Cooling Water Connection; Connection Of Process Gas And Cda; Figure 5: Rear Side Of External Switchbox - UniTemp RSS Series Operation Instructions Manual

The power supply socket (see no.
17 in Figure 5) has to be
connected to local single phase
power supply socket (100...230V).
The chiller has to be connected to
chiller power supply socket (see
no. 18 in Figure 5).
The status LED shows a green
light when the chiller is switched on
by reflow solder system.

2.2 Cooling water connection

The cooling water connections are placed at the rear side of the system. The cooling
water inlet is done using plastic tube with outer Ø 8 mm (8 x 6 x 1) (see no. 10 in Figure
2), the cooling water outlet using plastic tube with outer 10 mm (10 x 7.5 x 1.25) (see no.
9 in Figure 2).
 Maximum inlet pressure: 5 bar
 ΔP Input - Output:
 Water temperature:
Only decalcified water should be used. Optionally we offer a closed loop water cooling
system; the cooling water will be enriched with a commercial available standard cooling
water addition. For a limited period an operation with mains water is admissible.
Important - Attention:
Connection to tap water is at your own risk; there is no warranty for clogged cooling
channels.

2.3 Connection of process gas and CDA

The RSS-110-S reflow solder system features two different types of gas inlet
connections (see Figure 2 and Figure 3):
i) Process gas inlet: there is one inlet (PU tube with outer diameter 4 mm)
located at rear side of chassis (see no. 14 in Figure 3). The maximum flow of
nitrogen (N
MPa) is required.
ii) CDA (compressed dry air): there is one inlet (PU tube with outer diameter 6
mm) located at left bottom side of connector block. Compressed dry air
(cleaned, dry and oil-free compressed air) is required to drive the heating
plate (pneumatic operation) and the vacuum valve (if vacuum option is
ordered). As alternative inert gas (e.g. nitrogen gas) can be used. A pressure
of 3.5...4 bar (0.35...0.4 MPa) is required.
