WARNING: Failure to properly ground the Climma DC chiller will void warranty.
2.5. Chiller condensate
Every Climma DC chiller has two drains for condensate water.
At least one drain has to be properly connected to ensure the correct condensate water drainage.
Plastic condensate drain nipples are provided in a separate plastic bag to help the installation.
2.6. Other system components: fancoils
Climma fancoils have to be installed in a technical space inside or close to the cabin they have to
cool/heat.
Fancoils need to be properly secured on a leveled surface in order to operate correctly and remove the
condensation. Return air flow from the fancoil has to be ensured as well as the supply air flow from the
fancoil.
WARNING
No fancoil has to be installed close to engine room area and it must be ensured that no vapor or air from
the engine room can enter in the return air flow of the fancoil.
The positioning of the fancoil display is important. The temperature sensor is mounted on the display,
therefore the display has to be mounted on an inside wall, around the mid-height of the cabin where the
air can circulate so that it can sense the correct temperature.
If a correct positioning is not possible, a remote temperature sensor can be mounted; in this case, the
sensor must be placed behind the return air grill. In this case, the display temperature sensor will be
automatically excluded.
WARNING
Do not place the temperature sensor on the supply air flow or close to return/supply grills, under the
sunlight or close to heating devices.
Ducting of the return and supply air of the fancoil has to be done properly; ducts must be short and as
straight as possible, avoiding bends greater than 90° or loops.
Supply air ducting has to be at least 1.5 meter (5') in order to reduce fan motor noise, but it should not
exceed 6 meters in order to reduce pressure drops.
Supply and return grills must be located not too close to each other, in order to avoid the supply air to
enter directly in the return air flow. Return grill should be placed below while supply grill should be
placed over the mid-height, as high as possible in the cabin.
WARNING
Failure to proper position the supply and return grills will cause no mixing between the cooler
temperatures and the warmer temperatures.
All Climma fancoils are provided with condensate drains to remove condensation produced by the
fancoil; condensation can reach 2 liters per hour, therefore condensate drains must be properly
connected and tested during installation. Drains should be as short and as downhill as possible, with no
loops and bends.
To test it, pour some water in the fancoil pan and check that all water flows out of the pan through the
drains.
2.7. Other system components: sea water circuit
The Climma DC chillers have a water cooled condenser therefore they need to be connected to sea water
to operate correctly.
