Detach TegraPol from the bottom of the packing case by removing
the four screws from below.
Place TegraPol on a steady table with an adequate working height.
The machine must be close to the power supply, water mains and
water outlet facilities.
Water for wet grinding may be supplied from the water mains or a
Recirculation Cooling Unit (instructions on the next page).
IMPORTANT
The cold water supply must have a head pressure in the
range 1 – 10 bar (14.5 – 145 psi).
Mount the 90° end of the inlet hose onto the water inlet tube on
the back of TegraPol (see Getting Acquainted with TegraPol):
Insert the filter gasket in the coupling nut with the flat side
against the pressure hose.
Tighten the coupling nut completely.
Mount the straight end of the inlet hose on the water mains tap
for cold water:
Mount the reduction ring with gasket on the water mains tap,
if necessary.
Introduce the gasket and tighten the coupling nut
completely.
Mount the outlet hose onto the water outlet tube (Lubricate with
grease or soap to facilitate insertion). Use a hose clamp for
fastening.
If there is only limited space behind the TegraPol, use the pipe
bend and attach it directly to the outlet tube on the back of the
TegraPol. Then attach the drain hose to the other end of this
bend.
Lead the other end of the drain hose to the water outlet. Arrange
the tube so that it slopes downward towards the drain throughout
its length. Shorten the hose, if necessary.
REMEMBER
Make sure that the drain hose slopes downward towards the drain
throughout its length and avoid sharp bends in the drain hose.

To ensure optimal cooling, TegraPol can be fitted with a Struers
Recirculation Cooling Unit.
Please note:
The Recirculation Cooling Unit cannot be used with TegraPol units running
methods that include the dosing of oxide polishing suspensions.
Note
Before connecting the cooling unit to the TegraPol,
follow the instructions in the Struers Cooling Units Instruction Manual
to prepare it for use.
Take the inlet hose delivered with TegraPol and cut off the
coupling nut on the straight end.
Slide the hose clamp onto the hose and insert the quick coupling
delivered with the pump for the recirculation cooling unit. Tighten
the hose clamp.
Connect the quick coupling on the inlet hose directly to the cooling
unit’s pump outlet (A).
If necessary, use one of the hoses delivered with the pump to
extend the inlet hose.
Mount the other end to the water inlet tube.
Mount the outlet hose onto the water outlet tube. Use a hose
clamp to secure the hose.
If there is only limited space behind the TegraPol, use the pipe
bend and attach it directly to the outlet tube on the back of the
TegraPol. Then attach the drain hose to the other end of this
bend.
Lead the other end into the mounting hole in the bracket on top of
the static filter unit (B). Arrange the tube so that it slopes
downward towards the drain throughout its length. Shorten the
hose, if necessary.
Connect the communication cable to the Cooli Control Box and
then connect to the socket 1 at the rear of the TegraPol.
IMPORTANT
Before connecting, check that the mains voltage corresponds to the voltage
stated on the type plate on the side of the machine.

The TegraPol is shipped with 2 types of Mains cables:
The 2-pin (European Schuko) plug is for use on single-phase
connections.
If the plug supplied on this cable is not approved in your country,
then the plug must be replaced with an approved plug. The leads
must be connected as follows:
Yellow/green: earth
Brown: line (live)
Blue: neutral
The 3-pin (North American NEMA) plug is for use on 2-phase power
connections.
If the plug supplied on this cable is not approved in your country,
then the plug must be replaced with an approved plug. The leads
must be connected as follows:
Green: earth
Black: line (live)
White: line (live)
Both cables are on the other end equipped with an IEC 320 cable
connector that has to be connected to the TegraPol.
WARNING!
The output voltage from this cable is 200 – 240V and not 110V.
DO NOT use this cable to connect equipment that use an 110V power
supply. Failure to adhere to this may result in material damage.

Lead the supporting column of TegraForce-1 down into the hole
at the back of the TegraPol.
Then both the distance between disc and specimen mover plate
and the position of the specimen mover plate over the disc have
to be adjusted.
To adjust the correct distance mount a preparation disc on
TegraPol and a specimen mover disc on the TegraForce-1.
Loosen the 2 fastening screws and adjust the space between the
disc and specimen mover plate to about 1 -1.5 mm.
Re-tighten the 2 fastening screws again.

Electrical Connections
Compressed Air Connections
Emptying the Water / Oil Filter
There is a single electrical connection between the TegraPol and the
TegraForce. This provides both the 24V power supply to the
TegraForce and a data bus, which enables the TegraPol and
TegraForce to communicate.
Switch off the TegraPol.
Use the single cable attached to the TegraForce, and connect it
to the Sample Mover connector on the rear of the TegraPol. To
locate this connector, refer to the diagram for the back of the
TegraPol in the section "Getting Acquainted with TegraPol".
The quality of the air in the compressed air system used with this
machine must meet the standards stated in ISO 8573-1. To connect
the TegraSystem:
Mount the quick coupling on the pressure hose and secure it with
the hose clamp supplied.
Connect the air hose to the quick coupling and fit the other end
into the compressed air inlet on TegraForce-1.
IMPORTANT
The air pressure must be between 5 bar (72 psi) and 10 bar (145 psi) and
have a quality specified in ISO 8573-1.
TegraForce is fitted with a water / oil filter that removes excessive
amounts of these substances from the compressed air supply. As a
result of this, it is necessary to empty the filter periodically:
Remove the preparation disc from the work area. Failure to do
this may result in the preparation disc being contaminated by
water and oil particles landing on it.
Locate the release outlet valve on the bottom of the filter glass.
Release Outlet Valve
Hold a container under the filter to retain any water released and
press the release valve.
Replace the preparation disc.

Remove the TegraDoser-1 or the dosing nozzle from
TegraDoser-5 from the TegraForce.
Disconnect the TegraForce from the TegraPol by removing the
plug.
Release the handle and let the TegraForce swing in the upper
position.
Remove the preparation disc.
Press the TegraForce down again until the head is locked in
position.
Remove the two caps covering the fastening screws on the left-
hand side of the TegraPol cabinet by lifting them off with a knife.
Loosen the two fastening screws while holding the TegraForce in
position.
WARNING!
TegraForce is relatively heavy. When loosening the two fastening screws it
might slide downwards. Keep your hands off the column and away from
between specimen mover disc and turntable.
Lift the TegraForce straight up and place it on a safe and stable

WARNING!
When working with specimen holders make sure that the screws clamping
the specimens do not stick out of the specimen holder.
Use different length of screws for samples with different diameters.
When a TegraPol, which has been fitted with a TegraForce-1, is
switched on, the software inside the TegraPol is able to detect the
TegraForce-1, automatically, and informs you of its presence in the
