Unpacking
Carefully remove any packaging to avoid damaging the machine. Different packaging materials are used: wood, cardboard, nylon etc.
Keep them separate and dispose of them at appropriate waste disposal or recycling facilities in order to minimise the environmental
impact.
Once the machine is positioned, loosen the bolts to remove the pallet. Then push the unit from below and slide it to its proper position.
Siting
Bear in mind the following when choosing the best site for installing the unit and the connections:
- Size and origin of water pipes;
- Location of power supply;
- Access for maintenance or repairs;
- Stability of the supporting surface.
All the models of the AQUA
4
series have been designed and built for outdoor installations. Since soundproofing and protections of
components and hot parts are specially designed, the AQUA
4
series models do not need to be kept inside.
It is advisable to place a vibration damping system between the base frame and the supporting surface.
Installation clearance requirements
It is important to provide an adequate volume of air on the intake and delivery sides of the condensing/evaporating finned coils. It is
essential to prevent air recirculation between intake and delivery, as this may affect unit performance or interrupt normal operation. For
this reason provide the following clearances (see figure on this page):
- hydraulic connections/back side: at least 1 meter to provide room for water connections and/or maintenance to the flow switch
expansion vessel tank pump unit.
- electric panel side: at least 1 meter to guarantee access for inspections and/or for maintenance of cooling components
- finned-pack condenser side: at least 1.5 meters to ensure proper air circulation as well as access (even from the side) to the
compressor compartment
- upper side: during expulsion there must be no obstacles.

12.3 Water connections
When setting up the water circuits for the evaporator follow the instructions below and comply with national or local standards (use the
diagrams attached to this document as reference).
Fit the piping to the cooler with flexible joints to dampen vibrations and to
compensate for thermal expansion. Refer to the technical data table for the type and dimensions of the hydraulic connections.
It is recommended to install the following components on the piping:
1.0 m
back
1.0 m
front
1.5 m
1.5 m
When installing the unit, for safety purposes, make sure that the room temperature does not exceed 50°C
(with unit on or off).
Should refrigerant leak in the vicinity of open flames or in a room without sufficient ventilation, it could catch
fire and the combustion by products could be harmful to people.
