Models UC 2 and UC 4 have an electrical protection degree of IP32. If installed outdoors, they must be
completely protected from rain and installed in such a way that the control panel receives as few direct
sunlight as possible. For both models an option “Outdoor installation” is available that ensures an electrical
protection degree of IP54.
Models UC 8 to UC 100 have an electrical protection degree of IP54. In the case of outdoor installation, it
is recommended to protect the Ultracool unit from rain with a roof.
Leave a space of 0,5m (20”) around the chiller for UC 2 and UC 4 models, 1m (40”) for UC 8 to UC 24
models and 2m (80”) for the UC 50 to UC 100 models. This space is important to facilitate maintenance
work and cleaning, especially in front of the condenser (the heat exchanger on the back side of UC 2 and UC
4 models, the left side of UC 8 to UC 65 models and both left and right sides of UC 80 and UC 100).
If necessary, units UC 8 to UC 65 can be installed without any free space on the right and back sides. In this
case, foresee that the unit can be moved forwards to free the access panels when there are maintenance
works to be carried out.
The inlet of fresh air onto the condenser should be in the most direct way possible, avoiding any chance of air
recycling (the ceiling above should not be at less than 1m (40”) for UC 8 to UC 24 models and 2m (80”)
for the UC 50 to UC 100 models.
UC 2 and UC 4 models do not need any free space above them during operation, but at least 0,5m (20”)
should be available to have enough space to remove the top panel and access the electrical box inside. If no
space is left available on top of the unit, foresee that it can be moved forwards to free access to the top panel.
In case of installation in a small room it is imperative that the room has an appropriate ventilation system to
evacuate all the heat generated by the chiller as explained before on this same point. If the heat is not
removed the temperature in the room will quickly increase beyond the operating limits of the unit and it will
stop by high pressure alarm (see point 4.1).
The Ultracool units must always operate with the panels closed to enable the inlet of fresh air only through
the condenser. The only exception to this are models UC 2 and UC 4, which can still work even if the lateral
panels are open.
