SAFETY INSTRUCTIONS

• READ THE INSTRUCTION MANUAL CAREFULLY BEFORE CARRYING OUT ANY WORK ON THE EQUIPMENT.
• The unite is factory precharged with dry nitrogen or with dry air to prevent the ingress of any water vapour. Before removing
the plugs from the inlet and outlet connections for installation, discharge the nitrogen by means of the needle valve on the
inlet manifold
• The condenser contains gas above atmospheric pressure: tampering with connections or pipework can cause leakage of
compressed gas
• The temperature of the inlet pipe to the condenser can rise above 70°C and therefore presents the risk of burns
• INSTALL THE CONDENSER IN A POSITION WHICH IS INACCESSIBLE TO UNAUTHORISED PERSONNEL: the fins
of the heat exchanger are made from thin aluminium sheet and can cause cuts in the event of accidental contact.
• The unite contains live electrical parts and rotating devices: before carrying out any work on the electrics or on
the fan, isolate the unit (turn optional isolator to position 'O')
• All service and maintenance operations which require access to the inside of the unit while it is in operation must
be performed by qualified and experienced personnel who are aware of the precautions which must be taken.
• In the event of fire, water and other conductive substances must not be used to put out the fire near live electrical com-
ponents. This warning must be displayed on notices in the unit installation location.
• If the refrigerants used come into contact with fire they decompose, forming acids and other irritants.
The smell of these substances, even at concentrations below danger levels, gives enough warning to allow evacuation of
the area at risk.
Make sure that the power supply voltage corresponds to the value shown on the data plate.

UNIT DESCRIPTION

GENERAL DESCRIPTION

Remote condensers / Dry cooler with axial-type fan(s) for outdoor installation, fully pre-assembled, assembled and tested in the factory.
Installation may be vertical with a horizontal air outflow or, using special brackets, horizontal with an upward air outflow.
The very low noise, adjustable-speed fans are excellent for use in both technological and civil applications.
The unite in the BRC/BRE/BDC range operate with a single-phase 230/1/50 power supply totally independent and separate from the indoor unit
ACCURATE. These condensing units are therefore also suited for use without being directly connected to indoor units.
HOUSING: designed to allowed easy access to internal components, is made from smooth finish aluminium/magnesium and, in some case, from
prepainted galvanized sheet steel, and it:
• offers hight corrosion strenght and impact resistence;
• is resistant at low temperatures;
• is non toxic;
• does not produce polluting debris;
• is complrtely covered in a protective plastic film.
ELECTRIC FANS of an axial type, statically and dynamically balanced on two levels, with blades in an inoxidable material and external rotor motor
suitable for adjusting the speed, all mounted on a metal supporting grid in conformity with safety regulations.
The motors are to VDE 0530-12.84.
The protection rating is IP54 to DIN40050
CONDENSING COIL: the combination of innovative corrugated fins with the use of smooth pipes on the exchanger ensures excellent heat transfer
with a minimum amount of fluid.
The heat exchangers consist of aluminium fins and copper pipes with a nominal diameter of 3/8" in the 500 mm diameter range of fans and with a
nominal diameter of 1/2" in the 630 mm diameter fans.
The pitch between the fins is 2.1mm
REFRIGERANT/ HYDRAULIC CIRCUIT CONNECTIONS are arranged along one side of the unite and are to be welded for safe connection that
prevents any fluid leak.
ISOLATING SWITCH, fcontained in an electric box with protection rating IP54, with switch control accessible from the outside and connecting
terminals.
FANS SPEED REGULATOR; units BRC/BRE/BDC, are not provided with integrated fans speed regulator per standard. However, CLIMAVENETA
can provide such fans speed regulator as OPTIONAL, by installing it directly inside the indoor unit ACCURATE. BRC/BRE/BDC fans in fact are
suitable to be regulated from a speed regulator.
