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 guarantee you technically per-

fect equipment.

Please read through this documentation carefully.

It contains important information for correct

installation and safe and economical operation of

the system.

1.1. Standards and directives

Note for the installation of the heatpump follow all

effective national and international piping- and ins-

tallation rules and the instructions of this Installation

instruction.

Amongst others comparing the following:

- the general effective 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 company

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 spe-

cialist staff and commissioned by a customer service

company trained to do so by iDM-Energiesysteme

GmbH.

When working on the heat pump, the system must be

shut-off and secured against re-activation.

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 internal unit of the iPump A 3-11 should be ins-

talled in a frost-proof room. The Room temperature

should be between 5°C and 25°C.

To minimize vibrations and noises, the heat pump

must be isolate from the building structure. Basically,

the setting up of the heat pump on lightweight design

ceilings must be avoided. In case of a ﬂ oating ﬂ oor

screed the screed and the sound damping around the

heat pump have to be omitted.

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 evacuated

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, the room must be de- signed as

an machine room according to EN 378!

general information

1.5. Sound emission

The iPump A 3-11 outdoor unit is very quiet in opera-

tion thanks to the design. It is however important that

the site of the heater is situated as far as possible

from noise-sensitive living areas. This also applies to

refrigerant connection lines between the outside- and

the indoor unit.

Also the boiler room where the indoor unit of the

iPump A 3-11 is installed should be placed outside of

the noise sensitive living area. The boiler room should

be furnished with a good lockable door.

1.6. Ice-covering outdoor unit

Depending on the weather and outdoor humidity, it

may happen that there will be formed an icy covering

on the protective grids of the heat pump. This effect

is common occuring in nature. This covering must

be removed by the heat pump operator during this

weather periods.

1.7. Installing additional components

The installation of additional components which have

not been tested with the equipment may impair its

function. No liability is accepted and your guarantee

is void in the event of damage caused for this reason.

1.8. 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 required.

1.9. Cleaning

If necessary, the internal and the outdoor unit of the

iPump A 3-11 can be cleaned with a damp cloth. The

use of cleaning agents is not recommended.

1.10. Servicing and maintenance

Regular maintenance control and servicing of all

system components guarantee its safe and econo-

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

recommend a maintenance contract with the relevant

customer service company.

Only original spare parts which meet the requirements

of iDM may be used!

1.11. Service

For technical information please contact your relevant

iDM customer service department.

1.12. Warranty and guarantee

Warranty and guarantee conditions are included

in the purchased documents. For questions please

contact your relevant customer service department.

1.13. 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

acoustic evaluation

2. Acoustic evaluation

Sound power level

The sound power is the sound energy per second

emitted of a noise source. The sound power level is

speciﬁ c to the source of sound, independent of dis-

tance and direction and enables an easy comparison

of different sound emitting devices. The sound power

can only be determined via mathematical calculation

according to international standards of the series

ISO 3740 - based on sound pressure level measure-

ments - as well as ISO 9614, which is based on the

measurement of sound intensity. The sound power

level of the heat pumps can be found in the technical

speciﬁ cations.

Sound pressure level

In contrast to the sound power level, the sound pres-

sure level, which is caused by a noise source can be

measured. The measured sound pressure is depen-

dent on the distance from the noise source and the

receiver location (geometrical divergence) as well as

the local conditions. As the sound pressure level is a

measure of the loudness of noise sensed by humans,

the legislation deﬁ nes limit values, that must not be

exceeded.

Sound-propagation-outdoor

With increasing distance from a point noise source,

the sound power is distributed on an increasing area

due to spherical spreading. Therefore, the sound

pressure level is continuously decreasing with in-

creasing distance from the noise source to receiver

location. Doubling the distance leads to a reduction of

the sound pressure level of 6 dB(A). Besides the di-

stance from the installation site of the heat pump the

sound, the installation situation and local conditions

also have signiﬁ cant impact on the resulting sound

pressure level at the relevant place of immission.

Major factors of inﬂ uence are:

• sound attenuation by massive barriers e.g. buildings,

walls or different terrain.

• reﬂ ection on acoustically hard ground e.g. glass

facade and stone surfaces

• attenuation due to sound absorbing porous surfaces

e.g. grass, trees

• reinforcement/reduction of by wind speed/direction

Noise immission

The noise caused by an source at a certain place is

expressed as Immission, the corresponding sound

pressure level is called Immission level.The immissi-

on level at the relevant place of immission can either

be calculated with the iDM-sound calculator.

