2.3A Wiring the mains plug
As the colours
of the wires in the mains lead of this apparatus may not
correspond with the coloured markings identifying the terminals in your
plug, proceed as follows:-
1.
The wire
that is coloured green and yellow must be connected
to the terminal in the plug that is marked by the letter E, or by
the safety earth symbol coloured green, or green and yellow.
2.
The wire
coloured blue must be connected to the terminal that
is marked with the letter N, (Neutral connector)
3.
The wire
coloured brown must be connected to the terminal
that is marked with the letter L, (Live connector)
NOTE:
Replacement of the mains cable must be done by a competent
service engineer

Pneumatic requirements
The Beta Major and Minor
should be connected through a filter
regulator to a compressed air supply capable of delivering 60 cu.
litres/min at a pressure of 3.5-7 bar max.
(2 cu. ft./min at 50-101.5 psi.).
The press will not operate if the pressure drops below 3.5 bar
(40 Psi.)
.
Double hose clips should be used on the delivery hose.
2.5
Adjusting the pressure
This press is fitted
with a manually adjustable pneumatic pressure
regulator on the right hand side of the front of the base. To adjust the
operating air pressure, and therefore the pressure exerted by the press on
the work, the regulator is unlocked by pulling forward the black plastic
knob. Turning the regulator knob clockwise will increase the air
pressure; turning anticlockwise will decrease the pressure. When the
desired pressure is achieved the regulator is locked by pushing the knob
back in.
