Titolo_fittizio

The AriaPRO range units are designed for the production of refrigerated
water for air conditioning, heated water for heating and sanitary hot water
for homes, residential units, etc., and are used together with terminal units
for small and medium systems.
They are designed for outdoor installation, so their constituent materials
were chosen for this specific requirement.

Identification

Technical Tag

The technical tag shows all technical and performance data of the

unit. Should the tag get lost, please ask for a duplicate tag from the
VOKÈRA’s Technical Service.

Any tampering with, the removal or the lack of the Technical Tag or of

any other element whose absence prevents certain identification of
the product makes it more difficult to install and maintain the product.

Installer

Product delivery

Preliminary instructions

We suggest to take the equipment out of its packaging only when it

has been placed in position at the installation point.

Carefully remove any adhesive strips positioned on the unit.
Do not dispose of, abandon or leave the potentially hazardous

packaging materials within the reach of children.

Scope of supply

Also supplied:

 Installer manual
 External probe
 Barcode labels
 Control panel
 Strain relief (size 015M only)
 List of spare parts

The supplied accessories are positioned inside the electrical panel.

 Cable gland
 Drain discharge pipe

Handling and transportation

Titolo_fittizio

The unit must be handled by skilled technicians, appropriately

equipped and with the appropriate tools to manage the unit’s weight in

compliance with the accident prevention regulations.
When handled, the unit must always be kept in a vertical position.
The weight of the equipment is off balance towards the compressor.
If the unit is lifted, use pipes with a diameter and thickness appropriate

for the weight of the unit.
Use all the lifting points shown.

Access to inner parts

Titolo_fittizio

- Remove the access panel.

- Loosen the fastening screw.

Installation

Preliminary instructions

The place of installation must be determined by the system’s designer

or by an expert in the field and must take into account the technical
requirements and the current standards and legislation.

We suggest to avoid:

 The placement in service ducts and/or hopper windows
 Obstacles or barriers that cause a recirculation of the expelled air
 Places with aggressive atmospheres
 Small places where the unit’s noise level can be enhanced by

reverberation and resonance.

 Placement in corners, where dust, leaves and other debris may easily

deposit ma reduce the efficiency of the unit, through obstruction of the
air flows.

 The airflow from the unit can penetrate in the inhabited rooms through

doors or windows, creating discomfort.

 That the airflow from the unit is opposed by a contrary wind.

The units must:

 Be placed on a level surface able to support their weight.
 Be placed on a sufficiently rigid floor slab that does not transfer vibrations

to the rooms below or next door.

 It is suggested to place a rubber plate between the slab and the unit, or

to use anti-vibrating mounts appropriate for the unit’s weight.

The unit must be installed exclusively indoors.
If there are several units placed side by side on the bank side, the

required distances must be summed.

Provide for lifting of the unit from the floor:

 20mm without conveying of condensation discharge
 90 - 100 mm to allow the conveying of the condensation discharge

If the unit is installed in areas subject to heavy snowfall, it shall be

necessary to avoid the unit being directly exposed to it.

Hydraulic connections

Preliminary instructions

The choice and installation of system components is left to the skilled

installer, who shall operate pursuant to the best practices and the
legislation from time to time in force.

Check that the pipes do not contain stones, sand, rust, debris or other

extraneous bodies that might damage the system.

It is appropriate to create a by-pass of the unit to make it possible to

wash the pipes without having to disconnect the unit.

The connection tubes must have the appropriate diameter and must

be supported, so as not to rest their weight on the unit.

Mandatory items:

 Install a filter whose dimensions are appropriate for the impurities

present in the water entering the unit.

 Install a flow meter for liquids, to be dimensioned and calibrated

according to the system’s hydraulic characteristics.

 Install air venting valves in the highest points of the pipes.
 Install flexible elastic joints to connect the pipes.
 The flow meter must be positioned halfway through a stretch of

horizontal pipe with a length of at least 1 metre.

The system’s water content must prevent instabilities in the operation

of the refrigerating circuits.

Systems charges with anti-freezing agents or subject to special

regulations require the use of water disconnectors.

Failure to install filters, flow meter and anti-vibrating mounts can cause

obstruction, breakage and noise issues, for which the manufacturer
waives any liability.

Check charge losses from the unit, the system and any other in-line

mounted accessories.

The water flow must be maintained stable during operation.
The sealing of threads must be obtained using hemp and green paste.

Do not use Teflon when the unit contains anti-freeze liquid.

Do not use the heat pump to treat the water used by industrial

processes, in swimming pools or in the house. In all these cases, an
intermediate heat exchanger is required.

Condensate discharge connection

With conveying

Connect a drainage tube to the connector on the collector tray and run it
towards and appropriate discharge area.

Without conveying

- The drainage capacity increases if the pre-cut holes in the base are
open.

In case of installation in very cold areas or areas subject to heavy

snowfall, where freezing out is a possibility, foresee appropriate
antifreeze systems.

emptied before being recharged, and the refrigerant must be
recovered.

Any gas leaks indoors can generate toxic gases if they come into

contact with naked flames or high temperature bodies, in case of
leaks, please air the rooms thoroughly.

Do not charge the refrigerating circuits with a different refrigerant from

the prescribed one.

Do not use oils that are different from the prescribed one. The use of

different oils may seriously damage the compressor.

Do not use oxygen or acetylene or other flammable or poisonous

gases in the refrigerating circuit, as they can cause explosions.

Operating conditions different from the nominal ones may yield values

that differ considerably.

Compressor

The compressor is installed on the unit already charged with oil and
sealed.
In case of breakages, if the compressor can be repaired, use only original
ester oil.

Do not use oils that are different from the prescribed one. The use of

different oils may seriously damage the compressor.

Refrigerant charge

Proceed as follows:

- Empty and dry the whole refrigerating circuit using a vacuum pump
connected to both the low pressure and high pressure ports, until the
value displayed on the vacuum gauge is about 10 Pa.

- Wait for a few minutes and check that such value does not go up again
to over 50 Pa.

- Connect the refrigerant gas cylinder or a charging cylinder to the low
pressure line port.

- Charge the required quantity of refrigerant gas, as shown in the unit’s
technical tag.

In case of partial leak, the circuit must be completely emptied before

being recharged.

The refrigerant must be charged into the unit only in its liquid state.

Adapting the heating curve.

The Control Panel adapts the water’s set-point to the actual temperature
in the room, as measured by the Control Panel’s user interface, so as
to maintain a constant temperature in the room, for comfort and energy
saving.
For this reason the actual water temperature may vary as against the
calculated set point one, by +/- 5°C.
The user can interact with this function increasing or decreasing teh set­point, regulating the water temperature through parameter 4, as shown in
the picture.

Correction of room temperature

The user can correct the temperature measured by the Control Panel in
case of mistakes due to placement.
Through parameter 13 (see parameter’s functions table) it is possible to
correct teh temperature by +/-5°C.

Abnormal operations

Anomalies warnings.

Preliminary instructions

In the presence of operating abnormalities, the unit is secured and

blocked.

Safety block can occur randomly.
Wait for at least 10 minutes before restarting the unit.
Any repetition of the abnormal operation requires an accurate check of

the unit’s components.

Before resetting, it is necessary to remove the cause of the anomaly.
Abnormal operations are notified by the Control Panel with codes

comprising letters and numbers, which alternate with the system’s
backflow temperature.

Part of the alarms resets automatically, while others require a manual

reset by the Technical Service.

Troubles can be diagnosed by Leds on mother circuit board.
