The height of the foundation slab or base frame
must allow for assembly of the P-trap which
drains the condensate out of the draining tray.
In case of the drain plates installed in the lower
AHU sections,
the unit has to be mounted onto an additional
foundation slab or a special hollow must be
made directly under the P-trap. The minimum
height of P-trap is given in the Draining out
condensate” section.
The horizontal air handling units can be
installed suspended.
Suspension of units requires external rigging
which shall be field-mounted.
Ensure the ceiling opening is large enough for
unit installation and maintenance
requirements.
The units delivered in sections should be
connected by the qualified personnel according
to the separate instruction AVS 8-380 section
connection manual.
During connecting the section one should
pay attention on the applying caulk on the
casing seams (connecting the sections
without using caulk will result in a lack of
casing tightness).
4.2.1 Service Access
The AHU shall be installed so that the connections of any related systems (ventilation ducts, pipelines,
cabling, etc.) do not collide with the inspection panels.
In order to carry out the operation and maintenance successfully, please keep minimum recommended
clearance (Fig.8) between the front side and existing construction elements (walls, pillars, pipelines, etc.)
This is possible to install other systems, pipelines, pillars in the operation area only if they will not hinder
the maintenance and service procedures.
The coils are connected on the front side of the unit.
CAUTION! It is forbidden to place any elements on the AHU as well as use the AHU as a
support of ventilation ducts and any other building components.

4.2.2 Rigging and Handling
Before preparing the unit for lifting, estimate the approximate center of gravity for lifting safety. Because
of placement of internal components, the unit weight may be unevenly distributed, with more weight in
the coil area. Approximate unit weights are given in the technical data of AHU and device’s nameplate’.
Before hoisting the unit into position, use a proper rigging method such as straps, slings, or spreader
bars for protection and safety. Always test-lift the unit to determine the exact unit balance and stability
before hoisting it to the installation location. In the case of vertical lifting, all the lifting lugs on the
section/unit must be used.
