3.1 Operation Conditions
The control thermostat in the chiller will control it in order to maintain the
preset cold water temperature.
Water temperature at the inlet:
Nominal:
15ºC (60ºF)
Maximum:
30ºC (86ºF)
Cold water temperature at the outlet:
Nominal:
10ºC (50ºF)
Minimum:
5ºC (40ºF) (1)
Maximum:
15ºC (60ºF)
(1) To reach this temperature it is necessary to add a 10% ethylene
glycol to the water and contact an authorised technical service to adjust
the chiller.
Temperature of the ambient air:
Nominal:
25ºC (77ºF)
Minimum:
-15ºC (5ºF) (2)
Maximum:
50ºC (122ºF)
(1) For ambient temperatures below 5ºC (40ºF) it is necessary to add
ethylene glycol to the water of the circuit (see point 2.4).
3.2 Before start-up of the ultracool unit
Clean the application water circuit with tap water in order to be sure that
there are no free particles. Otherwise the filter elements can block up
during the start up process.
The following points must be checked:
-
Lateral panels closed.
-
Filling of the water circuit of the ultracool unit (see point 4.3).
-
Water connections.
-
Connection valves to the water line are open.
-
External circuit protection is connected.
