• Protection index of the unit:
- IP 44 : for the electrical equipment,
(IPXXB : for the mechanical hazards).
• Before installation, verify the following points:
- the unit must be installed outside in an appropriate location and in compliance with environmental requirements (sound
level, integration, etc...),
- the water chiller’s installation location must be perfectly level and strong enough to support the weight of the unit and must
have adequate inundation protection,
- sufficient space around the unit should be provided in order to facilitate servicing and maintenance operations,
- air suction to the coil and fan discharge must not be obstructed,
- install the unit above the region’s average snowfall level.
- vibrations and noise must not be transmitted to adjacent buildings,
- install the machine on anti-vibration pads and fit hoses on piping elements, as required,
- if necessary, consult an acoustics specialist concerning the unit’s optimum location,
-4 holes Ø 22.5 enable to place hoisting hooks and lift the unit.
11.2 - ELECTRICAL CONNECTIONS
• All required information is indicated on the electrical diagram provided with the unit and in the installation manual.

If a freeze risk is present, one must:
- either drain the installation,
- or inject glycol into the system.
- With the anti-freeze resistance option
The electrical power supply must be separate from
the generator power supply (if power the generator
is cut, the unit would no longer be protected from
freezing). External installation pipework must be
protected.
