Identification Labels On The Ultracool Unit; Water Connection - Lauda ULTRACOOL UC 8 Manual

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")
the UC 50 and 65 models
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 3.1).
The Ultracool units must always operate with the panels closed to enable the inlet of fresh air only
through the condenser.

2.5 WATER CONNECTION

Leave at least 1.5 meters (5 feet) of flexible pipe right after the chiller's inlet and outlet connection. This will
allow moving the chiller for a better maintenance access without dismantling the water pipes.
The chiller should be located as close as possible to the application. Pressure drop in the pipe should not
exceed 0.7 bar. The water lines must be in pipes of at least 1" for UC 8 to 24 models and 1 ½" for UC 50
and 65 models.
Minimize the number of bends in the water lines. The length of hose, number of fittings, valves, etc. will also
cause an increase of the pressure drop.
Always install thermal insulation for all pipes or, at least, make sure that the pipes are opaque to the light.