The calculation of the sound pressure level shall be

calculated by means of the following examples for

typical installation situations of the outdoor unit.

(C) IDM ENERGIESYSTEME GMBH Installation instructions iPump A 3-11 7

acoustic evaluation

Relevant place of immission

The sound immission have to be determined 0.5 m

in the middle in front of the open window (outside the

building) of the most affected rooms, which need par-

ticular protection. According DIN 4109:1989 rooms

needing particular protection are:

- Living- and bed rooms

- Children rooms

- Work spaces / ofﬁ ces

- Classrooms / seminar rooms

Rating level Lr .

The rating level corresponds to an equivalent conti-

nuous sound pressure level associated with a speciﬁ c

period. The rating level is determined for both rating

periods „day“ (6 am-10 pm) and „night“ (10 pm-6 am)

separately. The operation time of the heat pump has

particular impact on the resulting equivalent conti-

nuous sound pressure level. Reducing the operation

time from 16 h per day to 4 h per day the rating level

is reduced by 6 dB(A).

But the equivalent continuous sound pressure level

alone is not sufﬁ cient in order to determine the distur-

bing effect of noise. In general noise is perceived very

disruptive, if individual tones are clearly discernable

or the noise is irregular (impulsiveness). These noise

characteristics will be taken into account by applying

a surcharge. Additionally, daytimes with increased

sensitivity are taken into consideration. According the

„TA Lärm“ the following corrections are applied:

Information incorporation 3 or 6 dB(A)

Impulsiveness 0,3 or 6 dB(A)

Daytimes with increased

sensitivity 6 dB(A)

The rating level Lr shall be obtained by summing the

calculated immission level and the applied correc-

tions of the speciﬁ c periods.

Finally, the determined rating level can be compared

with legal limit values (e.g. „TA Lärm“).

Standard Immission Values (SIV) - relevant place of

immission outside the building:

Territory SIV-day SIV-night

Industrial area 70 dB(A) 70 dB(A)

Business park,

commercial areas 65 dB(A) 50 dB(A)

Village areas and mixed

areas 60 dB(A 45 dB(A)

Settlement area 55 dB(A) 40 dB(A)

Residential area 50 dB(A) 35 dB(A)

Spa area, hospitals 45 dB(A) 35 dB(A)

In case of sound propagation inside buildings or

structure-borne sound transmission the Standard

Immission Values for the rating level of rooms nee-

ding particular protection are as following:

SIV-day: 35 dB(A)

SIV-night: 25 dB(A)

For the calculation of the rating level according „TA

Lärm“ a calculation tool is provided at the hom page:

http://www.idm-energie.com

Tips for installation of heat pumps

• Sound reﬂ ections areas should be kept as low as

possible

• The installation on acoustically hard ground and

areas with depression in the terrain should be

avoided

• The distance from the heat pump and the relevant

place of immission should be as big as possible

• In case of outdoor installation the blow out of air

in direction to the neighbour or relevant receiver

location should be avoided

• The airﬂ ow should not be blown directly against

walls as sound reﬂ ections lead to increased sound

pressure levels accordingly

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

buffer) following 3 points have to be met.

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

heatpump at A35/W18. Minimum cooling consumption 2.4 kW

All 3 points must be fulﬁ lled independently. This is possible via the Navigator Pro. The entire distribution

system has to fulﬁ ll the 3 mentioned points. To ensure a large cooling demand, the cooling limit has to be set

as high as possible.

3.12. Limits of use

The heating of other ﬂ uids as heating water is not permitted with the iPump A 3-11 (for heating water quality,

see page 45). Heat pumps are by nature subjects to limits of use regarding of pressure and temperature (see

diagram). It is not permissible to operate the iPump A 3-11 outside these limits.

Note:

The following safety devices are included to protect the heat pump against faults:

- High pressure presostat

- Maximum ﬂ ow temperature limitation with automatic reset via the Navigator control

- Starting current limiter via inverter technology and performance adjustment

transport

Elektrischer Anschluss

In order to avoid damages during transport, the heat

pump should be transported to its place of ﬁ nal instal-

lation 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 lift down the heat pump 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 Indoor unit 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.

Transport of the outdoor unit

The outdoor unit should be transported as far as

possible to its place of ﬁ nal installation site. It is re-

commended to remove the protective wooden crate

only on site. The device must be lifted and secured

with a corresponding number of people.
