MECHANICAL INSTALLATION
3.1
Safety
The unit must be firmly secured to the soil.
It is essential to observe the following instructions:
−
The unit can only be lifted using the lifting points marked in yellow fixed to its base.
−
It is forbidden to access the electrical components without having opened the unit main switch and switched off the
power supply.
−
It is forbidden to access the electrical components without using an insulating platform. Do not access the electrical
components if water and/or moisture are present.
−
Sharp edges and the surface of the condenser section could cause injury. Avoid direct contact and use adeguate
protection device
−
Switch off power supply, by opening the main switch, before servicing the cooling fans and/or compressors. Failure to
observe this rule could result in serious personal injury.
−
Do not introduce solid objects into the water pipes while the unit is connected to the system.
−
A mechanical filter must be installed on the water pipe connected to the heat exchanger inlet.
−
The unit is supplied with safety valves, that are installed both on the high-pressure and on the low-pressure sides of
the refrigerant circuit.
It is absolutely forbidden to remove all protections of moving parts.
In case of sudden stop of the unit, follow the instructions on the
Control Panel Operating Manual
which is part of the on-
board documentation delivered to the end user.
It is strongly recommended to perform installation and maintenance with other people. In case of accidental injury or
unease, it is necessary to:
-
keep calm
-
press the alarm button if present in the installation site
-
contact immediately emergency rescue personnel of the building or the Health Emergency Service
-
wait without leaving the injured person alone until the rescue operators come
-
give all necessary information to the rescue operators
-
Avoid installing the unit in areas that could be dangerous during maintenance operations, such as platforms
without parapets or railings or areas not complying with the clearance requirements around the unit.
1.1
Noise
The unit is a source of noise mainly due to rotation of compressors and fans.
The noise level for each model size is listed in sales documentation.
If the unit is correctly installed, operated and manteined the noise emission level do not require any special protection
device to operate continuosly close to the unit without any risk.
In case of installation with special noise requirements it could be necessary to install additional sound attenuation devices.
3.2
Moving and lifting
Avoid bumping and/or jolting during loading/unloading unit from the truck and moving it. Do not push or pull the unit from
any part other than the base frame. Secure the unit inside the truck to prevent it from moving and causing damages. Do
not allow any part of the unit to fall during transportation or loading/unloading.
All units of the series are supplied with lifting points marked in yellow. Only these points may be used for lifting the unit, as
shown in the following figure.
Use spacing bars to prevent damage to the condensation bank. Position these above the fan grills at a distance of at least
2.5 metres.
The equipment, ropes, lifting accessories and handling procedures must comply with local regulations and current
regulations.
Use only lifting hooks with locking device. The hooks must be securely fixed before handling.
The lifting ropes, hooks and spacing bars must be strong enough to support the unit safely. Please check the unit weight
on the unit nameplate.
The installer has the responsibility to ensure the selection and correct use of the lifting equipment. However, it is advisable
to use ropes with a minimum vertical capacity equal to the total weight of the machine.
The machine must be lifted with the utmost attention and care following lifting label instructions; lift the unit very slowly,
keeping it perfectly level.
3.3
Positioning and assembly
All units are designed for installation outdoors, either on balconies or on the ground, provided that the installation area is
free of obstacles that could reduce air flow to the condensers coil.
The unit must be installed on a robust and perfectly level foundation; should the unit be installed on balconies or roofs, it
might be necessary to use weight distribution beams.
