General

Field of application

The heat pump is designed exclusively for the heating of

heating circuit water and domestic hot water. Considering

the application limits (see annex), the heat pump can be

installed on new or existing heating systems.

The heat pump is intended only for outside

installation. 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

outside air to a higher temperature. The fan of the heat

pump sucks in the air and conducts it to the evaporator of

the heat pump. The evaporator contains the liquid agent

which boils and vaporizes at low temperatures and low

pressure. The vaporizing heat is transferred from the

air with resultant decrease in temperature. The cooled

down air is blown 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 system

By choosing a heat pump heating system, 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 system must be

correctly sized and installed.

Avoid unnecessary high forerun temperatures.

The lower the forerun 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 controller

• 1 m tube for condensate drain, to be connected at the

Installation

When installing the device, please consider the

enclosed assembly instructions and the mini-

mum distances.

The heat pump must be installed on a sustainable and

horizontal 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 is 5K

lower than the ambient temperature. Due to this,

under certain climatic conditions, there will pro-

bably 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

accessible for the ﬁtter. When installing the heat pump,

please consider the following minimum distances:

Assembly / Heating water supply point

Connection to the heating system

The heating system must be ﬂushed before connecting

the heat pump to prevent contamination inside the hea-

ting 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 he-

ating system, the connection of the heat pump must be

made with ﬂexible tubes.

In accordance with the current legislation and stan-

dards for heating systems, the connecting tubes

must be insulated on-site.

(hose clamps and tube available as accessories as “in-

stallation set”)

The outside heating water pipes must be insulated in

accordance with the current legislation and standards for

heating systems. 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.

6 - We reserve the right to make technical changes - 830123GB/161130

Assembly / Heating water supply point

Inside the device, the condensate tube must not touch

the coolant pipes.

Make sure the condensate drain is frost-free - see

enclosed plan of pedestal.

Condenser ventilation

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

ventilated with the enclosed exhaust valve.

Assembly / Hydraulic schematic

The heat pump must be integrated in the heating circuit in

accordance with the recommended hydraulic schematic - see

enclosure.

In accordance with the valid regulations for pressure protection,

the heating circuit must be equipped with a safety valve and a

pressurized expansion vessel.

Furthermore, ﬁlling and draining devices, gate valves and no

return valves must be installed.

• Pressure differential valve

A pressure differential valve must be installed to secure the

heating water side minimum water ﬂow rate through the heat

pump. The overﬂow valve must be sized to allow the minimum

water ﬂow rate through the heat pump even though the heating

circuit is closed.

• Buffer tank

For the hydraulic integration, a series buffer tank must be

provided. This buffer tank secures a minimum running time

of the heat pump when the heating valves are closed. The

minimum heating-circuit water ﬂow rate depends on the heating

capacity of the heat pump - for further details please see the

technical data sheet of the heat pumps.

With single-source air/water systems, the buffer tank should be

installed on the ﬂow before the pressure differential valve (see

hydraulic schematic).

• Circulating pump

The heating circuit water and domestic water circulating pumps

must be graded.

The use of variable speed pumps is not permitted!

• Domestic water heating

Domestic water heating with the heating pump 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. From the control technology

point of view, the water heating takes priority, as long as it is not

stopped by the clock timer program.

• Domestic hot water storage

For domestic hot water requirements using a heat pump, it is

vital to have special domestic hot water storages. It is important

to have a sufﬁciently sized heat exchanger within the hot

water tank to ensure the heating capacity of the heat pump is

transferred with lowest possible spread with a heating circuit

water ﬂow temperature < 55°C. The storage volume must be big

enough to ensure the required domestic hot water quantity even

during off-times by your local energy supply company.

Our product range includes domestic hot water storages with

special plain ended pipe exchangers matching with our heat

pumps.
