For use in Europe:

 This appliance can be used by 

children aged from 8 years and above and persons 

with reduced physical, sensory or mental capabilities 

or lack of experience and knowledge if they have been 

given supervision or instruction concerning use of the 

appliance in a safe way and understand the hazards 

involved. Children shall not play with the appliance. 

Cleaning and user maintenance shall not be made by 

children without supervision.

Installing the unit

  WARNING

IMPORTANT: When installing the unit, always remember 

to connect first the refrigerant tubes, then the electrical 

lines.

 

Upon receipt, inspect the product to verify that 

it has not been damaged during transport. If the 

product appears damaged, DO NOT INSTALL it and 

immediately report the damage to the carrier or 

retailer (if the installer or the authorized technician has 

collected the material from the retailer.)

 

After completing the installation, always carry out a 

functional test and provide the instructions on how to 

operate the air conditioner to the user.

 

Do not use the air conditioner in environments with 

hazardous substances or close to equipment that 

release free flames to avoid the occurrence of fires, 

explosions or injuries.

 

Our units should be installed in compliance with the 

spaces shown in the installation manual, to ensure 

accessibility from both sides and allow repairs or 

maintenance operations to be carried out. The 

unit’s components should be accessible and easy to 

disassemble without endangering people and objects.

 

For this reason, when provisions of the installation 

manual are not complied with, the cost required to 

access and repair the units (in SAFETY CONDITIONS, 

as set out in prevailing regulations) with harnesses, 

ladders, scaffolding or any other elevation system will 

NOT be considered part of the warranty and will be 

charged to the end customer.

 

While in installation or relocation of the product, do 

not mix the refrigerant with other gases including air 

or unspecified refrigerant. Failure to do so may cause 

pressure increase to result in rupture or injury.

 

Do not cut or burn the refrigerant container or pipings.

 

Use clean parts such as manifold gauge, vacuum 

pump, and charging hose for the refrigerant.

 

Installation must be carried out by qualified personnel 

for handling the refrigerant. Additionally, reference the 

regulations and laws.

 

Be careful not to let foreign substances (lubricating 

oil, refrigerant other than R32, water, etc.) enter the 

pipings.

 

When mechanical ventilation is required, ventilation 

openings shall be kept clear of obstruction.

 

For disposal of the product, follow the local laws and 

regulations.

 

Do not work in a confined place.

 

The work area shall be blocked.

 

The refrigerant pipings shall be installed in the 

position where there are no substances that may 

result in corrosion.

 

The following checks shall be performed for 

installation:

 

The ventilation devices and outlets are operating 

normally and are not obstructed.

 

Markings and signs on the equipment shall be 

visible and legible.

 

Upon leakage of the refrigerant, ventilate the room. 

When the leaked refrigerant is exposed to flame, it 

may cause generation of toxic gases.

 

Make sure that the work area is safe from flammable 

substances.

 

To purge air in the refrigerant, be sure to use a vacuum 

pump.

 

Note that the refrigerant has no odour.

 

The units are not explosion proof so they must be 

installed with no risk of explosion.

 

This product contains fluorinated gases that 

contribute to global greenhouse effect. Accordingly, do 

not vent gases into the atmosphere.

 

For installation with handling the refrigerant(R-32), 

use dedicated tools and piping materials.
