seepage or flooding with possible damage to the home and other property.

– Insulate the piping to avoid condensation.

General Details

– Always use the specified cables for all electrical work. Connect the cables securely and secure them

in a stable manner to prevent the terminals from being damaged by external forces. Incorrect electrical

connection may cause overheating conditions and may result in fire and electrocution.

– Install the electrical cables making sure that they are not taut. Otherwise, they could break or overheat

causing smoke or fire.

– The cables must be arranged so that the control board cover can close properly. If the control board cover

is not closed properly, corrosion may occur and the connection points on the terminals may become hot,

ignite or cause electric shock.

– Always disconnect all power supply circuits before touching the terminals for any reason.

– It is advisable to install a Class B or F differential magnetothermic circuit breaker on the power supply line

of the appliance.

– For electrical work, comply with the provisions of the national electrical code, local regulations, current

regulations and the requirements contained in the installation manual. It is necessary to use an independent

circuit and a single power supply socket. Do not connect other appliances to the same electrical outlet.

Insufficient electrical capacity or faulty electrical installation may cause risk of electric shock or fire.

– Incorporate in the wiring an omnipolar isolator switch with a separation distance of at least 3mm between all

poles and a residual current device (RCD) with a value greater than 10mA. Observe the domestic regulations.

– Replace the fuses only with others of the same value and technical characteristics.

– Install the appliance and its power cables at least one metre away from other electrical equipment in order

to avoid interference or noise.

– The appliance must be stored in such a way as to prevent any mechanical damage.

CAUTION DANGER

– When connecting refrigerant piping,keep substances or gases other than the specified refrigerant from entering

the unit. The presence of other gases or substances can reduce unit performance and cause an abnormal

increase in pressure in the refrigeration cycle. This can lead to explosion hazards and resulting injuries.

– Install the unit on a stable stand that can support its weight. If the chosen stand cannot support the weight of

the unit, or if the installation is not performed correctly, the unit may fall and cause injury and serious damage.

– Do not pierce or ignite the appliance.

– The appliance must be placed in a well-ventilated room whose dimensions correspond to those specified

for operation.

– The product must be installed with earthing in accordance with the law to avoid the risk of electrocution.

Do not connect the earth cable to gas or water mains, lightning rods or phone earth cables.

– Install an earthing connection switch. Failure to install this can result in electric shock.

– Do not operate the appliance if the protections have been removed.

– Do not install the unit:

- in a location that can be exposed to combustible gas leaks. Any accumulation of combustible gas around

the unit may cause a fire hazard;

- near the coast (except in the case of corrosion resistant models);

- near a source of hot water due to the presence of caustic gas in the air;

- in the presence of strong electromagnetic waves;

- in the presence of significant voltage flicker;

- in the presence of acid or alkaline liquid that evaporates;

- in the presence of flammable materials or gas.

– Wear the required PPE (protective gloves) during installation and maintenance. High pressure piping poses

a risk of burns during operation.

– Measure the insulation resistance and make sure it is at least 1M Ωonce the wiring work is done.
