Please note the following:
n
To prevent damage to the consuming unit, open the bypass adjusting
wheel on the back of the device to the full extent before switching on.
Turn the wheel counterclockwise to do this.
n
Temperature control hoses: Always use the largest possible diameters
and shortest possible hoses in the external circuit.
If the temperature control hose diameter is too narrow, the insufficient
flow rate will cause a drop in temperature between the device and
the external consuming unit. In this case, increase or decrease the
temperature accordingly.
n
Secure the temperature control hoses using hose clips.
n
When external consuming units are positioned higher than the device,
the external volume may run dry when the pump is switched off and air
enters the external fluid circuit, even when the circuits are closed. There
is then a danger that the device will overflow.
n
If a hose breaks hot liquids may leak out, thus endangering people and
materials.
4.3 Cooling water
4.3.1 Cooling water requirements
This section is relevant for:
n
Water-cooled devices
NOTICE!
Risk of cooling circuit leaking due to corrosion
Device damage

Do not use corrosive cooling water.
Cooling water is subject to specific purity requirements. A suitable procedure
must be employed to purify the cooling water in line with the contamination
in the water and maintain the water quality. Unsuitable cooling water may
cause the condenser and the entire cooling water circuit to become blocked
or damaged, or start to leak. The entire cooling circuit and cooling water
circuit may sustain extensive consequential damage as a result.
n
Free chlorine consisting of disinfectant, for example, and water con-
taining chloride will cause pitting corrosion in the cooling water circuit.
n
Distilled, deionized and demineralized water are unsuitable due to their
reactivity and will cause corrosion in the cooling water circuit.
n
Sea water is unsuitable due to its corrosive properties and will cause
corrosion in the cooling water circuit.
n
Iron particles and water containing iron will cause corrosion in the
cooling water circuit.
