as soon as you take it out of its packaging. If necessary, consult the
Agency that sold you the equipment.

All VOKÈRA equipment shall be installed by competent persons. The

installation must conform to current Legislation and the instructions in
this booklet.

These units must comply with their intended use, pursuant to their

performance characteristics.

VOKÈRA will not accept any liability for damages to property, people or

animals because of installation, calibration and maintenance mistakes
or erroneous usage of the equipment.

In case of abnormal operation, or leaks of liquids or refrigerant gases,

position the main switch of the system in the “off” position and close
the stop taps. Call VOKÈRA’s Technical Service or other professionally
qualified personnel immediately. Do not try to repair the unit.

This booklet must be kept carefully as it is an integral part of the

equipment and must ALWAYS be present, including in case of sale
of the equipment to another owner or user, or of transfer to another
system. Should the manual get damaged or lost, please ask for a
duplicate manual from the VOKÈRA’s Technical Service.

Repairs or maintenance actions must be carried out by VOKÈRA’s

Technical Service staff or other skilled staff, pursuant to the provisions
of this publication. Do not modify or tamper with this equipment, as
doing so might cause dangerous situation, for which the manufacturer

In the installation and/or maintenance operations please adopt the

appropriate attire and accident prevention devices. The Manufacturer
waives all and any responsibility for failure to observe the safety and
accident prevention regulations from time to time in force.

Comply with the legislation in force on the country of deployment

with regard to the use and disposal of packaging, of cleaning
and maintenance products and for the management of the unit’s
decommissioning.

Pursuant to the EC standard n. 842/2006 on certain fluorinated

greenhouse gases, it is mandatory to declare the exact quantity of
refrigerant present in the installed system. This piece of information can
be found on the technical tag attached to the outdoor unit.

This unit contains fluorinated greenhouse gases covered by the Kyoto

protocol. Maintenance and disposal activities must be carried out
exclusively by skilled personnel.

The units contain refrigerant gas: handle them carefully, to avoid

damaging the gas circuit.

Fundamental safety rules

Titolo_fittizio

Do not allow children or unassisted disabled people to use the unit.
Do not open the access covers and carry out technical or cleaning

activities before disconnecting the unit from the power grid by
positioning the system’s main switch in the “off” position.

It is forbidden to modify the safety or regulation devices without the

authorisation and directions of the manufacturer.

Do not stand, sit and/or place objects on the unit.
Do not pull, detach or twist the electrical wires coming out of the unit,

even when the unit is disconnected from the power grid.

Do not spray or throw water directly on the unit.
Do not dispose of, abandon or leave the potentially hazardous

packaging materials within the reach of children.

It is strictly forbidden to touch any moving parts, interfere with them or

introduce pointed objects through the grids.

Description

AriaPRO

The product is characterised by:

 PAM and PWN modulation DC-INVERTER control, which allows the

compressor to modulate its performance continuously from 30% up to
120%, guaranteeing high energetic standards at all moments.

 Pre-painted sheet metal cabinet.
 Revolving TWIN ROTARY-type compressor mounted on antivibrating

mounts and placed in a special compartment.

 Electronically controlled variable speed fan, ensuring a highly silent

operation.

 AISI 316 stainless steel plate heat exchanger, utilities side, insulated

with closed cell anticondensation lining, complete with resistor and
differential pressure switch.

 Exchanger made of copper pipes and aluminium corrugated fins.
 Safety devices such as pressure switches, sensors, specific automatic

switches and main door-blocking switch.

 Phase monitor.
 Integrated hydronic module, quickly installed with the help of a few

external components.

 Micro-processor electronic control regulation performance
 Climate control.

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.

Operating conditions

With models 004 - 006, min. outdoor air temperature must be +5°C if

operating in cooling mode.

For the optimum working of the heat pump when producing hot water

in summer operation, outdoor air temperature should not exceed
30°C.

When outdoor air temperature exceeds 30°C, hot water production

may be limited according to the settings of the safety devices in the
equipment.

For technical activities, please refer to the technical tag mounted on

board the machine

It is forbidden to work outside of the working field
