1. BASIC INFORMATION
1.1. Who is the instruction for?
The manual is addressed solely to the ventilation installers.
1.2. Installer qualifications required for the installation of an AirPack4h MVHR unit
Installation works may only be carried out by installers with knowledge of applicable law, standards and good engineering practice
in the field of:
1. occupational health and safety,
2. safety of low voltage installations,
3. building ventilation systems,
4. sewage systems,
5. environmental protection.
2. DEVICE INSTALLATION
This section of the manual will guide you through the following stages of AirPack4h recuperator assembly:
•mechanical assembly of the device
•installation of control panels,
•extension of functionality based on the standard built-in BASIC controller,
•extension of functionality based on the additional Expansion module.
For ease of use, we have provided a flow chart before each stage.
2.1. Mechanical assembly of the device.
This part of the guide will lead you step by step through the mechanical assembly of the AirPack4h.

STEP 1 —Checking the technical conditions necessary for the operation of AirPack4h
1. The electrical installation supplying the AirPack4h has a
residual current protection. Protection is necessary for
the safety of users and the correct operation of fan motor
inverters.
2. The cables supplying the socket to which the AirPack4h
device will be connected have a cross-section of 2.5 mm2
(or larger). Appropriate cross-section of wires will ensure
correct operation of the electrical system.
3. The air temperature in the range from -15 ° C to + 50 ° C
will be provided in the room where AirPack4will be in-
stalled. Temperature <-15 ° C can lead to condensation of
moisture on the housing surfaces and freezing of conden-
sate in the tray. Temperature> 50 ° C can damage the
structure of materials.
4. The device will not be exposed to precipitation.
5. The device will not be exposed to direct sunlight. Radia-
tion can raise the material temperature above the limit
value (despite the correct ambient air temperature).
6. The space for mounting the AirPack4h device allows to
keep the minimum distances of the device housing from
building partitions and other obstacles as per the diagram
below.

STEP 2C —Wall mounting AirPack4h on WallGrip4console
1. Make sure that the load on the wall structure resulting
from the AirPack4installation does not threaten in any
way the safety of the building structure or people staying
in it.
2. Remove the two wall brackets from the packaging that
are the WallGrip4console and the 8 plastic screws for at-
taching the console to the AirPack4device.
3. Prepare the mounting holes in the wall, maintaining the
distances shown in the figure below. Each of the console
handles has 5 mounting holes. For proper installation, use
at least two holes on each console, furthest apart
4. Fasten the console to the wall with screws or bolts se-
lected depending on the type of wall so as to ensure the
safety of the device and people in the room.
5. Place AirPack4on the console attached to the wall as
shown below.
6. Fasten the AirPack4device to the console with 4 plastic
screws using a TORX T25 screwdriver and a screwdriver

IMS.AirPack4h. 02.2020.1 9
STEP 2D —Suspended mounting of AirPack4h on CeilingGrip4console
1. Make sure that the load on the wall structure resulting
from the AirPack4installation does not threaten in any
way the safety of the building structure or people staying
in it.
2. To perform the assembly, you need 4 M8 threaded rods,
which are not supplied with the CeilingGrip4system.
3. Remove the two CeilingGrip4system rails and 8 plastic
screws designed to attach the console to the AirPack4de-
vice.

the spacing of the ø9 mm mounting holes which are
placed at the ends of the CeilingGrip4rails (according to
the drawing below showing the positions of the Ceiling-
Grip4 rails in top view).
5. Fasten the CeilingGrip4rails on the threaded rods by
passing the rods through these holes. Use self-gripping
nuts and washers for fixing.
6. Level the CeilingGrip4rails using the nuts
7. AirPack4on the console attached to the wall as it is shown
below.
8. Fasten the AirPack4to the console with 4 plastic screws,
using a TORX T25 screwdriver and a screwdriver with a
set torque of 1.5 Nm.

muff end connector of the condensate drainage system
onto this drainpipe.
5. If the recuperator is located in a room where the winter
temperature drops below +1oC, secure the condensate
drain installation with a heating cable. Start by wrapping
the condensate drain connector around it. The ambient
temperature sensor should remain factory-fitted at the
connection port.
6. If the AirPack4 h ambient temperature does not fall below
+1oC in winter, and the condensate installation is passed
through a room where the temperature drops below +1oC,
secure the condensate installation with a heating cable
on the section at risk of freezing. Install the ambient tem-
perature sensor in a place where it measures the air tem-
perature at the point where you expect the lowest temper-
ature to occur in winter.
7. Connect the heating cable according to the following in-
structions: Remove the connection port covers (the cover
is mounted on neodymium magnets). Then remove the
protective cover securing accession to the heating cable
connector.
8. Connect the heating cable to socket no. 2 of the connec-
tion port.
9. Install an overlay to secure access to the heating cable
connector.
CAUTION!
RISK OF ELECTRIC SHOCK!
10. Under no circumstances leave the port with unscrewed
overlay as this may cause electric shock.
11. Mount the previously removed connection port cover (It
is mounted on neodymium magnets).
