6. INSTALLATION
6.1 INSTALLATION CLEARANCES
It is important that an adequate air volume is available at the intake and exhaust sides of the condenser coil. It is
essential to avoid air recirculation between the intake and exhaust sides to prevent a reduction of the rated
performance levels and unit operating problems or a possible stop of normal unit operation. The minimum
clearances required for satisfactory operation of the unit is as follows (refer to figure 3):
- hydraulic connection sides: 1.5 metre.
- top: no impediments that obstruct the air discharge.
- electrical panel side: 1,8 meters (see dimensional drawings)
- hydraulic connection sides: 1.5 metre for pipe run location.
(*) It is recommended that sufficient space is allowed for plate heat exchanger withdrawal.
High walls near the machine may interfere with correct functioning. When units are side by side the minimum
distance between them should be 3 metres (see figure 3).

6.2 ANTI-VIBRATION ISOLATORS (option)
1.5 m
Figure 3
It is recommended that the unit is installed on rubber or spring anti-vibration mountings, supplied as an option, to
reduce vibrations transmitted to the building structure. It is advisable to use rubber isolators for units installed in
the basement, or ground floors in contact with the earth, and spring isolators for units installed on intermediate
floors.
6.2.1 Rubber Anti-Vibration Isolators
The anti-vibration isolators must be installed before the unit is
positioned. Ensure that during lifting the unit is firmly secured with
straps.
Rubber isolators are made of an upper metallic bell with a fixing screw to the base-frame of the unit. The isolator
is fixed at the foundation via 2 holes on the flange. On the flange there is a number (45, 60, 70 ShA) which
identifies the hardness of the rubber isolator. The dimensional drawing, enclosed in the machine, shows the unit
footprint with the position and weight of each isolator.
