Product delivery
Upon delivery, inspect the product for
damage caused during transport and
ensure the delivery is complete.
Record any damage or missing parts on
the transport documents.
Complaints regarding obvious transport
damage or incomplete deliveries cannot
be considered if made too late.
On the construction site, protect the unit
against dirt, impact and the elements.
4.1. Unloading / transport to
location of installation
This unit is shipped in parts on a pallet.
For unloading, lift the unit by the pallet.
Too short forks can damage the acoustic
housing.
Risk of serious injury or damage to
property from dropping loads.
Observe the safety instructions of the
transport equipment and lifting gear.
Do not climb onto the unit.
4.2 Information on the storage of products made from Magnelis
Please note the following: If stored improperly, products made of Magnelis can be
damaged by corrosion, also known as "white rust". In order to minimize the risk of white
rust, suitable precautions must be taken during transport and storage. All products made
of Magnelis should preferably be stored inside, or with a suitable cover outside, in a clean
and dry place away from any chemical contamination. To avoid white rust, Magnelis
should, as far as possible, be stored at constant temperatures above the dew point. Rapid
changes in temperature lead to condensation and subsequently to white rust. In addition,
the products made of Magnelis must always be stored on pallets made of wood or metal in
order to avoid direct contact with the floor.
It is recommended not to store products made of Magnelis outdoors. If this is unavoidable,
however, it is important to observe the following precautionary measures: Set up a
scaffolding around the stored material and cover it with a waterproof film, tarpaulin or
similar cover. Leave enough space between the cover and the packages or coils to allow
air to circulate. Store the parcels at a slight incline so that rainwater can drain away
without touching the ground. Check the storage area at regular intervals to avoid getting
wet on the material. Note that all products (stored above, in the middle or below) can also
get wet due to nighttime condensation and this water cannot evaporate. Keep the period
of storage outdoors as short as possible, especially during the summer months, the rusting
process is greatly accelerated by the higher temperatures.

Manual HTAcoustic Housing 7
Installation of unit
At the place of installation, it must be possible to provide impeccable service and
maintenance and the necessary air intake of the built-in air-conditioning, refrigeration
and heat pump units.
When planning the installation site, the guide lines for minimum distances
around the air-conditioning, refrigeration and heat pump manufacturer must be
respected.
The acoustic louvre, on the suction and exhaust sides has a depth of 200mm and the
site must enable this to remove to have access to the built-in air conditioning,
refrigeration and heat pump equipment.
Important NOTE:
Please always use the required safety work gear during installation. Due to the
packaging materials and the production process, personal injury may occur, such as
hand injuries.
If the soundproof housing is freely accessible, the necessary measures during
assembly should be taken to local conditions to avoid personal injury.
Magnelis
“The warranty applies to all buildings exposed to normal atmospheric corrosion factors, in
other words excluding those subject to permanent spraying with fresh water or salt
water; in the case of buildings situated in coastal areas, excluding those exposed to sea
spray.”

Manual HTAcoustic Housing 8
Usage limitations of Magnelis
Like most other metallic-coated steel sheet, Magnelis is not recommended:
•When in contact with copper, lead, moist concrete and in alkalineenvironments.
•In cattle sheds (ammoniac vapours)
For fixings, only use accessories made from:
•Magnelis
•Aluminium
•Stainless steels
•Synthetic material
(nylon)
Important NOTE:
1. Due to the production process there can appear a minor possibility that oxidation of
certain cutting edges become visible. This oxidation is locally and does not affect the rest
of the acoustic cabin. This can be prevented by optionally ordering the acoustic cabin
powder painted in a specific RAL colour. Alternatively, the oxidation can be post treated
with applying manually Alu-Zinc paint (which is common available) from aesthetic point of
view.
2. The tightening torque of the screw must be 5 to 15 Nm, so that the screw does not cut
into the housing and damages the Magnelis coating.

5.3 Connection for refrigerant pipes and power supply
There is a possibility to enter with refrigerant pipes and power supply in the
sound insulation housing, both on the left and on the right side, in case the entry is
not foreseen through the bottom.

Manual HTAcoustic Housing 15
5.4 Foundation
The foundation must meet the relevant static and sound propagation requirements
and must feature a proper drain for water. It must be level and smooth. The
resonance frequency of the support structure must be distinctly different from the
excitation frequency of the rotating machine components (Heat Pump, Air
Conditioning and Refrigeration system).
An uneven foundation might cause malfunction or jammed panels. Liability is
excluded for damage caused by installation on an uneven surface.

Manual HTAcoustic Housing 16
Note 1:
In case of a complete foundation (=AxB), a frost-proof drain of the condensate must
be provided locally.
Note 2:
Just as with an installation without a soundproof enclosure and if there are no other
local regulations that a drain collection should be used as environmental protection, it
is possible to drain the condensation water from the heat pump, for example, into a
gravel bed, which was carried out professionally for an appropriate water drainage. In
addition, a protection against plant growth from below is to ensure.
5.5 Installation of Heat
Pump, Air Conditioning
and Refrigeration
outdoor unit
The correct installation position of the
air conditioning, refrigeration or heat
pump unit is decisive for the fit and
function of the acoustic housing.
Maintenance and Service
6.1 General
