Connecting Unit To Drain (Water Cooled Models)
•Drain must be located at least 150mm. below machine level. Drain tube must have an inner diameter of
30mm. with a minimum gradient of 3 cm per metre.
Electrical connection
• Unit is provided with a 1.5 m cord and Schucko socket.
• It is recommended to install a switch and adequate fuses. Nominal voltage and intensity are indicated on
rating plate as well as on this manual's technical pages. Voltage fluctuations greater than 10% can cause
problems or prevent machine from starting.
• Line to base of plug must have a minimum section=2.5 mm2.
• Ensure voltage indicated on rating plate corresponds to that of mains supply.
Machine levelling
Place machine where it is required, and level the machine ONCE all four legs have been screwed on
Space requirements
There should be a 150 mm gap on sides and top of the machine so as to allow air to circulate and prevent
heat build-up.
Float (buoy) valve level
This valve is factory set, but may need to be adjusted if mains water pressure is very high or very low. To do
so, loosen the two small screws which connect the micro-switch to the steel support. Move micro-switch as
required and tighten screws. Water level must be about 5mm below the evaporator coil to, otherwise there
may be difficulty in releasing cubes in winter.
Note that if mains pressure is subject to large fluctuations, it will be difficult to maintain a constant water
level, in this case it may be advisable to install a pressure regulator on the water mains line.
