2.1. Climma DC chiller positioning

The Climma DC chiller must be installed in the engine room, technical space or similar area.
Normal engine room temperatures will not affect the Climma DC chiller, since the condenser and inverter
are water cooled. Climma DC chiller does not require additional ventilation during operation.
The unit must be accessible for service.
The unit must be secured on a surface using the mounting brackets below the drain pan.
WARNINGS
The Climma DC chiller is provided with an inverter mounted on the unit (VDF - Variable Frequency Drive) .
The inverter is IP20, therefore the Climma DC chiller must be installed where it would not get wet.

2.2. Electronic control box and display

The electronic control box of the Climma DC chiller is already completely connected to the chiller.
The control box has to be installed close enough to the chiller, due to the connection to the unit, and to a
flat horizontal or vertical surface.
The control box has to be installed in a location free from water, water spray and moisture and it has to
be accessible for operation and maintenance.
The standard version has the display on the control box itself, but the display can be also remote.
If the display is remote, the distance between the control box and the display has to be:

50 meters with standard cable

500 meters with AWG22 twisted pair cable. Note: please contact Veco if you plan to install the
display at a distance exceeding 50mt.

2.3. Flow switch installation

Flow switch has to be connected to the electronic control box and it needs to be installed in the fancoil
water circulation system.
Please refer to instruction C897 for the correct installation.
WARNING: Failure to properly install the flow switch will void the warranty on the Climma DC chiller.

2.4. Grounding

The Climma DC chiller has to be properly grounded to prevent corrosion due to stray current.
