▶▶▶1. INTRODUCTION

▶▶1.1. INTRODUCTION

The manual is intended for the end user only in regard to operations that can be performed with closed panels. The operations that require to open doors or panels with tools must only be performed by expert personnel. Each appliance must be connected to the power supply via a cable with a power plug supplied with the unit. For maintenance operations, the power plug must always be disconnected to allow the operator to intervene in safe conditions.

If assistance or spare parts are required, read the identification plate located outside of the unit to identify the appliance (model and serial number).

▶▶1.2. GENERAL SAFETY RULES

The purpose of the manual and of the entire documentation supplied is to allow both the installer and operator to correctly perform the installation, start-up and maintenance of the equipment, without causing damage to the personnel in charge and to the unit.

Each appliance is subject to a risk assessment carried out in compliance with current legislation, which defines the necessary actions and implements the protective measures required to achieve the risk reduction objectives.

All activities regarding the operation and maintenance of the unit must be performed:

▶ Only by properly trained people, who must implement safe working practices and use the personal protective equipment appropriate to the specific task performed, based on their specific qualification.
▶ Only by properly trained people who have read and fully understood the manuals, technical documents and safety documents.

▶Use of the appliance must not be allowed to anyone who is not adequately trained and skilled.

This manual, the technical documents and any security documents attached must be read and stored for the entire lifespan of the appliance:

⚠️ CAUTION: This appliance is designed for use in an indoor environment.

⚠️ CAUTION: The unit must be connected to an electrical system that complies with local electrical safety regulations.

⚠️ CAUTION: The unit must be placed by following the dimensions and spaces required, including the minimum spaces allowed by adjacent structures.

⚠️ CAUTION: This equipment must always be connected to earth. We decline any liability for any danger or damage caused if this requirement is not complied with.

CAUTION: Sharp tools (screwdrivers, needles or the like) must not be inserted into the grids or inside any other panel opening, especially when the unit is open to remove the filter.

⚠️ CAUTION: All maintenance and cleaning operations on the unit must be performed with the power supply disconnected. Never remove the front grids or open any part of the unit without first disconnecting the plug from the socket.

⚠️ CAUTION: Do not use water to clean the unit. Use a wet cloth to clean the unit. Never spray water on the unit and its electrical components.

The equipment must always be kept in a vertical position in order to prevent accidental spillage of condensation (water) from the specific container. It is strictly forbidden to move the equip-

ment while connected to the power outlet, as the resulting vibrations and movements may cause the condensation to leak from the specific container, thus affecting the electrical parts.

The unit can only be moved after emptying the condensate tank, and in any case, it is ALWAYS REQUIRED to remove the plug from the socket before moving the appliance. Should water be accidentally spilled on the appliance, the unit must be immediately turned off and disconnected from the power supply and may only be turned on after eight HOURS/TAC have elapsed.

CAUTION: The equipment contains R1234yf refrigerant: this gas is flammable. The amount of charge is indicated in the data table of this user manual.

Warning, the refrigerant is odourless.

Do not use any means to accelerate the defrosting process or for cleaning other than those recommended by the manufacturer.

The appliance must be placed in a room that does not have ignition sources continuously in operation (e.g. open flames, a gas appliance while running or an electric heater running).

Do not drill holes into or burn the appliance.

▶▶1.3. PERSONAL PROTECTIVE EQUIPMENT

Use the following personal protective equipment during unit use and maintenance operations:

⚠ CLOTHING: Those who carry out maintenance or work on the unit in environments with slippery floors must wear safety shoes with non-slip soles.

⚠️ GLOVES: Appropriate gloves must be worn during cleaning and maintenance operations. When refilling the refrigerant gas, the use of appropriate gloves is mandatory in order to prevent the risk of freezing.

⚠️ MASK AND GOGGLES: Masks to protect the respiratory tract and safety goggles to protect the eyes must be worn during cleaning and maintenance operations.

▶▶1.4. GENERAL SAFETY RULES

The following safety signs, which must be respected, are affixed on the unit:

Read the user manual.

Read the technical manual.

Electric shock hazard.

Flammable material hazard.

⚠️ CAUTION: It is strictly forbidden to remove the safety signs on the units.

▶▶▶2. GENERAL DESCRIPTION OF THE UNIT

(PIC. 1)

(PIC. 2)

A. Ambient air inlet.

B. Ambient air inlet.

C. Hot air outlet.

D. Cold air outlet.

This appliance allows you to control the ambient temperature and relative humidity. The available functions are cooling, dehumidification and ventilation.

For correct ambient climate control, it is necessary to adapt the appliance and select the correct desired operating mode via the control panel, considering that the lower grids (front and rear) draw in the ambient air, whereas the upper grids release air into the environment [the upper/front grid (D PIC. 2) releases cold air, whereas the upper grid (C PIC. 2) releases hot air].

Refer to the “CONTROL PANEL” paragraph for the operating modes.

▶▶2.1. REFRIGERANT CIRCUIT

The refrigerant gas used in these units is R1234yf. The refrigerant circuit is built in compliance with current standards.

Flammable material hazard.

This unit is hermetically sealed and contains fluorinated gas R1234yf GWP (R1234yf) = 4.

▶▶▶3. PRELIMINARY OPERATIONS

▶▶3.1. REMOVAL OF THE PACKAGING AND ASSEMBLY

(PIC. 3)

Remove the packaging taking care not to damage the unit. Dispose of the packaging products (wood, plastic, cardboard), taking them to the specialised collection or recycling centres (follow the local regulations in force).

CAUTION: Assemble the appliance, with the adequate air outlet (1 or 2-way outlet, depending on the model), handles, wheels, cord reel and all the relevant nuts and bolts, before operating it.

NOTE: Correct operation requires the appropriate air outlet to be installed, according to the actual requirements (depending on the model).

▶▶3.2. INSPECTION

All units are factory assembled and wired (except for certain components). Upon receiving the unit, it must be immediately and thoroughly inspected, checking that it has not been damaged during transport or that no parts are missing.
