Report accidents, incidents
Accidents or incidents are reported to IV Produkt.
1.3 Product liability
The unit complies with industry requirements for quiet air handling units with high-efficiency
recovery systems for heating and cooling.
Declaration of conformity (CE marking)
The air handling unit and any associated cooling unit or reversible heat pump are CE marked
and meet the applicable requirements of the related directives under the declaration of
conformity. The declaration can be downloaded from IV Produkt’s order portal. See "2.1 IV
Produkt’s order portal, support”, page 9. The declaration applies only to the unit in the
configuration in which it was delivered and assembled according to this assembly instruction.
The declaration does not include components added later or modifications to the unit.

Order Portal
Nor does the declaration apply to other plant in which the unit forms a part. The product may
not be put into service until the plant in which it is included complies with the requirements for
CE marking.
Manufacturer
The air handling unit is manufactured by:
IV Produkt AB, Sjöuddevägen 7, SE-350 43 VÄXJÖ
Warranty
For proper function and for the warranty to be valid, the assembly instructions must be
followed.
Extended warranty
Extended warranty is a supplement to the order and to claim extended warranty (5 years),
according to ABM 07 with Appendix ABM-V 07 or according to NL 17 with Appendix VU 20, a
complete documented and signed IV Produkt Service and Warranty book must be presented.
Disclaimer
Continuous product development may give rise to specification changes without notice.
1.4 Receive, unpack
Check the goods on arrival, to ensure that no damage has occurred during transport.
When delivered, the product is packaged with plastic to protect against rain and dirt. The
packaging should be kept on as long as possible to avoid penetration of dirt and dust into the
unit. Duct connections on outdoor units are protected with a sheet metal covering.
1.5 Storage, transport
For temporary storage, the product should be placed on a flat surface, in a dry environment.
The original packaging should be unbroken. Condensation water, which can occur during
storage in fluctuating temperatures, normally dries up when the unit is installed and in opera-
tion. For extended periods of storage outdoors, the packaging should be opened to ensure
ventilation inside the parts. The parts of the unit should be protected from rain, snow and
sunlight.

Lifting should be carried out according to lifting instructions in this document, "4 LIFT THE
UNIT”, page 14 as well as according to markings and signs on the unit. If there are no lifting
instructions or markings, lifting must be carried out according to lifting methods prepared by
the transport industry.
1.7 After the lifetime of the product
For dismantling and decommissioning of air handling units, follow the instruction “Air handling
unit, dismantling and decommissioning” on IV Produkt’s order portal. See "2.1 IV Produkt’s
order portal, support”, page 9.

5 PREPARE ASSEMBLY
When setting up the unit, it shall be horizontal at the longitudinal leading
edge, as well as slightly inclined forward (towards the inspection side) to
create proper drainage of condensation water. See "6.1 Assemble adjus-
ter foot (accessory), adjust the height”, page 18.
Inlet grilles and duct systems shall be designed and installed so that:
• water is prevented from penetrating into the unit.
• recirculation and short-circuiting between the exhaust air and outdoor air is prevented.
• drainage cannot run backwards to the unit.
The duct system shall be designed and the control system configured to prevent pressure
increase through filter/air ducts, for example by soft-starting fans and opening dampers when
fans are operating. See "12 DUCT CONNECTION, DUCT ACCESSORIES”, page 39.
Water trap is mounted as indicated. See "11 CONNECT DRAINAGE, WATER TRAP”, page
37.
5.1 Sectioned configuration (Easy Access)
The counter-flow exchanger (TXM) can be delivered in pieces and must be assembled before
being put in place on the support. See "6 ASSEMBLY, GENERAL”, page 18 and ."14. Ensure
everything is properly iassembled.”, page 28
5.2 Create service area, electrical safe distance
• The service area in front of the unit should be about 1.5 x the depth of
the unit so as to allow for service, replacement of parts and cleaning.
• Follow the National Electrical Safety Board's recommendations regar-
ding the free service space to be located in front of electrical connecting
equipment.
