Installation
Machine foundation
For making the foundation, check with a
professional engineer in order to calculate
the foundation regarding dynamic and static
forces.
The machines are designed to be bolted in
position to a concrete floor or specially prepared
concrete foundation. A template showing the size
of the foundation and positioning of the foundation
bolts is delivered with each machine.
For installation on an existing concrete floor, the
floor must be at least 8'' thick and of good quality.
If the floor does not meet these requirements, then
a 6-8'' high concrete foundation should be made.
Follow the instructions below when making a
concrete foundation:
1 Decide where to place the machine and
consider maintenance requirements, i.e.
determine a suitable distance from the rear of
the foundation to the wall, and the distance
from the foundation to the nearest side wall.
The distance should be at least 16 and 2
inches, respectively.
2. Break up the floor to a depth of at least
3 inches, making sure that the sides of the hole
slope inwards - the bottom of the hole should
be 5 inches longer than the upper length.
3. Wet the hole well. Brush the bottom and sides
with cement grout.
4. Prepare a casing and fill with concrete to form
foundation. Make sure the foundation is level.
5. Use the template to position the foundation
bolts correctly - bolts are to extend 1 1/2'' above
concrete.
Reinforcing ironrods A shall be used around the
base. The ironrods shall be placed between the
bolts and the edge of the foundation.

Electrical installation
Although the machines are fitted with a thermal
overload in the motor windings and a separate
fuse for the control circuit, a separate three-phase
common-trip circuit breaker must be installed for
all three-phase machines.
For proper overcurrent protection, check the data
plate at the rear of the machine. Also consult local
electrical code for special requirements.
The machine is equipped with a control circuit
transformer, mounted on the control unit and
connected for 220 volt operation.
If your incomming voltage is below 210 volts move
the wire connection to the 208 volt tab on the
transformer. If it is above 230 volts move the wire
to the 240 volt tab on the transformer.
Check the incoming power for a high voltage leg. If
present, connect that line to L2 on the terminal
block, a high voltage leg can be found by
measuring the voltage between each leg and
ground.
Connect L1, L2, L3 and ground wires according to
the markings of the terminal block. The cable is to
hang in a large loose loop, supported by the clip of
the terminal block.
The smaller terminal block at the right is for
connection of wires from external supply injection.
To ensure proper operation the drum must rotate
counter-clockwise (seen from the front) during
extraction. If the drum rotates in the wrong
direction the text ''PHASE-OR DOOR LOCK-
ERROR'' will be seen in the display window. If this
happens, interchange line L1 and L3 at the power
connection terminal.

NOTE
All plumbing must conform to national and
local plumbing codes.
Incoming water lines do not require non-return or
back-suction valves, as the machine is already
fitted with a siphon breaker. However, all incoming
lines must be fitted with shut-off valves.
• Water inlets are labelled for hot and cold water
connection.
• Flush the water system thoroughly and check
that the filter at the machine inlet is fitted
correctly.
• Connect the machine to the water mains with
3/4'' reinforced rubber hosing not to exceed 6 ft
in length. Hang the hosing in a large loop. Do
not use rigid piping.
Drain connection
Connect a 3'' (75 mm) flexible hose to the drain
outlet of the machine.
The drain hose must not have any sharp bends
and must slope from the machine to assure proper
drainage. The outlet must open freely to the main
drains.
Do not reduce the size of the drain connection
from the machine to the waste line.
