divided base frame. The 150 mm base frame is attached to the plate
heat exchanger section while the other parts („feet") of the base
frame, including connecting material, are attached separately to the
delivery. For „feet" installation, refer to „AeroMaster XP Air-Handling
Unit Adjustable and fixed Feet"..

Attention!
During installation, it is ESSENTIAL to retain alignment of the AeroMas-
ter XP unit and rectangularity of the heat exchanger. Failing to main-
tain the above-mentioned condition will result in rotor displacement,
which will influence the tightness and service life of the air-handling
assembly. It is advisable to connect one side of the heat exchanger to
the assembly first and then check the rotor alignment (the distance
between the wheel circumference and face walls must be aligned and
the rotor must not drag in any position when freely rotated).
If any problems occur, wheel centring must be performed (contact
the manufacturer's service department). After positioning the rotary
heat exchanger, push the sealing brushes in the dividing plane against
the rotor.
Rotary Heat Exchanger Positioning and Installation
The rotary heat exchangers for dimensional series XP 10 and above
are always equipped with a 150 mm base frame. If 300 mm or 400
mm base frames are used with the installed unit, it will be necessary
to install a separate foot on the base frame to eliminate the height
difference (see figure # 15).

Attention!
A rotary heat exchanger is one of the most expensive components
in the air-handling assembly; poor and/or incorrect installation can
result in costly repairs. Misalignment can be caused by improper
handling during transport and/or failing to observe conditions for
its correct installation. If the misalignment prevents free rotation of
the rotor, the rotor will have to be centred using a centre screw. If
this is the case, contact the manufacturer of the air-handling device.
To check the heat exchanger rotor fouling, it is necessary to perform
regular monitoring of the heat exchanger rotor pressure loss.
The heat exchanger rotor pressure loss must not exceed 15% of the
pressure loss value measured on a new rotary heat exchanger. To
enable regular service, maintenance, guarantee and post-guarantee
service, it is necessary to provide service access from both sides of the
heat exchanger's rotor. If this is not enabled by the air-handling unit
assembly arrangement, the air-handling assembly must be designed
so that the heat exchange can be pushed out from the air-handling
assembly.
Heating and Cooling Media Feeds
All media feeds are connected to the outer side of the air-handling
unit. The internal interconnection is made during production in the
factory. The corresponding connection points are marked with labels
(see figure # 17).
