Intended use
The hydraulic module is a functionally-necessary
accessory for dual air/water heat pumps intended for
outdoor installation. Taking into account the limits of
application, the unit can be used in combination with an
outdoor installation dual air/water heat pump in new or
existing heating systems.
The unit may be used only for the intended use. This
means, in conjunction with a dual air/water heat pump:
•for heating
•for cooling (RX variants only)
•for domestic water heating
The unit may be operated only within its technical
parameters.
Overview “Technical data / Scope of delivery”
and overview “Technical data / Scope of delivery”
of the operating manual for the heat pump to
which the hydraulic module is connected.
Disclaimer
The manufacturer is not liable for losses resulting from
any use of the unit which is not its intended use.
The manufacturer’s liability also expires:
•if work is carried out on the unit and its
components contrary to the instructions in this
operating manual.
• if work is improperly carried out on the unit and
its components.
•if work is carried out on the unit which is not
described in this operating manual, and this
work has not been explicitly approved by the
manufacturer in writing.
•if the unit or components in the unit have been
altered, modied or removed without the explicit
written consent of the manufacturer.
Safety
The unit is safe to operate for its intended use. The
construction and design of the unit conform to current
state of the art standards, all relevant DIN/VDE
regulations and all relevant safety regulations.
Every person who performs work on the unit must
have read and understood the operating manual prior
to starting any work. This also applies if the respective
person has already worked with such a unit or a similar
unit or has been trained by the manufacturer.
Every person who performs work on the unit must
comply with the applicable accident prevention and
safety regulations. This applies in particular to the
wearing of personal protective equipment.
DANGER!
Risk of fatal injury due to electric shock!
Electrical connections may be installed
only by qualied electricians.
Before opening the unit, disconnect the
system from the power supply and secure
it from being switched back on!
WARNING!
Only qualied technicians (trained
heating, cooling and electrical technicians)
may perform work on the unit and its
components.
WARNING!
Observe safety labels on and in the unit.
ATTENTION !
For safety reasons:
Never disconnect the unit from the power sup-
ply, unless the unit is being opened.

Customer service
For technical information please contact a qualied
technician or the manufacturer’s local partner.

Warranty / Guarantee
For warranty and guarantee conditions, please refer to
the purchase documents.
NOTE.
Please contact your dealer concerning warran-
ties and guarantees.
Disposal
When decommissioning the unit, always comply with
applicable laws, directives and standards for the recovery,
recycling and disposal of materials and components.
“Dismantling”.
Heat metering
In addition to proof of the unit’s efciency, the
EEWaermeG also requires heat metering (hereafter
referred to as HQR). Heat metering is mandatory for
air/water heat pumps. Heat metering for brine/water
and water/water heat pumps only have to be installed
for a ow temperature ≥ 35 °C. The heat metering must
record the total thermal energy released (heating and
domestic hot water) in the building. In heat pumps with
heat metering, the analysis is carried out by the regulator.
The regulator displays the thermal energy discharged in
the heating system in kWh.
Operation
Your decision to purchase a heat pump or a heat
pump system is a long-term contribution to protecting
the environment through low emissions and reduced
primary energy use.
You can operate and control the heat pump system
with the control element of the heating and heat pump
regulator.
NOTE.
Make sure that the control settings are correct.
Operating manual of the heating and heat pump
regulator.
To ensure that your heat pump or heat pump system
operates efciently and ecologically, the following are
especially important:
€ENERGY SAVING TIP
Avoid unnecessarily high ow temperatures.
A lower ow temperature on the hot water side
increases the efciency of the system.
€ENERGY SAVING TIP
Preferably use rapid ventilation. To save energy
and reduce your heating costs, do not leave win-
dows open for long periods.
Care of the unit
The outer surfaces of the unit can be cleaned with a
damp cloth and household cleaning products.
Do not use cleaning or care products that contain
abrasives, acids and/or chlorine. Such products would
destroy the surfaces and could also damage the technical
components of the unit.

Maintenance of the unit
The components of the heating circuit and the heat
source (valves, expansion vessels, circulating pumps,
lters, dirt traps) should be inspected and cleaned as
necessary - however, at least once a year - by qualied
personnel (heating or cooling system tters).
It is best to arrange a maintenance agreement with a
heating installation company. The company will arrange
the necessary regular maintenance work.
Malfunctions
In the event of a fault, you can read out the cause of the
fault from the diagnostic program of the heating and heat
pump regulator.
Operating manual for the heating and heat pump
regulator.
ATTENTION
Only customer service personnel authorised by
the manufacturer may carry out service and re-
pair work on the components of the unit.
Note that no malfunction is displayed if the safety
temperature limiter on the electric heating element has
tripped.

INSTALLATION
CAUTION!
Ensure the wall has the necessary load bearing
capacity.
Possible installation situation,
Example: HMD 1/E with row tank
1 Hydraulic module
2 Buffer storage tank
3 Domestic hot water tank
Hold the drilling template at the right height and
mark the 3 drilling holes…
Note the safety and service clearances required,
see “Installation plan”.
Lift the hydraulic module out of the box:

Subject to change without notice | 83053600eUK – Translation into English of the original German operating manual | ait-deutschland GmbH
Remove the top section from the front by pulling on
the recessed grips.
Example: HMD 1/E:
1 Recessed grips
Remove internal packaging material (transport
safeguards).
Use the anchors and bolts supplied to x the
hydraulic module to the wall:
CAUTION!
Hands and ngers could be crushed during
the following tasks!
The anchors are only suitable for use in the following
types of walls:
•Concrete
•Solid lightweight concrete blocks
•Cavity blocks made of lightweight concrete
•Cellular concrete
•Prestressed concrete - hollow ceiling/oor slabs
•Natural stone with sealed joints
•Solid sand-lime blocks
•Perforated sand-lime bricks
•Solid bricks
•Vertically-perforated bricks
•Hollow oors/ceilings made of clay bricks,
concrete or similar
•Solid gypsum boards
•Gypsum boards and gypsum bre boards
•Particle boards
The board material must be dimensioned with sufcient
thickness to ensure secure xing.
Appropriate xing material must be provided on site for
other types of wall constructions.
ATTENTION
Leaving a gap between the unit and the wall
helps back ventilation and may not be sealed
or closed off.
Cable ducts must be laid at a distance of at
least 2 cm from the hydraulic module.
FOR REVERSIBLE VARIANT:
Mount thread covers on the hanger bolts…
Screw adapter with safety component onto hydrau-
lic module.
Following the leak test, use insulation included in
the scope of supply to insulate adapter and safety
component.
