Warning:
Q Both the lifting ropes and the spacing bar and/or scales must be sized to support the machine
weight safely. Please check the unit's weight on the machine's nameplate. The weights shown in
the 'Technical data' tables in the 'General information' chapter refer to standard units, without any
added accessories. The specific machine may have accessories that increase its overall weight
(pumps, copper banks/copper, etc.).
Q The machine must be lifted with the utmost attention and care. Avoid jolting when lifting and lift the
machine very slowly, keeping it perfectly level.
Q If the machine is fitted with soundproof cabins for the compressors, remove the side panels at the
lifting points to avoid damage and deformation.
Positioning and
assembly
All units are designed for installation outdoors on terraces or the ground, as long as the area is free
from obstacles that could limit air flow to the condensation banks. The machine must be installed on
a robust and perfectly level foundation. Should the machine be installed on balconies and/or roofs, it
may be necessary to use weight distribution beams. For installation on the ground, there must be a
robust cement base that is at least 250 mm longer and wider than the machine. Furthermore, this base
must be strong enough to support the weight of the machine as stated in the technical specifications.
Should the machine be installed in places that are easily accessible to people and animals, it is
advisable to install protection gratings for the banks and compressors, and guarantee access to the
machine only when in a safe condition. To ensure the best possible performance on the installation
site, the following precautions and instructions must be followed:
Q Avoid recirculation of air flow out from the fans towards bank suction.
Q Ensure there are no obstacles obstructing air flow to the banks, guaranteeing correct suction and
expulsion.
Q Guarantee a strong, solid foundation to reduce noise and vibration as much as possible.
Q Do not install in particularly dusty environments as this will dirty the condensation banks.
Q The water in the system must be particularly clean and all traces of oil or rust must be removed. A
mechanical water filter must be installed on the machine's inlet piping.
Clearance Correct machine operation depends on compliance with the minimum clearance requirement for
installation, which guarantee correct ventilation of the condensation banks. Reduced installation space
could reduce normal air flow, significantly reducing machine performance and increasing the electricity
consumed. In determining the correct machine position, consider the following factors:
Q Avoid any recirculation of hot air between fans and condensers.
Q Avoid under-supplying the air flow to the condensation banks.
Both these conditions can cause the condensation pressure to increase, determining a reduction in
energy efficiency and refrigeration capacity (despite the fact that the unit's condenser geometry allows
it to partly compensate for poor air distribution, and software is particularly able to calculate machine
operating conditions and optimise load in abnormal operating conditions). Machine installation not only
guarantees its correct operation, but also allows for all post-installation and maintenance work to be
carried out correctly. The figure below shows the minimum clearance requirements. If the machine is
positioned in a place surrounded by walls or obstacles of the same height as the machine, it must be
at least 2500 mm away from these. Should the obstacles be higher, the machine must be at least
3,000 mm away from these. If the machine is installed without complying with these recommended
minimum distances from walls and/or vertical obstacles, hot air may re-circulate and/or the air
condenser may be under-supplied and this can lead to a loss of efficiency.
