General information

By purchasing this system you have acquired a

modern and efﬁ cient heating system. Ongoing qua-

lity controls and improvements as well as functional

checks at the factory guarantees you a technically

perfect equipment.

Please read through this documentation carefully.

It contains important information for correct in-

stallation and safe and economical operation of

the system.

1.1. Standards and directives

For the installation of the heatpump follow all relevant

national and international piping- and installation re-

gulations and the instructions given of this Installation

instruction.

Amongs others comparing the following:

- the general rules for accident prevention and safety

regulations

- the regulations for environmental protection

- the provisions/regulations of the professional asso-

ciations.

- the effective laws, standards, guidelines and regu-

lations e.g. DIN, EN, DVGW, VDI and VDE

- regulations of the local suppliers/supply companies

1.2. Safety instructions

Installation and maintenance work can be hazardous

due to high system pressure, high temperatures and

live parts and may only be carried out by specialist

staff. Heat pumps may only be installed by competent

specialist staff and commissioned by a customer

service company trained to do so by iDM Energiesys-

teme GmbH.

When working on the heat pump, the system must

be shut-off and secured against unintentional restart.

In addition, all safety instructions in the relevant do-

cumentation, stickers on the heat pump itself and all

other applicable safety regulations must be observed.

1. General information

1.3. Storage

Heat pump components may not be stored outdoors.

Heat pumps should not be stored in wet rooms or in

potentially dust rooms.

1.4. Installation room

The TERRA SWM should be installed in a frost-proof

room. The Room temperature should be between

5°C and 25°C!

To minimize vibrations and noise, the heat pump must

be isolated from the building structure. Basically,

setting up of the heat pump on light weight design

ceilings must be avoided. In case of a ﬂ oating screed,

the screed and the sound damping have to be omitted

around the heat pump.

The installation in wet rooms or in potentially dust or

explosion-endangered rooms is not allowed.

Gas from refrigerants in plant rooms must not escape

into vicinal rooms, stair rooms, courtyards, walks or

into the drainage system of the building. The gas has

to be channelled off safely!

In case of danger, the plant room has to be evacua-

ted immediately.

In case a natural ventilation is not possible, a me-

chanical ventilation has to be provided. A mechanical

ventilation has to be equipped with an independent

emergency control outside of the machine room near

the door.

Heat pumps should not be installed in rooms with high

electromagentic inﬂ uences from other installations!

If the minimum size of the installation room falls below

the required value as described in the technical data,

the room must be designed as an machine room accor-

ding to EN 378!

(C) IDM ENERGIESYSTEME GMBH Installation instructions TERRA SWM 5

General information

1.5. Sound emission

The TERRA SWM is very quiet in operation thanks to

the design. It is however important that the boiler room

is situated as far as possible from noise-sensitive

living areas. A well-closing door should be installed.

1.6. Installing additional components

The installation of additional components which have

not been tested with the equipment may impair func-

tion. No warranty or liability is assumed for damages

resulting from this.

1.7. Construction drying and screed heating

The heat pump is not designed for the increased heat

requirements when drying out construction work or

heating plaster or screed. This must be covered by

equipment to be provided by the customer, if requi-

red.

1.8. Cleaning

If necessary, the TERRA SWM can be cleaned with

a damp cloth. The use of cleaning agents is not re-

commended.

1.9. Servicing and maintenance

Regular maintenance, control and servicing of all

system components guarantees safe and economi-

cal operation in the long term. To achieve this, we

recommend a maintenance cotract with the relevant

customer service company. Only original spare parts

which meet the requirements of iDM may be used!

1.10. Service

For technical information please contact your relevant

iDM customer service department.

1.11. Warranty and guarantee

Warranty and guarantee conditions are included

in the purchased documents. For questions please

contact your relevant customer service department.

1.12. Disposal

Heatpumps are electrical equipment made from

high valuable materials, which are not allowed to be

disposed like normal household garbage, but have to

be disposed professional and proper according the

regulations of the local authorities.

A non-proper disposal can cause, apart from sanc-

tions for the violator, environmental damages and

harm for your health.

