To fasten the unit to the floor, use M10 bolts.
Before unit commissioning, the flatness must be verified by using a laser levelling device or other similar devices. The
flatness shall not be over 5 mm for units within 7 m length.
To ensure best performance on the installation site, the following precautions and instructions must be followed:
▪
Avoid air flow recirculation;
▪
Make sure that there are no obstacles to hamper air flow;
▪
Make sure to provide a strong and solid foundation to reduce noise and vibrations;
▪
Avoid installation in particularly dusty environments, in order to reduce soiling of condensers coils.
4.3.1. Outdoor Unit Minimum space requirements
It is fundamental to respect minimum distances on all units to ensure optimum ventilation to the condenser coils.
When deciding where to position the unit and to ensure a proper air flow, the following factors must be taken into
consideration:
▪
avoid any warm air recirculation.
▪
avoid insufficient air supply to the air-cooled condenser.
Both these conditions can cause an increase of condensing pressure, which leads to a reduction in energy efficiency and
refrigerating capacity.
Any side of the unit must be accessible for post installation maintenance operations and vertical air discharge must not be
obstructed. The Figure below shows the minimum space required.
