•
The solidity of the support surface;
•
Avoid any obstacles to the flow of the fan which could cause the recirculation of air to the
condenser;
•
Avoid the possible reflection of sound waves: (do not install in narrow or tight spaces);
•
Provide access for maintenance or repair (see paragraph
3.3.1 Installation spaces
);
•
Average air temperature in the chosen installation area (see Section
7 Operating limits
).
Attention!
If the machine is installed outside, it could find itself at a temperature lower
than 0°C//32°F, when stopped; the formation of ice could damage the
evaporator. If you do not intend to drain the machine during the winter, you
must add
anti-freeze to the water circuit
(see paragraph
3.4.3 Use of
ethylene glycol as a winter anti-freeze
).
3.3.1 Installation spaces
To ensure the good functioning of the unit and access for maintenance, you must respect the minimum
installation space shown in the figure in this paragraph. The exit of air from the fan must not be
obstructed. In any case, avoid all situations in which hot air can circulate between the output of the
fan and the intake of the machine. Contact our office to verify feasibility in all cases where one of the
preceding conditions cannot be met.

ATER CONNECTIONS
Connect the machine to the water pipes following the instructions located near its water fittings (see
figures).
The installation of outlet and inlet taps on the machine is recommended, which will enable machine
maintenance without emptying the entire system, and emptying of the machine only during winter
downtime.
Important!
Install the mechanical water filter on its input: scum and impurities can
seriously damage the evaporator.
