The pressure in the heating system (can be read
off the manometer) and the set pre-pressure in
the expansion tank must be checked regularly.
Install the temperature sensor in the immersion
sleeves
–Install the flow and return temperature sensor of
the heating system in the immersion sleeves.
–Exceptions are only permitted in the case of
installation in copper or carbon steel lines. In this
case, correct insulation of the sensor must be
ensured.
Installing the dirt and sludge separator
–Installation of a filter (<25μm) is a condition for
guarantee and warranty claims, e.g. use
SOLARFOCUS dirt and sludge separator. This
prevents the ingress of particles into the plate
heat exchanger (condenser).
Return hose version (structure borne sound
decoupling)
–To prevent structure-borne sound transmission
(and thereby resulting noise), a minimum length
of 30 cm and arched line routing must be obser-
ved for the primary circuit return hose; see infor-
mation on design > 23
8 Installation manual vampair

4 Product information
Caution with (older) diffusion-open plastic pipes,
e.g. existing underfloor heating
–In the case of older underfloor heating, the dif-
fusion-open plastic pipes can result in increased
oxygen input in the heating system. This has a cor-
rosion-inducing effect on the heating system com-
ponents (see: Avoiding water-side corrosion > 7).
–In this case, the system must be separated
(through installation of a heat exchanger).
–Newer plastic pipes (since around the mid 1980s)
are diffusion resistant in line with DIN 4726.

4.4 Principle of operation
The function of a heat pump is similar to that of a ref-
rigerator from a technical standpoint, but reversed.
The refrigerator extracts heat from the food to be coo-
led and releases it to the room air.
The heat pump vampair withdraws heat from the out-
side air and delivers it to the heating system.
Four processes are decisive in the cooling circuit of
the heat pump:
Evaporation
The evaporator (2) takes the circulating refrigerant
energy from air and changes its state from liquid to
gaseous.
Compression
In an electrically driven scroll compressor 3, the
gaseous refrigerant is heated by compression.
Liquefaction (condensation)
The absorbed thermal energy is delivered to the hea-
ting system. The gaseous refrigerant is cooled in the
condenser (plate heat exchanger) and liquefied again
4.
Expansion
The pressure of the liquid refrigerant is reduced, resul-
ting in partial evaporation. The result is a mixture of
liquid and gaseous refrigerant (= wet steam). The ref-
rigerant cools down.

4.5 Innovative technologies
Inverter technology
The scroll compressor not only works in on/off mode,
but is operated with output control (modulating, accor-
ding to the current power requirement).
Advantage:
–Precise power adjustment.
–Increased efficiency through reduced pulsing.
–Quieter operation on average due to reduced
speed in the partial load range.
–Reduction of the power of secondary drives (fan,
primary circuit pump)
Enhanced Vaporized Injection
In the scroll compressor, wet steam is injected from
the economizer heat exchanger for cooling.
Enhanced Vaporized Injection increases efficiency,
while the power requirement is reduced at the same
time. Thus higher flow temperatures and higher
heating output (especially at low outside tempe-
ratures) are possible. The compression temperature
decreases, increasing the life expectancy of the
compressor.
