1.1 DESCRIPTIONOFTHEPRODUCT.
Magis Combo4-6-9V2 is a hybrid heat pumpconsistingof:
- Magis Combo4-6-9V2 indoorunit;
- AudaxPro 4-6-9V2outdoorcondensingunit.
Magis Combo V2 is perfectly operational only if the two units are
correctlypoweredandinterconnected.
e Magis Combo V2 indoor unit was designed solely for wall
mounted installationforheatingandair conditioningandtopro-
ducedomestic hot waterfordomesticuseandsimilarpurposes.
In order to operate properly, it must be paired with an Audax Pro
V2 condensing unit; as such, all the provisions regarding the sa-
fe t y a nd u s e of b ot h ap p l i a n c e s mu s t b e re s p e c t e d .
1.2 INSTALLATIONWARNINGS
Operatorswhoinstallandservicetheap-
pliance must wear the personal protecti-
veequipmentrequiredby applicablelaw.
e place of installation of the appliance and relative
Im me r ga s ac c e ss or i e s mus t have su it a ble feat u re s (te ch-
nical and structural), such as to allow for (always in safe,
ecientandcomfortableconditions):
- installation (according to the provisions of technical
legislationandtechnical regulations);
- maintenance operations(including scheduled,perio-
dic,routineand specialmaintenance);
- removal(tooutdoorsin theplaceforloading andtran-
sporting the appliances and components) as well as
the eventual replacement of those with appliances
and/orequivalentcomponents.
By varying the type of installation the classication of
theindoorunitalso varies, precisely:
- Type B23 o B53 indoor unit if installed using the rele-
vant terminal for air intake directly from the room in
which theboilerhas beeninstalled.
- Type Cindoorunitifinstalled using concentric pipes
orothertypesofpipesenvisionedforthesealedcham-
berboilerforintakeofair andexpulsion ofuegas.
Only a professionally enabled company is authorised to
install Immergasappliances.
e wall surface must be smooth, without any protru-
sions or recesses enabling access to the rear part. ey
are not designed to be installed on plinths or oors
(Fig. 1).
Installation must be carried out according to regulation
standards, current legislation and in compliance with
local technical regulations and the required technical
procedures.
It is forbidden to install appliances removed from other
systems.
e manufacturer declines all liability in the event of
damage caused by appliances removed from other sy-
stems orforany non-conformitieswith such equipment.

e appliance operates with R32 refrige-
rantgas.
isgasisODOURLESS.
Paytheutmostattention
Strictlyfollowtheinstructionhandbook
oftheUE Audax Pro outdoor unitbefore
installationandanytypeofoperationon
thechillerline.
R32 refrigerant gas belongs to the low
ammability refrigerant category: class
A2L according to standard ISO 817. It
guarantees high performance with low
environmental impact. e new gas re-
duces the potential environmental im-
pact by one third compared to R410A,
having less eect on global warning
(GWP 675).
Check the environmental operating conditions of all
partsrelevantto installation,referring to thisbooklet.
Beforeinstallingthe appliance, ensure thatit is delivered
in perfect condition; if in doubt, contact the supplier
immediately.
Packingmaterials (staples, nails, plasticbags, polystyre-
nefoam,etc.)constituteahazardandmustbe keptoutof
thereach of children.
If the appliance is installed inside or between cabinets,
ensure sucient space for routine servicing; for mini-
muminstallationdistances,seeFig. 3.
If installing a kitorservicing theappliance,always emp-
tythesystem’s domestichotwater circuitrst soas notto
compromise the appliance’selectricalsafety(Parag. 2.8,
2.9).
Always disconnect the appliance from voltage and, de-
pending on the type of operation, decrease the pressure
and/orbringitto zero inthegasandDHW circuits.
Keep allammableobjects awayfromtheappliance (pa-
per,rags, plastic, polystyrene,etc.).
Do not put household appliances under the indoor unit
as theycouldbe damagedifthesafetyvalve tripsorifthe
hydraulic ttings leak. Otherwise, the manufacturer
cannot be held liable for any damage to the household
appliances.
For the aforementioned reasons, we recommend not
placing furnishings, furniture, etc. under the indoor
unit.
Any modication to the appliance that is not explicitly
indicatedinthissectionofthebookletisforbidden.
In the event of malfunctions, faults or incorrect opera-
tion, turn the appliance o and contact an authorised

Installation of gas appliances, ue
exhaust pipes and combustion air intake
pipes is forbidden in places with a re
risk (for example: garages, closed par-
kingstalls),andinpotentiallydangerous
places.
Do not install on the vertical projection
ofhobs.
Do not install in places/rooms that con-

e plugs (standard supply) are only to be used to x the indoor
unitto the wall; they onlyensureadequatesupport ifinserted cor-
rectly (according to technical standards) in walls made of solid or
semi-hollow brick or block. In the case of walls made from hollow
brick or block, partitions with limited static properties, or in any
case walls other than those indicated, a static test must be carried
outtoensureadequate mount.
is indoor unit is used to heat water to below boiling
temperaturein atmospheric pressure.
ey must be connected to a central heating system and
domestic hot water circuit suited to their performance
andcapacity.
e appliance is built to also operate in
