Installation; General - MAXA i-290 0106 Installer Manual

No smoking near the unit.
Transport and storage must be performed in accordance with the national regulations in force. Specifically, according to ADR provisions, the
total maximum quantity by transport unit in terms of net mass for flammable gases is 333 kg. In addition, for road transport, use vehicles that
are preferably open or equipped with a ventilation system and operated by trained personnel.
For prerequisites on the transport by sea of equipment loaded with flammable refrigerant refer to the International Maritime Dangerous Goods
Code (IMDG), and for transport by air check the regulations prescribed by the International Air Transport Organisation (IATA).
If it is necessary to store the unit for medium to long periods, please observe the following precautions:
• if storage is in a closed location, leave the machine in a dedicated place that is always dry, cool, well ventilated and protected from possible
ignition sources, direct sunlight or other heat sources. It is also recommended to use one flammable gas detection sensor per 36-40 m2.
Always refer to national regulations;
• if storage is carried out in an open area, observe the minimum safety distances from drains, cisterns, sewers and other underground areas,
in accordance with the national regulations in force;
• do not remove covers and packaging;
• ensure that all panels are correctly mounted;
• do not obstruct the openings and holes made in the machine panels;
• avoid cleaning the unit with aggressive detergents or chemicals;
• it is advisable to remove any heating water inside the unit to prevent possible corrosion or, in cold climates, damage to components caused
by freezing.
CAUTION: When transporting and storing the unit, beware of possible refrigerant gas leaks that could start a fire.

5. INSTALLATION

CAUTION: All the operation described below must be done by QUALIFIED PERSONNEL ONLY (IEC 60335-2-40 Annex HH). Be-
fore any operation on the unit, make sure that power supply is disconnected. When trasporting and storing the unit, beware
of possible refrigerant gas leaks that could start a fire.
5.1 GENERAL
When installing or working on the refrigeration circuit, it is necessary to scrupulously comply with the regulations in this manual, observe the
instructions on the unit and in any case apply all necessary precautions. Failure to comply with the instructions may lead to dangerous situations.
After receiving the unit, immediately check its integrity. The unit left the factory in perfect condition; any damage must be
immediately reported to the carrier and recorded on the Delivery Note before signing it.
The company must be informed, within 8 days, of the extent of the damage. The customer should prepare a written statement of any severe
damage.
The units are designed to be installed outdoors. Under no circumstances should the outdoor ambient temperature exceed
46°C when the unit is not in operation. Above this value, the unit is no longer covered by current pressure equipment safety
regulations.
The installation place must be without any fire risks. All necessary measures must therefore be taken to prevent the risk of
fire at the installation site (see Chapter 5.5 for more details). The device must not be placed in the vicinity of open flames,
ignition sources or heat sources.
The wall of the buildings near the unit must have an adequate fire resistance class, in order to contain any fire that may
develop inside the rooms. However, it is recommended to place a fire extinguisher near the unit.
The unit must be installed in order to allow maintenance and repair. The warranty does not cover costs for platforms or
other lifting equipment needed for any interventions.
All the maintenance operations and tests must be done by QUALIFIED PERSONNEL (IEC 60335-2-40 Annex HH). All equipment
used during maintenance operations must be compatible with the refrigerant gas R290.
Before any operation on the unit, make sure that the power supply is disconnected and cannot be switched on again acci-
dentally. After disconnecting the power supply from the unit, wait at least 5 minutes before performing any operation on the
machine to allow the condenser to discharge.
Do not use equipment to speed up the defrost process or for cleaning except for those recommended by the manufacturer.
