3 Positioning
During positioning consider these elements:
•
Technical spaces requested by the unit
•
Electrical connections
•
Water connections
•
Spaces for air exhaust and intake
3.1 Functional
spaces
Functional spaces are designed to:
•
guarantee good unit operation
•
carry out maintenance operations
•
protect authorized operators and exposed people
Respect all functional spaces indicated in the DIMENSIONS section.
Double all functional spaces if two or more unit are aligned.
3.2 Positioning
Units are designed to be installed:
•
EXTERNAL
•
in fixed positions
Limit vibration transmission:
•
use antivibration devices on unit bearing points
•
install flexible joints on the hydraulic connections
Choose the installation place according to the following criteria:
•
Customer approval
•
safe accessible position
•
technical spaces requested by the unit
•
spaces for the air intake/exhaust
•
max. distance allowed by the electrical connections
•
avoid flood-prone places
•
verify unit weight and bearing point capacity
•
verify that all bearing points are aligned and leveled
•
install the unit raised from the ground
•
consider the maximum possible snow level
A correct circulation of the air is mandatory to guarantee the good unit operating.
Protect the unit with suitable fence in order to avoid access to unauthorised personnel (children, vandals, etc.)
Avoid therefore:
•
obstacles to the airflow
•
difficulty of exchange
•
leaves or other foreign bodies that can obstruct the air coil
•
winds that hinder or favour the airflow
•
heat or pollution sources close to the unit (chimneys, extractors etc..)
•
stratification (cold air that stagnates at the bottom)
•
recirculation (expelled air that is sucked in again)
•
incorrect positioning, close to very high walls, attics or in angles that could give rise to stratification or recirculation phenomenons
Ignoring the previous indications could:
•
reduce energy efficiency
•
alarm lockout due to HIGH PRESSURE (in summer) or LOW PRESSURE (in winter)
3.3 Saftey valve gas side
The installer is responsible for evaluating the opportunity of installing drain tubes, in conformity with the local regulations in force (EN 378).
