General

Operating range

The heat pump is designed exclusively for the heating of

heating circuit water and sanitary hot water. Considering

the application limits (see technical details), the heat pump

can be installed on new or existing heating installations.

The heat pump must be installed only outside.

The integration in ventilation systems or the use

of the cooled down air for refrigeration purposes

is not admissible.

Functioning of the air / water heat pump

The heat pump converts the low temperature heat of the

ambient air to a higher temperature. The fan on the heat

pump pulls in the air through the air-duct and conducts

it to the evaporator. The evaporator contains the liquid

agent which boils and vaporizes at low temperatures and

low pressure. The vaporizing heat is transferred from the

air which is cooled. The air is discharged to outside. The

compressor sucks in the vaporized agent and compresses

it to achieve a higher pressure. The compressed gaseous

agent enters the condenser, where it condenses at high

pressure and high temperature. The condensation heat

is transferred to the heating circuit water with resultant

increase in temperature.

The energy transmitted to the heating circuit water

corresponds to the energy transmitted from the ambient

air plus the small amount of electric energy for the

compressor.

Energy-saving use of the heat pump heating

installation

By choosing a heat pump heating installation, you have

acknowledged the need for environmental protection

by lower emissions and less consumption of energy. To

ensure your new heating system works as efﬁciently as

possible, please note the following:

The heat pump heating installation must be

correctly sized and installed.

Avoid unnecessarily high ﬂow temperatures.

The lower the ﬂow temperature at the heating

circuit water side is, the more efﬁciently the heat

pump works.

The controller must be set correctly!.

Preferably open the window totally to renew the

air. Compared to constantly pivot-hung windows

opening outward, this kind of ventilation reduces

the energy consumption and saves money!.

Scope of supply

Scope of supply heat pump basic device

• Compact device with fully hermetic compressor and

all relevant safety components for refrigeration circuit

monitoring, without a soft starter and without control-

ler.

•1 m tube for condensate drain, connected to the heat

Accessories necessary for operation

(Only original accessories made by manufacturer)

The heat pump is a functioning unit only combined with the

heat pump controller and the control- and sensor-line.

The heat pump controller controls and monitors the heat

pump and serves as heating controller at same time. The

control- and sensor-line is the connection between the

heat pump and the controller.

Our accessory range offers control- and sensor-lines of

different length, suitable for the installation conditions of

your heat pump.

TRANSPORT

830116GB/150915 - Subject to Technical Modiﬁcations - 5

Installation

When installing the device, please observe the

installation advice and the minimum distances in

the annex

The heat pump must be installed on a sustainable and ho-

rizontal underground. The base frame of the heat pump

must seat solidly.

As fundament material, use materials meeting these con-

ditions (concrete, sidewalk plates etc.)

The air temperature in the air outlet area may be

5K lower than the ambient temperature. Due to

this, under certain climatic conditions, there will

probably be an ice layer.

Therefore, the air outlet of the device should not

open out in the sidewalk area.

The surface in the air outlet area of the heat pump must

leak water.

The operating side of the heat pump must always be ac-

cessible for the service technician. When installing the heat

pump, please keep the following minimum distances:

Heating water supply point

The supply points are situated behind the right-hand

covering, seen from the operating side. Take of the co-

vering.

Connection to the heating system

The heating system must be ﬂushed before connecting

the heat pump to prevent contamination inside the heating

system affecting the function of the heat pump.

On the heat pump side, ﬂow and return must be equipped

with isolating valves to allow eventual ﬂushing of the con-

denser.

To avoid structure-borne sound transmissions to the hea-

ting system, the connection of the heat pump on the he-

ating circuit water side must be made by ﬂexible connec-

tions.

The ﬂexible connections must be insulated by the

customer in accordance with the valid prescriptions

/ standards.

(Hose clamps and ﬂexible connections available in our ac-

cessory range - “installation set”)

The outside heating water pipes must be insulated in ac-

cordance with the valid prescriptions / standards. They

must be laid underneath the frost line.

When connecting the heating circuit water pi-

pework, the connection point on the heat pump

must be secured against torsion with a spanner

in order to avoid damage to the copper pipe on

the condenser side.

Condenser ventilation

After ﬁlling the heating circuit with water, the condenser must be

ventilated by the ventilating valve.

Hydraulic schematic

The heat pump must be integrated to the heating circuit in

accordance with the recommended schematic, see schematic.

The heating circuit must be equipped with a safety valve and

an expansion tank in accordance with the current legislation for

pressure protection. Furthermore, ﬁlling and drain devices, gate

valves and return valves must be installed.

Pressure differential valve

The installation of the pressure differential valve is required to

ensure the minimum water ﬂow rate through the heat pump.

The pressure differential valve must be sized correctly to ensure

minimum water ﬂow rate through the heat pump even if the

heating circuit valves are closed.

Buffer storage:

A series buffer tank is needed to ensure a minimum running

time of the heat pump even if the heating valves are closed.

Size of the buffer storage:

The minimum heating circuit water ﬂow rate depends on the hea-

ting output of the heat pump; for further details see the technical

data sheet of the heat pumps.

With single source air/water installations, the buffer tank should

be installed on the ﬂow before the pressure differential valve.

Circulating pump

The heating circuit water and sanitary water circulating pumps

must be graded.

The use of variable speed pumps is not permitted!

Sanitary hot water heating

Sanitary water heating with the heating pumps takes place with a

second heating circuit run in parallel to the heating circuit. Please

note: during the installation, the return must not be connected to

the buffer storage.

Sanitary hot water storage

For sanitary hot water requirements using a heat pump, it is vi-

tal to have a large enough heat exchanger within the hot water

tank to ensure sufﬁcient volume and temperature of hot water

(<= 55°C).

The storage size must be big enough to ensure sufﬁcient sani-

tary hot water even during off-times by your local energy supply

company.

Alpha-InnoTec hot water tanks have special smooth bore pipe

exchanger surfaces. They are manufactured to match the re-

quirements of the heat pumps.

Condensate drain

The condensate tube must be laid in the device

vertically through the opening of the basic frame.

The frost-free condensate drain must be ensured. See

socket plan in the annex.
