deactivate the appliance immediately (if permitted and if no condition of dan ger •
exists) by starting the shutdown cycle via the CCP (or DDC or consent switch) and
waiting for it to terminate (approximately 7 minutes);
disconnect the appliance from the gas and electricity mains, cutting o gas supply •
by means of the appropriate valve and the power supply by means of the external
circuit breaker provided by the electrical system installation technician on the ap-
propriate panel.
Correct routine maintenance ensures the eciency and good operation of the appli-
ance over time.
Carry out maintenance operations according to the instructions supplied by the
manufacturer.
For maintenance of the appliance’s internal components, contact a Robur TAC
or qualied technician; for other maintenance requirements, see Paragraph 6.2
MAINTENANCE → 63.
Any repair of the appliance must be carried out by an authorised Robur Technical Assist-
ance Centre (TAC), using only original parts.
Failure to observe the indications given above may compromise the operation and safety
of the appliance, and may invalidate its guarantee, if active.
If the appliance is to be disposed of, contact Robur S.p.A. for its correct disposal.
If the appliance is to be sold or transferred to another owner, ensure that this “Installa-
tion, user and maintenance manual” is handed over to the new owner and installation
technician.
2.2 NOTES ON OPERATION OF THE APPLIANCE
The appliance uses the water/ammoniac absorption thermodynamic cycle (H
2
0 – NH
3
) to
produce hot water, using atmospheric air as renewable energetic source.
The water/ammoniac thermodynamic cycle used on the unite GAHP-A, is implemented
in a hermitically sealed circuit which has no mechanical unions and is checked directly
by manufacturer to ensure the perfect seal of all joints, thus making refrigerant top ups
completely unnecessary.
Description and general characteristics
The air-water gas absorption heat pump GAHP-A is available in the following versions:
Version • HT: optimised for high temperature heating systems (radiators, fan coils);
it produces hot water to +65°C for heating purposes and up to +70°C for sanitary
hot water.
Version • LT: optimised for low temperature oor heating systems; it produces hot
water to +55°C for heating purposes and up to +70°C for sanitary hot water.
The GAHP heat pump can be controlled with the Direct Digital Control (vedere Figura 5.3
Direct Digital Control (DDC) → 41) or with a switch on the consent circuit.
During operation, combustion products are exhausted via the discharge terminal at the
left side of the appliance (see Figure 2.1 Size (Standard ventilation) → 14 or Figure 2.2
Size → 15). The fumes outlet must be connected to a ue (for further details, see Para-
graph 4.7 EXHAUSTING THE COMBUSTION PRODUCTS → 35).
The appliance is powered with 230 Vac 1N - 50 Hz.
