7 DRAIN CONNECTION (K-Kwts-S-M-C-B)
The machine has a rubber connecting pipe with pipe-end fi tting, approx. 1.5 metres in length.
This pipe must be made to fl ow into a fi xed drain manifold with a minimum internal diameter
of 35 mm located underneath the machine work counter.
The space created by difference in diameter of the two pipes inserted one into the other
must be left free for the venting of air during the discharging of the water.
1) Hook up the rubber pipe from the metal pipe or from the plastic drain box installed
in the machine to the drain manifold located underneath the counter, ensuring that
it does not sag and that it is not strangled.
8 ELECTRICAL CONNECTIONS (K-Kwts-S-M-C-B)
The machine is equipped with a connecting power cable, approx. 2 metres in length,
with 5 wires of the following colours:
- Green/Yellow:
- Blue:
- Brown:
- Black:
- Grey:
The wires should, preferably, be connected to a terminal board on the electric switchbo-
ard; if a plug is to be used, it should be an industrial plug with a suffi cient capacity to power
the machine.
The connection may be made without any modifi cation being required to the machine,
either to a single-phase 230VAC power supply or to a triple phase 400VAC N3 power supply,
as follows:
8.1
SINGLE-PHASE 230VAC CONNECTION
Hook up the Ground and Neutral wires to the two respective terminals on the electric switch-
board.
Join up the three wires of phases 1, 2 and 3 themshelves and connect them to the single
terminal of the phase present in the electric switchboard.
8.2 THREE-PHASE 400VAC N3 CONNECTION
Hook up the Ground and Neutral wires to the two respective terminals on the electric switch-
board.
Connect each of the three wires of phases 1, 2 and 3 to the respective terminals
of the phases present in the electric switchboard.
The wiring diagram and electrical data are shown on the two plates located underneath
the drip tray (K-Kwts-S-M-C) or inside the upper cup tray (B).
