Installation
The air-handling unit blocks are packed in PE foil.
Warning: When transporting, respectively handling
the air-handling unit blocks, it is necessary to pay inc-
reased attention to those parts (pipes, closure valves,
etc.) projecting from the walls of the air-handling unit
block. All blocks may only be transported in the same
position in which they are operated!
Rotary Heat Exchanger Handling
Increased attention must be paid to the safety of persons
as well as of the product when handling the rotary heat
exchanger block, which due to its dimensions (tall and
narrow), weight and high centre of gravity is very unstable.
The manufacturer recommends always fixing the rotary
heat exchanger in position by suitable roping if it is not as-
sembled in the block assembly! The rotary heat exchanger
can only be stored, transported or handled in the vertical
position. Any tilting may damage the rotor flatness.

do not tilt!
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
-20°C to+40°C.
The air-handling units must be protected against pene-
tration of dust and caustic vapours, or other chemical sub-
stances which could cause corrosion of the air-handling
unit's structural components and equipment.
The air-handling units must not be exposed to the
direct effects of solar radiation.
AeroMaster Cirrus air-handling unit blocks may only be
stored in the same position in which they are operated.
Prior to installation, the following must be
checked
Delivery completeness
Delivery integrity
Volubility of rotary components
(fans, dampers, rotary heat exchanger)
Parameters of the power supply and connected energy
media sources
Any found fault must be removed before starting the
installation.
Air Handling Units
Identification of Components
The association of blocks and built-in assemblies to the
particular purchase order number is indicated on the name
plate of each block and built-in assembly, i.e. device num-
ber. All blocks bearing the same device number create
an air-handling unit. The manner of the blocks' assembly
is apparent from the assembly drawing included in the
accompanying technical documentation (respectively our
offer) marked with the same order (device) number.
Air-Handling Unit Location
The surface of the site for the air-handling unit installation
must be level 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. Observan-
ce of this condition 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 gas heater block, it is necessary to
maintain safety distances from inflammable materials
in accordance with national directives and standards of
the state of installation (in the Czech Republic – ČSN 06
1008). No inflammable materials are allowed to be stored
within the area of the gas heater block installation
Warning: The base frame or base frame and founda-
tion height should respect the condensate drainage
siphon height if not resolved in another way (e.g. em-
bedding into the floor or installation on an additional
base frame of the required height).
Service Access
When planning the air-handling unit location, it is necessa-
ry to keep sufficient space for maintenance, service and
operating. The need for this space depends on the air-han-
dling unit configuration, i.e. on the operational blocks used.

Keep these distances from the wall to enable service and access:
0.8 x width (W) of the air-handling unit: fan
1.15 x width (W) of the air-handling unit: heater, cooler, drop
eliminator, filter, plate heat exchanger and rotary heat exchanger.
Every service access can be visualized in the AeroCAD program.
