Devices for external installation must be placed on a level concrete foundation (chapter 4.2.5). For exact
position and dimensions of pipe connections, see technical data (chapter 7). Along with pipes for the
hydraulic connection, install also pipes with wire rope (it is advisable to separate the power / sensors).
Use this wire rope to lay the two external device’s power cables and the jacketed communication cable
from the utility room. The recommended diameter of this pipe is given in the table below and depends
on the dimension of the power cable.

4.2 Location of the device
CAUTION
The concrete pedestal must carry the weight of the device. See technical
information.
The device must be levelled
NOTE
It is obligatory to consider the minimal clearance from obstacles for ensuring unobstructed
access for maintenance and service of the device.
NOTE
The location of the device has to be accessible with manual transport devices to ensure
undisturbed delivery of replacement parts and equipment for maintenance and servicing.
Costs connected with hiring special equipment for installing the device, servicing and
maintenance are charged the operator separately and are not subject of the warranty.
The device must not be set up at a location, which is subject to stronger and lengthy gusts of wind (i.e.
bora wind); they could obstruct the normal air circulation through the evaporator which could result in
disruptions in operation.
In case the device is installed in the wind direction, it is necessary to install adequate wind protection.
Wind protection must be robust enough to prevent the influence of the wind. The best option is
a concrete or brick version.
The height and width of the wind protection must be at least 150 % of the basic dimensions of
the device. Only these dimensions enable adequate wind protection of the device.
The wind protection must be located at least 3000 mm away from the external device to ensure
sufficient air flow.
NOTE
The device must be set up in a leeward location.
NOTE
Salt or dust gathering on the outer heat conductor must be regularly cleaned (dust once
yearly and salt in coastal regions at least three times yearly) or rinsed with water.

4.2.1 Set up and connection of the external sensor.
For controlling the heating according to the external temperature, it is necessary to install the external
temperature sensor.
CAUTION
The sensor must be set up in a shady spot.
The sensor must not be set up above a window or door. It must be located
away from heat sources.
For measuring external temperature, the sensor type PT 1000 is used.

4.2.5 Concrete pedestal
The installation (connections above or below ground) routed from the utility room to the device does not
influence the make of the concrete pedestal.
Because of greater safety, installation using an underground cable duct is recommended (installation
V1).
Installation of the concrete pedestal
The reinforced concrete pedestal must be installed on a suitable buffered base. The recommended
minimal edge thickness of the pedestal is 60 mm. Width 1050 mm, depth 420 mm and height 600 mm.
CAUTION
The device must be screwed on the designated places (1) to the concrete pedestal because
of the possibility of stronger gusts of wind.

4.2.6 Wall penetration for the refrigerant and electro-communication connection
When installing a refrigerant and electro-communication connection between the internal and external
device, please note:
The passage through the wall must be drilled with a crown drill with the diameter of 70 mm for
laying pipe connections.
The hole for the pipe connection must be slightly sloped in the direction towards the external
device to prevent water penetrating into the building. See the diagram below.

4.3 Refrigerant pipe connection of the exterior and interior device
Connect the exterior and interior device with refrigerant pipes.
NOTE
Use insulated pipes for the installation of the connection between external and internal
device.
CAUTION
The refrigerant pipes filled with nitrogen are always laid closely sealed to prevent impurities,
air, moisture and contaminants penetrating the interior.
4.3.1 Determining the length of the connection pipes
When determining the length of connection pipes, follow the instructions for the maximal
allowed pipe length and the height difference between the devices.
CAUTION
The refrigerant pipes must not be installed alongside the heating in the screed or alongside
any kind of source of heat or cold.

The average length of the refrigerant connection between the devices is 7.5 m. The external device is
factory filled for connections of up to 15 m. For longer connections, it is necessary to supplement
the refrigerant according to the table below.

Example 1: When installing the external device and accompanying internal device with the distance of
30 m, it is necessary to supplement the system with additional refrigerant. The quantity of the refrigerant
is calculate with the following equation:
(30 m – 15 m) x 30 g/m = 450 g
In the given example, it is necessary to supplement the system with 450 gof refrigerant R410 A.
WPLV-14-S1 NT
Example 2: When installing the external device and accompanying internal device with the distance of
30 m, it is necessary to supplement the system with additional refrigerant. The quantity of the refrigerant
is calculate with the following equation:
(30 m – 15 m) x 60 g/m = 900 g
In the given example, it is necessary to supplement the system with 900 g of refrigerant R410 A.
NOTE
In case of installing an internal device which is higher than the external device and when
the height difference is 4 m or more, a qualified person has to manufacture oil siphons for
every 4 m of height difference to enable adequate oil transport.
In case the external device is higher than the internal device, oil filters are not necessary.
WARNING
The device contains the refrigerant HFC which is classified as a greenhouse gas according
to the Kyoto protocol. This is why operating the device is only allowed to persons authorised
for working with the refrigerant as defined by the national legislation in force. While
performing works on the device it is necessary to prevent the refrigerant to leak into the
atmosphere.