This device is characterized according to the euro-

pean directive 2012/19/EU on waste electrical and

electronic equipment (Waste electrical and electronic

equipment - WEEE). The guideline provides the

framework for an EU-wide return and recycling of old

equipment.

Dispose the device properly and do not damage the

pipes of the refrigerant circuit.

On the refrigerant side the TERRA SWM is

„hermetically tight“.

2. Description

2.1. Description

The iPump is a brine-water heat pump with a Scroll-

compressor with Inverter-technology.

The microprocessor controller NAVIGATOR 2.0 en-

sures efﬁ cient operation of the heat pump. The heat

pump system is controlled as needed and is equipped

with a variety of monitoring-, security- and reporting

functions.

By default, one heating circuit can be regulated. Sys-

tems up to six heating circuits can be realized with

optional heating circuit extension modules.

A colored 7“ touch display simpliﬁ es the operation of

the heat pump.

The connections of the brine lines are inside the heat

pump. The connections for heating lines are also

inside. All connections can be feed out either on the

right or left side of the heat pump.

The LAN-connection, the cable inlet for the sensors

and the power supply are on the backside. The USB-

port is integrated in the front part and is closed by a

stopple when delivered.

TERRA SWM is available with HGL or with HGL and

process reversal (P). Thereby the heat pump can be

used for cooling.

The TERRA SWM heat pump is working with the sa-

fety refrigerant R410A. It circulates in an closed circuit

when installed and commissioned properly, meaning

that there is no environmental impact.

The lower the maximum ﬂ ow temperature

is set, the higher is the efﬁ ciency of the

heat pump.

2.2. Application range

The TERRA SWM can be used for monovalent hea-

ting and cooling of single and multiple dwellings with

ground heat utilisation.

In this case the building should be equipped with low-

temperature heating (e.g. underﬂ oor heating, wall

heating, low temperature radiator heating).

The heat pump may only be used for domestic and

not for purely commercial operation!

Description

2.9. Performance data - cooling according to EN 14511

In order to guarantee a correct cooling mode, when working with unregulated direct-heating circles (without

cooling buffer), the following 3 requirements have to be fulﬁ lled:

1. To ensure the minimum volume of heating site, appropriate zones have to remain open all the time.

Minimum volume 80 lt.

2. To ensure the minimum ﬂ ow rate of heating site, appropriate zones have to remain open all the time.

Minimum ﬂ ow rate 1.01 m³/h

3. To ensure the minimum cooling output rate of distribution system, appropriate zones have to remain open

all the time. The minimum cooling output rate is 70 % of the minimum cooling output power of the heat-

pump at S30°C/W18°C. Minimum cooling power consumption 2.8 kW

All 3 requirements must be fulﬁ lled independently. This is possible applying the NAVIGATOR Pro. The entire

distribution system has to fulﬁ ll the 3 mentioned requirements.

To ensure a large cooling demand, the cooling limit has to be set as high as possible.

Description

2.10. Limits of use

The TERRA SWM must only be used with the heat

media of brine or groundwater. No other heat media

are permissible. In addition, the heating of other ﬂ uids

as heating water is not permitted (for heating water

quality, see page 29).

Heat pumps are by nature subject to limits of use

based on pressure and temperature (see diagram).

It is not permissible to operate the TERRA SWM out-

side these limits of use.

Note:

The following safety devices are included to protect

the heat pump against faults:

- electronic high- and low pressure monitoring

- Flow-maximum temperature limiter with automati-

cally reset via the NAVIGATOR 2.0 control

Transport

In order to avoid damages during transport, the heat

pump should be transported to its ﬁ nal installation

site in packed condition on the wooden palett with a

forklift or hand lift truck.

The components and the tubing of the heating- and

heat source site must never be used to transport the

heat pump.

When heat pump is lifted from the wooden palett,

there is a risk of tilting. Therefore, the device must be

lifted and secured with a sufﬁ cient number of persons.

The weight of the heat pump must be considered!

Transport of the heat pump via stairways

The heat pump can be lifted down the stairways step

by step with a sack barrow. A sufﬁ cient number of

persons for securing the device during the transport

shall be present.

If the heat pump must be transported without the

wooden pallet and the protective wooden crate,

it is important that there will be no damage on the

housing.

3. Transport
