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

Installation, use and maintenance manual – Gitié ACAY

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 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.

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

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

and operative codes. The appliance is monitored and pro-

grammed by interacting with the display and the knob.

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
