1.3. Intended Use The TOOL-TEMP temperature control unit is built according to the current state of the art and the generally accepted principles of safety engineering. The temperature control unit is intended solely for the normal use for heating and/or cooling of injection and die casting moulds, extruders, calendars, mixers and other consumers in areas in which there is no risk of explosion.
Safety Information 1.4.1. General Information The TOOL-TEMP temperature control unit is safe to operate, but this device can pose danger to life and limb if it is used incorrectly or for a purpose other than that intended. It should be noted...
1.4.4. Changing the Parameterisation The parameterisation of the control system may only be carried out by personnel trained by TOOL-TEMP. In particular, no parameters in the device configuration may be changed without consulting TOOL-TEMP. The relevant accident prevention regulations and the generally accepted principles of safety engineering, occupational medicine and structural engineering must be observed.

Manual of instructions TT-188 14/37 5. Installation Before starting the unit the electrical and hydraulic connections have to be installed. The installation of the unit has to be done in the order of the following chapters. After the proper installation the unit is ready to use.
Manual of instructions TT-188 15/37 The temperature control unit is designed for an ambient temperature of +10 up to 40°C. Sufficient ventilation must be ensured during set-up. The distance between the temperature control unit and other facilities must be at least 10cm. The ventilation opening must be free.
Manual of instructions TT-188 16/37 For the cooling water connections it’s enough to use pressure- and temperature-resistant rubber hoses. The tap water pressure has to be between 2,0 and 5,0 bar. We recommend to conduct the water from the unit (cooling water outlet) to an unpressurized outlet.
Manual of instructions TT-188 17/37 5.4.1. Pump rotation check At the rear side of the unit the direction of rotation can be checked. The unit has been connected to the main supply, hoses must be mounted and heat transfer medium has been filled. Identify the sense of rotation of the motor by switching it on shortly.
Manual of instructions TT-188 18/37 5.5. Initial operation with heat transfer oil (Oil operation) The temperature control unit can also be operated with heat transfer oil. The unit must be prepared accordingly for this operation and after this the unit can be filled manually through the filler neck. A guideline for the required filling amount can be taken from the technical data.
Manual of instructions TT-188 19/37 6. Operations The unit is controlled by the temperature controller MP-888. The temperature controller MP-888 is a universal controller for all TOOL-TEMP units. 6.1. Overview MP-888 Display of set value Display of actual value Flow control Display of the current flow in litres/min, English or American gallons/min.
