III WARNINGS
III.1 GENERAL AND SAFETY WARNINGS
Installer's qualications
Installation must exclusively be performed by a qualied
rm and by qualied personnel, with specic knowledge
on heating, cooling, electrical systems and gas applianc-
es, in compliance with the laws in force in the Country of
installation.
Declaration of conformity
Upon completing installation, the installing rm shall
issue to the owner/client the appliance's workmanlike
conformity declaration, according to national/local reg-
ulations in force and the manufacturer's instructions/
provisions.
Misuse
The appliance must only be used for the purposes for
which it has been designed. Any other use is deemed
hazardous. Incorrect use may aect operation, duration
and safety of the appliance. Adhere to the manufactur-
er's instructions.
Hazardous situations
Do not start the appliance in hazardous conditions, such
as: gas smell, problems with the plumbing/electrical/gas
system, parts of the appliance under water or damaged,
malfunctioning, disabling or bypassing control and safe-
ty devices.
In case of danger, request intervention by qualied per-
sonnel.
In case of danger, switch o the electrical power and gas
supplies only if this can be done in total safety.
Warnings

III
Do not entrust children, persons with physical, sensory
or mental disabilities or persons with poor knowledge
and experience with use of the appliance.
Gas component tightness
Before performing any operation on gas ducting compo-
nents, close the gas valve.
Upon completing any procedure, perform the tightness
test according to regulations in force.
Gas smell
If you smell gas:
Do not use electrical devices such as telephones, mul-
timeters or other equipment that may cause sparks next
to the appliance.
Shut o the gas supply by turning the valve o.
Switch o the power supply via the external disconnect
switch in the power supply electrical panel.
Use a telephone away from the appliance to ask for inter-
vention from qualied personnel.
Poisoning
Ensure the ue gas ducts are tightness and compliant
with the regulations in force.
Upon completing any procedure, ensure components
are tightness.
Moving parts
The appliance contains moving parts.
Do not remove guards during operation, and in any case
prior to disconnecting the power supply.
Burn hazard
The appliance contains very hot parts.
Do not open the appliance and do not touch internal
components before the appliance has cooled down.
Do not touch the ue gas exhaust before it has cooled
down.
Pressure vessels
The appliance has a sealed circuit classied as pres-
sure vessel, the tightness of which is tested by the
manufacturer.
Do not carry out any intervention on the sealed circuit or
on the appliance's valves.
Water-ammonia solution
The GAHP/GA unit uses the ammonia-water absorption
cycle. The water-ammonia solution is contained in the
sealed circuit. The solution is harmful for health if it is in-
gested, inhaled or comes in contact with the skin.
In the event of coolant leak keep away and disconnect
the power and gas supply (only if it is possible to do so
with no danger).
Ask for TAC intervention.

ation on appliance components.
For electrical connections exclusively use compliant
components and according to the specications provid-
ed by the manufacturer.
Ensure the appliance cannot be accidentally switched
back on.
Earthing
Electrical safety depends on eective earthing system,
correctly connected to the appliance and installed ac-
cording to the regulations in force.
Distance from combustible or ammable materials
Do not deposit ammable materials (paper, diluents,
paints, etc.) near the appliance.
Limescale and corrosion
Depending on the chemical/physical properties of the
system water, limescale or corrosion may damage the
appliance (Paragraph 3.7
p.26
).
Check system sealing.
Avoid frequent top-ups.
Chloride concentration
The concentration of chlorides or free chlorine in the
system water must not exceed the values in Table
3.2
p.26
.
Aggressive substances in the air
Halogenated hydrocarbons containing chlorine and u-
orine compounds cause corrosion. The air of the installa-
tion site must be free from aggressive substances.
Acid ue gas condensate
Discharge the acid condensate of combustion ue gas,
as indicated in Paragraph 3.11
p. 28
, in compliance
with current exhaust regulations.
Switching the appliance o
Disconnecting the power supply while the appliance
is running may cause permanent damage to internal
components.
Except in the case of danger, do not disconnect the pow-
er supply to switch o the appliance, but always and ex-
clusively act through the provided control device (DDC
or external request).
In the event of failure
Operations on internal components and repairs may
exclusively be carried out by a TAC, using only original
parts.
In the event of failure of the appliance and/or breakage
of any component, do not attempt to repair and/or re-
store and immediately contact the TAC.
Routine maintenance
Proper maintenance assures the eciency and good op-
eration of the appliance over time.
Maintenance must be performed according to the man-
ufacturer's instructions (see Chapter 7
p. 35
) and in

1.6 CONTROLS
Control device
The appliance may only work if it is connected to a control de-
vice, selected from:
(1) pre-congured DDC control
(2) external enables
1.6.1 Adjustment system (1) with pre-congured
DDC control
The main functions are:
Adjustment and control of the GAHP/GA unit and AY00-120
unit in cascade (ON/OFF mode).
Data display and parameters setting.
Hourly programming.
Climatic curve control.
Diagnostics.
Errors reset.
Possibility to interface with a BMS.
DDC functionality may be extended with auxiliary Robur devices
RB100 and RB200 (e.g. service requests, DHW production, Third
Party generator control, probe control, system valves or circulat-
ing pumps, ...).
1.6.2 Adjustment system (2) with external enables
The appliance may also be controlled via generic enable devic-
es (e.g. thermostats, timers, buttons, contactors...) tted with
voltage-free NO contacts. This system only provides elementary
control (on/o, with xed setpoint temperature), without the
important functions of system (1). Control of the cascade be-
tween GAHP/GA and AY00-120 is left to the user.
For connection of the selected device to the appliance's
electronic board please refer to Paragraph 4.4
