Safety information
YAUE0007 / 2/26/2009
•
With the use of thermostats as circulating thermostats hot or cold liquid can be emitted when the hose
breaks, presenting a hazard to persons and material.
•
If no external load is connected, the pump outflow must be closed (use screw plugs) and the bypass
valve must be set to "internal"
Ö
•
Take into account the thermal expansion of the heat transfer oils with increasing bath temperature.
•
Depending on the heat transfer liquid used and the type of operation, toxic vapors can arise. Ensure
suitable extraction.
•
By changing the heat transfer liquid from aqueous heat transfer liquid to a thermal transfer liquid for
temperatures above 100°C, carefully remove all water residues, including from the hoses and loads.
When doing this, also open the blanking caps of the pump outputs and inputs and blow
compressed air through all the pump outputs and inputs.
Æ
Danger of scald due to delay in
boiling!
•
Withdraw the mains plug before cleaning, maintenance or moving the thermostat.
•
Specialist personnel must only carry out repairs in the control section.
•
The following action may start the thermostat unintentionally from the standby mode: Previously
activated timer mode (

•
Figures of temperature constancy and display accuracy apply under normal conditions according to
DIN 12876. Electromagnetic high frequency fields may in special cases lead to unfavorable values.
Safety is not impaired.
Only water-cooled devices:
•
The return hose of the water cooling must be securely fixed on the outlet port in order to prevent the
hose sliding off uncontrollably, also during pressure surges.
•
The return hose of the water cooling must be fixed on the outlet port that hot cooling water cannot
splash out.
•
It is essential to prevent kinking or squashing of the return hose for the water cooling. Excessive
pressure can cause the cooling water hoses to tear and hot water to escape.
•
To prevent damages by a leakage of the cooling water system its recommended to use a leak-water
detector with shut-off valve (Aqua Stop).
