1.1 DESCRIPTIONOFTHEPRODUCT.
Magis HerculesPro 4-6-9isa heat pump consistingof:
- UI MHP BP indoor unit (hereinaer called, indoor unit or UI
MHP).
- Audax Pro 4-6-9 V2 outdoor condensing unit (hereinaer re-
ferred toasoutdoorcondensing unit orAudax Pro 4-6-9V2).
Magis Hercules Pro 4-6-9 is perfectly operational only if the two
units arecorrectlypowered andinterconnected.
eUI MHPindoorunit wasdesigned solelyforoorinstallation
for heating and air conditioning and to produce domestic hot wa-
terfordomestic useandsimilarpurposes.
For normal operation is must be paired with one of the following
outdoorcondensingunits:
- AudaxPro4V2outdoor condensing unit;
- AudaxPro6V2outdoor condensing unit;
- AudaxPro9V2outdoor condensing unit;
Accordingly, it is necessary to comply with all of the rules regard-
ing safety andtheuseof bothappliances.
1.2 INSTALLATIONWARNINGS
Operatorswhoinstallandservicetheap-
pliance must wear the personal protec-
tive equipment required by applicable
law.
e place of installation of the appliance and relative
Im mer ga s ac c e ss or ie s mu st have su it abl e feat u re s (t ec h-
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, peri-
odic,routineandspecialmaintenance);
- removal (to outdoors in the place for loading and
transporting the appliances and components) as well
as the eventual replacement of those with appliances
and/orequivalentcomponents.
Installation must be carried out according to regulation
standards, current legislation and in compliance with
local technical regulations and the required technical
procedures.
e appliance operates with R32 refrig-
erantgas.
isgasisODOURLESS.
Paytheutmostattention
Strictlyfollowtheinstructionhandbook
oftheoutdoorcondensingunitbeforein-
stallation and any type of operation on
thecoolingline.
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).
e manufacturer declines all liability in the event of
damage caused by appliances removed from other sys-
tems orforanynon-conformities withsuch equipment.

– Do not remove the fuses while the unit
ison.
– Donotunplugtheunitwhileitison.
It is recommended to install the outlet
high up. Lay the cables in such a way that

is indoor unit is used to heat water to below boiling
temperatureinatmosphericpressure.
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
