The connection of ducts for fresh and exhaust air to our devices is not suitable, as these units are
equipped with axial fans and these cannot build up the necessary additional air pressure.
To prevent performance losses, do not install the cooling unit near any form of heating.
Outdoor siting: Cooling units must be installed such that they cannot become damaged by internal
traffic and transport operations.

Installing the cooling unit
Install the cooling unit on an even, firm surface. The maximum permissible deviation from the verti-
cal is 2°. Avoid the production of noise due to vibration (vibration dampers, sheets of foam rubber)

The cooling medium outlet on the cooling unit (must be connected to the cooling medium inlet on
the equipment to be cooled. The cooling medium inlet on the cooling unit must be connected to the
cooling medium outlet on the equipment to be cooled.
Use only insulated pipes and/or hoses to connect the equipment to the cooling unit.
The nominal size of the piping must be at least the same as the nominal size of the medium connec-
tions on the unit, and on pressure-sealed units must be approved for the maximum pressure ex-
pected, see chapter 11.

For pressure-sealed units (nBoxX1.5)
Install a pressure manometer, 0 to 6 bar, in the cooling medium circuit.
Prior to commissioning, it is imperative that the cooling medium pump is filled with cooling medium
and bled, see chapter 6.

If the cooler on the equipment to be cooled is higher than the cooling unit, we recommend installing
a non-return valve in the feed as well as a solenoid valve in the cooling medium circuit return to pre-
vent the tank from overflowing.
