CONTROL AND
MAINTENANCE.
- make sure the central heating system is filled
with water and that the pressure gauge indicates
a pressure of 1÷1.2 bar;
- make sure that the air vent valve cap (if present)
is open and that the system is well deaerated;
- check the activation of the main switch located
upstream of the indoor and/or the outdoor
units;
- check tightness of water circuits;
- check the correction of the electric and hydrau-
lic connections;
Even if just one single safety check provides a
negative result, do not commission the system.
N.B.: the 8 l DHW expansion vessel is connected
to the hydraulic unit via a flexible hose; in the
event of maintenance it is possible to temporarily
move the vessel by unscrewing the lock nut that
fastens it to the relative supporting bracket.
3.1 EXTERNAL TEMPERATURE PROBE.
An external probe (optional) can be connected
to the Magis Pro V2 or Magis Combo Plus V2
indoor units (see the relevant instruction booklet
for the connection).
For the Victrix Hybrid Plus, the external probe
is supplied as standard on the outdoor unit and
the optional external probe cannot be connected
to the indoor unit.
The correlation between the system flow tem-
perature and external temperature is determined
by the parameters set in the assistance menu
"Central heating thermoregulation" as shown in
the relative instruction booklet.
3.2 ANNUAL MAINTENANCE:
- Check the integrity of the storage tank unit
magnesium anode.
- Check tightness of the assembly elements
(screws, bolts, plugs, structure elements, etc.).
- Check that the system is in good condition.
- Check for water leaks or oxidation from/on the
fittings.
- Perform a visual check to make sure that
the safety and control devices have not been
tampered with and in particular, the regulator
probe, the expansion vessel and the safety valve.
- In case of hard water, it is advisable to remove
the lime scale from the storage tank unit at least
once a year.
- Service the indoor and outdoor units according
to the guidelines in the relative instruction
booklet.
Vent
Any air present in the system must be bled:
- upon start-up (after filling)
- if necessary, e.g. in the event of breakdown.
Replacing the anode
The anode (c2) present in the storage tank must
be replaced every year, as shown below.
3.3 DECOMMISSIONING.
In the event of permanent system shutdown,
contact professional staff for the procedures and
ensure that the electrical, water and gas supply
lines are shut off and disconnected and that the
solar collector (if present) is covered.
In the case of Magis Pro V2 and Magis Combo
Plus V2, Pump-down must be carried out before
disconnecting the indoor unit.
