4 TRANSPORT AND STORAGE
The appliance is delivered in one carton box.
The appliance should be stored and transported in such a way that it is protected against physical damage that can harm spigots,
casing, display etc.
It should be covered so that dust, rain and snow cannot enter and damage the unit and its components.
5 INSTALLATION
This section describes how to install the unit correctly.
The unit must be installed according to these instructions.
5.1 Unpacking
Verifythattheunit(andeventualaccessories)deliveredisaccordingtoorderbeforestartingtheinstallation.Anydiscrepancies
from the ordered equipment must be reported to the supplier.
5.2 Where/how to install
•All QR units are meant for indoor installation in a heated space.
•The unit must always be mounted horizontally.
•Mounttheunitonflatsurface(ceiling).
•It’s important that the unit is completely leveled before it is put into operation.
•Placetheunitpreferablyinaseparateroom(e.g.storage,laundryroomorsimilar).
•When choosing the location it should be kept in mind that the unit requires maintenance regularly and that the inspection door
should be easily accessible.
•Leavefreespaceforopeningtheremovablepanelandforremovalofthemaincomponents(see3.4).
•The outdoor air intake of the building should if possible be put in the northern or eastern side of the building and away from
other exhaust outlets like kitchen fan exhausts or laundry room outlets.
•The unit casing is provided with 2 drainage holes, two by side, to be used for condensation drainage either in case of ceiling
installation. Make sure that the not-used holes are tightly closed with the supplied plugs to provide water and air tightness.
