Installation
Rotary Heat Exchanger Transport
Increased attention must be paid to the safety of persons as well
as of the product when handling the rotary heat exchanger, which
due to its dimensions and high centre of gravity is very unstable.
The manufacturer recommends fixing the position of the rotary
heat exchanger by suitable roping always if it is not assembled in
the section assembly! The rotary heat exchanger can only be stored,
transported or handled in the vertical position. Any tilting may
damage the rotor's evenness. If the section dimensions exceed the
height of the truck, it is necessary to cover it with an additional
tarpaulin.
All undivided rotary heat exchangers with a rotor diameter greater
than 1800 mm will be equipped with numbered tilt and impact
detectors registered by the manufacturer. The integrity of these
indicators is a condition for the guarantee to stay valid.

Storage Conditions
As standard, the air-handling units are packed in PE foil. They must be
stored in indoor rooms complying with the following conditions:
Maximum relative air humidity must not exceed 85 %.
No moisture condensation
Ambient temperature must be in the range from -20 °C to +40 °C.
The air-handling unit must be protected against penetration
of dust and caustic vapours, or other chemical substances
which could cause corrosion of the air-handling unit's structural
components.
The air-handling unit must not be exposed to the direct effects of
solar radiation.
Sections of air-handling units may be stored only in the position
identical to their working position.
Stacking
Only transport blocks of sections of the AeroMaster XP 04, 06, 10,
13 series are allowed to be stacked providing the following rules are
observed:*
1.
Only two sections may be stacked upon each other.
2.
The section placed on the upper row must be without the base
frame.
3.
The section placed on the upper row must not overlap in any
direction the one on the lower row.
4.
Protective elements must be inserted between stacked
sections to protect them against damage.
5.
The fan section must always be situated below.
6.
Plate and rotary heat exchangers cannot be stacked.

Installation Site
The surface of the site for the air-handling unit installation must be
levelled and flat. Maximum misalignment of the floor or supporting
structure intended for the air-handling unit installation must not
exceed 1 mm per 1 meter. This maximum misalignment must also be
retained if installing air-handling units equipped with base frames with
adjustable feet (for the adjustment procedure, refer to „AeroMaster
XP Air-Handling Adjustable and fixed Feet"). Observance of this condi-
tion is important for installation as well as for the air-handling unit
operation. The air-handling unit equipped with an integrated base
frame does not need any special anchoring. It is advisable to ground
the air-handling unit with grooved rubber stripes. When installing the
rotary heat exchanger, it is necessary to retain the frame's rectangu-
larity, which influences the volubility of the rotor and leak tightness
of the section. When installing the gas heater section, it is necessary
to retain safety distances from inflammable materials in accordance
with national directives and standards of the state of installation (in
CZ - ČSN 06 1008). No inflammable materials are allowed to be stored
within the area of the gas heater section installation.
Figure 7 – Service access
Keep these distances from the wall to enable service access:
0.8 x width (W) of the air-handling unit for the fan section.
1.15 x width (W) of the air-handling unit for the heater, cooler, filter, plate and
rotary heat exchanger sections.
Any service access can be visualized in AeroCAD software
Service Access
When planning the air-handling unit location, it is necessary to keep
in mind sufficient space for maintenance, service and operating. The
need for this space depends on the air-handling unit configuration, i.e.
on the operational sections used.
Pre-Installation Inspection
Prior to installation, the following must be checked:
Intactness of the delivery (completeness according to the bill of
delivery)
Volubility of rotary components (fans, dampers, rotary heat
exchanger)
Parameters of power supply and connected energy media sources
Any found fault must be removed before starting the installation.
