Range of Application

This general safety information is generally valid for all temperature con-

trollers and control systems from Regloplas.

Intended Use

The Regloplas temperature control unit is built according to the current

state of the art and the generally accepted principles of safety engineer-

ing. The temperature control unit is intended solely for the normal use for

heating and/or cooling of injection moulds and die casting dies, extruders,

calenders, mixers and other consumers in areas where there is no risk of

explosion.

Any use beyond this shall be deemed to constitute improper use. The

manufacturer is not responsible for damage resulting from improper use;

the user is solely responsible for such risks. The temperature control unit

may not be used under other operating conditions and/or with other me-

dia, in deviation from our specifications, without the prior consent of Re-

gloplas AG.

The intended use also entails compliance with the operating, servicing

and maintenance conditions stipulated by the manufacturer. The tem-

perature control unit may only be operated, serviced and maintained by

personnel who are familiar with these tasks and have been instructed as

to the risks.

Safety Information

General Information

The Regloplas temperature control unit is safe to operate but can cause

danger if it is used incorrectly or for a purpose other than its intended

use. It should be noted that any such incorrect use or non-compliance

with the intended use can cause risks to the life and limb of the user or

third parties, adverse effects on the equipment and other material assets

belonging to the user, and risks to the efficient operation of the equip-

ment.

Start-up (i.e., commencement of intended use) is prohibited until it has

been determined that the temperature control unit has been set up and

wired in accordance with the Machinery Directive (2006/42/EC).

EN 60204-1 (Safety of Machinery) must also be observed.

These operating instructions must be read carefully before switching on

and operating the temperature control unit. The information regarding the

intended use and foreseeable misuse must be observed. Local safety re-

gulations must also be obeyed.

If the temperature control unit is used in combination with products made

by other manufacturers, the notices and safety regulations of these ma-

nufacturers must also be obeyed.

Process Monitoring

In plants in which a malfunction of the temperature control system leads

to endangerment of the operating personnel or destruction of the plant,

V 09/2011

Temperature Control Unit 300L(D)/350L(D) General Safety Information •3

an independent process monitor that reliably shuts down the plant must

be used.

Information for Operators and Personnel

The operator and all persons who are tasked with working on the tem-

perature control unit must obey the fundamental regulations regarding

work safety and accident prevention. The operator must ensure that only

persons who have read and understood these operating instructions, in

particular the chapter on safety, may work on the temperature control

unit.

Any working methods that have a negative effect on the technical safety

of the temperature control unit must not be used. The operator must en-

sure that the temperature control unit is operated only in flawless condi-

tion. If necessary, the company using the equipment must obligate the

operating personnel to wear protective clothing.

For all tasks relating to set-up, start-up, operating, modification of operat-

ing conditions and operational methods, maintenance, inspection and re-

pair, any shut-down procedures stated to be necessary in the operating

instructions must be followed.

Changing the Parameter Settings

The parameterisation of the control system may only be carried out by

personnel trained by Regloplas. In particular, no parameters in the device

configuration may be changed without consulting Regloplas.

The relevant accident prevention regulations and the generally accepted

principles of safety engineering, occupational medicine and structural en-

gineering must be observed. The national safety regulations must also be

obeyed.

Residual Risks

Any unauthorised modifications and changes to the temperature control

unit as well as unauthorised changes to the parameterisation of the con-

trol system are prohibited for reasons of safety.

If the temperature control unit is damaged, it must not remain in use; the

defective part must be replaced or repaired immediately. Only original

Regloplas replacement parts may be used. Damage due to use of third-

party parts voids any and all warranty claims.

DANGER

The temperature control unit must be disconnected from the electrical power

supply before it is opened (unplug the mains plug and, if fitted, press the main

switch on the temperature control unit). Danger of electric shock!

Any leaks in the temperature control circuit (device, connecting lines,

consumers, etc.) must be repaired immediately.

In the case of temperature control units that use oil as the heat transfer

medium, please remember that oil is flammable under certain conditions.

For this reason, the temperature control unit must not be located close to

heat sources. The thermal insulation in the device must always be kept

clean. Insulation that is soaked with thermal oil poses an increased risk of

fire.

V 09/2011

4 •General Safety Information Temperature Control Unit 300L(D)/350L(D)

Burning thermal oil can be extinguished using an AFFF spray foam fire

extinguisher, a powder fire extinguisher (to be avoided in the case of

dust-sensitive plants, control systems, EDP, etc.) or a CO2fire extin-

guisher. The appropriate fire extinguisher must be provided by the opera-

tor, taking into account the equipment located in the room and the man-

datory safety regulations.

The temperature control unit may only be operated when all safety sys-

tems are completely installed and intact.

The temperature control unit must be protected against sprays and clean-

ing agents.

Before detaching connecting lines from the temperature control circuit

and depending on the outlet temperature, allow the temperature control

unit to cool down first and then switch it off. Check that the pump is no

longer running.

WARNING

Important - danger of injury in the event of escaping water or oil!

6 •Operating Instructions Temperature Control Unit 300L(D)/350L(D)

Start-up

Setting up the Temperature Control Unit

The temperature control unit is designed for an ambient temperature ran-

ge of 10-40 °C. Sufficient ventilation must be ensured during set-up. The

distance between the devices and/or between the temperature control

unit and a wall must be at least 10 cm. The ventilation slits must not be

covered.

•Check the temperature control unit to ensure that it is undam-

aged and complete

•Do not tip the temperature control unit! Heat transfer medium

remaining in the unit from the test run could spill, and there is a

risk that the thermal insulation could become soaked with the flu-

id (medium)

•Position the temperature control unit on a horizontal surface and

engage the wheel brake

WARNING

Never start up the temperature control unit without the side panels and housing!

Never use the temperature control unit in potentially explosive environments and

protect it against sprays and cleaning agents that contain solvents!

Do not place the temperature control unit close to sources of heat (e.g. furnaces

in die-casting plants)!

Any leaks in the temperature control circuit (temperature control unit, connecting

lines, consumers, etc.) must be repaired immediately!

The thermal insulation in the temperature control unit must be kept clean at all

times (thermal insulation soaked with thermal oil is a fire risk)!

Observe local laws during set-up!

CAUTION

Danger of injury due to release of hot thermal oil!

Before detaching connecting lines in the temperature control circuit, the tem-

perature control unit must first be allowed to cool down. The cooling time will

depend on the outlet temperature. The shutdown procedure is initiated by press-

ing the ON/OFF button. The pump continues to run. The temperature control unit

cools down until the temperature of the heat transfer medium has reached the

programmed coastdown temperature (factory default 60 °C). The pump and the

control system are then switched off!

Check that the pump is no longer running (indicator in the display = OFF)!

NOTE

Burning thermal oil can be extinguished using an AFFF spray foam fire extin-

guisher, a powder fire extinguisher (to be avoided in the case of dust-sensitive

plants, control systems, EDP, etc.) or a CO2 fire extinguisher (danger of reigni-

tion, limited suitability).

The appropriate fire extinguisher must be provided by the operator, taking into

account the equipment located in the room and the mandatory safety regula-

tions.
