Water for wet grinding may be supplied from the water mains or a
Recirculation Cooling Unit (instructions on the next page).
Mount the 90° end of the inlet hose onto the water inlet on the
back of Tegramin (see Getting Acquainted with Tegramin):
−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:
−If required, mount the reduction piece with gasket on the
water mains tap and tighten the coupling nut completely.
Mount the outlet hose onto the water outlet pipe. (Lubricate with
grease or soap to facilitate insertion.) Use a hose clamp for
fastening.
Lead the other end of the drain hose to the water outlet. Arrange
the hose so that it slopes downward towards the drain
throughout its length. Shorten the hose, if necessary.
Supplying Water
Connection to Water Mains
IMPORTANT
The cold water supply must have a head pressure in the
range 1 – 10 bar (14.5 – 145 psi).
Connection to Water Outlet
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, Tegramin can be fitted with a Struers
Recirculation Cooling Unit.
Take the hose delivered with the pump and remove the quick
coupling from one end.
Slide the hose clamp onto the hose and connect to the back of the
Tegramin. Tighten the hose clamp.
Connect the quick coupling on the other side of the inlet hose
directly to the cooling unit’s pump outlet (A).
Mount the water outlet hose onto the water outlet pipe. Use a
hose clamp to secure the hose.
Lead the other end into the mounting hole in the bracket on top of
the static filter unit (B).
Arrange the hose so that it slopes downward towards the drain
throughout its length. Shorten the hose, if necessary.
Connecting a Recirculation
Cooling Unit
Oxide Polishing:
A Shift Valve is REQUIRED when using a Recirculation Cooling Unit
with Tegramin units running methods that include the dosing of
oxide polishing suspensions -OP.
Note
Before connecting the cooling unit to the Tegramin,
follow the instructions in the Struers Cooling Units Instruction Manual
to prepare it for use.

Connect the communication cable to the Cooli Control Box and
then connect to the socket at the rear of the Tegramin.
With the outlet hose mounted onto Tegramin's water outlet pipe,
mount the other end of the hose onto the pipe labelled From
Tegraminon the shift valve.
Mount a 1.5 m piece of hose onto the pipe marked Cooli and
lead the other end to the recirculation cooling unit. Use a hose
clamp for fastening.
Mount the second 1.5 m piece of hose onto the pipe marked
Drain and lead the other end to the drain. Use a hose clamp for
fastening.
Connect the blue compressed air hose to the air outlet on
Tegramin and fit the other end to the shift valve, marked Connect
to Tegramin.
Connect the plug to the socket at the back of the Tegramin
marked Shift valve.
Connecting the Communication
Cable
IMPORTANT
Before connecting to power, check that the mains voltage corresponds to
the voltage stated on the type plate on the side of the machine.
Installing the Shift Valve
(Accessory)
IMPORTANT
When connecting Tegramin to both mains water AND the recirculation
cooling unit you also must install the shift valve for the drain.
Failure to do this may result in emptying or overflowing
the recirculation cooling unit.
Note:
The Shift Valve for Tegramin set includes some extra pieces
not used for Tegramin-25/-30
(1 short piece of hose, 1 reduction piece and 2 hose clamps)
REMEMBER
Make sure that the hoses slope downward throughout their length, from
Tegramin to the shift valve and from shift valve to Cooli (or drain).
Avoid sharp bends in the hoses. Shorten the hoses, if necessary.

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 compressed air:
Mount the quick coupling on the compressed air hose and
secure it with the hose clamp supplied.
Connect the air inlet hose to the quick coupling and fit the other
end into the compressed air inlet on Tegramin.
Tegramin 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:
Locate the release outlet valve at the back of the machine.
Hold a cloth under the filter to retain any water released and
press the release valve.
An exhaust system should be connected when using alcohol based
suspensions or lubricants.
Connect a 50 mm pipe to the outlet at the rear of the machine,
on the left and connect to the exhaust system.
Recommended capacity for exhaust system: 180m3
/h at 0mm water
gauge.
Compressed Air Connections
IMPORTANT
The air pressure must be between 6 bar (87 psi) and 10 bar (145 psi) and
have a quality equal to or better than Class-3, as specified in ISO 8573-1.
Note:
Tegramin requires a continuous flow of compressed air
through the regulator valve –
a faint hissing sound does not mean that there is an air leak.

Always remember to switch the power off when installing electrical
equipment.
The Tegramin 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 (ground)
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 Tegramin.
