ASSEMBLY (CONNECTIONS)
CONNECTION TO THE REFRIGERANT CIRCUIT (CONSUMER CIRCUIT)
All work may only be carried out by specialist personnel!
Procedure:
In closed systems, make sure that the maximum obtainable cooling medium pressure in the supply
-
line does not cause a higher pressure level than the maximum permitted for the chiller.
Check the cleanliness of the supply line and the piping system to be connected.
-
Connect the chiller with the consumer circuit; the identification of the joints (cooling medium in-
-
let/outlet) is indicated on the chiller by means of the symbols described in the introduction to the
manual.
Make all the connections, without rotating the sleeves located on the hose.
-
The cooling medium circuits of the Series CHW and CHG with tank are open to the atmosphere
as standard!
Use piping, connections and fastening components with a cross-section to match the capacity of the
chiller and the possible volume flow. This should not be smaller than the diameter of the chiller connec-
tions.
In the case of rigid connections, check during the initial start-up of the chiller that it is not subject to any
vibrations that might endanger the integrity of the components.
We also recommend that you should plan to install the following system components:
A bypass system with suitable valves upstream and downstream of the chiller. This is intended to allow use of
♦
the consumer circuit if you have to remove the chiller from the circuit, switch it off or use it in different ways
at the same time.
A pipeline system with integrated filter near the chiller to protect the pump against solid matter and avoid de-
♦
posits on the heat exchangers. The recommended mesh width for the chillers is 25µ with a maximum pres-
sure loss at the filter of 1 bar. The use of a filter with a mesh width of 60µ is particularly suitable for chillers
of the CHO series if they are fitted with a gear pump, so as to avoid unusual wear of the component.
In the models without flow monitoring, we suggest that you should install such a component if the system ex-
♦
hibits losses or very high cooling medium consumption due to evaporation or intervention by the operator. A
