The HRC

Heat Pump uses R290 refrigerant fluid. Given the
flammable nature of the fluid, any work on the refrigerant circuit
must be done with appropriate materials and by conforming
to all regulations in effect. In case of handling of fluid (recovery,
evacuation or refilling), the appliance must be switched off.
Do not smoke or light any flame (e.g. lighter, blowtorch) when
handling refrigerant fluid. if work must be carried out on the
refrigerant circuit using a flame (blowtorch) the refrigerant circuit
must first be evacuated and replaced with a nitrogen atmosphere.
1.3 - Delivery terms and conditions
In general, the material is transported at the recipient’s own risk.
It is important to verify that all of the elements have been
received and that no damage has been sustained during
transport upon receipt of the appliance and before beginning the
installation procedures.
1.4 - Storage and transport
Admissible storage and transport temperatures of the appliance
are between -20°C and +60°C.
1.4.1 - General information
The appliances must be stored and transported packaged and
on their wooden pallets, in a vertical position, and completely
empty of water.
1.4.2 - Transporting with a forklift truck
When transporting with a forklift truck, the Heat Pump must be
on its wooden pallet.
When moving the Heat Pump do not lower or raise the unit
suddenly as the Heat Pump can easily lose its equilibrium. The Heat
Pump should be suitably secured to prevent it from tipping.
The Heat Pump is designed to be transported with a pallet jack.
2.1 - Standard configuration
2 - INTRODUCTION
The ensemble is composed of an exterior unit (Monoblock high
temperature Heat Pump to be installed outdoors
exclusively
)
and of an interior unit (Pilot, to be installed indoors
exclusively
)
connected together through a hydraulic connection and a
communication bus.
The air to water Heat Pump, draws calories from the exterior air
and transfers them to the heating water circuit with high energy
efficiency.
The Pilot ensures the regulation and hydraulic distribution of the
installation.
The pilot ensures the supply of water flow from the Heat Pump. It is
to be installed between the decoupling tank and the Heat Pump.
The tank ensures the hydraulic decoupling between the the Heat
Pump and the heating circuit(s).
The Pilot is delivered pre-configured for the heating of a radiator
circuit controlled by a room temperature thermostat from the
Heat Pump alone.
In the case of connection to a back-up boiler, it is used to load the
decoupling tank directly.
Note :
The Heat Pump is exclusively designed for heating purposes.
It cannot be used for cooling.
2.2 - Operation
The Heat Pump is a closed and pressurised system in which the
refrigerant serves as the medium for transferring energy.
The evaporator (4) is a cooling exchanger which draws calories
from the air.
The humidity in the air condenses on contact with the cold
surface, and forms condensation (evacuation in (8)).
The capacitor (5), a plated ehat exchanger which is hydraulically
linked to the heating installation (7),
via the Pilot, enables to heat the water in the heating circuit, and
in turn enables the heating of the building.
