4.1 Fluid connections
For the hoses of the heating medium circuit and cooling water the following minimum internal diameters
and hose qualities are recommended:
heating medium R 1/2“ female thread
internal hose diameter 13 mm
cooling water R 3/8“ male thread
internal hose diameter 10 mm
water filter at the cooling water inlet R 3/8“ female thread
The use of pressure and temperature resistant hoses is recommended for safety (pressure resistant up to
min. 10 bar). It is important to use hoses which are resistant to heat transfer liquids.
MARK AND TAKE DOWN THE MAXIMUM TEMPERATURE
FOR WHICH THE CONNECTIONS ARE SUITABLE.
Quick release couplings will give reduced flow.
If the recommended tube size cannot be connected to the mould, the connection at the mould should be
reduced and not the connection on the temperature control unit. In this way pressure drops can be avoided.
4.2 Power supply
Mains voltage and frequency according to the serial plate.
Pay attention to the local regulations during the installation of the unit.
CAUTION!
THE CONNECTION TO THE POWER SUPPLY HAS
TO BE DONE BY A COMPETENT ELECTRICIAN.

Manual TT-180 - 6 -
4.3 Filling
filling amount: approx. 6 litres
Automatic filling (only for water operation):
- The unit has to be connected hydraulically and electrically.
- The ball valve (behind the solenoid valve) of the automatic filling has to be open (see chapter 15).
- Switch the unit on.
- After switching on the unit the tank will be filled with water via the cooling connection to the correct level.
- Only when the system has reached the minimum level, the pump will start running.
- We recommend to add an anti-corrosion agent via the filling neck at the rear side of the unit.
CAUTION:
SHOULD THE WATER BE FILLED IN MANUALLY, IT HAS TO
BE CONSIDERED THAT NO WATER WITH CHLORIDE
ADDITIVES SHOUD BE USED. IT IS ALSO FORBIDDEN TO USE
SOLVENTS (FOR EXAMPLE PETROL, TOLUOL, NITRO
THINNER, ETC.)
Manual filling for oil operation:
- The unit has to be connected hydraulically and electrically.
DANGER!
WHEN OPERATING WITH OIL THE BALL VALVE OF THE
AUTOMATIC FILLING HAS TO BE CLOSED (SEE CHAPTER 15).
- Switch the unit on.
- If there is not enough oil in the unit (minimum level not reached) the unit does not start
and the two yellow lamps "level control" are lit.
- Fill oil via the filling neck at the rear side of the unit.
Use a funnel tube to prevent to oil from spilling.
Spilled oil has to be removed immediately and disposed appropriately.
- Fill in the oil till the upper level of the unit is reached and therefore both yellow lamps of the level
control are not lit anymore and the permanent sound of the alarm (in case that it is set to ON)
does not ring anymore. Only when the minimum level in the system is reached, the pump starts.
By pumping away the oil to the consumer the possibility exists that the above lamp
"level control" is lit again (pre-warning) and the horn starts ringing. In this case oil has to be filled in
till the upper level of the system has been reached again.
CAUTION!
- THE FILLING AMOUNT MUST NOT BE EXCEEDED TO
PROVIDE THE BIGGEST POSSIBLE EXPANSION AND
RECIRCULATING VOLUME.
- THE FILLING AMOUNT IS RELATED TO AN AMBIENT
TEMPERATURE OF APPROX. +20°C.
- OVERFLOWN OIL HAS TO BE REMOVED IMMEDIATELY
AND HAS TO BE DISPOSED AS PRESCRIBED BY LAW.
- NEVER LET ANY OIL COME INTO THE SEWAGE SYSTEM
OR SOIL.

