At higher temperatures vaporization losses occur. In this case use a bath cover (
Ì
9). Use distilled water or pure
demineralized water only after adding 0.1 g of soda (Na
2
CO
3
sodium carbonate) per liter of water. Otherwise there
is the risk of corrosion!
The proportion of water reduces with longer working at high temperatures and the mixture becomes flammable
(flash point 128 °C). Check the mixing ratio using a hydrometer.
Do not use in conjunction with EPDM hose.
Never use silicone oil with silicone hoses.
EPDM hose is not suitable for Ultra 350 nor for mineral oils.
−
When choosing the heat transfer liquid, it must be noted that at the lower limit of the operating tempera-
ture range impairment of the heat transfer properties is to be expected due to the increasing viscosity.
Therefore, only use the full operating temperature range where necessary.
−
The working ranges of the heat carrier liquids and hoses are general figures which can be tightened due
to the operating temperature range of the devices.
−
Never use contaminated heat transfer liquids. Contamination of the pump chamber may lead to the pump
jamming and the device then switching off.
−
Pay attention to the safety data sheet for the heat transfer liquid.
−
Follow the regulations for disposal of the used heat transfer liquid.
If required, you can request the safety data sheets at any time.