Manual TT-180 - 7 -
4.4 Pump rotation check
As soon as the unit has been connected to the mains, hose connections have been mounted and the heat
transfer liquid has been added, the direction of the pump rotation must be checked. The direction of rotation
must be clockwise as shown by the arrow on the ventilation cover.
The direction of rotation can be determined by looking through the ventilation slots.
If the direction of rotation is anti-clockwise invert two phases on the electrical connection.
This has to be done by a competent electrician.
You can also, after the unit has been started, check on the rear side of the unit on the manometer if the
pump is running in the correct direction. If the manometer shows a positive pressure, the pump is running
correctly. If a negative pressure is indicated, two phases on the electrical connection have to be inverted.
This has to be done by a competent electrician.
5. Heat transfer liquid
The unit can be switched from 9 kW heating power for water operation to 3 kW heating power for oil
operation (see chapter 6.5 and change over instructions in chapter 15).
5.1 Water
With 9 kW heating power the unit is for use with water as heat transfer liquid.
The tank can be filled manually or automatically.
CAUTION!
DO NOT USE HEAT TRANSFER OILS OR HEAT TRANSFER
MEDIUM WTF-3 (RESP. POLYGLYCOL) WITH 9 KW HEATING
POWER BECAUSE OF TOO HIGH THERMAL LOAD (CRACKING
OF OIL OR DECOMPOSING OF WTF-3 (RESP. POLYGLYCOL)).
5.2 Heat transfer oil
When using the unit with 3 kW heating power it can be operated with mineral heat transfer oils such as
BP Transcal N, Mobiltherm 605, Shell Thermia Oil B etc. Heat transfer medium WTF-3 resp. polyglycol
can also be used. WTF-3 (resp. polyglykol) affects lacquers and colours, and therefore is not recommended
by TOOL-TEMP AG.
CAUTION!
TOOL-TEMP AG DOES NOT RECOMMEND WTF-3
(RESP. POLYGLYCOL) BECAUSE THIS LIQUID
CORRODES LACQUERS AND COLOURS.
The tank has to be filled manually.
DANGER!
THE USE OF UNSUITABLE OIL SORTS IS NOT PERMITTED
AND IS NOT REGARDED AS USE AS AGREED.
PARTICULALLY DANGEROUS AND THEREFOR PROHIBITED
IS THE USE OF INFLAMMABLE SUBSTANCES.
The used heat transfer oil has to be taken down in a check list. Particularly the maximum operating
temperature according to the specifications of the heat transfer oil manufacturer has to be taken down.

6. Operations
For the operating and display elements on the temperature control units see chapter 13 "temperature
controller MP-888 for temperature control units".
6.1 Setting of the temperature
The required temperature on the temperature controller can be adjusted by pressing the flashes
CAUTION!
PAY ATTENTION TO THE MAXIMUM ALLOWED
TEMPERATURES FOR THE USED HEAT TRANSFER
LIQUID AND HOSES.
The lamp in the green switches „heating I – II“ and the red diode in the controller indicate that the operation
mode is HEATING.
Likewise the operating mode COOLING is indicated by the green diode in the temperature controller.
The end user can choose himself if he likes to work with degree Celsius or degree Fahrenheit. When putting
into service the controller the temperature unit will be shown for a short moment.
See instructions „Programming: Temperature controller MP-888“ for details about function and setting
of the controller (see chapter 13).
6.2 Change over of the heating power
Only with a few modifications the unit can be switched over from 9 kW water operation to 3 kW oil operation
and inverse. For the instructions please see chapter 15.
DANGER!
WHEN OPERATING WITH OIL THE BALL VALVE OF THE
AUTOMATIC FILLING HAS TO BE CLOSED (SEE CHAPTER 15).
DANGER!
THE CHANGE FROM WATER TO OIL OPERATION HAS TO BE
DONE VERY CAREFULLY. THE UNIT AND THE PROCESS
MUST BE ABSOLUTELY FREE OF WATER. ONLY A FEW
DROPS OF WATER ARE ENOUGH TO LET THE UNIT EMPTY
BY EXPLOSION AT THE BOILING POINT OF THE WATER.
The change from oil to water operation on the other hand does not need any special measures.
Remaining oil in the water does not cause any problems.

7. Safety devices
7.1 Pump
The pump motor is fitted with an overload relay.
7.2 Heating
In the electronic controller the maximum temperature is limited at +150°C.
DANGER:
IT IS NOT ALLOWED TO ADJUST HIGHER TEMPERATURES
THAN 150°C. LOWER TEMPERATURES ARE ALLOWED;
SPECIALLY FOR WATER OPERATION WE RECOMMEND TO
ADJUST THE MAXIMUM VALUES TO 90 – 95°C (DEPENDING
ON THE LOCATION, HIGHT ABOVE SEE LEVEL, THAT HAS
INFLUENCES THE BOILING POINT OF THE WATER).
Exceeding this temperature the heaters switch off.
The temperature of +150°C can be adjusted according to the information sheet „Programming: Temperature
Controller MP-888“.
The mechanical safety thermostat is set to the maximum allowed temperature of approx. +155°C.
Exceeding this temperature the unit stops.
As soon as the temperature falls to approx. +140°C the heaters switch on automatically.
At water operation the maximum temperature on the controller has to be adjusted to +90°C. (Program step
no. 1). The mechanical safety thermostat can be adjusted to +95°C.
8. Monitoring devices
8.1 Level control
The temperature control unit is equipped with two level controls. The yellow lamp above is lit and the
horn (continuous sound) is activated in case that the level is too low.
During water operation the automatic water refill corrects the level. During oil operation oil has to be refilled
on the rear side of the unit.
The unit is still working. The alarm can be set OFF by pressing the horn switch .
If further 2 litres are missing, both lamps are lit. The horn rings with an intermittent sound and the
unit stops. The alarm can be set OFF by pressing the horn switch .
